ArgumentError - 测试显示控制器方法时参数数量错误（2表示1）

Question

我正在尝试为控制器的show方法编写测试。

以下是方法：

def show
  if current_user
    goal= Goal.find_by_name(params[:id], :include => :projects, :conditions => ['projects.flag = true OR projects.user_id = ?', current_user.id])
  else
    goal= Goal.find_by_name(params[:id], :include => :projects, :conditions => ['projects.flag = true'])
  end

  @results = goal.projects if goal
end

这是我到目前为止的测试：

describe '#show' do
  before :each do
    @user = FactoryGirl.create(:user)
    @project= FactoryGirl.create(:project, user: @user, flag: 1)
    @goal= FactoryGirl.create(:goal, name: 'goal')
    @goal_association= FactoryGirl.create(:goal_association, goal_id: @goal.id, project_id: @project.id)
    controller.stub(:current_user).and_return(@user)
  end

  it 'search by goal' do
    get :show, id: @goal.name

    expect(response.status).to eq 302
  end
end

此测试返回以下错误：

 Failure/Error: get :show, id: @goal.name
 ArgumentError:
   wrong number of arguments (2 for 1)

错误指向goal= Goal.find_by_name(params[:id], :include => :projects, :conditions => ['projects.flag = true OR projects.user_id = ?', current_user.id])线。

我不知道如何解决这个问题。任何关于此的线索都会有所帮助。

Answer 1

你应该使用最新的语法，因为我假设你没有使用这个真正老的2.3 Rails版本。我建议像这样：

scope = if current_user
          Goal.joins(:projects).where('projects.flag = true OR projects.user_id = ?', current_user.id)
        else
          Goal.joins(:projects).where(projects: { flag: true })
        end
goal = scope.find_by(name: params[:id])
