I have 2 ecto schema models that have a man_to_many relationship.
schema "Users" do
many_to_many :locations, Location, join_through: "locations_users"
end
schema "Locations" do
many_to_many :users, User, join_through: "locations_users"
end
So in my User.ex schema model file how should I go about writing a function to add and also to remove a user?
def add_location(location) do
# ???
end
def remove_location(location) do
# ???
end
In the ecto docs it says you shouldn't have to load all the associated data before adding/removing an association item, you can just set the association. But since I am using a many to many, I'm not sure how I can just set the association since it is a join table only.
