[SOLVED] Middleman use custom helper function inside config.rb file

Middleman use custom helper function inside config.rb file

I have defined a helper function inside the config.rb file. When I use it elsewhere, it works fine. But I have to use that function inside the config.rb as well simultaniously. Unfortunately there is an error:

`method_missing': undefined method `slug' for #<Middleman::ConfigContext:0xa137b44> (NoMethodError)

Is it nevertheless possible to access a function inside the helpers in config.rb file? Or do I have to declare the function outside globally and then access it from both inside the helper function and somewhere else in the file?

Solution

I was able to get this working by requiring my helper and including the module like this in config.rb:

require 'helpers/slugify_helper'
include SlugifyHelper

Then I was able to call my helper method from config.rb like: slugify(url).

FYI: I'm running Middleman ~> 4.2.1.
