Regular expression and empty string in Odoo

on 1/11/16, 10:35 AM 2,180 views

Hi all,

i'm testing some validation functions for the phone field to avoid others characters than numbers from 0 to 9.

    def valide_tel(self, cr, uid, ids, context=None):
        record = self.browse(cr, uid, ids)
        pattern = "^\+?[0-9]*$"
        for data in record:
            if re.match(pattern, data.phone) == None:
                return False
        return True

I tested the regex on pythex.org with success, but the problem is that when no phone number is entered, Odoo complains about ValidationError: expected string or buffer.

What can i do to have this working?

When there is no value entered in the phone field, it will take it as False, and regular expression will work on string only.

So, either you make your phone field as mandatory to the user or before implementing 'if condition' check if the value of data.phone is not False .

Hope this will help you!    


I added the condition and it works: if (data.phone != False and re.match(pattern, data.phone) == None): Thank you Pawan !
