Question

现在已经有2个小时了，我一直在努力让邮件工作者在heroku工作。

我在rails上使用ruby并且我的代码工作正常，直到我尝试使用gmail按this指南设置邮件。

我已将这些行添加到我的/config/environments/production.rb：

  config.action_mailer.default_url_options = { :host => 'gigitt.herokuapp.com' }
  Rails.application.routes.default_url_options[:host] = 'gigitt.herokuapp.com'

所有东西都推到了heroku，但是当我尝试：heroku运行rake db：setup 我收到以下错误：

Running `rake db:setup` attached to terminal... up, run.9482
FATAL:  permission denied for database "postgres"
DETAIL:  User does not have CONNECT privilege.

删除这些行后，我收到此错误：

2015-04-30T21:15:21.935684+00:00 app[web.1]: ActionView::Template::Error (Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true):

所以我需要这些线条，但它不会使用它，任何想法？

Answer 1

-SessionVariable尝试创建数据库，你不能使用rake在Heroku上做到这一点。你有一个pg数据库吗？你说你的代码工作正常，直到邮件，所以我猜你做。如果您想运行迁移，只需运行-WebSession。

Answer 2

好的，我把它弄好了。这是我的production.rb：

  config.action_mailer.default_url_options = { :host => 'http://gigitt.herokuapp.com' }
  Rails.application.routes.default_url_options[:host] = 'http://gigitt.herokuapp.com'
  config.action_mailer.delivery_method = :smtp
  # SMTP settings for gmail
  config.action_mailer.smtp_settings = {
   address:               "smtp.gmail.com",
   port:                  587,
   domain:                ENV["GMAIL_DOMAIN"],
   authentication:        "plain",
   enable_starttls_auto:  true,
   user_name:             ENV['GMAIL_USERNAME'],
   password:              ENV['GMAIL_PASSWORD']
  }
end

我的.env：

GMAIL_DOMAIN=mail.website.com.com
GMAIL_USERNAME=email@website.com
GMAIL_PASSWORD=password

我将提交推送到heroku，没有运行heroku运行rake db：setup而不是运行heroku运行rake db：migrate。现在一切正常:-D

Heroku权限被拒绝用于数据库“postgres”
