Rails 3.1 + Heroku : 누군가가이 Heroku 로그를 해독하도록 도와 줄 수 있습니까?

Question

내 클라이언트가 Heroku에서 내 Rails 서버에 대한 단일 HTTP 요청에서 여러 JSON 응답을받는 (간혹 발생하는) 간헐적 인 문제가 발생했습니다. 여기에 내가 레일 및 Heroku가에 새로 온 문제를 보여주는 Heroku가 로그 ...

, 그래서 꽤 무슨 일이 일어나고 있는지 알아 내기 위해 충분한이 로그를 이해할 수 없습니다. Heroku의 Rails 응용 프로그램이 내 클라이언트로부터 여러 HTTP 요청을 수신합니까? 아니면 하나의 HTTP 요청 만 받고 여러 개의 JSON 응답을 반환합니까?

미리 감사드립니다.

나는이 같은 문제를 했어이 가끔 - 자바 스크립트 내가 한 번만 해고를 의미 할 때 거품까지 DOM과 여러 번 발생하도록 요청 . 이로 인해 서버가 매우 빨리 중단 될 수 있으므로 앱을보고 신속하게 AJAX 호출을 실행하지 않아야합니다.

이것을 쉽게 잡을 수있는 방법은 AYAX 호출 직전 또는 직후에 alert()을 넣고 발동 횟수와 예상 횟수를 확인하는 것입니다.

나는 그것이 당신의 문제인지는 모르겠지만, 전에 그런 일이 일어났습니다.
