Rspec和當前用戶ID保存在不同的模型從設計

Question

我正在使用設計來管理用戶和我的目標獲取當前用戶與創建的記錄保存。

當前用戶保存在控制器中，但我的Rspec是錯誤的！

謝謝大家的幫助。

我創型號

class Record < ActiveRecord::Base 
    #Associations 
    belongs_to :user 


    # Validations 
    validates :title, :user, presence: true 
end 

我的記錄控制器

class RecordsController < ApplicationController 
    before_action :find_record, only: [:show, :edit, :update, :destroy] 

    def create 
    @record = Record.new(record_params) 

    if @record.save 
     redirect_to @record 
    else 
     @records = Record.all 
     render 'index' 
    end 
    end 

    def update 
    if @record.update(record_params) 
     flash[:notice] = "The record was updated successfully" 
     redirect_to @record 
    else 
     render 'edit' 
    end 
    end 

    private 

    def find_record 
     @record = Record.find(params[:id]) 
    end 

    def record_params 
     params.require(:record).permit(:title, :description, :user_id).merge(user: current_user) # as suggested 
    end 
end 

我Rspec的

require 'rails_helper' 

describe RecordsController do 
    let(:record) { create(:record) } 
    let(:user) { create(:user) } 
    let(:title) { "Some title I would like to put in my record" } 
    let(:description) { "description I would like to put in my record" } 


    describe "#create" do 
    it "creates a new record with the given title and description" do 
     expect do 
     post :create, record: { title: title, description: description, user_id: user } 
     end.to change { Record.count }.by(1) 

     expect(response).to redirect_to(assigns[:record]) 

     expect(assigns[:record].title).to eq(title) 
     expect(assigns[:record].description).to eq(description) 
    end 

    it "fails to create a record and returns to the index page" do 
     expect(post :create, record: { description: description }).to render_template(:index) 
     expect(assigns[:records]).to eq(Record.all) 
    end 
    end 

    describe "#update" do 
    it "find the records and sets the new given values" do 
     put :update, { id: record.id, record: { title: title, description: description } } 

     record.reload 
     expect(record.title).to eq(title) 
     expect(record.description).to eq(description) 

     expect(flash[:notice]).to eq("The record was updated successfully") 
    end 

    it "fails to create a record and returns to the edit page" do 
     expect(put :update, { id: record.id, record: { title: "" } }).to render_template(:edit) 
    end 
    end 
end 

現在與當前用戶正在保存Rspec的拋出了我在錯誤的創建和更新：

Answer 1

您需要先登錄用戶，然後才能使用current_user。 喜歡的東西：

before do                  
    sign_in :user, create(:user) 
end
