NameError: uninitialized constant GovukComponentsHelper

[aliuk2012]

I've been trying to add govuk-components to another rails service and came across this issue while trying to deploy the app to production. Everything seems to work and run correctly in development. I'm not sure if perhaps its a config setting in the rails app that is making the server fail when it starts up.

Interesting. I can recreate locally by changing config.load_defaults from 5.2 and 6.0 as you say in the referenced ticket.

It would appear that between the two versions of Rails, something has changed in the way helpers are loaded. There's more info here, I'll have a closer look over the next day or two.

Scratch the above, the helper module is called GovukComponentHelper (singular) and the file is govuk_components_helper.rb (plural), that's probably the cause. I'll fix it tomorrow.

I was wondering if it was because of the filename here https://github.com/DFE-Digital/govuk-components/blob/master/app/helpers/govuk_component**s**_helper.rb but inside the file the module is GovukComponentHelper
