AccessError when users edit many2one field in custom module

Question

I created a custom module to add some fields into Partner data. Everything seems to work well but no admin users can't edit many2one fields. It shows the following message (as if any permissions configurations were wrong with that model):

After doing what you asked, this is what happens:

This is the error I get:

Exception: Fall\xf3 el m\xf3dulo cargando cant_neg_dir: no se pudo procesar el archivo cant_neg_dir/security/ir.model.access.csv: Line 1 : No se han encontrado registros coincidentes para id. externo 'group_name_test_user' en el campo 'Object'

And this is what I have in my files:

ir.model.access.csv

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_sector_user,sector.user,group_name_test_user,base.group_user,1,1,1,1

    _columns = {

class sector(models.Model):

    _rec_name= "sector_name"
    _columns = {

    _name = "municipio"
    _rec_name= "municipio_name"
    _columns = {

}

Again, thanks for your help.

Answer 1

You need to give security access right to new object.

We can do it via code. For example:

access_sector,sector.user,model_sector,base.group_user,1,1,1,1

For more details security/ir.model.access.csv and Odoo Security Documentation.

EDIT

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_sector,sector.user,model_sector,base.group_user,1,1,1,1

EDIT

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_sector_user,sector.user,your_module_name.group_name_test_user,base.group_user,1,1,1,1

And make sure openerp.py file will be look like following position file name

cant_dir_security.xml
ir.model.access.csv
