无法通过Post在Rspec中创建模型

我正在尝试在Rspec中创建一个用户：

require "rails_helper" RSpec.describe UsersController, type: :controller do describe "POST #index" do it 'should create a user' do post :create, {name: "name1", age: 25}.to_json, format: :json # ............. 

但我每次都会收到validation错误： name can't be blank, age can't be blank

UserController接受json：

  def create @user = User.new(params1) if @user.save render json: @user else render json: @user.errors, status: :unprocessable_entity end end def params1 params.permit(:id, :name, :age) end 

Answer 1

发送给create的参数不应该是json String而是Hash。

从rspec文档 ：

 require "rails_helper" RSpec.describe WidgetsController, :type => :controller do describe "responds to" do it "responds to custom formats when provided in the params" do post :create, { :widget => { :name => "Any Name" }, :format => :json } expect(response.content_type).to eq "application/json" end end end 

所以你的测试应该是：

 require "rails_helper" RSpec.describe UsersController, type: :controller do describe "POST #create" do it 'should create a user' do post :create, { user: {name: "name1", age: 25}, :format => :json } ...
