hello, can you put some lines of the code ...

Qutechs, Ahmed M.Elmubarak

is the sale.order model inherited or customized, if customized, if it contains m2o field called 'order_line' from 'hotel.sale.line'?

Krishna
Penulis

yaah..I have added m2o field in sale.order model

Krishna
Penulis

code is....'order_line': fields.one2many('sale.order.line', 'order_id', 'Order Lines', readonly=True, states={'draft': [('readonly', False)], 'sent': [('readonly', False)]}), 'sale_line':fields.many2one('hotel.sale.line','order_lines'),

in .py file

class hotel_sale_line(osv.osv):
    _name = 'hotel.sale.line'
    _description = "Sale Line"
    _columns ={          
       'folio_id':fields.many2one('hotel.folio'),
        'order_lines':fields.one2many('sale.order','order_line','Sales Order'),
}

and in .xml file---

<separator string="Sale Order Lines" colspan="4"/> 
<field name="sale_lines" colspan="4" nolabel="1"> 
<form string="Sales Order">
 <separator string="Sales Order"/>
 <field name="order_lines" select="1" colspan="4" nolabel="1"/>
 </form> <tree string="Sales Order Lines" editable="bottom"> 
 <field name="order_lines"/>
 </tree>
 </field>

Simplify it!

I am not sure what you want to do, but all the concept is wrong. If you are inheriting the sales.order then you don't have to create another model, you have to add some fields to sale.order. If you are creating a new model then you can't have the order.lines because sale.order is already using that. If you want to add sale.order to your model you have to have 2 fields that relate them. a many2one and one2many, then its going to work

I am new to openerp. So, Please can you post one example for that.Thanks for your help.

Qutechs, Ahmed M.Elmubarak

@Krishna please check this like https://doc.openerp.com/v6.0/developer/2_5_Objects_Fields_Methods/field_type.html/ for one2many field, and as @Grover said please tell us what do you aim to do, is it your own customized module , or you want to inherit the sale module

Krishna
Penulis

ok..i want to add the sale order line in my custom module then what should I have to do for that?

Krishna
Penulis

using my code..i can see the sale order form from sales module..everything is working fine..but when i confirm my whole form then it gives error of such type.that i have shown you..So where is problem i can't undestand???

Abhishek H Menon

Please don't put direct link to the existing models in openerp, it is a bad practise. Instead of that inherit an existing class here it is sale.order, and add your required fields you want to display additionally and along with that, give a many2one id inorder to create an inverse relationship with the former model that is here it is hotel.sale.line. then onlye you can create a one2many relationship. But at first you have to define the inherited hotel.sale.line after that define sale.order in your custom module, Thanks
