Variables and Functions In Templates

[blueprint]

Is there any way of declaring a variable inside a Template?

For example, if I wanted to increment a running counter for records, it would be quite nice if I could do something like:

{{#var counter}}
...
{{counter++}}

Likewise, if I wanted to sum up a number of fields (i.e. a weight field) and then display the total in the Template footer.

Can this be done in the Template (rather than in the Entity as a formula)?

No. Templates very restricted in abilities. The lib we use doesn't give any room for enhancing.

yuri Ok, no problemo.

I think that should work,but if you already have a customview you could just sum up the weights before giving the conext to the template.

 HandleBars.registerHelper("counter",function(root){root.weightSum += this.weight}); 

<table>
{{#each heavyThings}}
{{counter @root}}
<tr><td>{{name}}</td><td>{{weight}}</td><(tr>
{{/each}}
</table>
<footer>
{{weightSum}}
</footer>
