    <p>Note that best practice in Python 2.7 is to use <em><a href="https://www.python.org/doc/newstyle/" rel="noreferrer">new-style</a></em> classes (not needed with Python 3), i.e.</p> <pre><code>class Foo(object): ... </code></pre> <p>Also, there's a difference between an 'object' and a 'class'. To build a dictionary from an arbitrary <em>object</em>, it's sufficient to use <code>__dict__</code>. Usually, you'll declare your methods at class level and your attributes at instance level, so <code>__dict__</code> should be fine. For example:</p> <pre class="lang-python prettyprint-override"><code>&gt;&gt;&gt; class A(object): ... def __init__(self): ... self.b = 1 ... self.c = 2 ... def do_nothing(self): ... pass ... &gt;&gt;&gt; a = A() &gt;&gt;&gt; a.__dict__ {'c': 2, 'b': 1} </code></pre> <p>A better approach (suggested by <a href="https://stackoverflow.com/users/409638/robert">robert</a> in comments) is the builtin <a href="https://docs.python.org/3/library/functions.html#vars" rel="noreferrer"><code>vars</code></a> function:</p> <pre class="lang-python prettyprint-override"><code>&gt;&gt;&gt; vars(a) {'c': 2, 'b': 1} </code></pre> <p>Alternatively, depending on what you want to do, it might be nice to inherit from <code>dict</code>. Then your class is <em>already</em> a dictionary, and if you want you can override <code>getattr</code> and/or <code>setattr</code> to call through and set the dict. For example:</p> <pre><code>class Foo(dict): def __init__(self): pass def __getattr__(self, attr): return self[attr] # etc... </code></pre>

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.
