code = fields.Char(string='Reference', index=True, tracking=True)
_sql_constraints = [('unique_code', 'unique(code)', 'La référence doit être unique !')
Thanks
Hi,
SQL constrains will work for new and existing db. In existing database, you may have some records which already violates this constrains and thus it is not working.
So manually fix the existing violated records and apply the SQL constrains. In case if you can't fix existing records, then you have to use api.constrains for new records.
Thanks
Hi,
finally it work in my existing db, So the solution is to search for any duplicating data for the field that we want to applied to sql_constraint
remove all duplicate data
remove compiled file "model.pyc"
restart odoo-service
Refresh your browser
and it will work fine
This is Help for You,
Syntax,
_sql_constraints = [('<sql_constraints_id>', 'unique(<Your field name>)', '<Custom Message>')]
Example,
_sql_constraints = [('user_unique', 'unique(userid)', 'User already exists.')]
