This question should be rather easy, but being fairly new to RoR I’m not
sure of the best way to proceed…
I have 2 models: City and Location… Both model belong to the Country
model…
(So basically a Country has many cities and many locations)
Now the tricky part is that… a city can also have Locations…
From there, I’m not sure where to go…
My first idea was to go with the following relationships:
Location:
belongs_to :city
belongs_to :country
City:
belongs_to :country
has_many :locations
Country:
has_many :cities
has_many :location
However, I realized that this meant Locations will have both a city_id
and a country_id field…in some case, the country_id would be empty, in
other cases, the city_id would be empty (depending if the Locations
belongs to a city or a country)… Would this work? Somehow this doesn’t
sound right?
I read a bit on polymorphic association… could this be a better idea
for what I’m trying to do?
Any help would be appreciated!
