If I do something like: result = Appointment.find( :all, :include => :staff ) logger.debug { result.inspect } then it only prints out the Appointment data, and not the associated staff data.

I can't seem to get JSON.pretty_generate() to actually generate pretty output in Rails. I'm using Rails 2.3.5 and it seems to automatically load the JSON gem. Awesome. While using script/console this does indeed produce JSON: some_data = {'foo' => 1, 'bar' => 20, 'cow' => [1, 2, 3, 4], 'moo' => {'dog' => 'woof', 'cat' => 'meow'}} som...

In my current project (Rails 2.3) we have a collection of 1.2 million keywords, and each of them is associated with a landing page, which is effectively a search results page for a given keywords. Each of those pages is pretty complicated, so it can take a long time to generate (up to 2 seconds with a moderate load, even longer during tr...

I have a live rails website and I want to have a form with a lot of fields on it. I have set up validations and allowed formatting for every field. I've tested it quite a bit and it seems to catch anything I throw at it. I think it's almost ready to go live, but I want to quadruple check if there's anything else I should do to protect it...

So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, t...
I'm working on unit testing an ActiveResource model in my Rails application. I have my ActiveResource::HttpMock code in my test file as follows: ActiveResource::HttpMock.respond_to do |mock| mock.get "/audience/42/people/1.xml", {"Authorization" => "Basic VTExbTJCTzhkZzNMOmFpdU1nbHZJT2taakdPV3A=", "Accept" => "application/xml"}, @some...

Rails has an annoying "feature" which displays ALL validation error messages associated with a given field. So for example if I have 3 validates_XXXXX_of :email, and I leave the field blank I get 3 messages in the error list. This is non-sense. It is better to display one messages at a time. If I have 10 validation messages for a field d...
