View not showing when using modelform - django

Question

I'm trying to display a form, using a model form in django. Everything looks like it's setup properly, and I'm not getting any error. Simply, the form is not showing, although the url is updated...
views.py
from rulz.models import Rulz
class rules_create(CreateView):
model = Rulz
fields=['title', 'content']
models.py
from django.db import models
from django.contrib.auth.models import User
from django.urls import reverse
class Rulz(models.Model):
title = models.CharField(max_length=255)
content = models.TextField()
country = models.CharField(max_length=255,default='France')
city = models.CharField(max_length=255,default='Paris')
player_num = models.IntegerField(default=2)
complexity = models.IntegerField(default=1)
created_on = models.DateTimeField(auto_now_add=True)
author = models.ForeignKey(User,on_delete=models.CASCADE,default=1)
def get_absolute_url(self):
return reverse('rulz:rulz_detail',kwargs={'pk':self.pk})
urls.py (in the app)
app_name = 'rulz'
urlpatterns = [
#/rulz/
url(r'^', views.rules_index.as_view(), name='rulz_index'),
url(r'^index/$', views.rules_index.as_view(), name='rulz_index'),
# /rulz/details
url(r'^(?P<pk>[0-9]+)/$',views.rules_detail.as_view(),name='rulz_detail'),
#rulz/create
url(r'^create/',views.rules_create.as_view(),name='rulz_create'),
]
urls.py (root folder)
...
url(r'^rules/',include('rulz.urls')),
...
app/templates/app/rulz_form.html
{% extends 'rulz/Rulz_base.html' %}
{% block body %}
{% load staticfiles %}
{% include 'rulz/form-template.html' %}
{% endblock %}
app/templates/app/form-template.html
{% for field in form %}
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<span class="text-danger small">{{ field.errors }}</span>
</div>
<div class="validate-input m-b-26" >
<label class="label-input100">{{ field.label_tag }}</label>
<div class="input100">{{ field }}</div>
<div class="col-sm-offset-2 col-sm-10">
<span class="text-danger small">{{ field.help_text }}</span>
</div>
</div>
</div>
and finally the button with the link in my page to access the form :
Go create Rule
I really don't know what I am missing. When I click this button, the url is uploaded to http://127.0.0.1:8000/rules/create/ but the displayed page is exactly the same.
Any clue ?
Thanks

Answer 1

You need to terminate your index regex. At the moment it matches every string the has a start, which of course means every string. Use the $:
url(r'^$', views.rules_index.as_view(), ...
(As an aside, you should avoid having two patterns for the same view.)

In the documentation you can find the list of the attributes needed to correctly rendering your form using CreateView.
So, you need to modify your class based view to look like at least this example:
from rulz.models import Rulz
class rules_create(CreateView):
form_class = YOUR_FORM # The form that will be used with this class
model = Rulz
fields=['title', 'content']
success_url = 'YOUR_SUCCESS_URL' # If success redirect to this URL
