Hello,
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):
_inherit='product.public.category'
def _nb_product_fnc(self, cr, uid, ids, name, arg, context=None):
category=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
_columns={
'nb_product': fields.function(_nb_product_fnc, type="integer", string="Total product for this categories"),
}
