Question

嘿大家在使用ActiveRecord时遇到问题＆＃39; mysql2＆＃39;宝石。我使用的是rails 4.0.4我的config / application.rb中有这些行

# Pick the frameworks you want: 
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"

当我尝试运行＆＃39; rails g model user＆＃39;我得到

 invoke  active_record
 /Users/edjasper/.rvm/gems/ruby-2.1.1/gems/railties4.0.4/lib/rails/application/configuration.rb:110:in `database_configuration': Could not load database configuration. No such file - /Users/edjasper/Desktop/associations_challenge_8/config/database.yml (RuntimeError

任何建议？

Answer 1

是的，你在config dir中没有database.yml 喜欢

development:
  adapter: mysql2
  encoding: utf8
  database: my_db_name
  username: root
  password: my_password
  host: 127.0.0.1
  port: 3306
  secure_auth: false

你的config dir中也应该有sample.yml.example样本

通过错误信息告诉你的方式：）

No such file - /Users/edjasper/Desktop/associations_challenge_8/config/database.yml
