Ruby Rails - 资源范围 current_account

Question

我是 rails 上 ruby 的新手，我对我正在构建的多租户应用程序的最佳下一步是什么有点困惑。

基本上我想通过 account_id 来限定资源范围，所以我在我的帐户 base_controller.

中创建了一个名为 current_account 的方法和助手

但是，教程中我关注的范围 current_account 是我不想做的子域。所以我需要一种方法来识别当前用户的account_id，这样我就可以拥有一个资源变量@contact = current_account.contacts."all".

我是否需要在用户和帐户模型之间建立新的关联，以便我可以使用 current_user 助手来定义当前帐户 ID，或者是否有更好的方法？如果是这样，最好的方法是什么？

背景第一个注册的用户成为帐户所有者。然后帐户所有者可以邀请其他用户加入该帐户。我正在使用这个装置 gem。资源按帐户划分范围，因此只有链接到帐户的用户才能看到属于该帐户的记录。

基地控制器

module Accounts
  class BaseController < ApplicationController
    def current_account
      @current_account ||= ?????
    end
    helper_method :current_account

    def owner?
      current_account.owner == current_user
    end
    helper_method :owner?
  end
end

联系人（我的资源）控制器

module Accounts
  class ContactsController < Accounts::BaseController
    def index
        @contact = current_account.contacts.all
    end
  end
end

账户模型

class Account < ActiveRecord::Base
  belongs_to :owner, class_name: "User"
  accepts_nested_attributes_for :owner

  validates :subdomain, presence: true, uniqueness: true

  has_many :contacts
  has_many :invitations
  has_many :memberships
  has_many :users, through: :memberships
end

邀请模型

class Invitation < ActiveRecord::Base
  belongs_to :account
  validates :email, presence: true
end

会员模式

class Membership < ActiveRecord::Base
  belongs_to :account
  belongs_to :user
end

用户模型

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
end

路线

Rails.application.routes.draw do
  devise_for :users
  scope module: "accounts" do
  resources 'dashboard'
  resources 'contacts'
  resources :invitations, only: [:new, :create] do 
    member do
      get :accept
      patch :accepted
    end
  end
  resources :users, only: [:index, :destroy]
end

架构

ActiveRecord::Schema.define(version: 20170124002015) do

  create_table "accounts", force: true do |t|
    t.string   "name"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "owner_id"
    t.string   "subdomain"
  end

  add_index "accounts", ["subdomain"], name: "index_accounts_on_subdomain"

  create_table "contacts", force: true do |t|
    t.string   "first_name"
    t.string   "last_name"
    t.string   "phone"
    t.string   "email"
    t.text     "comments"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "account_id"
  end

  add_index "contacts", ["account_id"], name: "index_contacts_on_account_id"

  create_table "invitations", force: true do |t|
    t.string   "email"
    t.integer  "account_id"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "token"
  end

  add_index "invitations", ["account_id"], name: "index_invitations_on_account_id"
  add_index "invitations", ["token"], name: "index_invitations_on_token"

  create_table "memberships", force: true do |t|
    t.integer  "account_id"
    t.integer  "user_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "memberships", ["account_id"], name: "index_memberships_on_account_id"
  add_index "memberships", ["user_id"], name: "index_memberships_on_user_id"

  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"
  end

  add_index "users", ["email"], name: "index_users_on_email", unique: true
  add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true

end

Answer 1

用户和帐户之间有两种可能的关联：

用户有多个账户
用户属于一个帐户

第一种情况，无法从current_user设置租户，因为不清楚应该使用哪个帐户作为当前租户。 schema.rb 中的成员资格 table 表示这是您提到的教程采用的方法。按子域加载帐户有助于指定应将哪个帐户用作当前租户。

在第二种情况下，每个用户只有一个帐户。用户获得 account_id，成员资格 table 已过时，您可以像这样加载当前租户：

def current_account
  @current_account ||= current_user.account
end

Do I need to make a new association between the user and account model so that I can use the current_user helper to define the current account id or is there a better way? If so, what is the best way to do this?

在我看来，您想采用第二种方法，这需要一个帐户 has_many 个用户和一个用户 belongs_to 个帐户。
