How to show a simple value from a meteor collection in a meteor template?
Question
I want to display an object from a collection in meteor using handlebars.
I have this example about what I have:
Collection: Transactions.
Server side:
Meteor.publish('getTransaction', function(transactionid){
return Transactions.findOne({transactionid:transactionid});
});
Client side:
HTML
<template name='MainTransac'>
<body>
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title" align="center">General information</h3>
</div>
<div class="panel-body">
<table class="table table-striped">
<tbody>
<tr>
<td>TransactionID:</td>
</tr>
<tr>
<td>{{transactionid}}</td>
</tr>
</tbody>
</table>
</div>
</div>
</body>
</template>
JS
Template.MainTransac.onCreated(function(){
this.subscribe('getTransaction',Router.current().params.transactionid);
});
As you can see I have receiving the trasactionid from another page. But I am not able to know how can I show the table with the transaction id or any other field from the transaction document.
I really appreciate all your help about it.
If you have any question just let me know, have a great day.

As first you have to create a helper which will contains your collection data:
Template.MainTransac.helpers({
transaction: function(){ return Transactions.find(); }
});
Then you will be able to include that helper in your template:
<tbody>
<tr>
<td>TransactionID:</td>
</tr>
<tr>
{{#with transaction}}
<td>{{transactionid}}</td>
{{/with}}
</tr>
</tbody>
Hope it works !

A publication must return a cursor or an array of cursors . You have:
Meteor.publish('getTransaction', function(transactionid){
return Transactions.findOne({transactionid:transactionid});
});
which is returning an object.
Just change the .findOne() to .find()
Meteor.publish('getTransaction', function(transactionid){
return Transactions.find({transactionid:transactionid});
});
Then your publish() will work as will your subscribe() . You still need to select the right data context for your template via a template helper.
