Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I'm adding a Many2one field to my model as the following code:
cour_exec = fields.Many2one('cour.modl')
But when I render the field in a view appears like this
cour.modl,3 (the model name, id of the entry).
I want to show just one field on the form, the description of related to that id, I've been trying to use the options for other type of fields but i don't have the desired output.
It looks like you may need to define a "_rec_name" for your custom model. That will be used as the default display name for records of that model. You could always define a "name_get" method if you want a more custom display name.
So if the name you want to see for those records is "description" field, you would see something like this on your "cour.modl" model:
class CourModl(models.Model):
_name = 'cour.modl'
_rec_name = 'description'
description = fields.Char('Description')

By default, Odoo allows searching customers only by name and displays only the name in Many2One fields. This module enhances the Many2One search and display functionality by enabling users to search using multiple fields (Phone, Email, Mobile, etc.) and display multiple values directly inside the Partners Many2One selection.
