https://github.com/twilio/hurl

我无法通过自述文件中的步骤在 Heroku 上运行服务器。

我做的步骤：

git clone git://github.com/twilio/hurl
cd hurl
gem install bundler
bundle install
heroku create
git push heroku master
heroku open

使用heroku logs我看到连接到的错误PG

"/app/app/models/db.rb:16:in `initialize': could not connect to server: Connection refused (PG::Error)"

请帮助我做错了什么..

更新：

file:`db.rb`
    15      class PostgresDB < AbstractDB
    16        CONN = PG::Connection::new(
    17         ENV.fetch("POSTGRES_HOST", "localhost"),
    18          ENV.fetch("POSTGRES_PORT", 5432), 
    19          :dbname => ENV.fetch("POSTGRES_DATABASE", "hurls"),
    20          :user => ENV.fetch("POSTGRES_USER", "postgres"),
    21          :password => ENV.fetch("POSTGRES_PASSWORD", "postgres")
    22        )

从 postgresql 的配置 heroku 插件服务器更改了详细信息并收到此错误：

有人实现了正常的heroku服务器吗？

使用以下方法添加所有配置变量：

$ heroku config:add POSTGRES_DATABASE=your_database
$ heroku config:add POSTGRES_HOST=your_host
$ heroku config:add POSTGRES_USER=your_user
$ heroku config:add POSTGRES_PASSWORD=your_password
$ heroku config:add POSTGRES_PORT=5432

或在一行中： $ heroku config:add POSTGRES_DATABASE=your_database POSTGRES_HOST=your_host POSTGRES_USER=your_user POSTGRES_PASSWORD=your_password POSTGRES_PORT=5432

否则手动创建表：

$ heroku pg:psql
create table users (id character(40), content bytea);
create table hurls (id character(40), content bytea);

除了由 rails 控制台生成的 config 目录中的文件之外，gemfile 也需要正确编辑才能与 postgresql 一起使用，通常 rails 生成 db.rb 以使用 sqlite3 并且 gemfile 中也提到了相同的 db，它们都需要工作使用 postgresql，因为 heroku 使用 postgres，希望它可能会有所帮助。
