I'm just learning how to program in Ruby on Rails, and I'm really impressed by how much work the Ruby on Rails framework does for you. I have the following two classes: Object -------- object_id description ObjectGroup -------- group_id description The idea is that I have some objects, and I'd like for the users to be able to define...
How do I send a cookie in a functional test? How do I test to be sure that the cookie is cleared? I've had great success using TDD to build the models for a Rails application, but have hit a snag with regard to controller testing: I can set cookie values once in a test and read them, but I can't clear them. That is: test "clears cookie...

The Rails console doesn't seem to like multiple ruby statements on the same line separated by a semicolon. Whenever I do this, the next line starts with ?> and I find that only the first statement was executed. Do you have to put each statement on a separate line? >> user = User.new user = User.new => #<User id: nil, username: "", hash...

While load_paths only contains 'app/models', it appears that the initialization steps recursively caches everything in 'app/models'. # Eager load application classes def load_application_classes if configur...

What kinds of practical uses are there for Ruby modules in a rails app? I would appreciate if someone could mention an example of where they've actually u...

I just want to make it clear what I'm trying to do here. Scenario So, there's a model Foo, each Foo can either be red, green, or blue. Having URLs like /reds to list all red objects, and /red...
Hey all, I am completely lost on this one. I found a code snippet online to help validate fields via ajax as the user types into them. So I'm trying to write a spec against part of it and I just can't get it to pass. Here's the code def validate field = params[:field] user = User.new(field => params[:value]) output = "" user...
One of my Rails applications is going to depend on a secret key in memory, so all of its functions will only be available once administrator goes to a certain page and uploads the valid key. The problem is that this key needs to be stored securely, so no other processes on the same machine should be able to access it (so memcached and ...

To solve the caching issue I would like to have url like /users/2/events/2009-02.html . I have defined users to be a restful resource....
I'm attempting to create a hierarchal menu system in rails. My menu model is in a tree data structure, and I need to pass the parent information to the new action. The best way i found to do this was to pass the parent's id as a querystring. This works, unless validation blocks creation. The problem is that after the new view is rendere...
