轨道/ ActiveRecord的 - AdapterNotSpecified，即使它是 [英] Rails / ActiveRecord - AdapterNotSpecified, even though it is

问题描述

我做的 Ruby on Rails的教程。，在前三章它使用SQLite的，但后来却建议在使用PostgreSQL开发更容易的Heroku部署。编辑后，我的的database.yml 和的Gemfile 来使用PG，而不是sqlite3的，似乎工作 - 用耙时除外运行测试。它弹出一个 AdapterNotSpecified 错误。

I'm doing the Ruby on Rails Tutorial. For the first three chapters it uses SQLite, but later it suggests using PostgreSQL on development for easier Heroku deploys. After editing my database.yml and Gemfile to use pg instead of sqlite3, it seems to work - except when using Rake to run a test. It pops out an AdapterNotSpecified error.

C：/Ruby/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/activerecord-4.0.0/lib/active_record/ connection_adapters / connection_specification.rb：52：在resolve_hash_connection：  数据库配置不指定适配器（的ActiveRecord :: AdapterNotSpecif IED）

C:/Ruby/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/activerecord-4.0.0/lib/active_record/ connection_adapters/connection_specification.rb:52:in resolve_hash_connection': database configuration does not specify adapter (ActiveRecord::AdapterNotSpecif ied)

等。

在database.yml中指定一个适配器，像这样：

The database.yml specifies an adapter, like so:

development:
  adapter: postgresql
  host: localhost
  username: nekkoru
  password: derpderp
  database: development
  encoding: UTF8

这是怎么回事？我在Windows 7 64位系统，红宝石1.9.3，Rails的4.0.0，PostgreSQL的9.3.0.1。

What's going on? I'm on Windows 7 x64, Ruby 1.9.3, Rails 4.0.0, PostgreSQL 9.3.0.1.

推荐答案

您没有定义数据库的测试环境。您的database.yml 应该是这样的：

You did not define the database for the test environment. You database.yml should look like:

development:
  adapter: postgresql
  host: localhost
  username: nekkoru
  password: derpderp
  database: development
  encoding: UTF8

test:
  adapter: postgresql
  host: localhost
  username: nekkoru
  password: derpderp
  database: test        # or whatever the name is
  encoding: UTF8
