    <p>Is there a better way to write this code? I know it's very simple, but the way I wrote it seems so repetitive.</p> <p>I'm not necessary looking for a one-line genius code, just some other readable, useful alternative.</p> <p>Thanks in advance!</p> <pre><code>def __unicode__( self ): location = [] if self.room != None: location.append( self.room ) if self.floor != None: location.append( self.floor ) if self.building != None: location.append( self.building ) location.append( self.property ) return ", ".join( location ) </code></pre> <p><code>self.property</code> is always set, which is not true for <code>self.room</code>, <code>self.floor</code>, and <code>self.building</code>. By the way, this is part of the <code>models.py</code> of a Django code in case anyone is wondering.</p> <p><em><strong>Side question</strong></em>: Is using <code>property</code> as a variable name a bad idea? I noticed <code>property</code> gets highlighted under syntax, but I looked it up and it's not a <a href="http://docs.python.org/reference/lexical_analysis.html#keywords" rel="nofollow">Python reserved word</a>.</p> <p>Here is the complete class:</p> <pre><code>class Location( models.Model ): def __unicode__( self ): location = [] if self.room != None: location.append( self.room ) if self.floor != None: location.append( self.floor ) if self.building != None: location.append( self.building ) location.append( self.property ) return ", ".join( location ) comments = models.TextField( blank = True ) room = models.CharField( max_length = 135, blank = True ) floor = models.CharField( max_length = 135, blank = True ) building = models.CharField( max_length = 135, blank = True ) property = models.ForeignKey( Property ) t_created = models.DateTimeField( auto_now_add = True ) t_modified = models.DateTimeField( auto_now = True ) </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.
