  • Nested Model/Routes in Rails 3

    - by mbreedlove
    I have a simple blogging functionality in my Rails 3 app. I am trying to add commenting to each post. The BlogComment model has a property, blog_post_id, to be able to find the corresponding comments for each post. I already setup my associations in the model, I also nested BlogComments under BlogPost in the routes file. However, I can't figure out how to give each BlogPost access to its respective comments through the controller so that they can be shown later in the view.

  • Rails cookies not working right

    - by Michael Waxman
    Rails is setting and returning a remember_token cookie like this: = cookies[:remember_token] = value6c69b17681d2bf316f8eexpiresThu Jun 10 14:55:00 -0400 2010 In other words, when I'm calling the cookie I don't just get the value. Why is this? I am setting the cookie as follows: cookies[:remember_token] = { :value => @user.remember_me, :expires => 1.year.from_now} What's going on here?

  • Rails - before_save that includes updated object

    - by Sam
    I have a before_save that calculates a percentage that needs to include the object that is being updated. Is there a one-liner in Rails that takes care of this? for example and this is totally made up: Object.find(:all, :include => :updated_object) Currently I'm sending the object that is getting updated to the definition that calculates the percentage and that works but it's making things messy.

    Hi, is it possible to have the controller value in a rails named route as a parameter, which I can pass at runtime to direct the call to the proper controller? e.g. map.ride 'ride' ,:controller = {some-way-of-specifying-a-parameter}, :action = 'ride' then at runtime, I want to pass the controller name to which this call should be going. My actions are doing different things depending to which controller the call gets sent. thanks
