Django redirect using reverse() to a URL that relies on query strings

Question

I\'m writing a django application with a URL like \'http://localhost/entity/id/?overlay=other_id\'. Where id is the primary key of the particular entity and overlay is an o

You shouldn't generate the url string yourself. Given your urls.py you can use reverse like so:

from django.core.urlresolvers import reverse
print reverse('view_function_name', kwargs={"id":"id_value", "overlay_id": "overlay_id_value"})

# or to pass view function arguments as an array:
print reverse('view_function_name', args=("id_value","overlay_id_value",))

If you use named url patterns, which are great for disconnecting your view functions from url identifiers:

# urls.py
...
(r'^update/(?P.+)/(?P.+)/$', 'update', name="update_foo"),
...

Use reverse like so:

print reverse("update_foo", kwargs={"id":"id_value", "overlay_id": "overlay_id_value"})
