Multiple Relations between 2 tables


#1

So I am trying to figure out how I would go about creating the
relationships between two tables, but there are multiple relationships
happening.

The one I am trying to figure out is a one_to_one relationship + a
one_to_many relationship.

Example:
I have a home model and a location model
home has_one location
location has_many homes

The trouble is I have to be able to access both home.location and
location.homes
I don’t want to have locations duplicate if multiple homes have the same
location.

Any help on this would be great!

class Home
belongs_to :location
end

class Location
has_many :homes
end

Now @home.location and @location.homes are available. has_one doesn’t do
exactly what you’re hoping it would. Use belongs_to.
