ActionMailer 在生产中不起作用

Question

我的应用程序的所有功能都可以使用，除了电子邮件功能。一切正常，并且在开发中符合预期。我使用 DigitalOcean 的 Ruby on Rails 一键式服务器设置来托管该应用程序。这是说明的链接：https://www.digitalocean.com/community/tutorials/how-to-use-the-ruby-on-rails-one-click-application-on-digitalocean

这是我的开发.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in    config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  #DEVISE WANTS THIS
  config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations.
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = true

  # Asset digests allow you to set far-future HTTP expiration dates on all assets,
  # yet still be able to expire them through the digest params.
  config.assets.digest = true

  # Adds additional error checking when serving assets at runtime.
  # Checks for improperly declared sprockets dependencies.
  # Raises helpful error messages.
  config.assets.raise_runtime_errors = true

  # Raises error for missing translations
  # config.action_view.raise_on_missing_translations = true

  #Action Mailer
  config.action_mailer.perform_deliveries = true

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      address:              'p3plcpnl0334.prod.phx3.secureserver.net',
      port:                 465,
      domain:               'finaltouchsecurity.com',
      user_name:            'receipts@finaltouchsecurity.com',
      password:             'xxxxxxxxxx',
      authentication:       'plain',
      #enable_starttls_auto: true 
      ssl: true }

end

这是我的制作.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in  config/application.rb.

  # Code is not reloaded between requests.
  config.cache_classes = true

  # Eager load code on boot. This eager loads most of Rails and
  # your application in memory, allowing both threaded web servers
  # and those relying on copy on write to perform better.
  # Rake tasks automatically ignore this option for performance.
  config.eager_load = true

  # Full error reports are disabled and caching is turned on.
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Enable Rack::Cache to put a simple HTTP cache in front of your application
  # Add `rack-cache` to your Gemfile before enabling this.
  # For large-scale production use, consider using a caching reverse proxy like
  # NGINX, varnish or squid.
  # config.action_dispatch.rack_cache = true

  # Disable serving static files from the `/public` folder by default since
  # Apache or NGINX already handles this.
  config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = false

  # Asset digests allow you to set far-future HTTP expiration dates on all assets,
  # yet still be able to expire them through the digest params.
  config.assets.digest = true

  # `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb

  # Specifies the header that your server uses for sending files.
  # config.action_dispatch.x_sendfile_header = 'X-Sendfile' # for Apache
  # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for NGINX

  # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
  # config.force_ssl = true

  # Use the lowest log level to ensure availability of diagnostic information
  # when problems arise.
  config.log_level = :debug

  # Prepend all log lines with the following tags.
  # config.log_tags = [ :subdomain, :uuid ]

  # Use a different logger for distributed setups.
  # config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

  # Use a different cache store in production.
  # config.cache_store = :mem_cache_store

  # Enable serving of images, stylesheets, and JavaScripts from an asset server.
  # config.action_controller.asset_host = 'http://assets.example.com'

  # Ignore bad email addresses and do not raise email delivery errors.
  # Set this to true and configure the email server for immediate delivery to raise delivery errors.
  # config.action_mailer.raise_delivery_errors = false

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation cannot be found).
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners.
  config.active_support.deprecation = :notify

  # Use default logging formatter so that PID and timestamp are not suppressed.
  config.log_formatter = ::Logger::Formatter.new

  # Do not dump schema after migrations.
  config.active_record.dump_schema_after_migration = false
end

我的控制器

def create
    @job = Job.find(session[:edit_job])
    @receipt = @job.receipts.create(params.require(:receipt).permit(:email, :information))  
    if @receipt.valid?
        begin
            email
            render :js => "window.location = '/jobs/#{session[:edit_job]}/edit'"
        rescue
            @receipt.destroy
            flash[:error] = "Error Sending Email!"
            render "layouts/fail"
        end
    else
        flash[:error] = "Error Creating Receipt!"
        render "layouts/fail"
    end
end

def email
            CustomerMailer.email_receipt(@receipt).deliver_now
            flash[:notice] = "Email Sent Successfully."     
end

我不确定如何检查我的服务器日志，但我很肯定电子邮件功能正在引发错误，因为闪存在我的错误消息中表明了这一点。

config.action_mailer.smtp_settings 设置在 development 中，但不在 production 中，因此 Rails 尝试连接到默认值，即 localhost:25。您需要将该配置添加到config/environments/production.rb。

如果您在两个环境中的设置相同，您可以将您拥有的配置（smtp_settings 和 delivery_method）从 config/environments/development.rb 移动到 config/application.rb - 后者是在所有环境中运行的全局配置。如果你这样做，你需要在config/environments/test.rb 中将delivery_method 设置回:test，这样你就不会在测试期间意外发送邮件。
