How to resolve the error 'fe_sendauth: no password supplied' in Rails using PostgreSQL? -

i've tried create rails app postgresql database, when started rails server, got error:

fe_sendauth: no password supplied

here're actions step step:

$ sudo apt-get install postgresql postgresql-contrib $ gem install pg $ rails new timetracker --database=postgresql --skip-unit-test 

my database.yml file looks this:

default: &default   adapter: postgresql   encoding: unicode   pool: 5   host: localhost   username: postgres   password:  development:   <<: *default   database: timetracker_development  test:   <<: *default   database: timetracker_test  production:   <<: *default   database: timetracker_production 

and here's pg_hba.conf file:

# database administrative login unix domain socket local               postgres                                peer  # type  database        user            address                 method  # "local" unix domain socket connections local                                                   peer # ipv4 local connections: host                            127.0.0.1/32            md5 # ipv6 local connections: host                            ::1/128                 md5  # modified me. host                            127.0.0.1/32            trust  host                            127.0.0.1/32            trust  host                            ::1/128                 trust 

so, when rails server error , here's doing this:

$ rails c $ activerecord::base.connection.instance_variable_get(:@config) 

2.1.5 :001 > activerecord::base.connection.instance_variable_get(:@config) pg::connectionbad: fe_sendauth: no password supplied
