使用流星js使用基于模板的订阅在Mongo Db中显示单个项目

Question

I don't know what the problem is, i have this snippet to display single items but it does not work as suppose, What's do i make right?

publication file:

Meteor.publish('SingleSchool', function (myslug) {
        check(myslug, String);
        if (!this.userId) {
            throw new Meteor.Error('Not authorized');
            return false;
        } else {
            return SchoolDb.find({slug: myslug});
        }
    })

template base subscription:

Template.view.onCreated(function () {
    var instance = this;
    instance.autorun(function () {
        var slug = FlowRouter.getParam('myslug');
        return Meteor.subscribe('SingleSchool', slug);
    });
});

the route:

FlowRouter.route('/school/:myslug', {
  name: 'view',
  action: function (params) {
    BlazeLayout.render('sidebarschool', {sidebars: 'view'});
  }
})

the template file:

<template name="view">  
    {{#if currentUser}}
    {{#if Template.subscriptionsReady }}
        {{#if SingleSchool}}
            {{#with SingleSchool}}
                <p>{{varibablecalled}}</p>
            {{/with}}
        {{else}}
            <p>Loading...</p>
        {{/if}}
    {{/if}}
</template>

It goes to the slug but no data is displayed for other contents. The slug in the route works fine.

Did you initialize your SingleSchool collection you're trying to read from in the template?

Also, don't forget that this is collection , so you should do SingleSchool.findOne({slug:...}) to obtain needed item.

Btw, your template file looks like messed up: two <template...> tags.
