ruby - Rails development logging - Rails.logger filename nil? -

i'm having trouble logging in development environment.

here's rails.logger looks like:

loading development environment (rails 3.2.13) irb(main):001:0> rails.logger => #<activesupport::taggedlogging:0x007fe83533caa0 @logger=#<logger:0x007fe83533cc30 @progname=nil, @level=1, @default_formatter=#<logger::formatter:0x007fe83533cbe0 @datetime_format=nil>, @formatter=#<logger::simpleformatter:0x007fe83533caf0 @datetime_format=nil>, @logdev=#<logger::logdevice:0x007fe83533cb90 @shift_size=nil, @shift_age=nil, @filename=nil, @dev=#<io:/dev/ttys023>, @mutex=#<logger::logdevice::logdevicemutex:0x007fe83533cb68 @mon_owner=nil, @mon_count=0, @mon_mutex=#<mutex:0x007fe83533cb18>>>>> irb(main):002:0> 

my log directory permissioned 755:

drwxr-xr-x    7 manderson  staff   238b oct  4 15:17 log 

here's contents of /log directory looks like:

$ ls -lah log/ total 32 drwxr-xr-x   7 manderson  staff   238b oct  4 15:17 . drwxr-xr-x@ 23 manderson  staff   782b oct  4 15:38 .. -rw-r--r--   1 manderson  staff     0b aug 26 13:23 .gitkeep -rw-rw-rw-   1 manderson  staff     0b oct  4 15:38 development.log -rw-r--r--   1 manderson  staff    13k oct  7 10:43 newrelic_agent.log -rw-r--r--   1 manderson  staff     0b oct  4 15:38 production.log -rw-rw-rw-   1 manderson  staff     0b oct  4 15:38 test.log 

as can see, development.log file permissioned correctly (i think), rails.logger doesn't have log/development.log set properly.

any idea why happening? in advance.

edit: here's config/environment/development.rb:

myappname::application.configure   # settings specified here take precedence on in config/application.rb    # in development environment application's code reloaded on   # every request. slows down response time perfect development   # since don't have restart web server when make code changes.   config.cache_classes = false    # log error messages when accidentally call methods on nil.   config.whiny_nils = true    # show full error reports , disable caching   config.consider_all_requests_local       = true   config.action_controller.perform_caching = false   config.cache_store = :dalli_store    # don't care if mailer can't send   config.action_mailer.raise_delivery_errors = false    # print deprecation notices rails logger   config.active_support.deprecation = :log    # use best-standards-support built browsers   config.action_dispatch.best_standards_support = :builtin    # raise exception on mass assignment protection active record models   # config.active_record.mass_assignment_sanitizer = :strict    # log query plan queries taking more (works   # sqlite, mysql, , postgresql)   # config.active_record.auto_explain_threshold_in_seconds = 0.5    # not compress assets   config.assets.compress = false    # expands lines load assets   config.assets.debug = true    config.log_level = :debug  end 

edit 2: here's application.rb. sorry post getting lengthy, reading :)
