Scenario:
Team
has_many :players, dependent: :destroy
has_many :users, through: :players
Player
belongs_to :team
belongs_to :user
User
So, let's say that i have 4 teams with different users:
Team 1
User 1, User 2
Team 2
User 2, User 3
Team 3
User 1
Team 4
User 2, User 4, User 5
Now, suppose i have the id of two users, (User 1, User 5), and i want to know if there is any team which consists of ONLY these two players. Let's say i have a team that consists of users 1, 2 and 5. The query should not bring this team.
How can i use ActiveRecord semantics in my favor to do this? It is easy to get all players from a team, but i couldn't find a way to do the opposite.
