Permissions with CD's Copied from Win
I've recently installed a new server here. This is my first Samba
install so I'm a newbie. We are using RH9 and Samba 2.2.7a. Everything
with the transition from the old server to the new went great. I do seem
to have one little bug though that I've been unable to work out. If one
of the users copies the contents of a CD to the server the permissions
for the folder and files copied are

How to DRY up validates_presence_of
Given the case of validating the presence of an attribute and then
performing other tests on said attribute, how do you go about not having
to check for nil in the other tests?
Example:
validates_presence_of :start_date, :end_date
validate :validate_start_date_before_end_date
def validate_start_date_before_end_date
# without this check an exception will be thrown on access to the

Suggestion: `before_save on: :create` should either work or raise an exception
There''s a small inconsistency in ActiveRecord''s callback syntax that has
tripped me up before. It wouldn''t be a big deal, but it can lead to a
silent failure. I''d like to suggest that it either be made consistent or be
made to fail loudly.
The issue is that to do something before validating, but only when
creating, you use `before_validation on: :create`,

model filter?
Hi All,
Is there a way to filter / modify the output of a model class before
it''s returned to controller/view that''s calling it?
Example: I have a field phone_number which I always want to preformat
using the number_to_phone() helper....
Any help is appriciated.
Thanks!

before before_validation callback
Hi,
I was looking around a bit and couldn''t find any callbacks that
executed before before_validation
The current problem with using before_validation is that it won''t fire
if I''m not using validations with #save(:validate => false) - which
makes sense. Before_save won''t suffice because I want these callbacks
to fire before validation on the occasions that

Working around/with Restful Authentication
I''m using Restful Authentication, and the code to create a user is

But for some reason when I try to create a user programmatically in
the controller like this:

Rails debugging - a (slightly) better approach?
Hi all,
First up hello everybody, I''m new to this forum.
I am also new to Ruby and Rails. One thing that struck me as very
inconvenient for someone just learning the Rails ropes is that (apart
from Arachno and Komodo, which at the moment I cannot afford - and don''t
particularly like) there is no reasonable debugging support for Rails.
I know about breakpointer which - while

I need to allow login based on the phone number. During the signup they
can give the number in any format with spaces, slash or (). But for
storing in database and then during login to compare I just want the 10

storing to db ?

validates_presence_of validation order?
I have a form with 3 fields: user_id, email and password.
All 3 fields are required, so I have a "validates_presence_of :user_id,
:email, :password" in my model.
Works, but the validation errors show up in a different order than I
specificed in the validates_presence_of statement.
Is there a way to specify the order in which the validations (and
corresponding error messages) should

Weirdness with validates_presence_of

validates_presence_of in a mixed-in module?
Anyone got any idea of how to use built-in validation methods in a
mixed-in module.
What I''ve got at the moment is each class that needs ranking methods
includes [the module] Ranking. Then the module Ranking has a bunch of
instance methods and a submodule ClassMethods. The ClassMethods in this
are mixed in to the class with self.included. So far so good.
But I want the module to
