Hey everyone... I''m just getting my feet wet with relational databases using RoR models. The software I''m putting together relies on car parts. Originally I had the database set up as follows create_table :parts do |t| t.column :year, :string t.column :make, :string t.column :model, :string . . . end However, I now realize it''s much better to do it using

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 ? Its basically a dual select box dropdown, where the second dropdown is optional. Is the best to have user_topics, and user_subtopics tables and manage that way ? or combine into one table with STI

It seems that using a join model that joins with two has_many''s will fail to generate proper SQL class StudentSemesterRecord < ActiveRecord::Base belongs_to :semester has_many :discipline_records, :through => :semester end class Semester < ActiveRecord::Base has_many :student_semester_records has_many :discipline_records end class DisciplineRecord <

I discovered an interesting aspect of has_many behavior that I''m struggling to work around. I''m not sure if I''m doing something wrong, or if it''s a legitimate bug, or if it''s an inherent part of Rails that I just have to learn to deal with.

Am interested in the new PATCH method that will be included in Rails 4, but have a question/concern, and forgive me if I''m misunderstanding it. So, if the request parameter _method is set to "patch", the update is processed as a patch.
