Postgres on Rails FATAL: database does not exist
I was having a similar problem.I checked different websites and tried what they suggested but didn't work.Then I tried what you suggested.rake db:create:all and rake db:migrate it worked for me. Thank you!
You need to create the databases first. Run rake db:create:all
Also make sure your yml file is set up correctly for postgres.
db:create:all and db:migrate did not work for me first.I changed my database name from development.pg to developmentpg in myapp/config/database.yml file:
database: db/developmentpg
and then rake db:create:all and rake db:migrate, it worked for me.
Thank you
