ApplicationController.helpers_path is empty?

[ghost]

Hey,

After upgrading to .rc8, ApplicationController.helpers_path returns an empty array.
This application is one I'm upgrading from Rails2(the upgrade isn't anywhere near ready yet).

Helpers other than those in ApplicationHelper aren't available in ApplicationController._helpers.instance_methods.
If i call reload!, they become available.

config.action_controller.include_all_helpers = true makes no difference here. neither does helper :all.
manually calling helper :foo works, however.

This application worked in respect to helpers on .rc6

Has the boot process changed in anyway?
I can't reproduce this bug on a fresh rails .rc8 project, so anything I can do to debug further would be appreciated.

(Btw, I've tried setting .helpers_path myself, it made no difference).
I'm at a loss as to what might be happening, as it isn't reproducible on a fresh Rails3 .rc8 project.

I realize I'm not providing a reproducible bug, and I'm sorry for that, but I can only reproduce it on my works app, which i can't share unfortunately.

Thanks.

@robgleeson Is this still an issue?

@robgleeson @isaacsanders @steveklabnik It's not an issue in master, but it will be nice if you can provide more information.

irb(main):007:0> ApplicationController.helpers_path

👍 on more information.

I have no idea. :/ Since it's not an issue, I'm going to close, but since this isn't reproducible on a fresh app, I don't even know how to go about figuring out what went wrong.

I know this is like beyond necrobump, but hey, I had the same problem and tracked down the cause (at least in my case), so figured I'd share.

This can happen if Rails::Application#helpers_paths is called too early, before the configuration object has fully loaded or whatever. In my case, this was because a very old gem was creating an initializer that autoloaded ApplicationController, setting off all the loading much earlier than it otherwise happens. Changing that to a config.to_prepare block solved the problem.

@iangreenleaf fucking thank you. I owe you a beer.

Holy crud. I just spent about a day debugging this issue. Finally came across this thread which tipped me off, so thank you! In my case the offending gem is grape-rails-routes.
