来自RSpec的意外状态代码

:created 应在何时显示状态 :unprocessable_entity .

  def update
    head :unprocessable_entity unless announcement
    if annnouncement.update(announcement_params)
      render json: annoucement, status: :ok
    else
      render_unprocessable_entity
    end
  end

  def announcement
    Announcement.find(params[id])
  end

announcements\u controller\u规范

it 'fails when announcement does not exists' do
  data = {
    id: 999_999,
    announcement: {
      body: ''
    }
  }.to_json
  post "/api/announcements/#{property.slug}", params: data, headers: headers
  expect(response).to have_http_status(:unprocessable_entity)
end

  1) Api::AnnouncementsController#update fails when announcement does not exists
     Failure/Error: expect(response).to have_http_status(:unprocessable_entity)
       expected the response to have status code :unprocessable_entity (422) but it was :created (201)
