我正在开发一个新的RoR应用程序，我一直在接收fe_sendauth：创建新数据库时没有提供密码。我已经尝试安装并重新安装postgresql而没有任何变化。

# PostgreSQL. Versions 8.2 and up are supported.
#
# Install the pg driver:
# gem install pg
# On OS X with Homebrew:
# gem install pg -- --with-pg-config=/usr/local/bin/pg_config
# On OS X with MacPorts:
# gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
# On Windows:
# gem install pg
# Choose the win32 build.
# Install PostgreSQL and put its /bin directory on your path.
#
# Configure Using Gemfile
# gem 'pg'

encoding: unicode
# For details on connection pooling, see rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: 5
development:
<<: *default
database: dearMe_development
# The specified database role being used to connect to postgres.
# To create additional roles in postgres see `$ createuser --help`.
# When left blank, postgres will use the default role. This is
# the same name as the operating system user that initialized the database.
#username: dearMe
# The password associated with the postgres role (username).
#password:
# Connect on a TCP socket. Omitted by default since the client uses a

# The TCP port the server listens on. Defaults to 5432.
# If your server runs on a different port number, change accordingly.

# Schema search path. The server defaults to $user,public

# Minimum log levels, in increasing order:

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is

#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
# DATABASE_URL="postgres://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
# production:
# url: <%= ENV['DATABASE_URL'] %>
#
production:
<<: *default
database: dearMe_production
username: dearMe
password: <%= ENV['DEARME_DATABASE_PASSWORD'] %>
我相信我可以在database.yml中设置密码和用户名，但是我将它们设置为什么？
答案 0 :(得分：1)
您必须为您的数据库添加密码，您的database.yml应该看起来像这样
/**
* Parse long itrative tags
*
* Return array of matches for iterative tag pattern e.g. {%label%} to output the document label on this iteration of the loop
*
* @access public
* @return array
*/
function parse_long_iterative_tags($text)
{
$pattern = "/{%(?P<type>[A-Za-z0-9_?!]+):\((?P<name>.+)\)[\s]*(?P<attributes>[A-Za-z0-9\s_,:?.\/\-\|\(\)]*?){[\s]*(?P<content>(.*?[\s]*)*)[\s]*\}[\s]*end\\1\%}/";
preg_match_all($pattern,$text,$matches);
if(!empty($matches['content'])):
$nested = implode("",$matches['content']);
$sub_matches = $this->parse_long_iterative_tags($nested);
foreach($matches as $k=>$v):
$matches[$k] = array_merge($matches[$k],$sub_matches[$k]);
endforeach;
return $matches;
else:
return $matches;
endif;
return $matches;
}
答案 1 :(得分：0)
您应将password添加到您的database.yml
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: 5
host: localhost
port: 5432
username: postgres
password: postgres
您可以使用默认密码或创建另一个here。
