Rails Mailers Not Working with C9 IDE?

rails

#1

Cannot GET /c9User/projectname/rails/mailers/user_mailer/account_activation

I am following through with the Rails Tutorial by Michael Hartl but have come to a bump in the road when trying to preview my mailers using the Cloud 9 IDE.

Here is my user_mailer.rb

class UserMailer < ApplicationMailer

def account_activation(user)
@user=user
mail to: user.email, subject: "Activate your focus. account"
end

def password_reset
@greeting = “Hi”

mail to: "to@example.org"
end
end
My problem is when I attempt to preview my mailers using the link

http://ide.c9.io/-workspacename-/rails/mailers/user_mailer/account_activation

I get a blank page with the following error:

Cannot GET /dev_focus/focus/rails/mailers/user_mailer/account_activation

Any Ideas?

Thanks for your help!
