How to solve AttributeError 'myField' in a simple module?

on 5/14/13, 4:33 PM 4,252 views

I have just made an addon that adds a field to the stock.picking.out form.

Here is my code :

from osv import fields,osv
class stock_picking_out2(osv.osv):
    _name = "stock.picking.out"
    _inherit = "stock.picking.out"

    _columns = {
        'statut_id2': fields.many2one('sale.statut', 'Statut', required=True),

<record id="view_livraison_move_picking2_form" model="ir.ui.view">
   <field name="name">stock.picking.out.form.inherit</field>
   <field name="model">stock.picking.out</field>
   <field eval="1" name="priority"/>
   <field name="inherit_id" ref="stock.view_picking_out_form" />
   <field name="arch" type="xml">                
       <field name="stock_journal_id" position="replace" >
          <field name="statut_id2"/>

Everything works perfectly on my local server, but when I install the addon on a remote server I have different errors :

  • I can't edit the field with the form : when I edit, the changes are not saved.

  • I got this error when I try to edit a field in another form like "SALE ORDER" form :

(The error occurs for any types of fields, I tried to replace by Integer, char, etc... So I don't think that I comes from the relational field !)

I have also tried to change stock.picking.out by stock.picking in the inheritance and it worked, but I can't modify the field I want in the XML code...

The module is very simple but I can't see where my error come from... Do you have any idea to solve it?

Were you able to fix this problem Matt? I am struggling with this one as well.

Try the following:

  1. append openerp. befre osv like this from openerp.osv import fields,osv
  2. remove this line _name = "stock.picking.out"
  3. in your many2one field, change the object from 'sale.statut' to 'stock.picking.out'
  4. restart openERP server & reinstall your module

Note: Your XML code should be surrounded with two tags <openerp><data>YOUR XML CODE</data></openerp>, just to remind you.. :)

Thanks for you answer, but it didn't solve the problem. I have done parts 1, 2 and 4. I don't understand why you're telling me to change the object in part 3, I need to insert a field of type 'sale.statut' in the stock.picking.out form, so I think I'm doing it in the good way. Is it that you didn't understand what I wanted to do or am I doing it wrong?

(And I already had the <openerp><data> tags, I just didn't want to put the useless parts of the code in my question.)

Hmm, So i believe that you have defined this object somewhere in your module, something like _name = 'sale.statut'? (because, i cant see it in your posted code)

Yes it is defined in another module, and the problem doesn't come from that module because I used the same kind of field in another object without any problem... I got the same problem if I replace 'statut_id2': fields.many2one('sale.statut', 'Statut', required=True), by 'test': fields.integer('Test'),

u can create the same field in "stock.picking" and "stock.picking.out", then u can inherit the form/tree view stock.picking.out and then you will be able to add the fields in this.
