Ruby on rails 创建studio组时，如何将所有者作为成员添加到studio组中？

现在，每当我创建工作室时，当前用户都会成为工作室的所有者，但他不会成为工作室的成员。这样做的方式是什么

控制器：

class StudiosController < ApplicationController

  def create
    @studio = Studio.new(studio_params)
    @studio.owner = current_user

    respond_to do |format|
      if @studio.save
        format.html { redirect_to @studio, notice: 'Studio was successfully created.' }
      end
    end
  end

  def members
    @members = studio.memberships

    @membership = Membership.new
  end
end

class MembershipsController < ApplicationController

  def create
    @membership = studio.memberships.create membership_params

    redirect_to members_studio_path(@studio)
  end
end

在使当前用户成为所有者后，立即将其添加到

用户

关联中：

def create
  @studio = Studio.new(studio_params)
  @studio.owner = current_user
  @studio.users << current_user

  ...

end

---

有很多：成员，类名：'User'，通过：：memberships

resources :studios do
  member do
    get :members
  end

  resources :memberships, only: [:create, :update, :destroy]
end

def create
  @studio = Studio.new(studio_params)
  @studio.owner = current_user
  @studio.users << current_user

  ...

end

has_many :members, through: :memberships, source: :user
