[jnoruzi]

Hi.
I'm trying to use django-imperavi beside djang-newsletter project on python 3.7 and Django 3.0.6 but i faced a lot of errors.
1- first : you didn't used a dot (.) in "from widget import ImperaviWidget"
2- old : from django.forms.util , correct : django.forms.utils
3- old : from django.utils.encoding import force_unicode, correct : .... import force_text
4- old : from django.core.urlresolvers import reverse, correct : from django.urls import reverse
5- didn't used dot(.) in "from views import . . ."
