nAttrMon template helpers
Throughout nAttrMon you can use OpenAF's template functionality (ow.template based on Handlebars) for which nAttrMon registers some Handlebars helpers to access internal nAttrMon data as described on the following table:
| Helper | Usage example | Description |
|---|---|---|
| attr |
{{attr 'Cat/Attr' 'name' 'default'}} {{attr 'Cat/Attr' 'category[0]'}} |

As a second parameter its possible to access a specific entry. As a third parameter its possible to specify a default value in case an attribute value is not found. |
| cval |
{{cval 'Cat/Attr' 'val.region' 'default'}} {{cval 'Cat/Attr' 'val[2].REGION'}} |
Access any current value attribute entry by name (accessing the nattrmon::cvals channel). This will result in a map with: name, val and date. As a second parameter its possible to access a specific entry. As a third parameter its possible to specify a default value in case an attribute current value is not found. |
| lval |
{{lval 'Cat/Attr' 'val.region' 'default'}} {{lval 'Cat/Attr' 'val[2].REGION'}} |
Access any last value attribute entry by name (accessing the nattrmon::lvals channel). This will result in a map with: name, val and date.
