500发送电子邮件通知时发生内部服务器错误

Question

我在使用邮箱gem的Heroku上尝试设置邮件的电子邮件通知。

邮件已创建，但尝试通过电子邮件通知联系收件人时超时。

消息控制器：

def create 
    @recipient = User.find(params[:user]) 
    current_user.send_message(@recipient, params[:body], params[:subject]) 
    flash[:notice] = "Message has been sent!" 
    if request.xhr? 
     render :json => {:notice => flash[:notice]} 
    else 
     redirect_to :conversations 
    end 
    end 

Mailboxer.rb：

Mailboxer.setup do |config| 

    #Configures if you applications uses or no the email sending for Notifications and Messages 
    config.uses_emails = true 

    #Configures the default from for the email sent for Messages and Notifications of Mailboxer 
    config.default_from = "[email protected]" 

    #Configures the methods needed by mailboxer 
    config.email_method = :mailboxer_email 
    config.name_method = :name 

    #Configures if you use or not a search engine and wich one are you using 
    #Supported enignes: [:solr,:sphinx] 
    config.search_enabled = false 
    config.search_engine = :sphinx 
end 

用户模型：

def mailboxer_email(object) 
    if self.no_email 
     email 
    else 
     nil 
    end 
end 

Production.rb：

config.action_mailer.delivery_method = :smtp 
    config.action_mailer.default_url_options = { :host => 'domain.herokuapp.com' } 
    config.action_mailer.smtp_settings = { 
    address:    'smtp.gmail.com', 
    port:     587, 
    domain:    'gmail.com', 
    user_name:   '[email protected]', 
    password:    'password', 
    authentication:  'plain', 
    enable_starttls_auto: false } 

    config.action_mailer.default_url_options = { :host => "domain.herokuapp.com" } 

    config.action_mailer.perform_deliveries = true

Answer 1

这指出您的电子邮件生成大约需要60秒，如果我没有弄错Heroku在30秒后超时。

Answer 2

它说的你有messages_controller.rb行号错误15

应用程序/控制器/ messages_controller.rb：15

Answer 3

要使用Gmail，您需要确保它能够绕过Google的现代安全协议。

虽然我可以解释如何做，但我建议使用Mandrill，Sendgrid，Mailjet或其他电子邮件程序，因为Gmail只允许您每天最多可收到500个收件人的电子邮件。

个人而言，我使用Mandrill，并且喜欢在RoR之外设置电子邮件模板，运行A-B测试以及跟踪谁打开/查看电子邮件。
