Hi From what I understand about documentation about require_dependency, this function will work like require but the file will be reloaded on every request to the server when in development mode. I have bootstrapped am minimal RoR project with 0.13.1 Rails. I have created a minimal Controller and hooked up it''s "index" action at the site root. I have also created a file config/my_config.rb which only has one line: CONFIG_SETTING = ''FOOBAR'' In my controller''s view, I assign CONFIG_SETTING''s value to a variable and display this variable in the index view of my controller. I include the config/my_config.rb file with: require_dependency ''my_config.rb'' at the end of config/environment.rb. My view displays ''FOOBAR'' fine. However, when I change the value in config/my_config.rb, the view still displays ''FOOBAR'' and not the value I changed the constant to. I also tried defining a class "Foo" there with a class method "bar" and the issue is the same: The change in the file is not reflected immediately as it should from my understanding since I am in "development" mode. What am I doing wrong? Regards Manuel Holtgrewe

Also, I don''t believe you can reset constants. However, changing the class method should work. -- rick http://techno-weenie.net

It works fine when I include the configuration file with require_dependency from the file defining the controller. I''d like to have a central place to include that configuration, though, and not in every controller. Regards Manuel Holtgrewe

I would think it would work if the require was in: app/controllers/application.rb That file is shared (mixed in?) to every controller. -- -- Tom Mornini On Sep 27, 2005, at 10:29 AM, Manuel Holtgrewe wrote:> Hi. > > >> Off the top of my head, it might not be working since the >> require_dependency call is set in environment.rb?

I found an interesting snippet in the trac database in response to a
patch that was submitted for this:
http://dev.rubyonrails.com/ticket/2098
I took took from it this little bit of code, which lives in
environments/development.rb, and reloads anything inherited from the
base class
of my non-AR model(s):
require ''dispatcher''
class Dispatcher
class <<self
alias_method :original_reset_application!, :reset_application!
def reset_application!
original_reset_application!
Dependencies.remove_subclasses_for(SimpleModel) if
defined?(SimpleModel)
end
end
end
No require_dependency needed, and I am encouraged to choose a single
base class
for my non-AR models (which I only need for transient purposes, hence
the
demeaning superclass name!)
