500發送電子郵件通知時發生內部服務器錯誤

Question

我在使用郵箱gem的Heroku上嘗試設置郵件的電子郵件通知。

郵件已創建，但嘗試通過電子郵件通知聯繫收件人時超時。

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 = "no-reply@domain.com" 

    #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 

用戶模型：

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:   'username@gmail.com', 
    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

這指出您的電子郵件生成大約需要60秒，如果我沒有弄錯Heroku在30秒後超時。

Aug 14 12:12:23 domain app/web.1: Sent mail to email@hotmail.com (60151.4ms) 
Aug 14 12:12:23 domain app/web.1: Sent mail to email@hotmail.com (60151.4ms) 

Answer 2

它說的你有messages_controller.rb行號錯誤15

應用程序/控制器/ messages_controller.rb：15

Answer 3

要使用Gmail，您需要確保它能夠繞過Google的現代安全協議。

雖然我可以解釋如何做，但我建議使用Mandrill，Sendgrid，Mailjet或其他電子郵件程序，因爲Gmail只允許您每天最多可收到500個收件人的電子郵件。

個人而言，我使用Mandrill，並且喜歡在RoR之外設置電子郵件模板，運行A-B測試以及跟蹤誰打開/查看電子郵件。
