问题 I'm a newbie and I just showed my code to an expert, that told me I shouldn't use has_many to filter my variables, but scopes . I have three models : User, Product and Ownership. So here is my code in app/models/user.rb : class User has_many :ownerships, foreign_key: "offerer_id", dependent: :destroy has_many :owned_products, through: :ownerships, source: :product has_many :future_ownerships, -> { where owning_date: nil, giving_date: nil }, class_name: "Ownership", foreign_key: "offerer_id"

Can you have a belongs_to belongs_to relationship in Rails? Search results gave me two results. The fact that I can't find very much info on the subject, seems to indicate that it shouldn't be done or is bad practice. I asked yesterday about a has_many relationship, but thought because I couldn't find information on this, I would generate a question so it is easier for people to search for this in the future. I'm paraphrasing another users answer (I hope this is ok). A Shoe can have many Socks, but only one active Sock. Other Socks are inactive. All Socks are also unique with unique patterns.
