how to get POST data in django 1.3


Hey, I am following this tutorial to learn to make a wiki page with Django. However, it is made in django 0.96 and I use Django 1.3 so there are some things that are different. Some I already fixed myself, however this one I can't seem to make it work.

I made a form that submits data to a view. This is the form:

<form method="post" action"/wikicamp/{{page_name}}/save/">{% csrf_token %}
    <textarea name="content" rows="20" cols="60">{{content}}</textarea><br>
    <input type="submit" value="Save Page"/>

and the /wikicamp/{{page_name}}/save/ url redirects to the save_page view:

from django.http import HttpResponseRedirect
from django.core.context_processors import csrf

def save_page(request, page_name):
    c = {}
    content = c.POST["content"]
        page = Page.objects.get(pk=page_name)
        page.content = content
    except Page.DoesNotExist:
        page = Page(name=page_name, content=content)
    return HttpResponseRedirect("wikicamp/" + page_name + "/")

However the problem is that I get this error:


Reason given for failure:

    CSRF token missing or incorrect.

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django's CSRF mechanism has not been used correctly. For POST forms, you need to ensure:

    The view function uses RequestContext for the template, instead of Context.
    In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.
    If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.

You're seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.

You can customize this page using the CSRF_FAILURE_VIEW setting.

So I read through some of the documentation, like I tried to do that however and it still gave the same error.

So: Anyone an idea how to handle form post data well with Django 1.3?

I think it has something to do with: The view function uses RequestContext for the template, instead of Context. but i don't now what it is.

btw, in my terminal which shows the http request of the localhost it says this: A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually caused by not using RequestContext.

You will need the {% csrf_token %} template tag in between your tags as well as including


in your MIDDLEWARE_CLASSES in the applications

Adding some example post data handling:

This is an example of one of the times I am using POST data in a view. I will generally rely on the form class to do verification via the cleaned_data array.

if request.method == 'POST':
        form = ForgotPassword(data=request.POST)
        if form.is_valid():
                new_user = backend.forgot_password(request, **form.cleaned_data)
            except IntegrityError:
                context = {'form':form}
                form._errors[''] = ErrorList(['It appears you have already requested a password reset, please \
                check ' + request.POST['email2'] + ' for the reset link.'])
                return render_template(request,'passwordReset/forgot_password.html',context)
            if success_url is None:
                to, args, kwargs = backend.post_forgot_password(request, new_user)
                return redirect(to, *args, **kwargs)
                return redirect(success_url)
