Hi,
I’m trying to create a model where a few objects can all be linked to
each other through a central linking table. Table structure is like
this:
– model class Computer
create table computers (
id serial,
description varchar
);
– model Class user
create table users (
id serial,
name varchar
);
– model class Desk
create table desks (
id serial,
location varchar
);
– The linking table
create table linkings (
source_id int,
source_type varchar,
link_id int,
link_type varchar,
created_at timestamp,
comments varchar
)
I want to use has_many / belongs_to or some other association to be
able to have any number of objects from different types linked to each
object. I don’t want to create multiple linkings tables for that, as
the more objects I have the increase in number of tables will be huge.
Any way to cleanly solve this?
I tried also with the latest edge with the new polymorphic relations,
but still can’t get it to do work this way.
Thanks,
Guy.
