Accessing database configuration with Rails
Database configuration can be access via Rails.configuration object:
Rails.configuration.database_configuration[Rails.env]
#> {"adapter"=>"sqlite3", "pool"=>5, "timeout"=>5000, "database"=>"db/development.sqlite3"}
Rails.env can be replaced with any of the available environments, i.e.:
Rails.configuration.database_configuration["development"]
#> {"adapter"=>"sqlite3", "pool"=>5, "timeout"=>5000, "database"=>"db/development.sqlite3"}
