Question

我想测试这个update操作：

  def update
    @player = Player.find(params[:id])
    begin
      @player.update_attributes(player_params_avatar)
      flash[:success] = "Avatar updated"
      redirect_to player_path(@player)
    rescue ActionController::ParameterMissing => e
      flash[:danger] = "First choose avatar file"
      redirect_to :back
    end
  end

def player_params_avatar
  params.require(:player).permit(:avatar)
end

我正在考虑类似的事情：

  describe "PUT #update" do
    let!(:player1) { FactoryGirl.create :player }
    context "when data is valid" do
      it "update avatar" do
        avatar = File.new(Rails.root + 'spec/factories/images/1.png') 
        put :update, player: { id: player1.id, avatar: avatar }
        expect(flash[:success]).to be_present
      end
    end

但在RSpec控制台中我收到错误：

 Failure/Error: put :update, player: { id: player1.id, avatar: avatar }
 ActionController::UrlGenerationError:
   No route matches {:action=>"update", :controller=>"players", :player=>{:id=>"1", :avatar=>"#<File:0xaed5b84>"}}

为什么此代码会出现此错误？有特定的玩家id所以也应该是正确的网址，例如。

http://localhost:3000/players/1/edit

编辑：我正在使用paperclip gem作为头像。

我的routes文件：

Rails.application.routes.draw do
  get 'pages/about'
  get 'matches/new'

  root 'pages#home'

  resources :players
  resources :matches

  get '*path' => redirect('/')
end

我自己解决了这个问题。

棘手的问题是：

put :update, player: { id: player1.id, avatar: avatar }

我把它改为：

put :update, id: player1.id, player: { avatar: file }

测试通过。
