ruby-on-rails - 数据库 "postgres"的 Heroku 权限被拒绝

Question

现在 2 个小时，我一直在尝试让邮件程序在 heroku 中工作。

我在 Rails 上使用 ruby​​，我的代码工作正常，直到我尝试根据 this 设置带有 gmail 的邮件程序指导。

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

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

一切都很好地推送到 heroku 但当我尝试时: 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，出现此错误:

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，但它无法使用，有什么想法吗？

Answer 1

rake db:setup 尝试创建数据库，您不能在 Heroku 上使用 rake 执行此操作。你创建了 pg 数据库吗？你说你的代码在邮寄之前工作正常，所以我猜你是这样的。如果你想运行迁移，只需运行 rake db:migrate。
