EDIT: Lời khuyên chung là sử dụng CEDAR ngăn xếp.Heroku on Rails - Không hợp lệ DATABASE_URL
Khá mới đối với RoR, Gems, Heroku và Git. Làm theo hướng dẫn: http://ruby.railstutorial.org/book/ruby-on-rails-tutorial
trình trơn tru trên localhost, khi triển khai tới Heroku có ConnectionNotEstablished lỗi, mà đã được giải quyết ở đây: https://stackoverflow.com/questions/7542745/heroku-error-activerecordconnectionnotestablished(BTW: sau cùng hướng dẫn) Sau khi thay đổi cơ sở dữ liệu sản xuất để PostgreSQL (đá quý 'pg ') nó tạo ra một lỗi:
cách truy cập vào trang web hoạt động
An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details.
Cố gắng này - Heroku app crashed, receiving "Invalid DATABASE URL" when attempting heroku rake db:migrate - Heroku rake db: di chuyển
rake aborted!
Invalid DATABASE_URL
Tasks: TOP => db:migrate => db:load_config
(See full trace by running task with --trace)

BUNDLE_WITHOUT => phát triển: test LANG => en_US.UTF-8 RACK_ENV => sản xuất Di chuyển sang tuyết tùng, như đề xuất trong câu trả lời khác nữa. –
Di chuyển đến tuyết tùng không phải là tầm thường, một số vấn đề với postgre/sqlite Thời gian tới sẽ sử dụng ** - database = postgresql ** ngay từ đầu. Dù sao nhờ giúp đỡ, bây giờ tôi sẽ hoàn thành hướng dẫn mà không cần triển khai ... –
Đó là thiếu URL cơ sở dữ liệu .... bạn có cơ sở dữ liệu được chia sẻ thêm vào cài đặt không? Nó sẽ nhổ ra URL cơ sở dữ liệu và bên dưới URL cơ sở dữ liệu được chia sẻ. Nếu có vấn đề, có vẻ như nó ở đó. Nên có ít nhất một giá trị mặc định. –
