    <p>I found a pretty hacky way to do this. I wrote the following function to override the <code>__builtins__.help</code> function:</p> <pre><code>def partialhelper(object=None): if isinstance(object, functools.partial): return pydoc.help(object.func) else: # Preserve the ability to go into interactive help if user calls # help() with no arguments. if object is None: return pydoc.help() else: return pydoc.help(object) </code></pre> <p>Then just replace it in the REPL with:</p> <pre><code>__builtins__.help = partialhelper </code></pre> <p>This works and doesn't seem to have any major downsides, yet. However, there isn't a way with the above naive implementation to support still showing the <code>__doc__</code> of <em>some</em> <code>functools.partial</code> objects. It's all or nothing, but could probably attach an attribute to the wrapped (original) function to indicate whether or not the original <code>__doc__</code> should be shown. However, in my scenario I never want to do this.</p> <p>Note the above does NOT work when using IPython and the <a href="http://ipython.org/ipython-doc/dev/interactive/reference.html#embedding-ipython" rel="nofollow">embed functionality</a>. This is because IPython directly sets the shell's namespace with references to the 'real' <code>__builtin__</code>, see the <a href="https://github.com/ipython/ipython/blob/master/IPython/core/interactiveshell.py#L1121" rel="nofollow">code</a> and old <a href="http://mail.python.org/pipermail/python-dev/2001-April/014068.html" rel="nofollow">mailing list</a> for information on why this is.</p> <p>So, after some investigation there's another way to hack this into IPython. We must override the <code>site._Helper</code> class, which is used by IPython to <a href="https://github.com/ipython/ipython/blob/master/IPython/core/interactiveshell.py#L1136" rel="nofollow">explicitly setup the help system</a>. The following code will do just that when called BEFORE <code>IPython.embed</code>:</p> <pre><code>import site site._Helper.__call__ = lambda self, *args, **kwargs: partialhelper(*args, **kwargs) </code></pre> <p>Are there any other downsides I'm missing here?</p>

    1. COIt's also worth noting this will NOT work in IPython. I'm sure there's a way around it, but IPython doesn't have `__builtins__.help` even though the `help()` function is available in the global namespace. Suggestions?

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.
