I've some url that I want to render a template without creating a view for each one, but inside I need a form with the csrf tag, so when the user post the form I get no csrf token becouse the template have no RequestContext render on it.
How can I render templates declare in url and use csrf without creating a view for each one
My urls.py
path('path/', TemplateView.as_view(template_name='template.html')),
The error:
CSRF token missing or incorrect.
UserWarning: A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually caused by not using RequestContext.
"A {% csrf_token %} was used in a template, but the context "

I have seen a number of forums and posts but still couldn't get the handle of it. Here in django doc, it says
The CSRF middleware is activated by default in the MIDDLEWARE setting. If you override that setting, remember that 'django.middleware.csrf.CsrfViewMiddleware' should come before any view > middleware that assume that CSRF attacks have been dealt with.
If you disabled it, which is not recommended, you can use csrf_protect() on particular views you want to protect (see below).
In any template that uses a POST form, use the csrf_token tag inside the > element if the form is for an internal URL, e.g.:
form action
{% csrf_token %}
Based on that, in my html template I did simply:
<form id='frm' name='frm' method="post" action="{% url 'gettip' %}" >
{% csrf_token %}
<input type="text" name="tipid" name="tipid">
<input type="submit" value="Get Tip Value"/>
</form>
I expected the CSRF_token to create the hidden element since the middleware is already loaded. I see no element in the form and I get CSRF error.
The form is not associated with any model. I haven't used forms.py either. My current view is simply to output something:
def gettip(request):
if request.POST:
return HttpResponse('You requested a tip')
#from a weblink, i was told to add the following but it made no difference
context = {}
return render_to_response('tip.html',context, context_instance=RequestContext(request))
The error I am getting is obviously CSRF missing cos the hidden element is not there at all.
I am migrating from PHP and this is giving me a hard time. Though my form is not for login purposes, I couldn't get this one to work either for the same error. I am on django 1.10 and just want to get a positive response when form is submitted.
Don't use render_to_response, it's obsolete. Use render instead.
from django.shortcuts import render
def gettip(request):
if request.POST:
return HttpResponse('You requested a tip')
context = {}
return render(request, 'tip.html', context)
If the template containing the form is rendered by another view, you'll have to fix that view as well.
I have a login form on every page that's a popup, and it requires the csrf token.
I also have some form views that have a form that doesn't require the csrf token.
What I've found is that even if I have the {% csrf_token %} on the login form, if the view isn't wrapped with csrf_protect() it doesn't generate the token, so when the login form is submitted, it gets a csrf missing error. OTOH, if I do wrap it, then the other form on the page that doesn't need it complains about it missing though the login form works. One form submits to the current page form view, while the form submits to a separate form view.
Is it possible to get the csrf_token to generate even without the csrf_protect being used?
I saw the csrf_exempt function but it doesn't help when wrapping the view either. Is it possible to render two view functions or wrap it within the template? I'm just using a {% include login.html %}
Thanks
I am using django's template engine to render my email templates.
I have no RequestContext when rendering my email, there for I have no access to my STATIC_URL and cant use the {% url %} template tag.
How can I make it work while I am not generating the email from a view function ?
if you want to add domain/url you may get it from Site model:
message_data.update({'site': Site.objects.get_current()})
I have no idea why you think you need RequestContext for the {% url %} tag. It's a normal tag, you can use it in any template.
And STATIC_URL is just a setting: if you can't get it from the context processor, just pass it in manually into the template context: context['STATIC_URL'] = settings.STATIC_URL, or even use the {% static %} template tag.
I my recent Django-project I use mako templates.
About Cross Site Request Forgery CSRF.
In django templates there is the tag {% csrf_token %} to protect from hackers.
What about mako templates? Is there any analog of csrf_token or there is another protection mechanism???
Thanks!
I ran into the same problem just today (that's why I ended up here). I found a solution, at least, for what I wanted to do, which is pass some POST data to another view through an HTML form. Here it is:
From your first view, get a CSRF Token and add it to your (Mako) context:
from djangomako.shortcuts import render_to_response as render
from django.core.context_processors import csrf
def first_view(request):
"""This view generates a form whose action is 'second_view'."""
context = { "csrftoken": csrf(request)["csrf_token"] }
return render("path/to/yourtemplate.html", context)
yourtemplate.html's form must have a field named “csrfmiddlewaretoken” whose value is the CSRF Token, which we placed in the context as “csrftoken”. As in:
<input type="hidden" name="csrfmiddlewaretoken" value="${ csrftoken }" />
Source: Cross Site Request Forgery protection (Django 1.5 Docs)
There's some sample code at Django Snippets that looks to do this, although judging by the comments, you may need to fiddle a bit. If you have trouble, you basically want to make sure that you're duplicating the Django stock CSRF tag (click the link, start on line 87).
I am using django-threadedcomments. Everything works fine except 2 things: csrf token and user template tag.
Problem is, when user submits a comment, there is no csrf token for the form, so the form could not be validated server-side. Tried adding csrf token to the dictionaries that threaded-comments passes internal with no result; kept receiving errors (most of them telling that this-method takes only 2 arguments with 3 given). Tried to fix those methods to accept 3 arguments and just pass third one further; no success.
Did someone stumble upon the same problem in past and solved it? because this is not an acceptable solution for me:
MIDDLEWARE_CLASSES = (
#'django.middleware.csrf.CsrfViewMiddleware',
)
Second one - there is a HTML helper to get the user_id for the user who posted a comment. Is there an out of the box html helper to get the name of the user by id or would i have to write it myself?
http://code.google.com/p/django-threadedcomments/
Here is the code for the project, I cant really tell exactly which chunks of it should be posted here so I just give link to the entire project.
I am really stuck in here and any help would be welcomed.
Thanks in advance.

csrf_token is a template tag -- it shouldn't be passed as an argument somewhere.
I took a look at threadedcomments and it's based on contrib.comments with no html rendering, so it's up to you to insert the csrf_token in your template.
What does your TEMPLATE code look like that is displaying your form code?
If you have CsrfViewMiddleware enabled and you are using RequestContext in your view, you simply need to add {% csrf_token %} inside of your <form></form> tags.
As for getting the user name:
ThreadedComment is a subclasses of Comment which has a name property, or you could just access the User directly...
{% for comment in comments %
{{ comment.user.first_name }}
{{ comment.name }}
{% endfor %}
You should use {% csrf_token %} tag or #csrf_protect in a views
You can put your form in its own template and {% include %} it into your page template. As of Django 1.3, {% include %} can pass context variables to the included template. Here's what I'm using with django.contrib.comments instead of a templatetag:
...
{% include "comments/comment-form.html" with content_object=article user=request.user %}
...
{%csrf_token %} works in this included template because it's using your main view context.
