【问题描述】:
我是 ruby on rails 的新手,对于我正在构建的多租户应用程序中最好的下一步是什么感到有点困惑。
基本上我想通过 account_id 来确定资源的范围,所以我在我的 accounts base_controller 中创建了一个名为 current_account 的方法和助手。
但是,我正在关注的教程按子域划分 current_account 的范围,我不想这样做。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 帮助器来定义当前帐户 ID,还是有更好的方法?如果是这样,最好的方法是什么?
背景 第一个注册的用户将成为帐户所有者。然后,帐户所有者可以邀请其他用户加入该帐户。我正在使用设计宝石。资源按帐户划分,因此只有与帐户关联的用户才能看到属于该帐户的记录。
基本控制器
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
帐户模型
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

你看过这颗宝石了吗? github.com/elabs/pundit 它使您能够为您的用户创建策略。我很确定你可以从那里拿走它。

谢谢。看起来它对我有用。我现在要测试一下。
