我尝试执行cli命令./doctrine generate-migrations-diff,并在正确的文件夹中正确创建了一个版本文件。
消息是: generate-migrations-diff - 从差异中成功生成的迁移类
然后我尝试执行另一个cli命令./doctrine migrate并向我显示一条消息: migrate - 成功迁移到版本#1 ,但是当我打开该类时,任何修改都已完成。为什么呢?
这是version1文件:
<?php
class Version1 extends Doctrine_Migration_Base
{
public function up()
{
$this->removeColumn('addresses', 'address_test');
}
public function down()
{
$this->addColumn('addresses', 'address_test', 'string', '', array(
'fixed' => '0',
'unsigned' => '',
'primary' => '',
'notnull' => '1',
'autoincrement' => '',
));
}
}
?>
这是YAML。 我删除了字段:address_test
Addresses:
connection: doctrine
tableName: addresses
columns:
address_id:
type: integer(4)
fixed: false
unsigned: false
primary: true
autoincrement: true
address:
type: string()
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
city:
type: string(150)
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
code:
type: string(20)
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
country_id:
type: integer(4)
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
base:
type: integer(1)
fixed: false
unsigned: false
primary: false
default: '0'
notnull: true
autoincrement: false
latitude:
type: string(20)
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
longitude:
type: string(20)
fixed: false
unsigned: false
primary: false
notnull: false
autoincrement: false
customer_id:
type: integer(4)
fixed: false
unsigned: false
primary: false
notnull: true
autoincrement: false
这是迁移命令生成的BaseAddresses类: bindComponent('Addresses','doctrine');

在某些网站上我已经读过我必须执行命令: build-all 以生成更新类地址的版本,但是我收到此错误:
SQLSTATE[HY000]: General error: 1005 Can't create table 'web63db1.#sql-3e6_11d' (errno: 121). Failing Query: "ALTER TABLE addresses ADD CONSTRAINT addresses_customer_id_customers_customer_id FOREIGN KEY (customer_id) REFERENCES customers(customer_id) ON DELETE CASCADE". Failing Query: ALTER TABLE addresses ADD CONSTRAINT addresses_customer_id_customers_customer_id FOREIGN KEY (customer_id) REFERENCES customers(customer_id) ON DELETE CASCADE
我做了什么?提前谢谢。
答案 0 :(得分:7)
迁移仅用于更改数据库,而不用于更改模型类。您需要在之后构建模型类。
所以你的正常工作方式是:
答案 1 :(得分:1)
由于我无法评论,让我修改Timo的答案:
我强烈建议您在首次运行任何迁移之前备份数据库。如果迁移失败(即因为您的架构错误),您最终可能会遇到一个在迁移之间陷入困境的数据库,需要报废。我通常,备份我的test-db然后导入实时数据库以测试迁移。对于在实时服务器上迁移失败,我有点害怕。
重要的是要注意'doctrine:generate-migrations-diff'将schema.yml与当前生成的类文件进行比较。 在生成迁移之前不要构建类
要在服务器上部署,您需要上传schema.yml和新的迁移文件。然后做第3步和第3步4(然后根据习惯清除你的缓存),你很高兴。
