I installed a bespoke module in my Odoo V11who works perfectly with empty database. Then I import database of my old Odoo 8 with csv files.

But after it is like Odoo don't find the new models and the fields I add.

For exemple I add app_product_key in the model res_partner:

But when I tried to acces my database with xml-rpc with this field as identification I get:

2018-07-26 10:15:51,679 22263 ERROR probespoke odoo.http: Invalid field 'app_product_key' in leaf "<osv.ExtendedLeaf: ('app_product_key', '=', 'fonapp2016') on res_partner (ctx: )>"

ValueError: Invalid field 'app_product_key' in leaf "<osv.ExtendedLeaf: ('app_product_key', '=', 'fonapp2016') on res_partner (ctx: )>"

And I got same error for other fields I add in other module.

Why Odoo consider this fields has no-existent?
