I have two models, users and themes, that I'm currently joining in a HABTM association in a themes_users table. Basically, after a user creates a new theme, it becomes available to other users to select for their own use. However, only the original creator of the theme should have the ability to edit it. So, I need to have some other ki...

class Question < ActiveRecord::Base belongs_to :author end class Author < ActiveRecord::Base has_many :questions end When I find some questions, I usually need to get their authors at the same time, so I use: Question.find(:all, :include=>:authors) But I don't write the ":include" part everywhere.

Sorry for the semi-generic title, but I'm still pretty new at rails and couldn't think of a succinct way to put the question.

I have a HABTM relationship on one of my models. I'm using formtastic for my forms. On a new action when choosing to output my column (HABTM) as check_boxes I see all my options appear, however they are all checked on by default. Ideally I want them to not be selected on a new action. When I uncheck a few options and save them, I will se...
I'm running into a problem viewing a list of 'category' checkboxes when I try to nest them in a fields_for form. I have a 'product' model that 'has_many' 'photos' which 'has_and_belongs_to_many' 'categories'. I'm pretty sure all my associations in my models are correct, as is my joins table for the 'photos' and 'categories' relations...
