[Django]-Django after login return to last page

✅

the login_required decorator annotates the login-url adding a next field to the GET parameters. see login_required.

e.g. if LOGIN_URL is /login it becomes /login?next=/polls/3/vote

This gets passed to your login view, where you use it

  1. To render the login page upon GET or errorneos POST in a request aware manner. Please note that you need to pass the request variables to the template rendercontext. see RequestContext and render_to_response.

    return render_to_response(
        'login.html',
        my_data_dictionary,
        context_instance=RequestContext(request)
)

  2. in the template add a line like this to the login form

    <input type="hidden" name="next" value="{{ next }}">

  3. Finally upon a succesfull POST use this value to HttpResponseRedirect, either to the value of next or to LOGIN_REDIRECT_URL if no next value is present. see HttpResponseRedirect.

    ... user was succesfully authenticated...
if request.POST["next"] is Not "":
    HttpResponseRedirect(request.POST["next"])
else:
    HttpResponseRedirect(settings.LOGIN_REDIRECT_URL)

I hope this clarifies things a little bit.

I got it to work doing the following:

def login_user(request):
    login_form = LoginForm(request.POST or None)

    if request.POST and login_form.is_valid():
        user = login_form.login(request)
        if user:
            login(request, user)
            return HttpResponseRedirect(request.POST.get('next', reverse('index')))

    return render(request, 'login.html', {'login_form': login_form, 'next': request.GET.get('next', '') })
    #return render_to_response('login.html', {'login_form': login_form, 'next': request.GET.get('next', '')}, context_instance=RequestContext(request))

also included 

<input type="hidden" name="next" value="{{ next }}">

in my login.html login_form
