    <p>This might be a complicated explanation. Here it goes.</p> <p>There are two models in the scope of this problem, <code>Asset</code> and <code>AssetGroup</code>. <code>AssetGroup</code> contains information about a 'group' of assets (e.g. brand, model, specifications) and <code>Asset</code> contains individual asset information (e.g. cost, date of purchase, reason for purchase, asset group).</p> <p>Obviously, a relationship exists between the two models, (e.g. assets belong to a certain 'group').</p> <p>So a person at this company goes to add a product to the database using Django's admin interface, and they have to select a group for their asset to belong to. The select-box for the asset group shows the <code>__unicode__</code> method for each asset group (of course), and the <code>__unicode__</code> method I'm using is a concatenation of the asset group brand, model, and sub-model:</p> <pre><code>def __unicode__(self): return self.asset_brand + " " + self.asset_product + " - " + self.asset_subproduct </code></pre> <p>Easy enough.</p> <p>Now, there are multiple entries in the <code>AssetGroup</code> table that end up with the same <code>__unicode__</code> method output, e.g. there are two items with:</p> <ul> <li><code>asset_brand = 'Apple'</code></li> <li><code>asset_product = 'Macbook Pro'</code></li> <li><code>asset_subproduct = 'Mid-2009'</code></li> </ul> <p>so they look exactly the same. The reason that they are separate entries in the first place is because there's a field in <code>AssetGroup</code> called <code>asset_description</code>, which holds additional information about the <code>AssetGroup</code> (e.g. the first Macbook Pro <code>AssetGroup</code> object might have 4GB of RAM, and the second <code>AssetGroup</code> object might have 8GB of RAM).</p> <p>So obviously there are two different products which look the same in the select-box when the client is entering an asset into the database. I'd like to (dynamically, using JS) show the selected <code>AssetGroup</code>'s <code>asset_description</code> to the client when they're entering an <code>Asset</code> into the database.</p> <p>Is there anything in Django that does this? If not, I guess I could redesign my database, but I really don't want to.</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.
