Question

如何格式化以下行以向/users/1发送请求？

get :show, {format: :json, id: @user1.id }

我尝试过每一种排列和支架安排

结果错误：

NoMethodError:
           undefined method `json' for #<UsersController

整个规范文件：

描述UsersController，：type =＆gt; ：控制器做要求＆＃39; database_cleaner＆＃39;

DatabaseCleaner.strategy = :truncation

describe "GET users" do
    before(:all) do 
        @user1 = FactoryGirl.create :user, name: "Yakov", default_pull_rate: 10, default_push_rate: 9 
        @user2 = FactoryGirl.create :user, name: "Smirnov", default_pull_rate: 15, default_push_rate: 1
        @user1.save
        @user2.save

        @player1 = FactoryGirl.create :player, user_id: 1
        @player1.save
    end

    it "returns all users" do 
        get :index, :format => :json

        expect(response.status).to eq 200

        body = JSON.parse(response.body)
        user_names = body.map { |u| u["name"] } 

        expect(user_names).to match_array(["Yakov", "Smirnov"])

    end

    it "returns player for a user" do 

        get :show, {format: :json, id: @user1.id }

        expect(response.status).to eq 200
    end

    DatabaseCleaner.clean

end

端

控制器：

class UsersController < ApplicationController
    include ActionController::MimeResponds

  def index
    @users = User.all
    respond_to do |format|
        format.json { render json: @users }
    end
  end

  def show
    @user = User.find(params[:id])
    respond_to do |format|
      format.json { render json @user } 
    end
  end

  def create
    @user = PowerUp.new(params[:user])
        @user.save!
  end
end

您的测试工作正常。它实际上向您显示控制器中的问题。

在show行动中，您有

format.json { render json @user }

应该是

format.json { render json: @user }

如何在rspec中测试show方法
