mysql - 尝试在 Windows 中使用 mysql 5.7.1 和 Rails 5 配置数据库时出现“未找到事件记录”错误

Question

我是 RAILS 和 RUBY 的新手。我正在尝试创建一个演示项目来练习。当我尝试使用 RAILS 配置 mysql 数据库时，出现以下错误:

C:\Sites\simple_cms>rake db:schema:dump
rake aborted!
ActiveRecord::AdapterNotSpecified: 'development' database is not configured. 
Available: ["default", "adapter", "pool", "timeout", "database", "username", 
"password", "host"]

Tasks: TOP => db:schema:dump => db:load_config
(See full trace by running task with --trace)

下面是我的database.yml文件内容

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
  default: &default
  adapter: mysql
  pool: 5
  timeout: 5000
  database: simple_cms_development
  username: dumdum 
  password: dumdum
  host: localhost

development:
  <<: *default  

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default
  database: db/production.sqlite3

我尝试在线搜索，但没有得到明确的帮助。我在 WINDOWS 10 上运行 RAILS

Answer 1

在使用 rake db:schema:dump 之前，您必须创建数据库，然后创建表，

为您的项目创建数据库

rake db:create

创建表

rake db:migrate

在此之后，您可以使用 rake db:schema:dump 检查表架构
