Up until now I have only used database.yml
with each parameter called out explicitly, in the file below it uses some characters I do not understand. What does each line and symbol(&
, *
, <<
) mean? How do I read this file?
development: &default
adapter: postgresql
database: dev_development
test: &test
<<: *default
database: test_test
cucumber:
<<: *test
production:
<<: *default
database: test_production
