I can use _sql_constraints as mentioned below to prevent duplicates but when user enter like:
Bakery
bakery
bakry
etc...
how i can prevent user to NOT enter this type of value?
> _sql_constraints = [
>
> ('categoryname_unique',
>
> 'unique(name)',
>
> 'each category should be unique'),
>
> ]
at least i can avoid duplication with same spelling but in either case (case insensitive) using below code (thanks to odoo forum - @Neha Sharma-Kanak)
@api.constrains('name')
def _check_unique_brand(self):
brand_ids = self.search([]) - self
value = [x.name.lower() for x in brand_ids]
if self.name and self.name.lower() in value:
raise ValidationError(_('The Brand Name is already Exist'))
return True
