At the bottom of the page, you pring the the entire controller, but the signin method there is missing the "if request. Don't know is this is Rails 2. At least using Rails 2. So I think that the AddRolesAndRightsTables migration may need an update.

I couldn't find this is the errata. Since I'm still waiting for the printed book and have no access to the beta, I'm referering to the excerpt so this error might have been fixed already. Before you can switch the locale and create a translation here in ar-LB you need to explicitely save and reload the record with the base locale.
This produces a three part email, instead of the desired two, and Mail at least presumes that the first part is the plain text alternative, which causes some problems. It should be more clear than "The default generated model, Delivery, is sufficient for our needs on the Ruby side of the house.
The code in the book for whitelists doesn't work. But the new code posted in the resources section: I'm not sure why.
The Django template language: for Python programmers | Django documentation | Django
