    1. COCan you post the portion of the output from `rake routes` that includes the route specification for `contest/commentable` so we can confirm how Rails thinks things should be routed?

    2. CO@normalocity I added the model information to the top of the question, which should clarify how the routes are generated.

    3. COWell, you're probably right, but `rake routes` is the **truth** when it comes to how the Rails is actually interpreting routes, so I'd rather see that output. The model information does tell me the relationships, but routes can be overridden, non-default, or otherwise not what you expect, which is why you should check `rake routes` to get this information.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
