How can I selectively turn of validations

rubyonrails-talk

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.

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

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

What I'm doing looks like this:

validates_format_of :password, :with => /^\w+$/, :message => '<b style = "color:red">Password must be alphanumeric</b>', :on => :save

validates_length_of :password, :minimum => 5, :message => '<b style = "color:red">Password to short (Must be 5 characters long)</b>', :on => :create

5

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 => '<b style ="color:red">Password must be alphanumeric</

',

     :on => :save      :if => @skip_password_validations

The parameter can even be a Proc!
