我有一个带有“PagesController”的 Rails4 应用程序。
当找不到页面时,show-method 会引发自定义异常“PageNotFoundError”。
在我定义的控制器之上
rescue_from PageNotFoundError, with: :render_not_found
render not found
是一个私有方法,PagesController
看起来像:
def render_not_found
flash[:alert]=t(:page_does_not_exists, title: params[:id])
@pages = Page.all
render :index, status: :not_found #404
end
开发模式下的 rails-log 显示:
Started GET "/pages/readmef" for 127.0.0.1 at 2013-08-02 23:11:35 +0200
Processing by PagesController#show as HTML
Parameters: {"id"=>"readmef"}
..
Completed 404 Not Found in 14ms (Views: 12.0ms)
所以,到目前为止,它连接了我的 :status => :not_found 作品。
当我做curl -v http://0.0.0.0:3000/pages/readmef
卷曲日志时
curl -v http://localhost:3000/pages/readmef
* About to connect() to localhost port 3000 (#0)
* Trying 127.0.0.1...

< HTTP/1.1 404 Not Found
< X-Frame-Options: SAMEORIGIN
但是使用 RSpec 进行的以下测试失败:
it 'renders an error if page not found' do
visit page_path('not_existing_page_321')
expect(response.status).to eq(404)
within( '.alert-error' ) do
page.should have_content('Page not_existing_page_321 doesn\'t exist')
end
end
1) PagesController renders an error if page not found
Failure/Error: expect(response.status).to eq(404)
expected: 404
got: 200
一切看起来都很好,甚至 test.log 说 404
$ tail -f log/test.log
Started GET "/pages/not_existing_page_321" for 127.0.0.1 at 2013-08-03 09:48:13 +0200

Rendered layouts/_footer.haml (0.6ms)
Completed 404 Not Found in 6ms (Views: 4.5ms)
我尝试了不同的服务器、WebRICK、Thin、独角兽。在开发和生产模式下,一切都按预期工作。即使 test.log 是正确的,但测试失败。
谁能告诉我为什么测试显示 200 而不是 404?
