Ruby on rails Heroku 500错误

ruby-on-rails heroku

Ruby on rails Heroku 500错误,ruby-on-rails,heroku,Ruby On Rails,Heroku,在production.rb中，我有一行config.action\u mailer config.action_mailer.default_url_options = { :host => 'secret-brushlands- 1375.herokuapp.com' } 在Development.rb中，顺便说一句，我认为这似乎有效 config.action_mailer.perform_deliveries = true config.action_mailer.defau

在production.rb中，我有一行config.action\u mailer

config.action_mailer.default_url_options = { :host => 'secret-brushlands-   1375.herokuapp.com' }

在Development.rb中，顺便说一句，我认为这似乎有效

config.action_mailer.perform_deliveries = 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}

在Environment.rb中，我有：

ActionMailer::Base.smtp_settings = {
  :address        => 'smtp.sendgrid.net',
  :port           => '587',
  :authentication => :plain,
  :user_name      => ENV['sendgrid user'],
  :password       => ENV['sendgrid password'],
  :domain         => 'heroku.com',
  :enable_starttls_auto => true
}

很抱歉，出了点问题

由于某些原因，我在heroku应用程序中遇到此错误，这只是当我尝试注册时，发生在用户部分，另一个模型 postgresql上的功能似乎很酷——我做了一个heroku pg：重置 heroku运行rake:db:migrate等。。但是没有用

这是我的gem文件：

source 'https://rubygems.org'

我正在使用Desive，我已经在Heroku上安装了SendGrid。没见过电子邮件确认还没有。谢谢你的帮助

谢谢，

在config/environment.rb文件中，更改smtp\u设置的配置，如下所示：

ActionMailer::Base.smtp_settings = {
  :address        => 'smtp.sendgrid.net',
  :port           => '587',
  :authentication => :plain,
  :user_name      => ENV['SENDGRID_USERNAME'],  ## Refer to key SENDGRID_USERNAME
  :password       => ENV['SENDGRID_PASSWORD'],  ## Refer to key SENDGRID_PASSWORD
  :domain         => 'heroku.com',
  :enable_starttls_auto => true
}

在此之后，通过运行以下命令在heroku环境中添加环境变量SENDGRID_USERNAME和SENDGRID_PASSWORD：

heroku addons:add sendgrid:starter

请在production.rb file.config.action\u mailer.default\u url\u options={:host=>'secret-brushlands-1375.herokuapp.com'}中共享操作\u mailer设置。就这些吗？我不这么认为。给我所有以config.action\u mailer开始的配置，比如config.action\u mailer.smtp\u设置。。在问题中更新它。由于我是新手，8小时内无法回答我的问题：不要回答，只需单击问题下方的编辑链接来编辑你的问题。注意用户名和密码键。您的指定不正确。是否执行了以下操作：user\u name=>ENV['SENDGRID\u USERNAME']，：password=>ENV['SENDGRID\u password']？您不应该在此处传递实际用户名和密码。完全按照我的答案复制代码。不要改变价值观。瞧，就是这样——非常感谢你！
