Rendering Template in Meteor and Iron Router depending on value in document

I am trying to render a template depending on a value of a field in a document.

I tried using a switch case in a helper but the return value comes out incorrect.

units_list.html

<template name="unitsList">
{{#each units}}
  {{> unitItem}}
{{/each}}
</template>

units_list.js

Template.unitsList.helpers({
  units: function() {
    return Units.find({}, {sort: {name: 1}});
  }
});

unit_item.html

<template name="unitItem">
  <a href="{{unitType}}">{{name}}</a>
</template>

unit_item.js

Template.unitItem.helpers({
  unitType: function() {
    var unitType = this.unitType;
    switch(unitType){
      case 'first': return "{{pathFor 'unitPageFirst'}}";
      case 'second': return "{{pathFor 'unitPageSecond'}}";
    }
  }
});

I'm either going about this the wrong way or missing something elementary...

I've cut out a lot of code to focus on the problem.

Any ideas on how to get this working, or any suggestions on how to do it better?

You can't return uncompiled Spacebars strings from JS at execution time.

You can either use Router.path to get the path for your routes within your template helper :

Template.unitItem.helpers({
  unitType: function() {
    var unitType = this.unitType;
    switch(unitType){
      case 'first':
        return Router.path('unitPageFirst', this);
      case 'second':
        return Router.path('unitPageSecond', this);
    }
  }
});

Or you can use plain Spacebars by declaring template helpers to check against the unitType.

HTML

<template name="unitItem">
  {{#if unitTypeIs 'unitTypeFirst'}}
    <a href="{{pathor 'unitTypeFirst'}}">{{name}}</a>
  {{/if}}
  {{#if unitTypeIs 'unitTypeSecond'}}
    <a href="{{pathor 'unitTypeSecond'}}">{{name}}</a>
  {{/if}}
</template>

JS

Template.unitItem.helpers({
  unitTypeIs: function(unitType){
    return this.unitType == unitType;
  }
});

Have a look at Rendering Templates in the Iron-router guide, specifically the this.render('xyz'); statement

https://github.com/iron-meteor/iron-router/blob/devel/Guide.md#rendering-templates
