Question

May be missing something simple, but how can I specify a conditional in Handlebars based on an operation on the object?

Looking to do something like

{{#hasDiscount this}}
  <tr>
    <td>Discount</td>
    <td>{{formatPrice this.Discount}}</td>
  </tr>
{{/hasDiscount}}

With the helper along the lines of

Handlebars.registerHelper 'hasDiscount', (cart) ->
  :runBlock: if cart.Discount > 0

Not sure how to tell it to run the block.

Thanks for any input.

After playing with it found an even simpler way.

{{#if hasDiscount}}
   <tr>
    <td>Discount</td>
    <td>{{formatPrice this.Discount}}</td>
  </tr>
{{/if}}

Because the cart was already the object in the template I could just set the helper like this

Handlebars.registerHelper 'hasDiscount', ->
  true if @Discount > 0
