it's recommended to use github version of odoo for development purposes, follow install from github. follow "Source Install" section here

Temur

as operation system, it's recommended to use Ubuntu linux, if you can use it. if not, then windows is ok also...

Temur

we do everything through modules in odoo. so good starting point for you should be the module tutorial follow it and create some simple module, in order to get familiar with module structure and architecture...

Temur

good luck...

thanks for the fast reply...

here is my code: 

<script type="text/javascript">
from openerp import models, fields, api
class my_sites(models.Model):
_name = 'stock.site'
sitecode = fields.Char(string="Site", size=30, required=True)
name = fields.Char(string="Description", size=60)
warehouse_id = fields.Many2One('stock.warehouse',
ondelete = 'cascade', string = 'Warehouse')
class my_warehouse(models.Model):
_inherit = 'stock.warehouse'
site = fields.One2Many('stock.site', 'site_id', string = 'Site')
</script>

and here is my xml file: 

<script type="text/javascript">
<openerp>
<data> 
<record model="ir.ui.view" id="site_tree_view">
<field name="name">my.site.view</field>
<field name="model">my.site</field>
<field name="arch" type="xml">
<tree string="Sites">
<field name="sitecode"/>
<field name="name"/>
</tree>
</field>
</record>
 <record model="ir.ui.view" id="site_form_view">
<field name="name">my.site.form</field>
<field name="model">my.site</field>
<field name="arch" type="xml">
<form string="Site">
<sheet>
<group>
<field name="sitecode"/>
<field name="name"/>
</group>
</sheet>
</form>
</field>
</record> 
<record id="my_warehouse_site_inherit" model="ir.ui.view">
<field name="name">stock.warehouse.inherit</field>
<field name="model">stock.warehouse</field>
<field name="inherit_id" ref="stock.view_warehouse"/>
<field name="arch" type="xml">
<xpath expr="//field[@name='code']" position="after">
<field name="sitecode"/>
<field name="name"/>
</xpath>
</field>
</record>
</data>
</openerp>
</script>

when i install it, i got error:

it's not correct to use <script type="text/javascript"> in odoo module, as you're using... you should put python code in python files (with .py extension) and xml code in xml files... also you should follow directory structure and create __odoo__.py manifiest as well.

Because someone undervoted my answer, I want to try and improve it:

If you want to add new one to many field 'others' to you model 'module.model' using code, you should create a many2one field to the table you want to link to, if that table doesn't already have it. Let's call the link table 'module.other'.

If you already have many2one field in the other table (where you want to have one2many) go to step 2.

(At database level, one2many does not exist, it is a reference to many2one field in the other table. )

Step 1:

Create many2one field in 'module.other':

- Create a new file module_other.py

- into this file write:

Old api:


from openerp.osv import fields, osv

class module_other(osv.osv):
     _inherit = 'module.other'
    _colums = {
        'model_id': fields.many2one('module.model', 'Model', required=True),
    }

New api:

from openerp import models, fields, api

class module_other(models.Model):
 _inherit = 'module.other'
 _colums = {
 'model_id': fields.Many2one('module.model', string='Model')
 }

 


Step 2:

Create one2many field in 'module.model':

- Create a new file module_model.py

- into this file write:

Old api:

from openerp.osv import fields, osv

class module_model(osv.osv):
 _inherit = 'module.model'
 _colums = {
     'others': fields.one2many('module.other', 'model_id', 'Others'),
 }

New api:

from openerp import models, fields, api
class module_other(models.Model):
 _inherit = 'module.other'
 _colums = {
     'others': fields.One2many('module.other', 'model_id', string='Others')    ,
 }

Note that in code I did add:

_inherit = 'module.other'

_inherit = 'module.model'

This line should be added only if you are adding custom field to existing model.


Step 3:

Add field to the view. In new file called module_model_view.xml write:

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record id="view_module_model_form" model="ir.ui.view">
             <field name="name">Add custom one2many</field>
             <field name="model">module.model</field>
             <field name="inherit_id" ref="module.old_view_name"/>
             <field name="arch" type="xml">
                 <field name="existing_field" position="after">
                       <field name="others" />
                </field>
             </field>
         </record>
    </data>
</openerp>

This is the case of adding the field to an existing view.
