Question

Can't connect droplet with cluster database | Rails|

Hi guys im new in Digital Ocean and im trying to deploy a personal project. My issue happens when i try to migrate into a production database in a droplet rails app

This is my database.YML

  • default: &default

  • adapter: postgresql

  • encoding: unicode

  • pool: <%= ENV.fetch(“RAILS_MAX_THREADS”) { 5 } %>

  • production:

  • <<: *default

  • secret_key_base: <%= ENV[“SECRET_KEY”] %>

  • username: <%= ENV[“DATABASE_USER”] %>

  • password: <%= ENV[“DATABASE_PASSWORD”] %>

  • database: <%= ENV[“DATABASE”] %>

  • host: <%= ENV[“DATABASE_HOST”] %>

these are the steps im following

  1. Cd Into rails app on VM
  2. rails s -d -b 0.0.0.0 RAILS_ENV=production

At this point the production server is “online”

then i want to get migrations by running this:

  1. rake db:migrate RAILS_ENV=production

and this is the issue:

Caused by:PG::ConnectionBad: FATAL: database “root” does not exist

Rails -v 6.0.3.4

Ruby -v 2.7.1

Hi there,

The error that you are getting indicates that you’ve defined root as the database that you want to use, but that database does not seem to exist.

What I could suggest is:

  • Connect to your Managed database with any SQL client like Table Plus or DBever.
  • Create a new database for your project.
  • Then use that new database in your env variables.

For more information on how to do that you can follow the steps here:

Best,

Bobby
