Re: Charfield, limiting acceptable characters

Ok, solved the problem. Thanks Lukasz and thanks to all...

from django.core.validators import RegexValidator

import re

namespace_regex = re.compile(r'^[a-z\-]+$')

alias = models.CharField( max_length = 100, unique = True, validators=[RegexValidator(regex=namespace_regex)] )

Maybe RegexValidator can solve this problem. But i couldnt manage to use it:

from django.core.validators import RegexValidator

alias = models.CharField( max_length = 100, unique = True, validators=[RegexValidator('[a-z]')] )

Yes, i know overriding field cleand method, but i couldnt get a start point for character match code.

It was possible in the past with validator_list. Like:

 regex = r'^[A-z][\w-]{2,31}$'

 name = models.CharField(max_length=32, unique=True , validator_list=[validators.MatchesRegularExpression(regex)] )

But with what code to override the clean method? Is there any sample or built in function for this purpose?

If your field is named name, then you add a function to your form called clean_name and put whatever you want in it.
