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
