使用 Rails 中的 Devise 将帐户 ID（父级）传递给用户（子级）

Question

我已经设置了必要的模型和视图来拥有一个设计资源、帐户和用户。帐户 has_many users & User belongs_to account。架构将 account_id 反映为用户的属性。我可能弄错了，但我的印象是，当帐户登录并创建新用户时，此 account_id 属性会自动填充。检查 Rails 控制台后，似乎所有以这种方式创建的新用户的 account_id 值为 nil。单独的问题，但这是在使用 Devise 的应用程序中实现多租户的理想方式吗？

型号：

用户.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  belongs_to :account, :inverse_of => :users   
  accepts_nested_attributes_for :account
end

account.rb

class Account < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  has_many :users, :inverse_of => :account, :dependent => :destroy  
  accepts_nested_attributes_for :users
  has_many :projects

end

schema.rb（仅用户和帐户）

create_table "users", force: true do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "account_id"
    t.boolean  "supervisor"
    t.string   "name"
  end
create_table "accounts", force: true do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "name"
  end

    def new     
        @user = User.new

    def create         
      @user.skip_confirmation! # confirm immediately--don't require email confirmation     
      if @user.save

        redirect_to users_path # list of all users     
      else       
        render 'new'     
      end   
    end

    def index
        @users = User.all
    end

    @account = Account.new(params[:account])     
    if @account.save       
      flash[:success] = "Account created"       
      redirect_to accounts_path

Answer 1

我不确定您究竟想如何创建用户

但是用

创建一个用户

@account.users.build

会自动将 account_id 添加到用户对象。

希望这会有所帮助！ :)
