Rails: Devise not sending confirmation email in production (Heroku)

问题

I'm trying to set up email confirmation for new users for my site on Heroku. It works fine in development (it's sent from the correct email, even though I never specified it in development.rb)

Here is the code in development.rb: (I was using MailCatcher)

config.action_mailer.raise_delivery_errors = true
config.action_mailer.default_url_options = { :host => 'localhost:3000'}
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {:address => "localhost", :port => 1025}

Here is the code in production.rb:

config.action_mailer.default_url_options = {:host => 'myapp.herokuapp.com'}
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.smtp_settings = {
   :address => "smtp.gmail.com",
   :port => 587,
   :domain => 'myapp.herokuapp.com',  #I've also tried changing this to 'gmail.com'
   :authentication => :plain, # I've also tried changing this to :login
   :enable_starttls_auto => true,
   :user_name => 'mygmailaccount@gmail.com',
   :password => 'mypassword'
 }

And here are the last few (of a very long list of) Heroku logs when I type "heroku logs" in the command prompt:

2013-11-24T18:51:01.069086+00:00 app[web.1]:   Rendered layouts/_header.html.erb

The production site on Heroku just says "We're sorry, but something went wrong." The email never gets sent. The account with the specified email is never logged into the database.

Edit: Here are the log files after I added config.log_level = :debug

2013-11-24T20:35:31.602702+00:00 heroku[router]: at=info method=GET path=/favico

And another one:

webrick/httpserver.rb:138:in `service'

These are only the last few logs. The entire log is too long to copy on here. I'm not sure what to be looking for.

回答1:

I have a similar setup for a Rails app in Heroku that uses Gmail. Here's the differences...

The domain key in you ActionMailer smtp_settings shouldn't be necessary as that is only used for Google Apps for Business. Try removing that config variable and re-deploying your app.

Also, my config doesn't have the following:

config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true

I'd recommend removing those lines as well.

Finally, my default_url_options line has a key of protocol with a value of http. So, changing that config may help as well:

config.action_mailer.default_url_options = {:host => 'myapp.herokuapp.com', :protocol => 'http'}

Production.rb

  config.action_mailer.delivery_method = :smtp

  config.action_mailer.perform_deliveries = true

  config.action_mailer.raise_delivery_errors = true

  config.action_mailer.default_url_options = { :host => 'myapp.herokuapp.com', :protocol => 'http' }

  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'gmail.com',
    user_name:            'example@gmail.com',
    password:             'Your gmail password',
    authentication:       'plain'
  }
