config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
# change to true to allow email to be sent during development
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true

config.action_mailer.smtp_settings = {
  address: "smtp.gmail.com",
