I need to make the VAT (TIN) field from res.partner available in account.invoice, so I can add it to the Invoice Tree View. How can I achieve this?

You have to customize one small module to make it visible to invoice, for more info contact@tidyway.in

I know how to create a module, I just need to know what to inherit exactly...in order to pass the field data from one model to another

Hi,

You can inherit account.invoice object and add a functional field.

Try like this:

in .py file:

from openerp.osv import fields, osv
class account_invoice(osv.osv):
 
    _inherit = "account.invoice"
    
    def _get_vat_num(self, cr, uid, ids,field_name, args, context=None):
        
        partner_pool = self.pool.get('res.partner')
        invoice_pool = self.pool.get('account.invoice')
        res = {}
        for inv_id in self.browse(cr, uid, ids, context=context):
            invoice = invoice_pool.browse(cr,uid, inv_id.id, context=None)
            partner = partner_pool.browse(cr, uid, invoice.partner_id.id, context=None)
            res[inv_id.id] = partner.vat
        
        return res 
    
    _columns = {
                
                'inv_vat': fields.function(_get_vat_num, string="VAT", type='char', method=True)  
                 }


in .xml file:

<openerp>
    <data>
        <record id="invoice_form_inherit" model="ir.ui.view">
    		<field name="name">invoice.form.inherit</field>
    		<field name="model">account.invoice</field>
    		<field name="inherit_id" ref="account.invoice_form"/>
    		<field name="arch" type="xml">
    		    <field name="partner_id" position="after">
    		    	
                                    <field name="inv_vat"/>
    		    </field>
    		</field>
		</record>
            
    </data>
</openerp>

Thanks Akhil! and sorry for my late response, I was busy and hadn't been able to try it till now. That's exactly what I was looking for, I just changed the view code to tree instead of form, and it worked. Thanks again for the detailed response.

Hello,

May be this will help full to you.

Inherit account.account.

Add one functional field in account.account which fetch value from res.partner because partner_id is already present in account.account.

Thanks.

Function fields are deprecated in api v10, now should be

inv_vat = fields.Char(string="VAT", compute="_get_vat_num")
