So any other ideas as to why my custom class under app/models is being cached even though all the caching is set to false in the config/environments/\* files? Currently I’m having to restart WEBrick after EVERY change to the file. The controllers and views are reloading just fine and not being cached. It’s just the custom class I created that’s being cached. Any ideas as to what I should try to get it to stop caching the class? Thanks, - Brent ---

I don’t know that it’s server-determined, but for what it’s worth you can add lighttpd to the list of servers under which it happens 🙂 David > > - Brent > > * * * > > Rails mailing list > removed\_email\_address@domain.invalid > [http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails) – David A.

I’ve grepped for all occurences of the word “cach” to see if there’s any other file which caching parameters and I’ve found nothing other than whats in the environments directory. Thanks for letting me know I’m not the only one! - Brent ---

Brent, I may be missing old history on this thread so sorry if I’m asking a question that you’ve already covered: you say “custom class”. Does your class inherit from ActiveRecord::Base? If not, and if you’re using Rails1.0 you won’t easily get class reloading. In edge-rails (and the upcoming Rails 1.1) there is a module-mixin called “Reloadable” that will allow you to mark arbitrary classes as reloadable so long as they conform to some file naming conventions. ## HTH, Trevor Trevor S.

Aha! You’re correct, the class does not inherit from ActiveRecord::Base. I am indeed using Rails 1.0, so I bet that’s the problem. Thanks for filling me in! - Brent ---

I got around this by using ‘require\_dependency’ rather than ‘require’ when requiring the file with the custom classes. Seems to work fine for most situations. Apparently this will be replaced in 1.1 with a mixin. > > HTH, > > > > > being > > > > > > > Thanks, > > > > [http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails) > > * * * > > Rails mailing list > removed\_email\_address@domain.invalid > [http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails) * * * Bob H. – blogs at \<[http://www.recursive.ca/](http://www.recursive.ca/) hutch/\> Recursive Design Inc. – [http://www.recursive.ca/](http://www.recursive.ca/) Raconteur – [http://www.raconteur.info/](http://www.raconteur.info/) xampl for Ruby – [http://rubyforge.org/projects/xampl/](http://rubyforge.org/projects/xampl/)
