Body
Let's say I have classes <code>Base(object)</code> and <code>Derived(Base)</code>. These both implement a function <code>foo</code>, with <code>Derived.foo</code> overriding the version in <code>Base</code>. However, in one of the methods, say <code>Base.learn_to_foo</code>, I want to call <code>Base.foo</code> instead of the derived version regardless of whether it was overridden. So, I call <code>Base.foo(self)</code> in that method: <pre><code>class Base(object): # ... def learn_to_foo(self, x): y = Base.foo(self, x) # check if we foo'd correctly, do interesting stuff </code></pre> This approach seems to work and from a domain standpoint, it makes perfect sense, but somehow it smells a bit fishy. Is this the way to go, or should I refactor?

1. COWhy override `foo` in the first place, in a way that makes it unsuitable as replacement for `Base.foo`?

2. CO@delnan: because it is suitable as a replacement everywhere *except* in `learn_to_foo`.

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.
