Inherit form of res.partner - odoo

Question

I create a new class fleet_agent that inherits from res.partner without problems
class fleet_agent(osv.Model):
_name = 'fleet.agent'
_inherit = ['res.partner']
_columns = {
'test': fields.char('Test', help='Test'),
}
then fleet_agent_form inherits base.view_partner_form also no problem
<record id="fleet_agent_form" model="ir.ui.view">
<field name="name">fleet.agent.form</field>
<field name="model">fleet.agent</field>
<field name="inherit_id" ref="base.view_partner_form" />
<field name="arch" type="xml">
<field name="state_id" position="before">
<field name="x" />
</field>
</field>
</record>
My problem is that this form does not appear as the formatting of view_partner_form and with all fields without any order ?

Answer 1

You have created a new model 'fleet.agent' by extending the base 'res.partner'. In order to show all the fields, you need to specify the fields in xml or use the classical inheritance by removing 'fleet.agent' and add your field to the base 'res.partner'.
class fleet_agent(osv.Model):
_inherit = 'res.partner'
_columns = {
'field': fields.char('Name', help='help'),
}
In xml file:
<field name="model">fleet.agent</field>

Answer 2

class Partner(model.Model):
_inherit = 'res.partner'
test = fields.Char(string='Test', help='Test'),
}
<record id="fleet_agent_form" model="ir.ui.view">
<field name="name">partner.test</field>
<field name="model">res.partner</field>
<field name="inherit_id" ref="base.view_partner_form" />
<field name="arch" type="xml">
<field name="test" />
</field>
</record>

Answer 3

Try following,
class fleet_agent(osv.Model):
_inherit = ['res.partner']
_columns = {
'test': fields.char('Test', help='Test'),
}
<record id="fleet_agent_form" model="ir.ui.view">
<field name="name">fleet.agent.form</field>
<field name="model">res.partner</field>
<field name="inherit_id" ref="base.view_partner_form" />
<field name="arch" type="xml">
<field name="state_id" position="before">
<field name="x" />
</field>
</field>
</record>
Remove _name = 'fleet.agent' from your python code, it's create new model, and in xml when you extend any parent model you must write parent model name into the view
<field name="model">res.partner</field>
So you will get extended functionality with your base class's functionality.

Answer 4

To copy table to your moule you should use inherits keyword instead of inherit. Also you have to copy view definition of partner form of base module and change it, extending wouldn't help you in creating new table.

Update: additional information on ways os inheritance:
Update2: looks like you're on right way: there is a third way of inheritance: with inherit keyword and by specifying new _name for new model.

Answer 5

Use:
class res_partner(models.Model):
_inherit = 'res.partner'
test = fields.Char(string='test')`
Upgrade module from console:
./odoo-bin -u [module_name] -c [configuration_file
