我是RoR的新手,并遵循Michael Hartl的RoR 3.2教程.

在执行第一次测试时(第3.2.1章),RSpec返回一百
从这一个开始的错误(并且所有看起来相同或更多
减)：

/home/fred/.rvm/gems/ruby-1.9.3-p0@ODQ/gems/activerecord-3.2.1/lib/active_record/connection_adapters/abstract/connection_specification.rb:45:in
`resolve_hash_connection': database configuration does not specify
adapter (ActiveRecord::AdapterNotSpecified)

我的DEV数据库是Postgresql,看起来工作正常(迁移工作正常).

有人可以帮我理解什么是错的并解决它吗？

谢谢.

的Gemfile：

source 'https://rubygems.org'

gem 'rails','3.2.1'

# Bundle edge Rails instead:
# gem 'rails',:git => 'git://github.com/rails/rails.git'

gem 'postgres-pr'
gem 'pg'

# gem for test scripts
group :development,:test do 
gem 'rspec-rails'
end

group :test do
  gem 'capybara','1.1.2'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails','~> 3.2.3'
  gem 'coffee-rails','~> 3.2.1'
  gem 'uglifier','>= 1.0.3'
end

gem 'jquery-rails'

database.yml的：

# Postgresql 8.4

  adapter: postgresql
