Rails not using Postgres user account -

-

i'm using rails 3.0 , postgresql 8.4 on ubuntu 10.10 , ruby 1.9.2p136 pg gem. when run rake db:migrate, error fatal: password authentication failed user "my_os_user_account", when expected log in database my_db_username specified in database.yml.

i have md5 authentication configured in pg_hba.conf both unix socket , ip connections , can log in using psql on command line. have tried setting authentication trust. psql allows me log in without entering password, rails gives fatal: role "my_os_user_account" not exist.

here's database.yml:

development:   adapter: postgresql   database: my_project_dev   user: my_db_username   password: my_password   pool: 5   timeout: 5000

with additional near-identical entries test , production.

the correct key username is, in fact, username , not user. easy mistake, easy fix.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
