Unique values but how to prevent with spelling mistakes - Odoo

Question

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'),
> 
> ]

Answer 1

I believe the _sql_constraints is not case sensitive so Bakery should be considered the same as bakery , therefore the record can't be created if it's the same attribute with different cases. Right?

Answer 2

Alternative, you can change it to selection field. Instead of User enter value, let's manager creates that values and User will select it from the list.

Answer 3

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
