read params

If what you want is to verify that the email is unique/valid, put these two lines in your model.

  validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "Invalid email"   validates_presence_of :email

If you really want to modify whatever the user passed in, you can do something like this:   params[:user][:email] = "some@otheremail.com"

What does your controller look like?

xinu,

def new # ... end

Goes in your controller!

this is my controller.

class UserController < ApplicationController

  def index   end

  def new     @user = User.new(params[:user])     return unless request.post?       if @user.save       redirect_to(:action => 'index')     end   end

  def edit   end

  def list   end

end

it works, but when I add the line @user.name = params[:user][:email] I receive the error message.

puts params[:user].inspect {"name"=>"abc", "email"=>"abc@def.com"}

I thing the problem is I, cannt read "email"=>"abc@def.com" with params[:user][:email]

You've got to make sure you only access params[:user][:email] on a post, because params[:user] will be nil on a get, and you'll get an error.

I think you are trying to access both the user and the email and store in the user table right? if that is the case you can do something like this User.new("user" => params[:user], email => params[:email]).
