Is there a good tutorial/guide/blog post/book chapter/screencast/etc that attempts to comprehensively cover everything having to do with locks, transactions, and isolation levels in ActiveRecord? (preferably relevant to Rails 4.0) There's a brief section in the guides, and of course some API docs, but it's a really important and (for me) hard-to-understand domain, and it's my first time trying to take data integrity seriously in my Rails app. I'd like to get a good understanding so I can do it properly.

Guidance

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.
