How can I selectively turn of validations

Rails
1

Hi,

   I need to selectively turn off validations for example, I want to

make sure that password and password_confirmation fields are equal when
user
first signs up or changes his password from his profile, but not in
other
cases e.g. updates his profile.

   right now I am using a quick and dirty hack by using booleans

e.g.
if(@skip_password_validations != false) #–do validations --#

  is there anything better than this. any help would be greatly

appreciated.

def skip_password_validations?
@skip_password_validations
end

or even
with_options :unless => skip_password_validations? do
validates_presence_of :password
validates_presence_of :password_confirmation
validates_confirmation_of :password
end

Something like this:

validates_presence_of :password, :unless =>
:skip_password_validations?
validates_presence_of :password_confirmation, unless =>
:skip_password_validations?
validates_confirmation_of :password, unless =>
:skip_password_validations?

def skip_password_validations?
@skip_password_validations
end

Thanks a lot, that really helps cleaning the code a little

What about the :if parameter that validations can take?

Like this:

validates_format_of :password,
:with => /^\w+$/,
:message => ‘Password must be alphanumeric</
b>’,
:on => :save
:if => @skip_password_validations

The parameter can even be a Proc!

What I’m doing looks like this:

validates_format_of :password, :with => /^\w+$/, :message => ‘Password must be alphanumeric’, :on => :save

validates_length_of :password, :minimum => 5, :message => ‘Password to short (Must be 5 characters long)’, :on =>
:create
