BackboneJS는 PUT 대신 GET 보내기를 저장합니다.

Question

model.save() 메서드를 호출하면 My BackboneJS 모델에서 PUT 대신 GET을 전송합니다. REST API를 위해 장고 티맥 (django-tastypie)이있는 장고 백엔드가 있습니다.

예를 들어, 나는 다음과 같이 업데이트하려고 사용자 모델이 있습니다

var me = new UserModel({ 
    id: this.user.id 
}); 
me.fetch({ 
    success: function (t) { 
     console.log(t); 
     t.set({ 
      'premium': true 
     }); 
     t.save({ 
      success: function() { 
       alert('success') 
      }, 
      error: function (m, e) { 
       console.log(e); 
      } 
     }); 
    } 
}) 

를 I 콘솔에서 다음과 같은 오류 얻을 :

GET http://127.0.0.1:8000/api/v1/users/100003258103084/ 500 (INTERNAL SERVER ERROR) 

내가 t.save()이있는 줄을

내가 여기서 잘못하고있는 것이 있습니까?

좋아, 그가 라인 console.log(e)은 다음과 같다하는 int 보여줍니다 메시지 :이 문제가 장고 - Tastypie과하지 BackbonejS와 것을 의미합니까

? 아직도이 GET은 내가 추측하는 문제입니다!

Answer 1

save 메소드는 두 개의 인수를 취합니다. model.save ([attributes], [options]) - 둘 다 선택 사항입니다.

지금은 속성 대신 옵션 해시를 전달합니다. 시도 :

t.save(t.attributes, { 
    success: function() { 
     alert('success') 
    }, 
    error: function (m, e) { 
     console.log(e); 
    } 
}); 

또는

t.save({'premium':true}, { 
    success: function() { 
     alert('success') 
    }, 
    error: function (m, e) { 
     console.log(e); 
    } 
}); 

Answer 2

me.fetch 요청을 GET 보내는 것 같다. 기본 동기화 방법을 재정의하지 않으면 Backbone에 저장시 GET 요청을 발행 할 수있는 것이 없습니다.

저장은 POST 또는 PUT 요청 만 수행합니다 (모델에 ID 및 PUT이없는 경우 POST).
