Rails - May 2007 - Validation question

Hello all,

I have a controller with a couple of actions and one model.
The model is as so:

validates_presence_of :name, :email, :name
validates_presence_of :password, :password_confirmation

The first action is create and is called by the administrator.
With this action I do not want to validate the password as this is created
automatically.

The second action allows the user change their password.
With this action I do not want to validate the email, as there is no need.

However the problem lies in the fact that the Administrator can also change
the name and email.
Therefore I am unable to use the :on => create or :on => update, as
password
validation is required on update for the user,
while email and name validation is required on update and create by the
administrator.  Quite the pickle!  Is there a way of
restricting validation to a controller/action?  Therefore I can avoid
calling certain validations at certain actions?

Thanks,

j

a simple suggestion on the top of my head would be to create two 
different actions for the admin / user. instead of :update, make two 
identical actions, with different names such as :update_for_user && 
:update_for_admin and then just set the

validates_* to :update_for_user
and
validates_* :update_for_admin

in the correct cases.

This is how I did it. Sounds similar to what you need.

Model:

class Customer < ActiveRecord::Base
    attr_accessor :current_password
    validates_presence_of :current_password, :on => :update, :if =>
:password_change?

    def change_password(attributes)
      @password_change = true
      self.attributes = attributes
      save
    end

    private

        def validate_on_update
            if password_change?
                errors.add(:current_password, "is incorrect") unless
encrypt(current_password) == crypted_password
            end
        end

        def password_change?
            @password_change
        end
end

Controller:

class AccountController < ApplicationController
    def change_password
        @customer = @current_customer
        if request.post?
            if @customer.change_password(params[:customer])
                flash[:notice] = "Your password has been changed"
            end
        end
    end
end

I tried that, it doesn''t work as there are no such parameters for a
validation helper.
