| # Computes STI models who are grandchildren or more. | |
| # | |
| # In a STI the root class and its subclasses work normally, but if there are | |
| # grandchildren we need to preload them. Reason is, given A < B < C, if you | |
| # for example compute B.count without loading A, only B records are taken into | |
| # account in the query (where a clause about the type column intervenes). This | |
| # is not a bug, Active Record is simply not aware of A. Once it is, the clause | |
| # becomes an OR with all relevant types. | |
| # | |
| # I used this script to compute them. |

Rails is a Ruby framework that includes everything needed to create web applications. This was our fourth Summer of Code participation, and in this post we'd like to tell you a bit about this year's projects.
Andrei has added support for several types of Source Maps to Sprockets 4. With Source Maps users can see a readable version of their code inside Developer Tools (Javascript, CSS, etc.) after it's been minified or compiled. Check out Andrei's
