Javascript - BackboneJS - Backbone.sync覆蓋 - YDN - 異步錯誤

Question

我想與Backbone.sync（）一起使用YDN，但我遇到了«fetchAll»函數的問題。

對於爲例，我已經由此看來

var UserListView = Backbone.View.extend({ 
    el: ".page", 


    initialize: function() { 
     this.users = new UserCollection(); 
    }, 

    render: function() { 
     var that = this; 
     this.users.fetch({ 
      success:function(users){ 
       var template = _.template($('#user-list-template').html(), {users : users.models}); 
       that.$el.html(template); 
      }, 
      error: function(users){ 
       console.log("error"); 
      } 
     })  
    } 
}); 

而且在BackboneSync：

switch (method) { 
    case "read": 
     resp = model.id ? get(model) : all(model); 
     break; 
    case "create": 
     resp = save(model); 
     break; 
    case "update": 
     resp = save(model); 
     break; 
    case "delete": 
     resp = remove(model); 
     break; 
} 

function all(collection) { 
    db.values("users", null, 10).done(function(records) { 
     $.each(records, function(index, val) { 
      collection.add(records); 
     }); 
     return collection; 
    }); 
}; 

我想你知道我被困。 db.values("users", null, 10).done({...});是一種異步方法，例如this.users.fetch({})，在這種情況下，它總是返回錯誤。

你有關於如何處理它的想法嗎？

感謝，

解決：

switch (method) { 
    case "read": 
     model.id ? get(model) : all(model); 
     break; 
    case "create": 
     resp = save(model); 
     break; 
    case "update": 
     resp = save(model); 
     break; 
    case "delete": 
     resp = remove(model); 
     break; 
} 

function all(collection) { 
    console.log("je rentre"); 
    db.values("users", null, 10).done(function(records) { 
     options.success(records);    
    }); 
}; 

和視圖：

var UserListView = Backbone.View.extend({ 
el: ".page", 


initialize: function() { 
    this.users = new UserCollection(); 
}, 

render: function() { 
    var that = this; 
    this.users.fetch({ 
     success:function(users){ 
      console.log(users.models); 
      var template = _.template($('#user-list-template').html(), {users : users.models}); 
      that.$el.html(template); 
     } 
    })  
} 
});
