Display a calculated field in the frontend odoo

on 7/26/15, 11:02 AM 683 views


I would count the number of products in the product_template table corresponding to a category of product_public_categ table.

I can get it with a calculated field but then if I want to display the contents of this field is calculated with the Qweb frontend, he referred me an error like "2" while Evaluating

Can you explain why the Qweb does not happen to the show? Sorry for my English 

class product_category(osv.Model):


def _nb_product_fnc(self, cr, uid, ids, name, arg, context=None):


         res,id_ ={}, None

        for categ in self.browse(cr, uid, ids, context=context):

            category = categ.id

            id_ = categ.id

        cr.execute("select count(id) from product_template where categ=%s" %(category))

        rep = cr.fetchone()[0] or 0 

        if id_:

            res[id_] =rep

        return res


'nb_product': fields.function(_nb_product_fnc, type="integer", string="Total product for this categories"),
