Hi, So i have users in the system and i have topics. Topics also have_many subtopics. What is the cleanest way to setup the AR relationships if a user can either have_many topics or subtopics ?

I''ve written a story and I run into a snag. I''ve written the create_forum method and told it to set the id to 1 but when it creates the forum the id is autoincremented. My forums table is empty but the id keeps incrementing the newest record on creation. When I run the story it comes out as something like 59 which fails my story because I''m asking it to look at /forums/1

I''m building a simple forum system which features a topics and a posts table. The topic model has a has_many association with the post model, i.e.: class Topic < ActiveRecord::Base { has_many :posts } class Post < ActiveRecord:Base { belongs_to :topic, :dependent => true } Now, I wish to sort the topics by the created_at property of the last post, but I can''t

As part of my Google Season of Docs project, I’ve been conducting a content audit of the LLVM docs. My goal is to identify specific categories and tasks under which the docs can be re-organized. One of my first suggestions will be to turn the main index (llvm.org/docs) into a landing page of sorts. Here’s an example of how the new index page might look: # Welcome/About * Introduction and

I have a User and Topic model. A user subscribes to a topic, so there is a many-to-many relationship between User and Topic. So my User model object is using has_many_and_belongs_to :topics and vice versa. I want to find all the topics that a user has *not* subscribed to. This is what I''ve got: @user = User.find(params[:id]) @topics = Topic.find(:all, :conditions =>
