How to add max_length to allauth username

Question

I\'m using Django allauth as my user account framework for my django site. The docs show there is an ACCOUNT_USERNAME_MIN_LENGTH however there is no ACCOUNT_USERNAME_MAX_L

Answer 1

Not sure if this is the best way but it works.

After extending the SignupForm, Completely changed the username field with a new one that has the max_length parameter.

from django import forms
from django.utils.translation import ugettext_lazy as _
from allauth.account.forms import SignupForm

class AllauthSignupForm(SignupForm):
    username = forms.CharField(label=_("Username"),
                               min_length=5,
                               max_length=20, # Change this 
                               widget=forms.TextInput(
                                   attrs={'placeholder':
                                              _('Username'),
                                          'autofocus': 'autofocus'}))
