Rake tasks seem to ignore database.yml configuration

Question

I am using MAC OS X along with postgresql installed via Homebrew. I am developing using Rails 4.2.1 and ruby 2.2.0. The connection with postgresql server is fine but for some reason every application accesses the database "kstavrou" which is my system username, as a development database and creates the rest as defined by database.yml. That is troublesome if you have more than 1 rails app.

rake db:create output:

Konstantinoss-MacBook-Pro:ecomm-intel kstavrou$ rake db:create
kstavrou already exists
ecomm_intel_test already exists

strange thing is that if I empty database.yml still connects fine to postgresql and tries to create again the database "kstavrou" executing there all the migrations, without trying to create the test database. rake db:create output:

Konstantinoss-MacBook-Pro:ecomm-intel kstavrou$ rake db:create
kstavrou already exists

database.yml

default: &default
adapter: postgresql
host: localhost
encoding: utf8
username: pguser
password: 123456
pool: 5
production:
<<: *default
database: ecomm_intel_prod
development:
<<: *default
database: ecomm_intel_dev
test:
<<: *default
database: ecomm_intel_test

Answer 1

Well the problem was that the ENV['DATABASE_URL'] was set (by some install script) so it was overwriting the database.yml configuration, as noted by steve klein, so I just removed it.

`export DATABASE_URL=postgres:///$(whoami)`
