Hello! Help me on how to constraint a number of characters in a fields.Char? 

and number must be minimum of 12 and maximum of 15 characters

here's my models.py

bir_id = fields.Char(size=15)

def _check_length(self, cr, uid, ids, context=None):
     for record in self.browse(cr, uid, ids):
        if record.bir_id < 12:
        return False
    return True
_constraints = [(_check_length, 'Error', ['bir_id'])]


when i enter less than 12 characters, there's no error. What do you think is the problem? 

Thank you!

Hi Nissan,

To check the length (number of characters in your string), you should use len(your_string).

Ex:

if len(record.bir_id) < 12 or len(record.bir_id) > 15:
# raise exception or return False
return False

Hope this will help you.
