I need an easy way to grab layouts that are found in /app/views/layouts. I technically can go in there from Rails.root and grab all files I can, but I'm sure there's a better way. Rails knows where to look for layouts and what extensions are ok. I tried to dig through actionpack but nothing popped out at me. Thanks ...

Maybe I have misunderstood the whole concept of Arel, and I would be grateful if anybody could have a look at it. The expected result of th...

I'm trying to set up a rather complex form using form_for. This form needs to be in multiple views, where some fields would be available across all actions and other fields are specific to each individual actions.

For example I have a comments models, and I have a post model, but comments can comment on other comments. So it seems I need a join table I'll call commentables. To create this, do I really need to create a commentable table with a post_id and a comment_id ? Or can I do something like this without one : has_many :comments...
I'm not exactly sure what my problem is, so this question may require some more clarification, but here's what seems to be most relevant: I have a has_many :through and the join model has some fields that aren't foreign keys. When I build the models up and try to save I get a validation error on the non-foreign key fields from the join...
