Now i want this models as Form . For this you have to following .

Your New models.py file will be like bellow :

from django.db import models
from django.forms import ModelForm

class Publisher(models.Model):
        name=models.CharField(max_length=100)
        addess=models.CharField(max_length=100)
        city=models.CharField(max_length=10)

urlpatterns = [
        url(r'^$', index),
