Hi,

I got a plugin that extends ActionController::AbstractRequest. After  
updating Rails from 2.2.2 to 2.3.0 I’m getting the following error:

‘load\_missing\_constant’: uninitialized constant  
ActionController::AbstractRequest (NameError)

I’ve already seen people having similar problems with i.e. TMail and  
Sweeper. I guess that some kind of lazy loading mechanism has been  
introduced, but how to fix this problem?

Cheers,  
Szymek

There’s also the fact that ActionController::AbstractRequest no  
longer exists.

I’m also having the same issue.

What are the options for refactoring existing code? What has replaced  
AbstractRequest? or is it now a Gem?

I seem to recall it’s just ActionController::Request now (which  
inherits from Rack::Request). Exactly what you need to change probably  
depends on what you were doing.

I am also having issues with this in trying to use webrat, is there a  
way of aliasing the old name or something like that to have backwards  
compatibility ?

Thanks,
