覆盖backbone.sync只为认沽 [英] override backbone.sync only for put

问题描述

有没有办法从数据库覆盖 PUT 响应同步法和排除 ID 字段的任何可能的方式，而其余的一样吗？我使用的原料药Django的REST框架;尝试 PUT ，我收到：

  {field_errors：ID：此字段不存在]}
 

我想，如果我重写同步和排除 ID 字段 PUT ，我的问题将得到解决，但我不知道该怎么做。

解决方案

  Backbone._sync = Backbone.sync;
Backbone.sync =功能（方法，模型，期权）{
VAR PARAMS = _.clone（选件）;
删除model.attributes.id;
params.success =函数（模型）{
    如果（options.success）options.success（模型）;
};
params.error =函数（模型）{
    如果（options.error）options.error（模型）;
    };
Backbone._sync（方法，模型，则params）;
}
 

Is there any possible way to override the sync method for PUT response and exclude the id field from db, and remaining the same? I am using the Django REST framework for APIs; while trying to PUT, I'm getting:

{"field_errors": "id": ["This field does not exist."],} 

I think if I override sync and exclude the id field for PUT, my problem will be solved, but I don't know how to do it.

解决方案

Backbone._sync = Backbone.sync;
Backbone.sync = function(method, model, options) {
var params = _.clone(options);
delete model.attributes.id;
params.success = function(model) {
    if(options.success) options.success(model);
};
params.error = function(model) {
    if(options.error) options.error(model);
    };
Backbone._sync(method, model, params);
}
