Prevent Duplication of Customer Name

I had the issue of duplicated customer names in Openerp..I'm trying to create a module for OpenERP 7 that prevents double partner records. For instance if I create a contact with the name: "Ajay."; I want an error prompt to come up when I make another contact with the exact same name, and saving is prevented.

After reading up on the web and the help section here, the best way to accomplish this seemed to use an sql constraint. In some of the topics I've read it was recommended to create a new module just for this.

I have created a module, which I named Customer_validation and I am able to install it on my database on the server. However, my code does not seem to be working - I can still enter double partner names without validation.

This is my first module, so I may have very well made a mistake. Is there something that is missing from my code, or if I forgot something in my module?

Folder name: "Customer_validation" Folder contains: 3 files

     import crm

  "name" : "customer_validation",
  "version" : "0.1",
  "description" : """
  Adds partner validation
   "author" : "Sneha",
  "depends" : ['crm'],
  "category" : "Generic Modules/Base",
  "init_xml" : [],
  "demo_xml" : [],
  "active": False,
  "installable": True

from osv import fields, osv

class res_partner(osv.osv): 
  _inherit = 'res.partner' 
  _sql_constraints = [ 
  ('name', 'UNIQUE (name)', 'The name of the partner must be unique !')

Hi, Change this in your files...

     import Customer_validation.py

  "depends" : ['base','crm'],

I changed and upgraded the module.But the result is still the same.No validation is working.

Change the following :

  1. import Customer_validation instead of import crm
  2. "depends" : ['base'],

I tried but still the same.validation is not working.

check your customers and partners as well. There may be possibility of existing records with same names.

I tried by removing the filters and thoroughly checked for duplicated records and removed/edited those which were found.then the module was upgraded and tried adding an already existing name.Still no validation is working for the name entered.
