Learn – Overriding name_get method in Odoo 8 with Example

Example of name_get method in Odoo 8:-

Here, what I want to do is, I want to view country and the country code both as name for any country.

1. This was the scenario in the beginning. Whenever I clicked Many2one field of country (which calls name_get method) it only showed the country name as display value as shown in the picture below. My goal is to see the country name + country code as display.

   

2. Now I will override the name_get method of res.country model.
   

   Code to Override name_get method in Odoo 8 –

   from openerp import models,api
   
   class res_country(models.Model):
       _inherit = 'res.country'
   
       @api.multi
       def name_get(self):
   
           res = super(res_country, self).name_get()
           data = []
           for country in self:
               display_value = ''
               display_value += country.name or ""
               display_value += ' ['
               display_value += country.code or ""
               display_value += ']'
               data.append((country.id, display_value))
           return data

   Here, I need to prepare a list of tuple wich is passed as return value to the method.

   Inside the loop of self, I need to prepare a string which I want as the display value. Here i concatenated the name and code. i.e display_value in above code

   Then prepare a tuple. The first value in the tuple is the id of the record and the second value is the string (display) that we prepared above. Append all the tuples in a list and return.

3. Now after restarting the server when I click on the Many2one field of country, country name + code is seen in the view as shown in the picture below,
