Answer 1

您可以编写一个脚本，将当前数据库移植到种子文件中，然后使用heroku run rake db:seed种子文件。

Answer 2

First dump your local database to a dump file:

PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U myuser mydb > mydb.dump

Replace myuser , mypassword , and mydb with your username, password and database name. If there is no password set, leave out the PGPASSWORD=mypassword part.

Next, you must place the mydb.dump file in a publicly accessible location, so upload it to an FTP server or Amazon S3 bucket (for example).

Then on your local machine run:

heroku pg:backups restore 'https://s3.amazonaws.com/me/mydb.dump' HEROKU_POSTGRESQL_COLOR_URL -a appname

Replace HEROKU_POSTGRESQL_COLOR_URL with the URL for your app's database. If you don't know the URL, you can find it with heroku config | grep HEROKU_POSTGRES heroku config | grep HEROKU_POSTGRES . Replace https://s3.amazonaws.com/me/mydb.dump with the URL where you uploaded the dump file. Replace appname with name of your app as defined in Heroku.
