    <p>(Sorry. The title's pretty unclear. I couldn't come up with a good one.)</p> <p>Say I have a url like so (it's root-relative): </p> <pre><code>"/forums/support/windows/help_i_deleted_sys32/6/" </code></pre> <p>and I'm trying to split this into a class structure like this:</p> <pre><code>class Forum_Spot: def __init__(self, url): parts = url.strip("/").split("/") #parts is now ["forums", "support", "windows", "help...", "6"] self.root = "forums" self.section = "support" self.subsection = "windows" self.thread = "help..." self.post = "6" </code></pre> <p>but say I don't know how long exactly the url will be (it could be "/forums/support/", "/forums/support/windows/", etc) (but I do know it won't be any deeper than 5 levels). Can anybody think of an elegant way to assign these values, letting any parts not assigned be <code>None</code>? (I.e. for "/forums/support/windows/", the thread and post attributes would be None)</p> <p>I know I could do this:</p> <pre><code>class Forum_Spot: def __init__(self, url): parts = url.strip("/").split("/") #parts is now ["forums", "support", "windows", "help...", "6"] if len(parts) &gt; 0: self.root = parts[0] else: self.root = None if len(parts) &gt; 1: self.section = parts[1] else: #etc </code></pre> <p>but this is obviously superinelegant and obnoxiously labor-intensive. Can anybody think of a more elegant solution, keeping the class signature the same? (I could convert the <code>__init__</code> function to take keyword parameters, defaulting to <code>None</code>, but I'd like to be able to just pass in the url and have the class figure it out on its own)</p> <p>Thanks!</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.
