数据库“postgres”的 Heroku 权限被拒绝答案

【问题标题】：Heroku permission denied for database "postgres"数据库“postgres”的 Heroku 权限被拒绝

【问题描述】：

现在 2 小时以来，我一直在尝试让邮件程序在 heroku 中工作。

我正在使用 ruby on rails 并且我的代码运行良好，直到我尝试按照 this 指南设置带有 gmail 的邮件程序。

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'

一切都很好，但是当我尝试时：heroku run 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，我会收到此错误：

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，但它不能用它，有什么想法吗？

【问题讨论】：

尝试 pg:setup 而不是 db
不知道如何构建任务 'pg:setup' 是我得到的错误
为什么要运行 db:setup？ Heroku 不允许你创建这样的数据库。

标签： ruby-on-rails ruby postgresql ruby-on-rails-4 heroku

【解决方案1】：

rake db:setup 尝试创建数据库，但您不能在 Heroku 上使用 rake 执行此操作。您是否创建了 pg 数据库？你说你的代码在邮寄之前运行良好，所以我猜你会的。如果你想运行迁移，只需运行rake db:migrate。

【讨论】：

是的，数据库运行良好。我似乎无法让该应用程序用于电子邮件恢复，这似乎破坏了它。
对，但你为什么要运行 db:setup？是什么告诉你这样做的？这与电子邮件有什么关系？
什么都没告诉我，我之前刚做过，从来没有遇到过问题。我什至创建了一个新应用程序但没有运行 db:setup 并且没有运气
它可以在本地工作，但不能在 heroku 上工作。你有迁移吗？如果没有，您是否尝试过更改电子邮件？这似乎不是问题。

【解决方案2】：

好的，我得到了它的工作。这是我的生产.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 run rake db:setup，而是运行了heroku run rake db:migrate。现在一切正常：-D
