Hello all, Let me explain a fairly complex problem, I am blocked and if someone could give me a boost I can thank him enough!
The concept: ------------- I have a series of tables in DB (users, functions, expertize, ...) I want to put in place a system that would allow me to link these different objects between them in a very flexible one table. My idea: ------------- Create a table "objectrelations" containing the following fields: id linkfrom_id linkfrom_type linkto_id linkto_type created_at updated_at stopped_at # 1 record objectrelations: id: 1 linkfrom_id: 1 # User ID = 1 linkfrom_type: "User" linkto_id: 1 # expertize ID = 1 linkto_type: "expertize" created_at: now () updated_at: now () stopped_at: NULL The problem: -------------------------- This works well in DB, it allows me to create links between different objects, back links, to end a relationship (via the column stopped_at) without removing the link DB (it keeps a history) ... As against, I don't find how to implement this model in Rails (in models). I think I understand that I will use the polymorphism, the "Through Associations" or "Single table inheritance" but I don't know how. I looked at the side of "acts_as_taggable", they use a system similar but only in one direction (any object -> tags). Unfortunately, here I must be able to link anything with anything ... Does anyone have an idea to help me? How should I do this ?
