  1. POdjango-experiments and Django 1.5: NoReverseMatch error
    text
    copied!<p>I've found a number of incompatibilities with Django 1.5 in django-experiments, nexus, and gargoyle. Fortunately, almost all of them have been fixed by quoting the first parameter to the "url" templatetag everywhere it occurred.</p> <p>I'm stuck against something I haven't been able to figure out -- I'm getting the following error when I go to my goal page:</p> <pre><code>NoReverseMatch at /trial/trial1/ Reverse for 'experiment_goal' with arguments '(u'clicktrynow',)' and keyword arguments '{}' not found. </code></pre> <p>I'm running Django 1.5.1 and Python 2.7.3 on runserver. I can also reproduce this in Python 2.7.4 on Heroku.</p> <p>My goal page (reaching this page is accomplishing the goal) has this line in it:</p> <pre><code>{% experiment_goal "clicktrynow" %} </code></pre> <p>The experiment_goal templatetag appears to automatically include the experiments/goal.html template at this point. experiments/goal.html contains:</p> <pre><code>&lt;img src="{% url 'experiment_goal' goal_name %}?v={{ random_number }}" height="1" width="1" /&gt; </code></pre> <p>(I've fixed quoting on 'experiment_goal'.)</p> <p>The urlpatterns for the django-experiments app contains this line:</p> <pre><code>url(r'^goal/(?P&lt;goal_name&gt;.*)$', 'record_experiment_goal', name="experiment_goal"), </code></pre> <p>Finally, my settings.py lines relevant to django-experiments are:</p> <pre><code>EXPERIMENTS_REDIS_HOST = get_env_variable('REDISTOGO_URL', default='redis://localhost:6379') EXPERIMENTS_REDIS_PORT = 6379 EXPERIMENTS_REDIS_DB = 0 INSTALLED_APPS += ('django.contrib.humanize', 'nexus', 'gargoyle', 'experiments', ) MIDDLEWARE_CLASSES += ('experiments.middleware.ExperimentsMiddleware', ) EXPERIMENTS_GOALS = ('clicktrynow', ) </code></pre> <p>I'm new to Django, but all of this seems like it should work. What am I missing?</p> <p>Update: My project's urls.py does not include a urls.py from django-experiments. Documentation doesn't say you need to. But perhaps I should. Investigating...</p>
