It looks rails automatically creates a "finder" method on models that have a "belongs_to". So I tried this in the console: c = Category.find(2) chunks = Chunk.find_by_category(c) chunks is always returned as an empty array. When I know have some chunks with a category_id of 2. Should the find_by_category do what I think it should be doing or am I completely off base?

Say I have a post model that has_and_belongs_to_many :categories, and a category model that has_and_belongs_to_many :posts. So I have a categories_posts table to do the join. That''s all find and dandy. However I want to be able to find all the posts that belong to a specific category. I tried Post.find_by_category(:id) but that doesn''t work. Does anyone have any insight?

All, This is more of a theoretical question I suppose - I''m looking for what the consensus is for the "correct" approach in Rails/MVC. I have a standard security model where a User can have many Roles. There is a User model, a Role model, and in the db, a linking table, etc. Each role has a name as well as a category (say, name="waiter", category="restaurant

I have a model, listing, which belongs_to one or more categories. I need the user to be able to search for categories by name (which I can do) and have it return all the listings that belong to those categories. This I can do. However, what I need to do is take that list of listings and sort them by one of their fields. This is a bit more complicated, without needing to sort I could just do:

Hi there, My routes.rb is something like map.connect '':controller/:action/:id'' However, when a url request likes http://xxx/user/category/a/b My intension is to call :controller => ''user'' :action => ''category'' :id => ''a/b'' However, :id has slash in it (a/b) will make rails fail to route.

Dear R's! I am strugling with cancor procedure in R. I cannot figure out the meaning of xcoef and of yxcoef. Are these: 1. standardized coefficients 2. structural coefficients 3. something else?

I found a thread on the CentOS Forums (I don't have an account

I just came to the conclusion that the rid backend has been very much underappreciated. Too much mental inertia about how things used to be made? After strugling for two days to configure a member server against a Samba Active Directory with the ad/RFC2307 backend, I turned to the rid backend and voil?! all my problems are gone.
