流星光纤问题？

Question

我拉一个CSV，解析成一个数组（很好），并试图填充Mongo集合（失败）。

我在终端中出现以下错误：“错误：流星代码必须始终在光纤内运行，尝试使用Meteor.bindEnvironment传递给非流星库的回调。

这是我的js代码（服务器）：

var order, orders, _i, _len; 

CSV().from(fileAddress).to.array(function(data) {}); 

orders = data; 

for (_i = 0, _len = orders.length; _i < _len; _i++) { 
    order = orders[_i]; 
    Orders.insert({ 
    clientId: order[0], 
    shipmentId: order[1], 
    orderId: order[2], 
    orderDate: order[3], 
    expectedDeliveryDate: order[4], 
    shipMethod: order[5], 
    customerName: order[6], 
    companyName: order[7], 
    address1: order[8], 
    address2: order[9], 
    city: order[10], 
    state: order[11], 
    zipCode: order[12], 
    country: order[13], 
    itemId: order[14], 
    quantity: order[15], 
    sku: order[16], 
    itemDescription: order[17], 
    productVariationDetails: order[18], 
    artfile: order[19], 
    customerMessage: order[20] 
    }); 
} 

如果你愿意的话，你可以看到CoffeeScript的还有：

CSV().from(fileAddress).to.array (data) -> 
     orders = data 
     for order in orders 
      Orders.insert({ 
       clientId: order[0], 
       shipmentId: order[1], 
       orderId: order[2], 
       orderDate: order[3], 
       expectedDeliveryDate: order[4], 
       shipMethod: order[5], 
       customerName: order[6], 
       companyName: order[7], 
       address1: order[8], 
       address2: order[9], 
       city: order[10], 
       state: order[11], 
       zipCode: order[12], 
       country: order[13], 
       itemId: order[14], 
       quantity: order[15], 
       sku: order[16], 
       itemDescription: order[17], 
       productVariationDetails: order[18], 
       artfile: order[19], 
       customerMessage: order[20] 
       })

我试图使用流星绑定环境如下所述。这是当前的状态：

我打电话使用用户的服务器方法所触发模板事件：

Template.upload.events 
    'click #runMethod':() -> 
     Meteor.call('csv2Array', Session.get("fileUrl"), (error, result) -> 
      console.log result[0]) 

在服务器上，方法如下：

Meteor.methods 
    'csv2Array': (fileUrl) -> 
     data = CSV().from(fileUrl).to.array Meteor.bindEnvironment((data) -> 
      console.log data[0], (error) -> 
       console.log "Error in bindEnvironment", error) 

当我运行该方法，我得到这个错误：

解决方案是Meteor.bindEnvironment：

var order, orders, _i, _len; 

CSV().from(fileAddress).to.array(
    Meteor.bindEnvironment(
     function(data) { 
      orders = data; 
      for (_i = 0, _len = orders.length; _i < _len; _i++) { 
       order = orders[_i]; 
       Orders.insert({ 
       clientId: order[0], 
       //... 
       customerMessage: order[20] 
       }) 
      } 
     }, 
     function(error) { 
      console.log('Error in bindEnvironment:', error); 
     } 
    ) 
);
