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

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 think that's exactly what I was looking for, thank you very much...

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