[Resolved] Conditional Evaluation failing if not passed as quoted string

support
1

I encountered an issue where an if conditional is not properly evaluating a variable if it is not passed as a quoted string. Best to explain with some simple code:

The following works:
{{ range …whatever… }}
{{ $.Scratch.Add “Draft” “false” }}
{{ end }}

…some html…

{{ $draft := $.Scratch.Get “Draft” }}
{{ $draft }} (properly outputs the word ‘false’)
{{ if eq “false” $draft }}
I AM FALSE
{{ else }}
I AM TRUE
{{ end }}

As expected, the output is I AM FALSE.

However, if I change the Scratch.Add to grab a variable that is available from the page front matter, it will output it correctly but not evaluate it: (assume .md has draft = “false”)

{{ range …whatever… }}
{{ $.Scratch.Add “Draft” .Draft }}
{{ end }}

…some html…

{{ $draft := $.Scratch.Get “Draft” }}
{{ $draft }} (properly outputs the word ‘false’)
{{ if eq “false” $draft }}
I AM FALSE
{{ else }}
I AM TRUE
{{ end }}

even though {{ $draft }} returns 'false, the conditional returns “I AM TRUE”.

Q1. Why?
Q2. Is this a bug that I should be reporting?

I have found a workaround (see below for working code) but curious why if fails when obviously the value is defined.

working work-around:
{{ range …whatever… }}
{{ if eq “true” .Draft }}
{{ $.Scratch.Add “Draft” “true” }}
{{ else }}
{{ $.Scratch.Add “Draft” “false” }}
{{ end }}
{{ end }}

… html code …

{{ $draft := $.Scratch.Get “Draft” }}
{{ $draft }} (properly displays value defined in range)
{{ if eq “false” $draft }}
I AM FALSE
{{ else }}
I AM TRUE
{{ end }}

(condition properly output expected value)

Remember eq checks value equality – two different types are never equal.

So "false" != false wil always be … true.

What you really want to do (or, I’m not sure what you’re really doing) above is:

{{ if  $.Scratch.Get "Draft" }}
IS DRAFT
{{ else }}
IS NOT
{{ end }}

I did not consider data-type casting being a factor before posting. New to Hugo & Go templates. Thanks for your time and prompt reply. Greatly appreciated.
