How to publish single objects seems not clear enough to me. Please what's the best way to handle this. This code snippet does not display anything on the view.
Helper file
singleSchool: function () {
if (Meteor.userId()) {
let myslug = FlowRouter.getParam('myslug');
var subValues = Meteor.subscribe('SingleSchool', myslug );
if (myslug ) {
let Schools = SchoolDb.findOne({slug: myslug});
if (Schools && subValues.ready()) {
return Schools;
}
}
}
},
Publish file
Meteor.publish('SingleSchool', function (schoolSlug) {
check( schoolSlug, Match.OneOf( String, null, undefined ) );
user = Meteor.users.findOne({_id:this.userId})
if(user) {
if(user.emails[0].verified) {
return SchoolDb.findOne({ slug: schoolSlug, userId: {$lt: this.userId}});
} else {
throw new Meteor.Error('Not authorized');
return false;
}
}
});
template file
<template name="view">
{{#if currentUser}}
{{#if Template.subscriptionsReady }}
{{#with singleSchool}}
{{singleSchool._id}}
{{singleSchool.addschoolname}}
{{/with}}
{{/if}}
{{/if}}
</template>
As you said "This code snippet does not display anything on the view." well, inside Meteor.publish
you need to return cursor
, not array
or any other object
.
So use this code:
Meteor.publish('SingleSchool', function (schoolSlug) {
check( schoolSlug, Match.OneOf( String, null, undefined ) );
var user = Meteor.users.findOne({_id:this.userId});
if(!user || !user.emails[0].verified) {
throw new Meteor.Error('Not authorized');
}
return SchoolDb.find({ slug: schoolSlug, userId: {$lt: this.userId}},{limit:1});
});
