I need to add sql constraint so that it prevent the duplication in customer name.The sql constraint cannot be added to the existing module as it cannot be edited.So a new module has to be created.How to create this module and how to inherit the features in my new module and add the new features. ?
You can add the following code in your module to apply unique constraint for Customer :
class res_partner(osv.osv): _inherit = 'res.partner' _sql_constraints = [ ('name_uniq', 'unique(name)', 'Customer Name must be unique!'), ]
Before installing the module, make sure that existing customers don't have duplicate names. If exists, rename those Customers, else constraints will not be applied.
