Meteor display array inside a collection

Question

I want create a posts model, with tags, and be able to display all tags for each post. You know a best way to do it ??

I tried this

<template name='postsLists'>
  {{#each post}}
    {{> postDetails }}
  {{/each}}
</template>


<template name='postDetails'>
  title: {{title}}
  {{#each tag}}
    {{tag}}
  {{/each}}
</template>

Answer 1

You need to use this keyword to get value from an array:

<template name='postDetails'>
  title: {{title}}
  {{#each tag}}
    {{this}}
  {{/each}}
</template>

Answer 2

This code won't work:

{{#each tag}}
  {{tag}}
{{/each}}

because "tag" here refers to both the list and an element in that list. Try:

{{#each tags}}
  {{tag}}
{{/each}}
