Is there a way to check if an inline partial is defined?

[peter-affenzeller]

in the inline partials example, the inline partials of nav and content are each wrapped inside a div.
if one of those partials is not defined, the wrapping div will still be created, which in my case leads to issues since I am using a grid container, which is creating a new row for the div and hence also gaps before/after the new row, even though there is nothing in it.

is there some way to check if the inline partial actually exists?
something like:

{{#if (hasInlinePartial "nav"}}
<div class="nav">{{> nav}}</div>
{{/if}}

I couldn't find anything in the options passed to helper functions...

Checking if you found a solution to this?

[peaffenzeller]

unfortunately not, no, but wasn't too bad in my case, we ended up always having all the inline partials, else I would have had some useless wrapping divs introducing equally useless spacings, but could have probably worked my way around that with a couple more css rules...
what would work (even though not an ideal solution...) is to just add more props to the partial ("parent" partial, not the inline partials), like hasContent or hasCTA, depending on the inline partials, and check for those.

Just implemented the hasInlinePartial hack suggested above which worked for me. Pity there's not a more elegant way to do this.

Could you share your hack?

[rpaterson]

In addition to the inline partial I pass in a boolean flag. Like this:

{{#> myPartial hasMyInlinePartial=true}}
    <other-html-1>
    {{#* inline "myInlinePartial" }}
        <some-html>
    {{/ inline}}
    <other-html-2>
{{/myPartial}}

or

{{#> myPartial}}
    <other-html-1>
    <other-html-2>
{{/myPartial}}

Then in myPartial.hbs:

{{#if hasMyInlinePartial}}
    <div>{{> myInlinePartial}}</div>
{{/if}}

Well, I came to the same decision. Thanks.

Not used handlebars out of the box myself - used via foundation zurb panini

I was testing the"Inline partial" and used with"Partial Blocks Fallover" to cater for this but was looking for an alternative inbuilt solution.
Was wondering if there was a way to detect if a partial exists - apparently not.

Any how the "Partial Blocks Fallover" can be an alternative technique which could be used.
Make the fallover content empty.

The inline partial would need to cater for any wrapper markup.

Something like this - https://handlebarsjs.com/examples/partials/inline-blocks.html modified

{{#> layout}}
  {{#*inline "nav"}}<div class="nav">My Nav</div>{{/inline}}
  {{#*inline "content"}}My Content{{/inline}}
{{/layout}}

{{#> nav}}No nav specified{{/nav}}
<div class="content">{{> content}}</div>
