Question

我正在尝试在后台从我的节点应用程序增加“view_amount”的值，但它只有一半的时间才会工作。另一半，我得到这个错误：

[Error: set]

这是我的代码（Coffeescript）：

@ref.firebaseClient.child('listings').child(val.listing_id).child("view_amount").transaction (current_value) ->
  (current_value || 0) + 1
, (error, committed, snapshot) ->
  if error
    console.log error

这就是我设置它的路径：

{
  "headline" : "Yeezy Boost 750",
  "shoe_size" : 9.5,
  "short_url" : "K5wv",
  "size_type" : "men",
  "status" : "active",
  "style_code" : "BB1840",
  "timestamp" : 1467842400000,
  "view_amount" : 3043,
  "watching_amount" : 2
}

什么可能导致交易代码失败？我是否有可能在特定路径上每秒运行一次交易次数太多？如果我在运行事务的同时更改“style_code”，事务是否会失败？

更新：这是我在Node工作中遇到的错误。我发现“设置”错误非常混乱，因为我正在尝试在路径“view_amount”上执行事务。我决不在那条路上做“设定”。

Answer 1

对于错误的错误消息表示歉意，但此错误表示您在相关路径（set()上方，上方或下方的任何内容）上执行了update()或/listings/<val.listing_id>/view_amount操作交易已完成，因此我们取消了该交易，因为我们不知道我们是否应该在set()之前重新启动交易，或者set()是否应该覆盖交易＆＃39; s写等等。

通常，您需要注意不要在数据库的同一部分混合set()和transaction()次调用。
