레일 4의 컨트롤러에서 술어 메서드를 호출하는 방법은 무엇입니까?

나는 레일에 새로운 오전 숨김으로 플래그에 대한 경로를 과정을 호출 할 수있게 되었 할 RSpec에 다음과 같은 비트를 얻기 위해 노력하고 있어요 :레일 4의 컨트롤러에서 술어 메서드를 호출하는 방법은 무엇입니까?

describe 'PATCH hide_course' do 
    before :each do 
     @course = create(:course) 
    end 

    it 'marks the course as hidden' do 
     patch :hide_course, id: @course 
     expect(@course.reload.hidden?).to be_true 
    end 

    it 'redirects to courses#index' do 
     patch :hide_course, id: @course 
     expect(response).to redirect_to course_url 
    end 
end

내가 다음 문제없이 다음과 같은 경로를 설정합니다

resources :courses 
put '/courses/:id/hide_course', to: 'courses#hide_course'

내 문제는 컨트롤러 동작을 설정하는 것입니다.

def hide_course 
    @course = Course.find(params[:id]) 
    @course.hide 
end 

private 

def course_params 
    params.require(:course).permit(:name,:description,:department,:hidden, 
     :lecture_attributes => [:name,:description,:level]) 
end

내 모델은 다음과 같습니다 :

def hide 
    update!(:hidden => true) 
end

나 레일 4에서이 방법을 설정하는 최선의 방법은 무엇입니까 여기가 내 CoursesController에 쓴 비트는? 내 스키마에도 존재하지 않는 숨겨진 속성에 대한 오류가 계속 발생합니다. 감사!

속성에'? '기호가 왜 숨겨져 있습니까? 귀하의 속성 이름이 '숨김'임을 알 수 있습니다. –

좋은 질문입니다. Rspec을 사용한 Everyday Rails 테스팅의 예제에서 벗어나려고했습니다. 그것은 내가 알 수없는 특성 오류를 제거하는 경우에도 줄 것? – Coherent

플래그/부울 속성의'?'는 속성이 플래그임을 나타내는 규칙이며,'if's 및'unless'에 대한 설탕을 제공합니다. – rafb3

필자는 테스트 데이터베이스를 자동으로 관리하는 레일 4.2를 실행 중입니다. (적어도 그 명령을 실행할 때 나는 경고입니다). 나는 rspec을 사용하여이 프로젝트에서 아무 문제없이 일반적인 모델 스펙을 코딩 했으므로 테스트 db가 괜찮다고 생각한다. 감사! – Coherent
