This is a complete demonstration of many-to-many relationship using has_many :through between two models.
Here we have Team and Player models where each can contain many of other.

Like, a team has many players and a player has many teams. They are related through Contract model which has player_id, team_id and offer columns.

The focus is to show

  • Nested forms to create two new resources while being connected.
  • Creating one new resource linked with an existing another resource.
  • Creating a relation between two existing records.
