在Heroku上使用Postgresql的Dancer2应用程序

我正在尝试部署一个在Heroku上使用Postgresql的小型Dancer2应用程序 . 到目前为止,我试图接近:a)我输入了 heroku addons:add heroku-postgresql 手工创建的所有表,并授予我在heroku数据库连接设置中找到的默认所有者的权限 . 然后我将以下连接设置添加到我的config.yml文件中:

DBIC:
     d1ofgde:
       dsn:  'dbi:Pg:dbname=d1ofgde'
       user: 'ygcexhxtprm'
       password: 'izU2xTVDfd5T5Byy4M4Xhk'
       host: 'ec2-54-244-50-186.compute-1.amazonaws.com'
       port: 5432
       options:
         RaiseError: 1
         PrintError: 1
       schema_class: 'My::Schema

这失败了 .

b)我尝试使用以下命令在heroku上推送我的本地postgres数据库:

PGUSER=test PGPASSWORD=test heroku pg:push mytestdb DATABASE_URL postgres://ygcexmzlhxtprm:izU2xTVDfd5RekzT5Byy4M4Xhk@ec2-54-243-50-185.compute-1.amazonaws.com:5432/d1ofgdng49tf0e --app  lit-mesa-10053

推手一个错误:

:pg_restore: [archiver (db)] could not execute query: ERROR:  must be owner of extension plpgsql
    Command was: COMMENT ON EXTENSION plpgsql IS 'PL/pgSQL procedural language

但当我登录我的heroku postgres时,我看到里面的 table .

在这两种情况下,我在config.yml中为我的连接设置使用了相同的结构 . 并得到相同的错误消息:

    所以我用这个代码修复了我的错误:在myapp.pm中,我添加了以下行:

    my $env_url = $ENV{MYAPP_DB_DSN};
        my $env_user = $ENV{MYAPP_DB_USERNAME};
        my $env_password = $ENV{MYAPP_DB_PASSWORD};
    my $schema = My::Schema->connect("$env_url;user=$env_user;password=$env_password");
    

    然后用 heroku config:set 我给了值

    MyAPP_DB_DSN='dbi:Pg:dbname=mydb; host=myherokuhost'; port=5432'
    MYAPP_DB_USERNAME=myusername  
    MYAPP_DB_PASSWORD=mypass
    

    它现在有效
