Hi there,
is there a way in Rails to use helpers in an Initializer ?
You should never need to. Helpers are only for generating view code,
and you shouldn't be doing that in initializers.
If yes, how ?

Basically, I put some Rufus scheduler code in the Initializer folder so

To my casual eye this seems like something that should go
If you really want to use an existing Rails helper in your
controllers, do the following :
1. add the following the following code to your
application_controller (a singleton and a method):
class Helper
include Singleton
include ActionView::Helpers::DateHelper
include
Helper methods are used in the template class (ActionView::Template),
not controllers. If I'm reading the documentation right, putting
helper :all in a controller makes all helpers found in app/helpers/

I guess I did not made myself clear.
I said create a module somewhere (usually under the lib folder), like:

module Points
def create_points_account( pts )
f = PointAccount.new(:points = pts)
f.resource = self
return false if !f.save

end

Yes. In your module you've defined an instance method not a class
method.
But this:
class CarePhase ActiveRecord::Base
include ModelHelper
pretend_helper(hi!)
Is the class trying to call the method, which fails because the class
doesn't know about the 'pretend_helper' method.
Another option is to inject an abstract class model between AR and the
rest of your models.
some class GenericModel ActiveRecord
where GenericModel implements all manner of standard infrastructure
functionality that is written once. Very easy for a specific model to

I ended up writing a module and sticking it in the lib directory. In
order to make these methods available to your models, simply include it

Helper means view helper: they are only included in views. If you want
a method you can call from views or controllers you need to define it
in your controller (if you need all controllers to see it then in
ApplicationController) and use helper_method to make it accessible to
views.
Fred
Okay, so how would you allow a controller (or even a model) to use for
instance the helpers truncate or sanitize?
The solution I have found was to use xss_terminate plugin (compatible
with Rails 2.2.2), it also allows to dive into its code and see how it
is coded.

You'll want to put the shared method in app/controllers/application.rb
Unless find_cart is used only in the one controller, then you just need
to turn it into a before_filter:
class MainController ApplicationController
before_filter :set_cart
