Hi,

does your model inherit from ActiveRecord::Base? If it doesn’t then  
it won’t get reloaded automatically and you’ll have to do a little  
extra work:

In rails 1.0 you can put this into your app/controllers/  
application.rb file:

require\_dependency ‘toto’

And in rails 1.1 you can use the Reloadable mixin. So in app/models/  
toto.rb you have:

class Toto  
include Reloadable

# the rest of your stuff here

end

## HTH, Trevor
