    <p><strong>TL;DR:</strong> <code>request.method</code> is never <code>None</code> in real use, but for your particular case, you're looking at the wrong thing.</p> <h1>Generic <code>HttpRequest</code></h1> <p><code>django/http/__init__.py</code>:</p> <pre><code>class HttpRequest(object): ... def __init__(self): ... self.method = None ... </code></pre> <p>When a plain <code>HttpRequest</code> is instantiated, its method is <code>None</code>. But then, <code>WSGIRequest</code> and <code>ModPythonRequest</code> don't call <code>HttpRequest.__init__</code> ever.</p> <h1>Requests through <code>mod_wsgi</code></h1> <p><code>django/core/handlers/wsgi.py</code>:</p> <pre><code>class WSGIRequest(http.HttpRequest): ... def __init__(self, environ): ... self.method = environ['REQUEST_METHOD'].upper() ... </code></pre> <p>The summary of this is that for mod_wsgi, <code>request.method</code> will <em>never</em> be <code>None</code>. If in some warped way you managed to get <code>environ['REQUEST_METHOD']</code> not being defined or being <code>None</code>, the request would fail.</p> <h1>Requests through <code>mod_python</code></h1> <p><code>django/core/handlers/modpython.py</code>:</p> <pre><code>class ModPythonRequest(http.HttpRequest): ... def _get_method(self): return self.META['REQUEST_METHOD'].upper() ... method = property(_get_method) </code></pre> <p>Same remarks as with <code>WSGIRequest</code> apply. Can't ever be <code>None</code>.</p> <h1>Test client</h1> <p><code>django.test.client.RequestFactory.request</code> instantiates a <code>WSGIRequest</code> and is called every time with <code>REQUEST_METHOD</code> defined in the <code>environ</code> as an uppercase string, as it should be.</p> <hr> <p><strong>Summary:</strong></p> <pre><code>assert request.method is not None </code></pre> <p>You're looking for the error in the wrong place. In this case, <code>request.method == 'POST'</code>. It's failing when <code>request.META.get('CONTENT_TYPE', '') is None</code>. The reason for this is that the <code>Content-Type</code> header isn't being sent by the client in the request (don't ask me why, I'm not familiar with that stuff).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
