使用 node.js 框架 Meteor -
how come the currentUservariable is definedin a template such as here:
为什么currentUser变量是在模板中定义的，比如这里：
<template name="main_template">
<div class="container">
{{#if currentUser}}
{{> add_player_form_template}}
{{/if}}
</div>
</template>
but when I call currentUserfrom the console, it's undefined:
但是当我currentUser从控制台调用时，它是未定义的：
however, Meteor.userIdis defined:
然而，Meteor.userId定义为：
why is this?
为什么是这样？

{{ currentUser}}is a helper in the main_templatetemplate.
{{ currentUser}}是main_template模板中的帮手。
In your client Javascript you'll need to define that helper method. Something like:
在您的客户端 Javascript 中，您需要定义该辅助方法。就像是：
Template.main_template.helpers({
currentUser: function() {
return Meteor.userId();
}
})

{{ currentUser }}is a template helper that simply calls Meteor.user().
{{ currentUser }}是一个模板助手，只需调用Meteor.user().
In the console, you need to call Meteor.user().
在控制台中，您需要调用Meteor.user().
