After updating to ash 2.19.1, my many_to_many relationship started returning one resource struct instead of a list.
In my resource, I have this relationship:
many_to_many :schools, School do
through UserSchool
join_relationship :user_schools
source_attribute_on_join_resource :user_id
destination_attribute_on_join_resource :school_id
end
If i get the resource loading users_schools, I get the following:
...
user_schools: #Core.Accounts.UserSchool<
school: #Core.Accounts.School<
users: #Ash.NotLoaded<:relationship, field: :users>,

Before 2.19, I would get a list of all the user schools in that attribute.
