我试图理解我何时可以用这个.flush () 在气象应用中。
医生说:
Call inside publish function. Sends all the pending set, unset, and complete messages to the client.
如果我的出版功能是这样的
Meteor.publish( myCollection , function(myid){
return MyCollection.find({_id: myid});
});
我会用这个吗. flush ()?
使用此. flush () 的哪种情况?
Thanks S
在此使用情况下不需要, 因为 Meteor. publish 自动处理如何将 Mongo 光标转换为适合每个订阅客户端的 < code> set 和 unset 命令的细节 。
如果您写一个管理自己的 set 和 unset 的自定义出版物, 您可以使用 flush 将所有尚未更改的更改都推到客户端。 您可以在这里找到一个该技术的示例 : < a href=" https://stackoverflow.com/ queses/ 1056564/ how-does-the- messages-count-example- in- meteor-docs-work > > > > > Meteor docs 的信息计数示例如何工作?
