Rails & Heroku：PG db 无法创建数据库

Question

我几乎阅读了关于部署到 heroku 的所有问题和文档，这不是我第一次，但现在在部署时出现了一个非常奇怪的问题：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'
.
.
.
.
Couldn't create database for {"adapter"=>"postgresql", "host"=>"ec2-23-23-244-144.compute-1.amazonaws.com", "encoding"=>"unicode", "database"=>"d80e387p61nnl1", "pool"=>5, "template"=>"template0", "username"=>"******", "password"=>"********", "port"=>5432}

不是这样的：

FactoryGirl screws up rake db:migrate process

我几乎把所有与工厂女孩有关的东西都拿出来了，一切都在规范文件中。

也不是这个：

Rails 4.0.1 on Heroku, can't create database

非常感谢任何帮助。

Answer 1

从我遇到的这个问题中可以吸取的教训很少，但首先让我们回答，然后解释发生了什么。

简答：

尽管删除了被认为会导致 rake 损坏的测试，但还有其他需要删除的东西被遗漏了，这会导致问题：

1- 在application.rb这发生了：

 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

教训：

1- 不要使用自动应用生成器。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亚马逊丛林
