On account.voucher I added a one2many field like this : 

'bls_to_pay': fields.one2many('stock.picking.out','bl_id','BLS to pay'),

I added a many2one field on both stock.picking.out and stock.picking like this : 

'bl_id': fields.many2one('account.voucher','BLs to pay'),

On stock.picking.out, I have a field "num_bl", that I added by inheritance. and so as to add a field into stock.picking.out, you have also to add it on stock.picking as well, and that's what I did.

The probleme is when I try to display the field on the one2many tree, it prints on log the following error : 

Can't find field num_bl on the following view parts composing the view of object model account.voucher, either you wrongly customzed the view, or some modules bringing those views are not compatible with your current data model.

All of this knowing that I tried with other fields of stock.picking, wich have been created initially with the model, and not added by inheritance and it worked, the problem is just with the field "num_bl", wich have been added by inheritance ( custome  module ).

Here is an example, working for date field of stock.picking : http://prntscr.com/5euiix

Why this behaviour occurs ?

The error message indicates that you tried to create a view for account.voucher model that contains num_bl field. As you have stated this field is in the stock.picking. Maybe you can post your view here so that it can be analyzed further.

Ivan

Also you might want to post the definition of num_bl field as well complete with the class.

Hi Ivan, 

Here after the object inheritance made, so as to add the field 'num_bl' :

Module name : add_num_bl

Path : add_num_bl/stock.py

from openerp.osv import fields, orm

class StockPicking(orm.Model):

    _inherit = 'stock.picking'
    _name = 'stock.picking'
    _columns = {
        'num_bl': fields.char('Numero BL',size=64),
        'bl_id': many2one('account.voucher','BLs to Pay', ondelete='cascade'),

    }
    _sql_constraints = [
        ('bl_uniq','unique(num_bl)','Numero BL est unique, veuillez verifier. !')]


class StockPickingOut(orm.Model):

    _inherit = 'stock.picking.out'
    _name = 'stock.picking.out'
    _columns = {
        'num_bl': fields.char('Numero BL',size=64),

        'bl_id': many2one('account.voucher','BLs to Pay', ondelete='cascade'),

    }


Stock_view.xml :

 

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record id="view_bl_custom_form" model="ir.ui.view">
            <field name="name">picking.custom.form</field>
            <field name="model">stock.picking.out</field>
            <field name="inherit_id" ref="stock.view_picking_out_form"/>
            <field name="arch" type="xml">
                <xpath expr="//form/sheet/group/group/field[@name='origin']" position="after">
                    <field name="num_bl"/>
                </xpath>
        </field>
        </record>
        <record id="view_bl_custom_tree" model="ir.ui.view">
            <field name="name">picking.custom.tree</field>
            <field name="model">stock.picking.out</field>
            <field name="inherit_id" ref="stock.view_picking_out_tree"/>
            <field name="arch" type="xml">
                <xpath expr="//tree/field[@name='partner_id']" position="after">
                    <field name="num_bl"/>
                </xpath>
            </field>
        </record>

    </data>
</openerp>

I created another custom module to :


1. Customize voucher_sales_purchase_view.xml, by creating another view, and ignoring the old one, I didn't pass by inheritance because I needed to redefine the view ( a lot of radical changes ).
2. Add the one2many field : "bls_to_pay".

Module name : account_payment_bl

Path : account_payment_bl/account_voucher.py

from openerp.osv import fields, orm

class AccountVoucher(orm.Model):

    _inherit = 'account.voucher'
    _name = 'account.voucher'
    _columns = {
        'bls_to_pay': fields.one2many('stock.picking.out','bl_id','BLS to pay'),
    }

voucher_sales_purchase_view.xml :

I just posted the view that interests us the most in this question.

Have you tried setting the model to stock.picking instead of stock.picking.out when defining the bls_to_pay field? So: 'bls_to_pay': fields.one2many('stock.picking','bl_id','BLS to pay'). Inheritance for stock.picking is particularly unique as all 3 models (stock.picking, stock.picking.in, stock.picking.out) share the same table. The only one truly linked to the table is stock.picking, which is the base model.

Yes i've tried this, same result ...

And when I add the fields direclty on the objects : stock.picking and stock.picking.out, without passing by inheritance, it works, and everything looks fine ...

Ivan

And module account_payment_bl depends on module add_num_bl?

TEIMI Yassine

No I didn't make any dependency between them, account_payment_bl depends on account_voucher, because it extends it.

Ivan

You should because account_payment_bl uses 'bl_id' field of stock.picking which is created by add_num_bl. So, in a way account_payment_bl can only work if add_num_bl is there and installed. Dependency also affects how the sequence inheritance will be called.
