Question

My application uses Django’s login view from django.contrib.auth.views.login, with a custom template I made.

I’d like to pass my template an additional argument which will change the login page in a few ways. Actually, I’m trying to show a different login page based on the URL.

How can I pass additional arguments to the login’s view & to my custom template?

Answer 1

The source shows there is only one place that would influence the template context.

def login(request, template_name='registration/login.html',
          redirect_field_name=REDIRECT_FIELD_NAME,
          authentication_form=AuthenticationForm): # here

So your only option is to hitch a ride on AuthenticationForm or write your own login view (which, by the way, is very simple if you look at the code).

from django.contrib.auth.forms import AuthenticationForm

AuthenticationForm.my_extra_data = 'foobar'

(r'^accounts/login/$', 'django.contrib.auth.views.login', \ 
     {'template_name': 'myapp/login.html', \
      'authentication_form': AuthenticationForm }),

Template

{{ form.my_extra_data }}
