Rails的ActionController的參數錯誤

Question

這是我在users_controller.rb創建方法

def create 
@user = User.new(user_params) 

respond_to do |format| 
    if @user.save 
    format.html { redirect_to users_url, notice: 'User was successfully created.' } 
    format.json { render :show, status: :created, location: @user } 
    else 
    format.html { render :new } 
    format.json { render json: @user.errors, status: :unprocessable_entity } 
    end 
end 
end 

private 
    def set_user 
    @user = User.find(params[:id]) 
    end 

    def user_params 
    params.require(:user).permit(:name, :password, :password_confirmation) 
    end 

末

，這是我Users_controllers_spec.rb文件

require 'rails_helper' 

RSpec.describe UsersController, type: :controller do 

    describe "Post /create" do 
    let(:user){build(:user)} 
    it "should create user" do 
    expect(User).to receive(:new).with({name: 'Naik', password: 'secret', password_confirmation: 'secret'}).and_return(User) 
    post :create, user: {name: 'Naik', password: 'secret', password_confirmation: 'secret'} 
    expect(flash[:success]).to eq("User was successfully created.") 
    expect(response).to redirect_to(users_path) 
    end 
    end 
end 

這是我的錯誤獲得。我錯過了什麼嗎？我是Rspec測試新手，所以如何解決它的任何建議，將不勝感激。

謝謝。

Answer 1

這似乎是使用Rails 5.這裏只當是一個問題在這可怎麼固定：How to expect a Params hash in RSpec in Rails 5?

基本上，這應該是：

expect(User).to receive(:new).with(ActionController::Parameters.new(name: 'Naik', password: 'secret',password_confirmation: 'secret').permit(:name, :password, :password_confirmation)).and_return(user) 
expect(user).to receive(:save).and_return(true) # stub the `save` method 
post :create, user: {name: 'Naik', password: 'secret', password_confirmation: 'secret'} 
# ...and then your expectations 

Answer 2

您可以在ActionController::Parameters上做to_h。然後，所有允許的參數將在哈希：

params = ActionController::Parameters.new({ 
    name: 'Senjougahara Hitagi', 
    oddity: 'Heavy stone crab' 
}) 
params.to_h # => {} 

safe_params = params.permit(:name) 
safe_params.to_h # => { name: 'Senjougahara Hitagi' } 

我不是RSpec的親，但我認爲你可以這樣做：

expect(controller.params.to_h).to be({...})
