BackboneJS保存發送GET而不是PUT

Question

當我調用model.save()方法時，我的BackboneJS模型現在發送一個GET而不是PUT。 我有一個Django後端與django-tastypie的REST api。

例如，我有嘗試更新這樣一個用戶模型：

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); 
      } 
     }); 
    } 
}) 

我在控制檯中出現以下錯誤：

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

在那裏我有t.save()行

有什麼我在這裏做錯了嗎？

編輯

好吧，它顯示詮釋他的線console.log(e)是如下消息：

這是否意味着問題出在Django的Tastypie而不是與BackbonejS？仍然這GET是我猜的問題！

Answer 1

save方法需要2個參數：model.save（[attributes]，[options]） - 都是可選的。

現在您正在傳遞選項散列而不是屬性。嘗試：

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

或

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

Answer 2

似乎me.fetch發送GET請求。 Backbone中沒有任何東西會在保存時發出GET請求，除非您已覆蓋默認的同步方法。

只保存POST或PUT請求（如果模型沒有ID和PUT，則POST）否則。
