我最近将一个项目从 MongoDB/mongoid 转换为 PostgreSQL。过渡后，我的所有模型规格都通过了，并且大多数控制器规格都通过了。我的三个控制器没有通过测试。
根据以下模型定义，警报、订单和用户模型取决于客户和债务人模型：
class Client < ActiveRecord::Base
has_many :users, autosave: true, dependent: :destroy
has_many :alerts, autosave: true, dependent: :destroy
has_many :orders, autosave: true, dependent: :destroy
...
end
class Debtor < ActiveRecord::Base
has_many :orders, autosave: true
has_many :alerts, autosave: true
...
end
class Alert < ActiveRecord::Base
belongs_to :client
belongs_to :debtor
...
end
class Order < ActiveRecord::Base
belongs_to :client
belongs_to :user
belongs_to :debtor
...
end
class User < ActiveRecord::Base
rolify
devise :database_authenticatable,
:recoverable, :rememberable, :trackable, :validatable
has_and_belongs_to_many :roles, :join_table => :users_roles
belongs_to :client
has_many :orders
end
几乎所有失败的测试都有相同的错误（有些有“找不到带有 id= 的客户端”）：
129) OrdersController logged in as a regular user GET #new renders the new template
Failure/Error: get :new, client_id: @user.client_id
ActiveRecord::RecordNotFound:
Couldn't find Debtor with id=
# ./spec/controllers/orders_controller_spec.rb:59:in `block (4 levels) in <top (required)>'
我已经运行了 db:test:prepare 和 drop、create、migrate 序列。
更新：这是来自 orders_controller_spec.rb 和相关控制器的相关规范。我是一个 rspec 菜鸟，所以如果before(:each)封锁是反人类罪，我现在道歉。
require 'spec_helper'
describe OrdersController do
before (:each) do
@user, @user2, @user3, @admin = FactoryGirl.create(:user), FactoryGirl.create(:user), FactoryGirl.create(:user), FactoryGirl.create(:user)
@client, @client2 = FactoryGirl.create(:client), FactoryGirl.create(:client)
@debtor, @debtor2, @debtor3 = FactoryGirl.create(:debtor), FactoryGirl.create(:debtor), FactoryGirl.create(:debtor)
@order, @order2, @order3, @order4 = FactoryGirl.create(:order), FactoryGirl.create(:order), FactoryGirl.create(:order),FactoryGirl.create(:order)
@role = FactoryGirl.create(:role)
@admin_role = FactoryGirl.create(:admin_role)
@vip_role = FactoryGirl.create(:vip_role)
@user.roles << @role
@user2.roles << @vip_role
@user3.roles << @role
@admin.roles << @admin_role
@client.users << @user << @admin
@client.orders << @order << @order2
@client2.users << @user2 << @user3
@client2.orders << @order3 << @order4
end
context "logged in as a regular user" do
before { sign_in @user }
describe "GET #index" do
before { get :index, client_id: @user.client_id }
it "assigns a list of orders belonging to user client" do
assigns(:orders).to_a.should eq([@order, @order2])
end
it "renders the :index template" do
response.should render_template :index, client_id: @user.client_id
end
end
describe "GET #show" do
context "for order belonging to user client" do
before { get :show, client_id: @user.client_id, id: @order }
it "assigns the requested order to @order" do
assigns(:order).should eq(@order)
end
it "renders the :show template" do
response.should render_template :show, client_id: @user.client_id, id: @order
end
end
context "for order not belonging to user client" do
before { get :show, client_id: @client2.id, id: @order3 }
it "redirects to the home view" do
response.should redirect_to root_url
end
end
end
describe "GET #new" do
it "renders the new template" do
get :new, client_id: @user.client_id
response.should render_template :new, client_id: @user.client_id
end
end
...
end
end
相关的控制器动作：
class OrdersController < ApplicationController
before_filter :authenticate_user!
before_filter :load_client
before_filter :has_enough_units, :only => [:create]
respond_to :html
load_and_authorize_resource :debtor
load_and_authorize_resource :order, :through => :client, :shallow => true
def index
if @client == nil
@orders = Order.all
else
@orders = @client.orders.all
end
respond_with(@orders)
end
def show
if @client == nil
@order = Order.find(params[:id])
else
@order = @client.orders.find(params[:id])
end
end
def new
if current_user.has_role? :admin
@order = Order.new
else
@order = @client.orders.build
end
@order.build_debtor
@clients = Client.all.to_a
end
...
end
希望这是足够的信息......
