Rails＆Heroku：PG db无法创建数据库
我几乎已经阅读了关于部署到heroku的每个问题和文档，这不是我的第一次，但现在在我部署的一个非常奇怪的scnario我无法创建数据库：
Running `rake db:create --trace` attached to terminal... up, run.8982 ** Invoke db:create (first_time) ** Invoke db:load_config (first_time) ** Execute db:load_config ** Execute db:create FATAL: permission denied for database "postgres" DETAIL: User does not have CONNECT privilege. /app/vendor/bundle/ruby/1.9.1/gems/activerecord-4.1.2/lib/active_record/connection_adapters/postgresql_adapter.rb:888:in `initialize' /app/vendor/bundle/ruby/1.9.1/gems/activerecord-4.1.2/lib/active_record/connection_adapters/postgresql_adapter.rb:888:in `new' . . . .

FactoryGirl搞砸了rake db：迁移过程
我拿出与Factory girl相关的所有东西，spec文件中的所有内容。

Heroku上的Rails 4.0.1，无法创建数据库
这是我的gemfile：

在我的Heroku Logs中，这是我发现的：

非常感谢任何帮助。
我遇到的这个问题很难吸取教训，但首先让我们回答，然后解释发生了什么。
简短回答：
尽管删除了被认为导致耙子破裂的测试，但还有其他一些需要删除的东西，这导致了问题：
1-在application.rb中发生这种情况：
config.generators do |g| g.test_framework :rspec, fixtures: true, view_specs: false, helper_specs: false, routing_specs: false, controller_specs: false, request_specs: false g.fixture_replacement :factory_girl, dir: "spec/factories" end
2-在seed.rb文件中发生了这种情况：
# user = CreateAdminService.new.call # puts 'CREATED ADMIN USER: ' << user.email
课程：
1-不要使用自动应用程序生成器。 就我而言，我使用的是#RailsComposer。
2 Bower on Rails是一个糟糕的决定，它可以将一个非常简单的应用程序变成一个疯狂的amazin丛林
