i add quote on URLField :

class MyAdmin(admin.ModelAdmin): formfield_overrides = { 'URLField': {'widget': URLFieldWidget}, }

Then no error now, but not any URLFieldWidget on my admin url field...

??

Ok i succeed :

Here the solution for django 1.1.1

from django.contrib import admin from django.db import models from django.utils.safestring import mark_safe from myapp.models import MyModel

And all works well
