Uninitialized constant error on fresh install

[siddhartharun]

Receiving the following error while trying to start my rails server — uninitialized constant HotwireCombobox::Helper (NameError)

Currently running Rails 7.1.1 / Ruby 3.2.2
Turbo and Hotwire are installed.

Thanks @siddhartharun! Does it show a stacktrace as well? Seeing that would be helpful

[josefarias]

Thanks!

I wonder if it's a Rails 7.1.1 thing. The docs app uses 7.1.3 with Ruby 3.2.2. You might want to give that a try if upgrading is possible.

I'll take a look at this tomorrow, though.

[josefarias]

Ah but the stacktrace shows 7.1.3 so maybe not. I'll take a closer look tomorrow.

[siddhartharun]

Yup, I just upgraded to 7.1.3 and still got the same error. No rush, and thank you for putting together this amazing gem! Can't wait to use this in my projects.

[pranavbabu]

I have same issue

[adrianthedev]

Me too!
I'm trying to add it as a field to https://github.com/avo-hq/avo

[pranavbabu]

If it helps I noticed that the first thing that required in hotwire_combobox.rb is engine.rb and inside engine.rb it has include Helper and this Helper is using methods from hotwire_combobox.rb which is not initiated yet. I tried to solve Uninitialized constant issue by requiring helper file at engine.rb and got next error that bypass_convenience_methods? method is not implemented on HotwireCombobox module.

[josefarias]

Me too!

Thanks! This is helpful since I can clone the repo and reproduce locally.

I'll try doing that in a bit. Taking a look shortly!

[adrianthedev]

I don't have a PR up yet. It might be a bit difficult to reproduce.

[josefarias]

@siddhartharun @pranavbabu @adrianthedev could I get you to try v0.1.30 (just published) and see if that solves the problem, please? I'll reopen if not.

@adrianthedev I see avo uses sprockets for JS. I haven't tested for that. I think you might need to include the js manually the same way you have to include the css. There's no helper for that yet, though. Please let me know whether or not you run into trouble in that regard so I can know if sprockets is properly supported. Maybe chime in here: #10

[adrianthedev]

Got it!
I'll let you know about the sprockets integration.
If it were up to me I'd just update to propshaft, but Avo's a gem that others use in their apps so I can't control it.

I'll try it again later this week. I'll keep you posted.

Thanks for the quick response.

[pranavbabu]

@josefarias The problem is solved, thanks for speed ;)
