在Rails中与同一个类进行多个关联的最佳实践？

class User< ApplicationRecord
  has_many :memberships
  has_many :projects, through: :memberships
end

class Project< ApplicationRecord
  has_many :memberships
  has_many :users, through: :memberships
end

class Membership< ApplicationRecord
  belongs_to :user
  belongs_to :project
end

user = User.find(1)
projects = user.projects

project = Project.find(1)
users = project.users
