Display the internal array of meteor in the template

Currently, I am working with Meteor and am facing a challenge in accessing values stored within a field that operates as an internal array.

After executing the query (with projection), I receive a single record structured like this:

{ "comments" : [ { "uid" : "1", "un" : "Sarah", "c" : "cc" }, { "uid" : "2", "un" : "Leo", "c" : "dd" } ] }

My objective is to display both the "un" and "c" for each entry in the array within a template. I attempted the following:

Html:

<template name="allComments">
    <ul>
        {{#each allC}}
            <li>{{un}}</li>
        {{/each}}
    </ul>
</template>

JavaScript:

Template.allComments.allC = function () {
    //query that returns result described above
}

I've experimented with {{#with}}, nested {{#each}}, and nested templates without success...

Could someone provide guidance on how to access these values effectively?

Your help is greatly appreciated. Thank you, Sarah.

Answer №1

To improve your JS functionality, consider making the following adjustment:

Template.allComments.helpers({
  allC: function() {
    //implement a query that retrieves the desired result
  }
});

After updating the above code, the '#each' should operate correctly within your template.

Answer №2

Success! I was able to display these comments using:

Template.allComments.helpers({
allC: function () {
    var result=[];
    TasksList.findOne({_id:Session.get('selectedID')})['comments'].forEach(function(entry){
        result.push(entry['un']+entry['c']);
        });
    return result;
    },
});

Additionally, I used:

<template name="allComments">
<ul>
    {{#each allC}}
        <li>{{this}}</li>
    {{/each}}
</ul>
