FlowRouter 没有在单独的模板中定义

FlowRouter is not defined in individual templates

使用 Meteor,我从一个默认的 Meteor 项目开始......

meteor create --full

我在router.js中添加了一条路线,像这样:

FlowRouter.route('/group/:_id', {
  name: 'App.groups.show',
  action() {
    if (!logged_in()) {
      FlowRouter.go("App.home");
    }
    else {
      this.render('App_body', 'Group');
    }
  },
});

router.js 在这里:

/imports/startup/client/router.js

群组模板是这样的:

<template name="Group">
  
  {{> user_group}}

</template>

对于 user_group,我有这个:

Template.user_group.onCreated(function user_groupOnCreated() {
  console.log("id", FlowRouter.getParam('_id'));
});

这导致:

ReferenceError: FlowRouter is not defined
    at Blaze.TemplateInstance.user_groupOnCreated (user-group.js:46)
    at template.js:119
    at Function.Template._withTemplateInstanceFunc (template.js:490)
    at fireCallbacks (template.js:115)
    at Blaze.View.<anonymous> (template.js:195)

    at view.js:273
    at Object.Blaze._withCurrentView (view.js:533)
    at Object.Blaze._fireCallbacks (view.js:272)

我也无法在我的模板中访问 FlowRouter.go

我错过了什么?

您需要在每个主动使用它的 js 中导入 FlowRouter(在您的示例中为模板):

import { FlowRouter } from 'meteor/kadira:flow-router'

Template.user_group.onCreated(function user_groupOnCreated() {
  console.log("id", FlowRouter.getParam('_id'))
})
