How can I allow a specific server/url to send for example a post request if I have activated protect_from_forgery in a Ruby on Rails application? Usually it is a desired behaviour that a Rails application blocks requests from other servers and so I also want to keep this functionality and I do not want to switch protect_from_forgery off....
I recently started a project where the team decided we'd like to use jQuery rather than Prototype/Scriptaculous for our javascript needs. We set our project up, and began the switch. The plugin was installed via these instructions, and all went according to plan. Shortly after, when trying to run "./script/server", we get the followin...
Hi, I have textmate 1.5.7 running on my leopard machine. When programming in rails, for some reason some key words do not get highlighted. For example: validates_presence_of, has_many, remote_form_for (form_for gets highlighted) etc... I tried switching themes and it did not help. I also tried upgrading to the most recent rails bundle ...

I have two scaffold-generated models: Book and Bookbag. A Bookbag has-many Books, and a Book belongs-to a Bookbag. Each Book has a weight, and each Bookbag has an average-weight that is supposed to store the average weight of all of its Books. What is the best way to keep average-weight up to date? Using a before-save filter on Bookba...
I am using Sphinx with the Thinking Sphinx plugin to search my data. I am using MySQL. My data contains accented chars ("á", "é", "ã") and I want them to be equivalent to their non-accented counterparts ("a", "e", "a", for example) when searching and ordering.

I'm trying to fool a very complex black box into displaying some floats differently (it's the Gruff graphing library, so this is being rendered to an image). In the console, I can paste this: logger = RAILS_DEFAULT_LOGGER logger.debug "Here's a float #{455.67.to_s}" eval %{class Float def to_s_with_time h = (self / 60...

OK I'm sure I'm missing something here, but please forgive me I'm new to Rails. Is there some way in Rails to display all the fields for an object rather than specifying each?

In this post I'm only concerned about the relation user_tags, tags: I'd like to avoid that linked tags can be deleted. Only tags which aren't referenced should be destroyable. The stupid way to do this would be: class Tag def before...
