Question: I am making an app of login form but when I am running my app and click on login button the following error will occur 

**Forbidden (403)
CSRF verification failed. Request aborted.**

the code of view.py is as:

```
from django.template import  loader
from django.shortcuts import render_to_response
from registration.models import Registration
from django.http import HttpResponse
from django.template import RequestContext
from django.shortcuts import redirect

def view_login(request,registration_id):
   t = loader.get_template('registration/login.html') 
   try:
         registration=Registration.objects.get(pk=registration_id)
   except Registration.DoesNotExist:
         return render_to_response("login.html",{"registration_id":registration_id})

def home(request,registration_id):
    if request.method == "POST":
      username = request.POST.get('user_name')
      password = request.POST.get('password')
      user = authenticate(username=username, password=password)
      if user is not None:
        if user.is_active:
          login(request, user)
        # success
          return render('registration/main_page.html',{'registration_id':registration_id},context_instance=RequestContext(user))
        else:
         #user was not active
           return redirect('q/',context_instance=RequestContext(user))
      else:
        # not a valid user
           return redirect('q/',context_instance=RequestContext(user))
    else:
       # URL was accessed directly
           return redirect('q/',context_instance=RequestContext(user))

```

Answer: 
I encountered this problem while using the book "The Definitive Guide to Django" wherein version 1.1 is used. The book does not address the need for csrf\_token verification that is mandated in later versions.

To fix this issue, add:

```
from django.template import RequestContext

```

to the views.py file and this added argument for the render\_to\_response function:

```
context_instance = RequestContext(request)

```

Be sure to add `{% csrf_token %}` within the `<form>` tags in the template
Just comment 
`'django.middleware.csrf.CsrfViewMiddleware'`

in your **settings.py**, which works for me:

```
//settings.py
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
#'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

```

**THIS MAY HAVE SECURITY FLAWS UNLESS YOU SOMEHOW MANAGE CSRF IN ANOTHER WAY, AND IS NOT RECOMMENDED, AS YOU WILL BE SUSCEPTIABLE TO CSRF ATTACKS**
