Question

Rails ACL

Asked by: mdlittle

I'm new to rails and I'm having problems figuring out how to limit the ability to for 1 user to see the records that another user creates. I have Users and Children and I want to make it so a User with user_id of 1 who creates children_id of 8,9 can only see children 8,9. I also want to make it so User_id 2 cannot see user_id 1 or children 8 and 9. I am using restful_authentication.

My guess from your question is that you already have an has_many association from the User => Child model.  ie, something like:

  class User < ActiveRecord::Base
     has_many :children
  end

  class Child < ActiveRecord::Base
     belongs_to :user
  end

Given this, you probably are trying to work out how to make sure a user only can ask for the URLs to their own children.

If this is the case, you are trying to find the code for the following snippet:

  ChildrenController < ActionController::Base
    def show
      @child = Child.find(params[:id]
    end
  end

If this is your current code, then the user can ask for any child, theirs or not.

To fix this, use the User => Child has_many association:

  ChildrenController < ActionController::Base
    def show
      @child = current_user.children.find(params[:id])
    end
  end

This way the User can only look at children that can be found from within the user's children collection.

I don't use Restful Athentication at the moment, but I believe "current_user" returns the current user object from the database.

Hope that helps
