Hi, another question about inheritance.

I have a model that inherits from res.partner. This means that my model will have it's own fields plus the parent ones, comprising the fields added from some custom modules that modify the res.partner  (or not?). If I look at my model table in the database I can see all the fields (the ones from the base model and the ones added by custom modules, so it seems I have inherited them all, seems).

The problem is that when in a View I try to reference one field that is not in the base model since it has been added by a custom module that modifies the base model (i.e. adds fields to that table) I got an error saying the field doesn't exist (but actually the column is present in the database table for my model, so it should be there)! There is something I do not understand. Shall I inherit from the model in the custom module that modifies res.partner? How, since the model name is always res.partner?

Let's see the code of the custom module that modifies res.partner

class res_partner(osv.osv):

_inherit = "res.partner"

_columns = {

'partner_latitude': fields.float('Geo Latitude', digits=(16, 5)),

'partner_longitude': fields.float('Geo Longitude', digits=(16, 5)),

'date_localization': fields.date('Geo Localization Date'),

}

In the database table for my model I can see a column for each of these fields, but if in my view I try to add one of those, e.g. partner_longitude, I got an error saying the field does not exists. Why? I miss something but I cannot figure out what.

Thanks.

PS: here it is the code for the class:

class genial_2015(osv.osv):

"""Db test genial_2015 """

_name = 'genial.2015'

_inherit = 'res.partner'

_columns = {

'cod_cat': fields.char ( 'Categoria', size=2, required = True),

'titolo': fields.char ('Titolo', size = 31),

'name': fields.char ('Azienda', size = 31, required = True, select = 2),

'street': fields.char ('Indirizzo', size = 31, required = True, select = 1),

'street2': fields.char ('Indirizzo2', size = 31),

'zip': fields.char ('CAP', size = 5, required = True, select = 1),

'city': fields.char('Località', size = 22, required = True, select = 1),

'provin': fields.char('Provincia', size = 2, required = True, select = 1),

'phone': fields.char ('Telefono', size = 15, select = 1),

'tipocli': fields.char('Tipo Cliente', size = 1, rquired = True, select = 1),

'statocli': fields.char('Stato Cliente', size = 1, required = True, select = 1),

'annull': fields.boolean ('Annullato', select = 1),

}

"""Assegna i valori di default ai campi"""

_defaults = {

'annull' : 0, 'statocli' : 'A', 'tipocli' : 'C', 'cod_cat' : 'OD',

}

Here the part of the view (that is mainly a copy of res.partner) in which I insert my custom field:

<xpath expr="//field[@name='website']" position="after">

<field name="titolo" placeholder="SPETTABILE STUDIO DENTISTICO" />

</xpath>

If I try to insert one of the (new) inherited field <field name="partner_longitude" placeholder="0.00" />, I get an error.

Thanks.

Hi Axel, here you are the code for the class:

class genial_2015(osv.osv):

"""Db test genial_2015 """

_name = 'genial.2015'

_inherit = 'res.partner'

_columns = {

'cod_cat': fields.char ( 'Categoria', size=2, required = True),

'titolo': fields.char ('Titolo', size = 31),

'name': fields.char ('Azienda', size = 31, required = True, select = 2),

'street': fields.char ('Indirizzo', size = 31, required = True, select = 1),

'street2': fields.char ('Indirizzo2', size = 31),

'zip': fields.char ('CAP', size = 5, required = True, select = 1),

'city': fields.char('Località', size = 22, required = True, select = 1),

'provin': fields.char('Provincia', size = 2, required = True, select = 1),

'phone': fields.char ('Telefono', size = 15, select = 1),

'tipocli': fields.char('Tipo Cliente', size = 1, rquired = True, select = 1),

'statocli': fields.char('Stato Cliente', size = 1, required = True, select = 1),

'annull': fields.boolean ('Annullato', select = 1),

}

"""Assegna i valori di default ai campi"""

_defaults = {

'annull' : 0, 'statocli' : 'A', 'tipocli' : 'C', 'cod_cat' : 'OD',

}

Here the part of the view (that is mainly a copy of res.partner) in which I insert my custom field:

<xpath expr="//field[@name='website']" position="after">

<field name="titolo" placeholder="SPETTABILE STUDIO DENTISTICO" />

</xpath>

If I try to insert one of the (new) inherited field <field name="partner_longitude"  placeholder="0.00" />, I get an error.

Thanks.

Post all the view def so we could know what you are doing wrong

Hi Axel, thank you very much for your help. Here it is the code, for brevity I will not paste it all, but actually it's just a copy and paste of the standard res.partner view (otherwise the design was gone)., with the addiction of my custom field: genial.2015.form genial.2015 primary ... <xpath expr="//field[@name='website']" position="after"> ... The error is always the same: the new field is not recognized. In my opinion it is not a matter of view, but of the model that, anyway, seems correct (I have that field in my table!!!!).

Sorry but the code is missing in the comment. You can see it here: http://pastebin.com/VSM5KBHR

When you define an _inherit and no _name, you are inheriting by extension the other model, meaning that you are not creating a new model, you just are changing the original one, res.partner, so your view need to be defined over the res.partner model, and after the module that contains the extension is updated you will be able to use and see the new fields in the custom view of the res.partner model.

===================================================================================================

According to your example, seems that you are extending a view of res.partner to use it as your own view for your genial_2015 model. For that you need to define to your view the field mode with the value primary, Like:

<record id="genial2015_view" model="ir.ui.view">
...
<field name="mode">primary</field>
<field name="arch">
...
</field>
</record>

That allow you to inherit the view of the other model as a prototype for your view of your model

That's what I thought, and so I did. I installed the custom module Geo Localize that modifies res.partner and adds the three fields than I inherited res.partner in my model that has a name, so it doesn't extend res.partner but has its own table. But it doesn't work. The new fields are in my table (I it is supposed to be) but I cannot reference them in my View. If I try I get an error!

show us the code and the view

I tried but it doesn't work. I get the same error: ParseError: "ValidateError Field(s) `arch` failed against a constraint: Invalid view definition Error details: Field `partner_longitude` does not exist I modified the view accordingly to your suggestion adding primary but the field isn't recognized.
