JCR SQL 2 Query - HandlebarsException

[bona]

I'm attempting to construct a query to retrieve assets based on a selected JCR node type. I'm attempting to compare the nodeType variable within the following condition.

I have added condition:
{{#if '{{nodeType}}' == 'dam:Asset'}}

From the above observation, it is noted that I am encountering this exception:

Caused by: com.github.jknack.handlebars.HandlebarsException: inline@107adee3:5:21: found: '=', expected: '}}'
    {{#if '{{nodeType}}' == 'dam:Asset'}}

I tried with {{#if '{{nodeType}}' = 'dam:Asset'}}, still the same issue. 
Please let me know the appropriate syntax.

_ Thanks

Hi, 

The problem is your Handlebars syntax is incorrect. In Handlebars, you don't need to use {{ and }} inside an {{#if}} block, as you're already in the Handlebars context. I think below will be the correct syntax 

{{#if (eq type 'dam:Asset')}}

But please check the documentation to fix it: https://handlebarsjs.com/guide/builtin-helpers.html 

Adding an additional resource where handle this scenario: https://stackoverflow.com/questions/34252817/handlebarsjs-check-if-a-string-is-equal-to-a-value 

Hope this helps
