    1. COI think Keltex may have meant in the answer post, rather than the blog. I hardly ever go to a 3rd party site and download source, but like looking through code samples of the core sections on here, or even on the blog :)

    2. COOh I see. I started doing that, but the code was getting crazy big, So I figured it wasn't worth repeating. I can see that posting code snippets would be useful, but for posting the 4-5 classes that are needed in this case might be overkill. Still, I can do that if it's what is wanted. Thoughts?

    3. COPeople on SO don't seem to mind long answers, as long as they're descriptive (see http://stackoverflow.com/questions/1863884/which-orm-supports-this/1866687#1866687 for an example). That being said, I believe you could condense the code from my answer below down to ~40 lines if you wanted to only do radio buttons rather than the multiple input types it handles, and I'm sure that you could do the same with yours. Feel free to use of the code in my answer if it makes it easier :)

Querying!

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).
