Fragment Caching (revised)
If you need to cache a certain section of a page instead of the entire page, fragment caching is the way to go. Learn how caching is stored, how to create auto expiring caches, and more.

HABTM Checkboxes (revised)
A many-to-many association can be edited through check boxes in a form. Here I show how to do this with a has_many through association complete with clickable labels.
(6 minutes)
Dynamic Select Menus (revised)
Do you need to dynamically change one select menu based on the value of another? Here I show how to filter states/provinces by a selected country using grouped options and a dab of CoffeeScript.

Advanced Search Form (revised)
It is often best to use a GET request when submitting a search form, however if it is an advanced search form with a lot of fields then this may not be ideal. Here I show how to create a search resource to handle this.
(6 minutes)
Sortable Lists (revised)
Here I show how to use jQuery UI to make a sortable list and a "sort" action to handle the updating. Top it off with acts_as_list to make it feature complete.
