Sending email with Rails 3 error

I am learning to how send email with Rails 3 with Agile Web Development Book, Task H. However, I keep getting the following error:

ArgumentError in OrdersController#create

wrong number of arguments (1 for 0)
Rails.root: /Applications/XAMPP/xamppfiles/htdocs/rails_projects/TUTORIALS/depot

Application Trace | Framework Trace | Full Trace
app/mailers/notifier.rb:4:in `order_received'
app/controllers/orders_controller.rb:57:in `block in create'
app/controllers/orders_controller.rb:52:in `create'

I have looked at similar discussions on gmail configuration, using setup_mail.rb here and there, but wasn't able to remove the error.

My config/environment.rb file (because i want same for dev/test/production)has my gmail details with xxxx and yyyyy:

 Depot::Application.configure do
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :address => "smtp.gmail.com",
    :port => 587,
    :domain => "gmail.com",
    :authentication => "plain",
    :user_name => "xxxxxx@gmail.com",
    :password => "yyyyyyy",
    :enable_starttls_auto => true
}
end

model/notifier/order_received.text.erb has this:

Dear <%= @order.name %>
Thank you for your recent order from The Pragmatic Store.
You ordered the following items:
<%= render @order.line_items %>
We'll send you a separate e-mail when your order ships.

and finally, models/controller/orders_controller has def create method with the line Notifier:

def create 
   @order = Order.new(param开发者_Go百科s[:order]) 
   @order.add_line_items_from_cart(current_cart) 
   respond_to do |format| 
      if @order.save Cart.destroy(session[:cart_id]) 
          session[:cart_id] = nil 
          Notifier.order_received(@order).deliver 
          format.html { redirect_to(store_url, :notice => 'Thank you for your order.') }
      else 
          format.html { render :action => "new" } 
          format.xml { render :xml => @order.errors, :status => :unprocessable_entity }
      end 
   end 
end

I feel my email configuration was probably not done correctly, but not sure which one. Thanks!

EDIT: I managed to solve it! Instead of smtp i used sendmail. As for the number of arguments error, the app/mailers/notifer.rb looks like this:

class Notifier < ActionMailer::Base
  default :from => 'Sam Ruby <depot@example.com>'

  def order_received(order)
    @order = order
    mail :to => order.email, :subject => 'Pragmatic Store Order Confirmation'
  end

  def order_shipped(order)
    @order = order
    mail :to => order.email, :subject => 'Pragmatic Store Order Shipped'
  end
end

Although my emails and everything still works, i'm curious whether anyones know why the smtp doesn't work, and sendmail does.

You've got a space in your order_received definition:

def order_received (order)

That should be this:

def order_received(order)

Is it this line in create?

if @order.save Cart.destroy(session[:cart_id])

If that's what you really have then Ruby will try to pass whatever Cart.destroy returns to @order.save as an argument, the above is equivalent to this:

if(@order.save(Cart.destroy(session[:cart_id])))

However, the save method doesn't take any arguments so you get a "wrong number of arguments (1 for 0) in OrdersController#create" error message. I'd guess that you mean:

if @order.save
  Cart.destroy(session[:cart_id])
  # etc.
