  1. POHow do I successfully pass a function reference to Django’s reverse() function?
    text
    copied!<p>I’ve got a brand new Django project. I’ve added one minimal view function to <code>views.py</code>, and one URL pattern to <code>urls.py</code>, passing the view by function reference instead of a string:</p> <pre><code># urls.py # ------- # coding=utf-8 from django.conf.urls.defaults import * from myapp import views urlpatterns = patterns('', url(r'^myview/$', views.myview), ) # views.py ---------- # coding=utf-8 from django.http import HttpResponse def myview(request): return HttpResponse('MYVIEW LOL', content_type="text/plain") </code></pre> <p>I’m trying to use <code>reverse()</code> to get the URL, by passing it a function reference. But I’m not getting a match, despite confirming that the view function I’m passing to reverse is the exact same view function I put in the URL pattern:</p> <pre><code>&gt;&gt;&gt; from django.core.urlresolvers import reverse &gt;&gt;&gt; import urls &gt;&gt;&gt; from myapp import views &gt;&gt;&gt; urls.urlpatterns[0].callback is views.myview True &gt;&gt;&gt; reverse(views.myview) Traceback (most recent call last): File "&lt;console&gt;", line 1, in &lt;module&gt; File "/Library/Python/2.5/site-packages/django/core/urlresolvers.py", line 254, in reverse *args, **kwargs))) File "/Library/Python/2.5/site-packages/django/core/urlresolvers.py", line 243, in reverse "arguments '%s' not found." % (lookup_view, args, kwargs)) NoReverseMatch: Reverse for '&lt;function myview at 0x6fe6b0&gt;' with arguments '()' and keyword arguments '{}' not found. </code></pre> <p>As far as I can tell from the documentation, function references should be fine in both the URL pattern and <code>reverse()</code>.</p> <ul> <li><a href="http://docs.djangoproject.com/en/dev/topics/http/urls/#passing-callable-objects-instead-of-strings" rel="noreferrer">URL patterns with function references</a></li> <li><a href="http://docs.djangoproject.com/en/dev/topics/http/urls/?from=olddocs#reverse" rel="noreferrer"><code>reverse</code> with function references</a></li> </ul> <p>I’m using the Django trunk, revision 9092.</p>
