Including a querystring in a django.core.urlresolvers reverse() call

Question

I'm trying to reverse a named URL and include a querystring in it. Basically, I've modified the login function, and I want to send ?next= in it.

Here's what I'm doing now: reverse(name) + "?next=" + reverse(redirect)

Here's what I'd like to do: reverse(name, kwargs = { 'next':reverse(redirect) } )

My URL for the login page (just as an example) looks like this:

url(r'^login/', custom_login, name = 'login'),

So how do I modify this whole thing (or call it) to include the next without having to concatenate it? It feels like an iffy solution at best.

Answer 1

You can't capture GET parameters in the url confs, so your method is correct.

I generally prefer string formatting but it's the same thing.
"%s?next=%s" % (reverse(name), reverse(redirect))

http://docs.djangoproject.com/en/dev/topics/http/urls/#what-the-urlconf-searches-against

The URLconf searches against the requested URL, as a normal Python string. This does not include GET or POST parameters, or the domain name.

Answer 2

I just made my own utility function like the one asked in the question:

from django.utils.http import urlencode  def my_reverse(viewname, kwargs=None, query_kwargs=None):     """     Custom reverse to add a query string after the url     Example usage:     url = my_reverse('my_test_url', kwargs={'pk': object.id}, query_kwargs={'next': reverse('home')})     """     url = reverse(viewname, kwargs=kwargs)      if query_kwargs:         return f'{url}?{urlencode(query_kwargs)}'      return url
