UserMailer with Devise - ruby-on-rails-3

Question

am using my custom mailer UserMailer to send emails. It works perfect in development, but in production i get error 500, that is when am trying to retrieve my password on forgetting.
here is what is in the production logs in the production mode
Processing by Devise::PasswordsController#create as HTML
Parameters: {"utf8"=>"✓","authenticity_token"=>"xxxxxxxxxxxxxxx", "user"=>{"email"=>"sam#gmail.com"}, "commit"=>"Send me r$
Completed 500 Internal Server Error in 2ms

my mailer configuration. user_mailer.rb
class UserMailer < Devise::Mailer
default :from => "info#xxxxxxxx.com"
def signup_confirmation(user)
#user = user
mail :to => user.email, :subject=> "Thank you for signing with us"
end
# send password reset instructions
def reset_password_instructions(user)
#resource = user
mail(:to => #resource.email, :subject => "Reset password instructions", :tag => 'password-reset', :content_type => "text/html") do |format|
format.html { render "devise/mailer/reset_password_instructions" }
end
end
end
production.rb file
config.action_mailer.default_url_options = { :host => 'https://xxxxxxxxxx.com' }
config.action_mailer.raise_delivery_errors = false
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'info#xxxxxxxx.com',
:user_name => 'yyyyyy',
:password => 'zzzzzzzz',
:authentication => 'plain',
:openssl_verify_mode => 'none',
:enable_starttls_auto => true
}
your assistance will be highly appreciated

Answer 1

Okay from the looks of it your mailer looks wrong. Especially the set up. By default you can create a mailer like this:
class UserMailer < ActionMailer::Base
default :from => DEFAULT_FROM
def registration_confirmation(user)
#user = user
#url = "http://localhost:3000/login"
mail(:to => user.email, :subject => "Registered")
end
end
What I did notice in your example is that your doing:
class UserMailer < Devise::Mailer
Your inheriting from Devise's Mailer when in actual fact you shouldn't have do any of this! You may also want to check your config/initalizers/devise.rb and set theconfig.mailer_sender=example#gmail.com` if you haven't. So what I suggest you doing is make your mailer look like the following:
class UserMailer < ActionMailer::Base
default :from => "info#xxxxxxxx.com"
def signup_confirmation(user)
#user = user
mail :to => user.email, :subject=> "Thank you for signing with us"
end
Also another thing... I noticed that your default url is: config.action_mailer.default_url_options = { :host => 'https://xxxxxxxxxx.com' } there is no need for https so it should really look like config.action_mailer.default_url_options = { :host => 'xxxxxxxxxx.com' }. Because when you try to fire anything what will happen is that it will be doing https://https://https://xxxxxxxxxx.com. This is an easy mistake for people to make.
And I also believe the cause of this may be due to the fact you have not set the class that is responsible for sending your e-mails.
Other possible solution that may fix your problem
Notice that in config/intializers/devise.rb that there is the following line which is commented out:
# Configure the class responsible to send e-mails.
# config.mailer = "Devise::Mailer"
Uncomment this and set this to your class you are using which in your example so that it would be
config.mailer = "UserMailer" # UserMailer is your mailer class
Also in app/mailers/user_mailer.rb you should have:
class UserMailer < ActionMailer::Base
include Devise::Mailers::Helpers
default from: "default#mydomain.com"
def confirmation_instructions(record)
devise_mail(record, :confirmation_instructions)
end
def reset_password_instructions(record)
devise_mail(record, :reset_password_instructions)
end
def unlock_instructions(record)
devise_mail(record, :unlock_instructions)
end
# you can then put any of your own methods here
end
May also want to generate your own views:
rails generate devise:views
also move the email templates from app/views/devise/mailer/ to app/views/user_mailer/
mv app/views/devise/mailer/* app/views/user_mailer/

Do everthing #david has said. except change this for the Devise > 3.2.4
class UserMailer < ActionMailer::Base
include Devise::Mailers::Helpers
def confirmation_instructions(record, token, opts={})
#token = token
devise_mail(record, :confirmation_instructions, opts)
end
def reset_password_instructions(record, token, opts={})
#token = token
devise_mail(record, :reset_password_instructions, opts)
end
def unlock_instructions(record, token, opts={})
#token = token
devise_mail(record, :unlock_instructions, opts)
end
