[英]How to create new database on heroku server with postgres
I want to create a PostgreSQL database on a Heroku server. 我想在Heroku服务器上创建一个PostgreSQL数据库。
My database.yml
is 我的
database.yml
是
production:
adapter: postgresql
encoding: utf8
database: ddb
username: postgres
port: 5432
password: admin
host: localhost
When I run heroku rake db:create
it gives me the error: 当我运行
heroku rake db:create
它给我错误:
mydatabase already exists
(in /disk1/home/slugs/181380_8d7032f_f439-4fe4f5a6-f181-4150-a968-fadcf45f0af5/mnt)
I have tried it for various different database names, but get the same message. 我已经尝试了各种不同的数据库名称,但得到相同的消息。
How can I resolve this error? 我该如何解决这个错误?
heroku autogenerates database.yml on the deploy. heroku在deploy上自动生成database.yml 。 Reads like: it doesn't matter what you put in your database.yml, which to me is nice, as I can include it in git without worrying about production db passwords.
读取如下:你放在database.yml中的内容并不重要,这对我来说很好,因为我可以将它包含在git中,而不必担心生成db密码。
You may choose another database by setting the ENV['DATABASE_URL'] (use heroku config:add DATABASE_URL=....
) 你可以通过设置ENV ['DATABASE_URL']来选择另一个数据库(使用
heroku config:add DATABASE_URL=....
)
