QWeb Reports¶
Reports are written in HTML/QWeb, like website views in Odoo. You can use the usual QWeb control flow tools. The PDF rendering itself is performed by wkhtmltopdf.
Reports are declared using a report action, and a Report template for the action to use.
If useful or necessary, it is possible to specify a Paper Format for the report report.
Report template¶
Report templates will always provide the following variables:
time
a reference to
time
from the Python standard libraryuser
res.user
record for the user printing the reportres_company
record for the current
user
’s companywebsite
the current website object, if any (this item can be present but
None
)web_base_url
the base url for the webserver
context_timestamp
a function taking
datetime.datetime
in UTC1 and converting it to the timezone of the user printing the report
Minimal viable template¶
A minimal template would look like:
<template id="report_invoice">
<t t-call="web.html_container">
<t t-foreach="docs" t-as="o">
<t t-call="web.external_layout">
<div class="page">
<h2>Report title</h2>
<p>This object's name is <span t-field="o.name"/></p>
</div>
</t>
</t>
</t>
</template>
Calling external_layout
will add the default header and footer on your
report. The PDF body will be the content inside the <div
class="page">
. The template’s id
must be the name specified in the
report declaration; for example account.report_invoice
for the above
report. Since this is a QWeb template, you can access all the fields of the
docs
objects received by the template.
By default, the rendering context will also expose the following items:
docs
records for the current report
doc_ids
list of ids for the
docs
recordsdoc_model
model for the
docs
records
If you wish to access other records/models in the template, you will need a custom report, however in that case you will have to provide the items above if you need them.
Translatable Templates¶
If you wish to translate reports (to the language of a partner, for example), you need to define two templates:
The main report template
The translatable document
You can then call the translatable document from your main template with the attribute
t-lang
set to a language code (for example fr
or en_US
) or to a record field.
You will also need to re-browse the related records with the proper context if you use
fields that are translatable (like country names, sales conditions, etc.)
Atenționare
If your report template does not use translatable record fields, re-browsing the record in another language is not necessary and will impact performances.
For example, let’s look at the Sale Order report from the Sale module:
<!-- Main template -->
<template id="report_saleorder">
<t t-call="web.html_container">
<t t-foreach="docs" t-as="doc">
<t t-call="sale.report_saleorder_document" t-lang="doc.partner_id.lang"/>
</t>
</t>
</template>
<!-- Translatable template -->
<template id="report_saleorder_document">
<!-- Re-browse of the record with the partner lang -->
<t t-set="doc" t-value="doc.with_context(lang=doc.partner_id.lang)" />
<t t-call="web.external_layout">
<div class="page">
<div class="oe_structure"/>
<div class="row">
<div class="col-6">
<strong t-if="doc.partner_shipping_id == doc.partner_invoice_id">Invoice and shipping address:</strong>
<strong t-if="doc.partner_shipping_id != doc.partner_invoice_id">Invoice address:</strong>
<div t-field="doc.partner_invoice_id" t-options="{"no_marker": True}"/>
<...>
<div class="oe_structure"/>
</div>
</t>
</template>
The main template calls the translatable template with doc.partner_id.lang
as a
t-lang
parameter, so it will be rendered in the language of the partner. This way,
each Sale Order will be printed in the language of the corresponding customer. If you wish
to translate only the body of the document, but keep the header and footer in a default
language, you could call the report’s external layout this way:
<t t-call="web.external_layout" t-lang="en_US">
Sfat
Please take note that this works only when calling external templates, you will not be
able to translate part of a document by setting a t-lang
attribute on an xml node other
than t-call
. If you wish to translate part of a template, you can create an external
template with this partial template and call it from the main one with the t-lang
attribute.
Barcodes¶
Barcodes are images returned by a controller and can easily be embedded in reports thanks to the QWeb syntax (e.g. see attributes):
<img t-att-src="'/report/barcode/QR/%s' % 'My text in qr code'"/>
More parameters can be passed as a query string
<img t-att-src="'/report/barcode/?
type=%s&value=%s&width=%s&height=%s'%('QR', 'text', 200, 200)"/>
Useful Remarks¶
Twitter Bootstrap and FontAwesome classes can be used in your report template
Local CSS can be put directly in the template
Global CSS can be inserted in the main report layout by inheriting its template and inserting your CSS:
<template id="report_saleorder_style" inherit_id="report.style"> <xpath expr="."> <t> .example-css-class { background-color: red; } </t> </xpath> </template>
If it appears that your PDF report is missing the styles, please check these instructions.
Paper Format¶
Paper formats are records of report.paperformat
and can contain the
following attributes:
name
(mandatory)only useful as a mnemonic/description of the report when looking for one in a list of some sort
description
a small description of your format
format
either a predefined format (A0 to A9, B0 to B10, Legal, Letter, Tabloid,…) or
custom
; A4 by default. You cannot use a non-custom format if you define the page dimensions.dpi
output DPI; 90 by default
margin_top
,margin_bottom
,margin_left
,margin_right
margin sizes in mm
page_height
,page_width
page dimensions in mm
orientation
Landscape or Portrait
header_line
boolean to display a header line
header_spacing
header spacing in mm
Example:
<record id="paperformat_frenchcheck" model="report.paperformat">
<field name="name">French Bank Check</field>
<field name="default" eval="True"/>
<field name="format">custom</field>
<field name="page_height">80</field>
<field name="page_width">175</field>
<field name="orientation">Portrait</field>
<field name="margin_top">3</field>
<field name="margin_bottom">3</field>
<field name="margin_left">3</field>
<field name="margin_right">3</field>
<field name="header_line" eval="False"/>
<field name="header_spacing">3</field>
<field name="dpi">80</field>
</record>
Custom Reports¶
By default, the reporting system builds rendering values based on the target
model specified through the model
field.
However, it will first look for a model named
report.module.report_name
and call that model’s
_get_report_values(doc_ids, data)
in order to prepare the rendering data for
the template.
This can be used to include arbitrary items to use or display while rendering the template, such as data from additional models:
from odoo import api, models
class ParticularReport(models.AbstractModel):
_name = 'report.module.report_name'
def _get_report_values(self, docids, data=None):
# get the report action back as we will need its data
report = self.env['ir.actions.report']._get_report_from_name('module.report_name')
# get the records selected for this rendering of the report
obj = self.env[report.model].browse(docids)
# return a custom rendering context
return {
'lines': docids.get_lines()
}
Atenționare
When using a custom report, the „default” document-related items
(doc_ids
, doc_model
and docs
) will not be included. If you
want them, you will need to include them yourself.
In the example above, the rendering context will contain the „global” values
as well as the lines
we put in there but nothing else.
Custom fonts¶
If you want to use custom fonts you will need to add your custom font and the related less/CSS to the web.reports_assets_common
assets bundle.
Adding your custom font(s) to web.assets_common
or web.assets_backend
will not make your font available in QWeb reports.
Example:
<template id="report_assets_common_custom_fonts" name="Custom QWeb fonts" inherit_id="web.report_assets_common">
<xpath expr="." position="inside">
<link href="/your_module/static/src/less/fonts.less" rel="stylesheet" type="text/less"/>
</xpath>
</template>
You will need to define your @font-face
within this less file, even if you’ve used in another assets bundle (other than web.reports_assets_common
).
Example:
@font-face {
font-family: 'MonixBold';
src: local('MonixBold'), local('MonixBold'), url(/your_module/static/fonts/MonixBold-Regular.otf) format('opentype');
}
.h1-title-big {
font-family: MonixBold;
font-size: 60px;
color: #3399cc;
}
After you’ve added the less into your assets bundle you can use the classes - in this example h1-title-big
- in your custom QWeb report.
Reports are web pages¶
Reports are dynamically generated by the report module and can be accessed directly via URL:
For example, you can access a Sale Order report in html mode by going to http://<server-address>/report/html/sale.report_saleorder/38
Or you can access the pdf version at http://<server-address>/report/pdf/sale.report_saleorder/38

it does not matter what timezone the
python:datetime
object is actually in (including no timezone), its timezone will unconditionally be set to UTC before being adjusted to the user’s
