ActionController::RoutingError (uninitialized constant ResourceController::Singleton)

[jensb]

Hello,

for some reason my singleton resources display strange behaviour after upgrading to Rails 3:

• when I first start my application, or restart it, they work normally.
• subsequent reloads (in devel mode) display the above error message.

The same thing happens when using Apache with Passenger and instead of (re)starting, doing "touch tmp/restart.txt".

All normal resources, and all resources inheriting from ApplicationController and then using the "resource_controller" keyword, still work as expected.

I use Rails 3.0.5, Apache 2.2 with Passenger 3.0.3.

Is this a known bug?
If not, how can I track it down?

Thank you!

Regards
Jens

Hi Jens,

This issue was not known, but I can reproduce it.

It seems, the combination of the "unloadable" in resource_controller/singleton.rb plus the "autoload" in resource_controller.rb do not play nice together any more. I think the "unloadable" is (or was) required to keep the ApplicationController be reloadable in development.

I'm not sure at this point how this can be fixed to keep the ApplicationController reloadable as well as maintain Rails 2 compatibility. If you find out, let us know.

As a workaround you can put

require_or_load 'resource_controller/singleton'

at the top of your singleton controllers.
