Django login_required不重定向

Question

I'm new to Django, so bear with me. I am trying to make a page that the user has to be logged in to visit using @login_required , but it doesn't seem to be doing anything whatsoever. (No error, no redirect, nothing.)

Here is what I have relating to this issue:

project settings.py

LOGIN_URL = '/login'

app views.py

from django.contrib.auth.decorators import login_required

@login_required
def index(request):
    context = RequestContext(request)
    return render_to_response('evaluation/index.html')

project urls.py

url(r'^login/$', 'django.contrib.auth.views.login')

I don't know if this is related either, but on this page where I want login to be required, I have it set up that it should show the username if logged in, but it doesn't do that, either, even after I seem to successfully log in and am redirected by my login page:

{% if user.is_authenticated %}
<h1>Hello {{ user.username }}</h1>
{% else %}
<h1>Hello world</h1>
{% endif %}

I have looked at the documentation for django.contrib.auth, but it hasn't been useful. Does next have anything to do with this problem? I still can't figure out what on earth that is or does, despite my googling. (If anyone has suggestions for good resources related to this, that would also be appreciated.)

Answer 1

You're not passing your context to the template in index , so it knows nothing about the user variable. You should do:

return render_to_response('evaluation/index.html', context)

or even better, drop the context variable altogether and just do

return render(request, 'evaluation/index.html')

(since render, unlike render_to_response, uses RequestContext by default).
