symfony 数据库表生成实体、迁移数据库

从数据库表生成实体

---

1. 由数据库生成模型：

　　php bin/console doctrine:mapping:convert --from-database yml D:\db\

D:\test_backend>php bin/console doctrine:mapping:convert --from-database yml D:\db\
Processing entity "AppUser"
Processing entity "Channel"
Processing entity "MigrationVersions"

Exporting "yml" mapping information to "D:\db"

　　(模型要改第一行路径，不然在实例表结构时会报错如下：)

　　　Invalid mapping file 'AppBundle.Entity.AppUser.orm.yml' for class 'AppBundle\Entity\AppUser'.

example:

　　app_user表生成的模型第一行为：'AppUser:';要将此改为 “AppBundle\Entity\AppUser:”

2.实例所有表结构

　　表结构文件复制至：AppBundle\Resources\config\doctrine

　　php bin/console doctrine:generate:entities AppBundle/Entity/ --path src/

　　实例单个表结构（SiteChannel）

　　php bin/console doctrine:generate:entities AppBundle/Entity/SiteChannel --path src/ 

D:\test_backend>php bin/console doctrine:generate:entities AppBundle/Entity/AppUser --path src/
Generating entities for namespace "AppBundle\Entity\AppUser"
  > backing up AppUser.php to AppUser.php~
  > generating AppBundle\Entity\AppUser

 数据库迁移(symfony本地迁移到数据库):

---

　　开启数据库迁移：composer require doctrine/doctrine-migrations-bundle "^1.0"

　　实体更新到数据库

　　Resources->Entity

　　(比较)

　　php bin/console doctrine:migrations:diff

　　(迁移)

　　php bin/console doctrine:migrations:migrate
