Rails 3 development environment keeps caching, even without caching on?

Question

i have a rails 3 app in dev mode that won't load any changes i make when its running webrick. i triple checked the settings for my development.rb and made sure i am running in development mode.

config.cache_classes = false
config.action_controller.perform_caching = false

i also checked my tmp directory to make sure the cache folder is empty - i have yet to do any caching on the site and have never turned on caching. im guessing its a loading problem with the files.

also i was running on webrick then installed mongrel and the problem still persists.

im guessing ive run into a config problem, bc i dont see anyone else posting such a prob. anything else im missing?

EDIT: it looks like my view helpers aren't auto loadable - aren't helpers by default supposed to be reloadable in rails 3?

Answer 1

I've had a similar experience, but I don't believe it was with an actual helper class, it was with anything I wrote under the lib/ directory. If you've had to use a require 'some_class' statement, then you should switch it to:

require_dependency 'some_class'

Worked like a charm for me.

Answer 2

I had the same problem and here is the simple solution.
In your config/environments/development.rb set following settings:

config.action_controller.perform_caching = false
config.perform_caching = false
config.cache_store = :null_store
