Hi i am still very new to ROR, i hope you can help me with this problem.

i have two modles, Place and User

users plant to go to places users have been to places users live in the places

these are 3 relationships. how do i write "has_many" statement to make ROR take care them for me?

or i have to write my own codes for them?

thanks.

i'm still new too, but i think one way is to make join models representing each relationship:

e.g.

make a migration: def self.up   create_table :planned_places do |t|     t.column :place_id, :integer     t.column :user_id, :integer   end   create_table :visited_places do |t|     t.column :place_id, :integer     t.column :user_id, :integer   end   create_table :lived_places do |t|     t.column :place_id, :integer     t.column :user_id, :integer   end end

then in your model; has_many :planned_places has_many :visited_places has_many :lived_places
