How to replace your rails local pg db with the database in production on Heroku?

Question

I have a db locally in my Rails app. The app is alreqady linked to Heroku through git. I want to totally replace my development db with the one in production on Heroku . How do it ? Are there a set of commands I can use locally to do the job for me ?

Answer 1

You can easily do it with help of heroku pg:backups:restore command. see the detail document here . If you do not have any s2 url for dump install ngrok and put your file in public folder and provide that ngrok url of dump. This will help.

Answer 2

There's a Heroku command for that: heroku pg:pull HEROKU_POSTGRESQL_MAGENTA mylocaldb --app sushi , where you replace each of those arguments with your app's information. ( https://devcenter.heroku.com/articles/heroku-postgresql )

You could write a short rake task to fully replace your local db with Heroku using that command:

lib/tasks/db.rake

desc 'replaces local database with Heroku production database'
task replace_local_with_production: :environment do
  Rake::Task['db:drop'].invoke
  system heroku pg:pull HEROKU_POSTGRESQL_MAGENTA mylocaldb --app sushi
  Rake::Task['db:migrate'].invoke
end
