Question

In my database, OptionSets are associated with other OptionSets. If I was joining two separate tables I would create a simple join table. However, Rails likes to have its foreign keys named <singular_table_name>_id, i.e. optionset_id. However, if I am joining the table with itself I obviously cannot give the two tables the same name. How do I deal with this?

create_table :optionsets_optionsets do |t|
  t.column :optionset_id, :integer
  t.column :dependent_optionset_id, :integer # how do i deal with this?
end
