Odoo Guidelines

This page introduces the new Odoo Coding Guidelines. Those aim to improve the quality of the code (e.g. better readability of source) and Odoo Apps. Indeed, proper code eases maintenance, aids debugging, lowers complexity and promotes reliability.

These guidelines should be applied to every new module, and new developpment. These guidelines will be applied to old module only in case of code refactoring (migration to new API, big refactoring, ...).

Module structure

Directories

A module is organised in important directories. Those contain the business logic; having a look at them should make understand the purpose of the module.

  • data/ : demo and data xml
  • models/ : models definition
  • controllers/ : contains controllers (HTTP routes).
  • views/ : contains the views and templates
  • static/ : contains the web assets, separated into css/, js/, img/, lib/, ...

Other optional directories compose the module.

  • wizard/ : regroups the transient models (formerly osv_memory) and their views.
  • report/ : contains the reports (RML report [deprecated], models based on SQL views (for reporting) and other complex reports). Python objects and XML views are included in this directory.
  • tests/ : contains the Python/YML tests

File naming

For views declarations, split backend views from (frontend) templates in 2 differents files.

For models, split the business logic by sets of models, in each set select a main model, this model gives its name to the set. If there is only one model, its name is the same as the module name. For each set named <main_model> the following files may be created:

  • models/<main_model>.py
  • models/<inherited_main_model>.py
  • views/<main_model>_templates.xml
  • views/<main_model>_views.xml

For instance, sale module introduces sale_order and sale_order_line where sale_order is dominant. So the <main_model> files will be named models/sale_order.py and views/sale_order_views.py.

For data, split them by purpose : demo or data. The filename will be the main_model name, suffixed by _demo.xml or _data.xml.

For controllers, the only file should be named main.py. Otherwise, if you need to inherit an existing controller from another module, its name will be <module_name>.py. Unlike models, each controller class should be contained in a separated file.

For static files, since the resources can be used in different contexts (frontend, backend, both), they will be included in only one bundle. So, CSS/Less, JavaScript and XML files should be suffixed with the name of the bundle type. i.e.: im_chat_common.css, im_chat_common.js for 'assets_common' bundle, and im_chat_backend.css, im_chat_backend.js for 'assets_backend' bundle. If the module owns only one file, the convention will be <module_name>.ext (i.e.: project.js). Don't link data (image, libraries) outside Odoo: do not use an URL to an image but copy it in our codebase instead.

Regarding data, split them by purpose: data or demo. The filename will be the main_model name, suffixed by _data.xml or _demo.xml.

Regarding wizards, naming convention is :

  • <main_transient>.py
  • <main_transient>_views.xml

Where <main_transient> is the name of the dominant transient model, just like for models. <main_transient>.py can contains the models 'model.action' and 'model.action.line'.

For statistics reports, their names should look like :

  • <report_name_A>_report.py
  • <report_name_A>_report_views.py (often pivot and graph views)

For printable reports, you should have :

  • <print_report_name>_reports.py (report actions, paperformat definition, ...)
  • <print_report_name>_templates.xml (xml report templates)

The complete tree should look like

addons/<my_module_name>/

|   |-- __init__.py

XML files

Format

To declare a record in XML, the record notation (using <record>) is recommended:

  • Place id attribute before model
  • For field declaration, name attribute is first. Then place the value either in the field tag, either in the eval attribute, and finally other attributes (widget, options, ...) ordered by importance.
  • Try to group the record by model. In case of dependencies between action/menu/views, this convention may not be applicable.
  • Use naming convention defined at the next point
  • The tag <data> is only used to set not-updatable data with noupdate=1
<record id="view_id" model="ir.ui.view">
    <field name="name">view.name</field>
    <field name="model">object_name</field>
    <field name="priority" eval="16"/>
    <field name="arch" type="xml">
        <tree>
            <field name="my_field_1"/>
            <field name="my_field_2" string="My Label" widget="statusbar" statusbar_visible="draft,sent,progress,done" />
        </tree>
    </field>
</record>

Odoo supports custom tags acting as syntactic sugar:

  • menuitem: use it as a shortcut to declare a ir.ui.menu
  • workflow: the <workflow> tag sends a signal to an existing workflow.
  • template: use it to declare a QWeb View requiring only the arch section of the view.
  • report: use to declare a report action
  • act_window: use it if the record notation can't do what you want

The 4 first tags are prefered over the record notation.

Naming xml_id

Security, View and Action

Use the following pattern :

  • For a menu: <model_name>_menu
  • For a view: <model_name>_view_<view_type>, where view_type is kanban, form, tree, search, ...
  • For an action: the main action respects <model_name>_action. Others are suffixed with _<detail>, where detail is a lowercase string briefly explaining the action. This is used only if multiple actions are declared for the model.
  • For a group: <model_name>_group_<group_name> where group_name is the name of the group, generally 'user', 'manager', ...
  • For a rule: <model_name>_rule_<concerned_group> where concerned_group is the short name of the concerned group ('user' for the 'model_name_group_user', 'public' for public user, 'company' for multi-company rules, ...).
  • For a group : <model_name>_group_<group_name> where group_name is the name of the group, generally 'user', 'manager', ...
<!-- views and menus -->
<record id="model_name_view_form" model="ir.ui.view">
    ...
</record>

<record id="model_name_view_kanban" model="ir.ui.view">
    ...
</record>

<menuitem
    id="model_name_menu_root"
    name="Main Menu"
    sequence="5"
/>
<menuitem
    id="model_name_menu_action"
    name="Sub Menu 1"
    parent="module_name.module_name_menu_root"
    action="model_name_action"
    sequence="10"
/>

<!-- actions -->
<record id="model_name_action" model="ir.actions.act_window">
    ...
</record>

<record id="model_name_action_child_list" model="ir.actions.act_window">
    ...
</record>

<!-- security -->
<record id="module_name_group_user" model="res.groups">
    ...
</record>

<record id="model_name_rule_public" model="ir.rule">
    ...
</record>

<record id="model_name_rule_company" model="ir.rule">
    ...
</record>

Inherited XML

The naming pattern of inherited view is <base_view>_inherit_<current_module_name>. A module may only extend a view once. Suffix the orginal name with _inherit_<current_module_name> where current_module_name is the technical name of the module extending the view.

<record id="inherited_model_view_form_inherit_my_module" model="ir.ui.view">
    ...
</record>

Python

PEP8 options

Using a linter can help show syntax and semantic warnings or errors. Odoo source code tries to respect Python standard, but some of them can be ignored.

  • E501: line too long
  • E301: expected 1 blank line, found 0
  • E302: expected 2 blank lines, found 1
  • E126: continuation line over-indented for hanging indent
  • E123: closing bracket does not match indentation of opening bracket's line
  • E127: continuation line over-indented for visual indent
  • E128: continuation line under-indented for visual indent
  • E265: block comment should start with '# '

Imports

The imports are ordered as

  1. External libraries (one per line sorted and split in python stdlib)
  2. Imports of odoo
  3. Imports from Odoo modules (rarely, and only if necessary)

Inside these 3 groups, the imported lines are alphabetically sorted.

# 1 : imports of python lib
import base64
import re
import time
from datetime import datetime
# 2 :  imports of odoo
import odoo
from odoo import api, fields, models # alphabetically ordered
from odoo.tools.safe_eval import safe_eval as eval
from odoo.tools.translate import _
# 3 :  imports from odoo modules
from odoo.addons.website.models.website import slug
from odoo.addons.web.controllers.main import login_redirect

Idiomatics Python Programming

  • Each python file should have # -*- coding: utf-8 -*- as first line.
  • Always favor readability over conciseness or using the language features or idioms.
  • Don't use .clone()
# bad
new_dict = my_dict.clone()
new_list = old_list.clone()
# good
new_dict = dict(my_dict)
new_list = list(old_list)
  • Python dictionary : creation and update
# -- creation empty dict
my_dict = {}
my_dict2 = dict()

# -- creation with values
# bad
my_dict = {}
my_dict['foo'] = 3
my_dict['bar'] = 4
# good
my_dict = {'foo': 3, 'bar': 4}

# -- update dict
# bad
my_dict['foo'] = 3
my_dict['bar'] = 4
my_dict['baz'] = 5
# good
my_dict.update(foo=3, bar=4, baz=5)
my_dict = dict(my_dict, **my_dict2)
  • Use meaningful variable/class/method names
  • Useless variable : Temporary variables can make the code clearer by giving names to objects, but that doesn't mean you should create temporary variables all the time:
# pointless
schema = kw['schema']
params = {'schema': schema}
# simpler
params = {'schema': kw['schema']}
  • Multiple return points are OK, when they're simpler
# a bit complex and with a redundant temp variable
def axes(self, axis):
        axes = []
        if type(axis) == type([]):
                axes.extend(axis)
        else:
                axes.append(axis)
        return axes

 # clearer
def axes(self, axis):
        if type(axis) == type([]):
                return list(axis) # clone the axis
        else:
                return [axis] # single-element list
value = my_dict.get('key', None) # very very redundant
value= my_dict.get('key') # good

Also, if 'key' in my_dict and if my_dict.get('key') have very different meaning, be sure that you're using the right one.

  • Learn list comprehensions : Use list comprehension, dict comprehension, and basic manipulation using map, filter, sum, ... They make the code easier to read.
# not very good
cube = []
for i in res:
        cube.append((i['id'],i['name']))
# better
cube = [(i['id'], i['name']) for i in res]
  • Collections are booleans too : In python, many objects have "boolean-ish" value when evaluated in a boolean context (such as an if). Among these are collections (lists, dicts, sets, ...) which are "falsy" when empty and "truthy" when containing items:
bool([]) is False
bool([1]) is True
bool([False]) is True

So, you can write if some_collection: instead of if len(some_collection):.

  • Iterate on iterables
# creates a temporary list and looks bar
for key in my_dict.keys():
        "do something..."
# better
for key in my_dict:
        "do something..."
# creates a temporary list
for key, value in my_dict.items():
        "do something..."
# only iterates
for key, value in my_dict.iteritems():
        "do something..."
  • Use dict.setdefault
# longer.. harder to read
values = {}
for element in iterable:
    if element not in values:
        values[element] = []
    values[element].append(other_value)

# better.. use dict.setdefault method
values = {}
for element in iterable:
    values.setdefault(element, []).append(other_value)

Programming in Odoo

  • Avoid to create generators and decorators: only use the ones provided by the Odoo API.
  • As in python, use filtered, mapped, sorted, ... methods to ease code reading and performance.

Make your method works in batch

When adding a function, make sure it can process multiple records. Typically, such method is decorated with api.multi decorator (or takes a list of id, if written in old api). Then you will have to iterate on self to treat each record.

@api.multi
def my_method(self)
    for record in self:
        record.do_cool_stuff()

Avoid to use api.one decorator : this will probably not do what you expected, and extending a such method is not as easy than a api.multi method, since it returns a list of result (ordered by recordset ids).

For performance issue, when developping a 'stat button' (for instance), do not perform a search or a search_count in a loop in a api.multi method. It is recommended to use read_group method, to compute all value in only one request.

@api.multi
def _compute_equipment_count(self):
""" Count the number of equipement per category """
    equipment_data = self.env['hr.equipment'].read_group([('category_id', 'in', self.ids)], ['category_id'], ['category_id'])
    mapped_data = dict([(m['category_id'][0], m['category_id_count']) for m in equipment_data])
    for category in self:
        category.equipment_count = mapped_data.get(category.id, 0)

Propagate the context

In new API, the context is a frozendict that cannot be modified. To call a method with a different context, the with_context method should be used :

records.with_context(new_context).do_stuff() # all the context is replaced
records.with_context(**additionnal_context).do_other_stuff() # additionnal_context values override native context ones

Passing parameter in context can have dangerous side-effects. Since the values are propagated automatically, some behavior can appears. Calling create() method of a model with default_my_field key in context will set the default value of my_field for the concerned model. But if curing this creation, other object (such as sale.order.line, on sale.order creation) having a field name my_field, their default value will be set too.

If you need to create a key context influencing the behavior of some object, choice a good name, and eventually prefix it by the name of the module to isolate its impact. A good example are the keys of mail module : mail_create_nosubscribe, mail_notrack, mail_notify_user_signature, ...

Do not bypass the ORM

You should never use the database cursor directly when the ORM can do the same thing! By doing so you are bypassing all the ORM features, possibly the transactions, access rights and so on.

And chances are that you are also making the code harder to read and probably less secure.

# very very wrong
self.env.cr.execute('SELECT id FROM auction_lots WHERE auction_id in (' + ','.join(map(str, ids))+') AND state=%s AND obj_price > 0', ('draft',))
auction_lots_ids = [x[0] for x in self.env.cr.fetchall()]

# no injection, but still wrong
self.env.cr.execute('SELECT id FROM auction_lots WHERE auction_id in %s '\
           'AND state=%s AND obj_price > 0', (tuple(ids), 'draft',))
auction_lots_ids = [x[0] for x in self.env.cr.fetchall()]

# better
auction_lots_ids = self.search([('auction_id','in',ids), ('state','=','draft'), ('obj_price','>',0)])

No SQL injections, please !

Care must be taken not to introduce SQL injections vulnerabilities when using manual SQL queries. The vulnerability is present when user input is either incorrectly filtered or badly quoted, allowing an attacker to introduce undesirable clauses to a SQL query (such as circumventing filters or executing UPDATE or DELETE commands).

The best way to be safe is to never, NEVER use Python string concatenation (+) or string parameters interpolation (%) to pass variables to a SQL query string.

The second reason, which is almost as important, is that it is the job of the database abstraction layer (psycopg2) to decide how to format query parameters, not your job! For example psycopg2 knows that when you pass a list of values it needs to format them as a comma-separated list, enclosed in parentheses !

# the following is very bad:
#   - it's a SQL injection vulnerability
#   - it's unreadable
#   - it's not your job to format the list of ids
self.env.cr.execute('SELECT distinct child_id FROM account_account_consol_rel ' +
           'WHERE parent_id IN ('+','.join(map(str, ids))+')')

# better
self.env.cr.execute('SELECT DISTINCT child_id '\
           'FROM account_account_consol_rel '\
           'WHERE parent_id IN %s',
           (tuple(ids),))

This is very important, so please be careful also when refactoring, and most importantly do not copy these patterns!

Here is a memorable example to help you remember what the issue is about (but do not copy the code there). Before continuing, please be sure to read the online documentation of pyscopg2 to learn of to use it properly:

Keep your methods short/simple when possible

Functions and methods should not contain too much logic: having a lot of small and simple methods is more advisable than having few large and complex methods. A good rule of thumb is to split a method as soon as: - it has more than one responsibility (see http://en.wikipedia.org/wiki/Single_responsibility_principle) - it is too big to fit on one screen.

Also, name your functions accordingly: small and properly named functions are the starting point of readable/maintainable code and tighter documentation.

This recommendation is also relevant for classes, files, modules and packages. (See also http://en.wikipedia.org/wiki/Cyclomatic_complexity)

Never commit the transaction

The Odoo framework is in charge of providing the transactional context for all RPC calls. The principle is that a new database cursor is opened at the beginning of each RPC call, and committed when the call has returned, just before transmitting the answer to the RPC client, approximately like this:

def execute(self, db_name, uid, obj, method, *args, **kw):
    db, pool = pooler.get_db_and_pool(db_name)
    # create transaction cursor
    cr = db.cursor()
    try:
        res = pool.execute_cr(cr, uid, obj, method, *args, **kw)
        cr.commit() # all good, we commit
    except Exception:
        cr.rollback() # error, rollback everything atomically
        raise
    finally:
        cr.close() # always close cursor opened manually
    return res

If any error occurs during the execution of the RPC call, the transaction is rolled back atomically, preserving the state of the system.

Similarly, the system also provides a dedicated transaction during the execution of tests suites, so it can be rolled back or not depending on the server startup options.

The consequence is that if you manually call cr.commit() anywhere there is a very high chance that you will break the system in various ways, because you will cause partial commits, and thus partial and unclean rollbacks, causing among others:

  1. inconsistent business data, usually data loss
  2. workflow desynchronization, documents stuck permanently
  3. tests that can't be rolled back cleanly, and will start polluting the database, and triggering error (this is true even if no error occurs during the transaction)
Here is the very simple rule:

You should NEVER call cr.commit() yourself, UNLESS you have created your own database cursor explicitly! And the situations where you need to do that are exceptional!

And by the way if you did create your own cursor, then you need to handle error cases and proper rollback, as well as properly close the cursor when you're done with it.

And contrary to popular belief, you do not even need to call cr.commit() in the following situations: - in the _auto_init() method of an models.Model object: this is taken care of by the addons initialization method, or by the ORM transaction when creating custom models - in reports: the commit() is handled by the framework too, so you can update the database even from within a report - within models.Transient methods: these methods are called exactly like regular models.Model ones, within a transaction and with the corresponding cr.commit()/rollback() at the end - etc. (see general rule above if you have in doubt!)

All cr.commit() calls outside of the server framework from now on must have an explicit comment explaining why they are absolutely necessary, why they are indeed correct, and why they do not break the transactions. Otherwise they can and will be removed !

Use translation method correctly

Odoo uses a GetText-like method named "underscore" _( ) to indicate that a static string used in the code needs to be translated at runtime using the language of the context. This pseudo-method is accessed within your code by importing as follows:

from odoo.tools.translate import _

A few very important rules must be followed when using it, in order for it to work and to avoid filling the translations with useless junk.

Basically, this method should only be used for static strings written manually in the code, it will not work to translate field values, such as Product names, etc. This must be done instead using the translate flag on the corresponding field.

The rule is very simple: calls to the underscore method should always be in the form _('literal string') and nothing else:

# good: plain strings
error = _('This record is locked!')

# good: strings with formatting patterns included
error = _('Record %s cannot be modified!') % record

# ok too: multi-line literal strings
error = _("""This is a bad multiline example
             about record %s!""") % record
error = _('Record %s cannot be modified' \
          'after being validated!') % record

# bad: tries to translate after string formatting
#      (pay attention to brackets!)
# This does NOT work and messes up the translations!
error = _('Record %s cannot be modified!' % record)

# bad: dynamic string, string concatenation, etc are forbidden!
# This does NOT work and messes up the translations!
error = _("'" + que_rec['question'] + "' \n")

# bad: field values are automatically translated by the framework
# This is useless and will not work the way you think:
error = _("Product %s is out of stock!") % _(product.name)
# and the following will of course not work as already explained:
error = _("Product %s is out of stock!" % product.name)

# bad: field values are automatically translated by the framework
# This is useless and will not work the way you think:
error = _("Product %s is not available!") % _(product.name)
# and the following will of course not work as already explained:
error = _("Product %s is not available!" % product.name)

# Instead you can do the following and everything will be translated,
# including the product name if its field definition has the
# translate flag properly set:
error = _("Product %s is not available!") % product.name

Also, keep in mind that translators will have to work with the literal values that are passed to the underscore function, so please try to make them easy to understand and keep spurious characters and formatting to a minimum. Translators must be aware that formatting patterns such as %s or %d, newlines, etc. need to be preserved, but it's important to use these in a sensible and obvious manner:

# Bad: makes the translations hard to work with
error = "'" + question + _("' \nPlease enter an integer value ")

# Better (pay attention to position of the brackets too!)
error = _("Answer to question %s is not valid.\n" \
          "Please enter an integer value.") % question

In general in Odoo, when manipulating strings, prefer % over .format() (when only one variable to replace in a string), and prefer %(varname) instead of position (when multiple variables have to be replaced). This makes the translation easier for the community translators.

Symbols and Conventions

  • Model name (using the dot notation, prefix by the module name) :
    • When defining an Odoo Model : use singular form of the name (res.partner and sale.order instead of res.partnerS and saleS.orderS)
    • When defining an Odoo Transient (wizard) : use <related_base_model>.<action> where related_base_model is the base model (defined in models/) related to the transient, and action is the short name of what the transient do. For instance : account.invoice.make, project.task.delegate.batch, ...
    • When defining report model (SQL views e.i.) : use <related_base_model>.report.<action>, based on the Transient convention.
  • Odoo Python Class : use camelcase for code in api v8 (Object-oriented style), underscore lowercase notation for old api (SQL style).
class AccountInvoice(models.Model):
    ...

class account_invoice(osv.osv):
    ...
  • Variable name :
    • use camelcase for model variable
    • use underscore lowercase notation for common variable.
    • since new API works with record or recordset instead of id list, don't suffix variable name with _id or _ids if they not contain id or list of id.
ResPartner = self.env['res.partner']
partners = ResPartner.browse(ids)
partner_id = partners[0].id
  • One2Many and Many2Many fields should always have _ids as suffix (example: sale_order_line_ids)
  • Many2One fields should have _id as suffix (example : partner_id, user_id, ...)
  • Method conventions
    • Compute Field : the compute method pattern is _compute_<field_name>
    • Search method : the search method pattern is _search_<field_name>
    • Default method : the default method pattern is _default_<field_name>
    • Onchange method : the onchange method pattern is _onchange_<field_name>
    • Constraint method : the constraint method pattern is _check_<constraint_name>
    • Action method : an object action method is prefix with action_. Its decorator is @api.multi, but since it use only one record, add self.ensure_one() at the beginning of the method.
  • In a Model attribute order should be
    1. Private attributes (_name, _description, _inherit, ...)
    2. Default method and _default_get
    3. Field declarations
    4. Compute and search methods in the same order as field declaration
    5. Constrains methods (@api.constrains) and onchange methods (@api.onchange)
    6. CRUD methods (ORM overrides)
    7. Action methods
    8. And finally, other business methods.
class Event(models.Model):
    # Private attributes
    _name = 'event.event'
    _description = 'Event'

    # Default methods
    def _default_name(self):
        ...

Javascript and CSS

For javascript :

  • use strict; is recommended for all javascript files
  • Use a linter (jshint, ...)
  • Never add minified Javascript Libraries
  • Use camelcase for class declaration
  • Unless your code is supposed to run on every page, target specific pages using the if_dom_contains function of website module. Target an element which is specific to the pages your code needs to run on using JQuery.
odoo.website.if_dom_contains('.jquery_class_selector', function () {
    /*your code here*/
});

For CSS :

  • Prefix all your classes with o_<module_name> where module_name is the technical name of the module ('sale', 'im_chat', ...) or the main route reserved by the module (for website module mainly, i.e. : 'o_forum' for website_forum module). The only exception for this rule is the webclient: it simply uses o_ prefix.
  • Avoid using id
  • Use Bootstrap native classes
  • Use underscore lowercase notation to name class

Git

Commit message

Prefix your commit with

  • [IMP] for improvements
  • [FIX] for bug fixes
  • [REF] for refactoring
  • [ADD] for adding new resources
  • [REM] for removing of resources
  • [MOV] for moving files (Do not change content of moved file, otherwise Git will loose track, and the history will be lost !), or simply moving code from a file to another one.
  • [MERGE] for merge commits (only for forward/back-port)
  • [CLA] for signing the Odoo Individual Contributor License

Then, in the message itself, specify the part of the code impacted by your changes (module name, lib, transversal object, ...) and a description of the changes.

  • Always include a meaningful commit message: it should be self explanatory (long enough) including the name of the module that has been changed and the reason behind the change. Do not use single words like "bugfix" or "improvements".
  • Avoid commits which simultaneously impact multiple modules. Try to split into different commits where impacted modules are different (It will be helpful if we need to revert a module separately).
[FIX] website, website_mail: remove unused alert div, fixes look of input-group-btn

Bootstrap's CSS depends on the input-group-btn
element being the first/last child of its parent.
This was not the case because of the invisible
and useless alert.

[IMP] fields: reduce memory footprint of list/set field attributes

[REF] web: add module system to the web client

This commit introduces a new module system for the javascript code.
Instead of using global ...
