Hi there,
I’m picking up this conversation from Al here.
All the details to solve this have been provided in this thread - it’s important to note that this is not a Render-specific issue; this is an application configuration issue.
Configuring Rails to use a database follows a similar pattern across most providers, a database.yml with a production attribute and the URL attribute set to use the environment variable eg:
production:
<<: *default
url: <%= ENV['DATABASE_URL'] %> # ENTER THIS *EXACTLY* AS THIS, THIS READS THE VALUE OF THE DATABASE_URL environment variable programatically
And then provided you have DATABASE_URL set as an environment variable to a valid postgres connection string at runtime the Rails application will point at the correct database.
