我已经尝试执行 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 - Generated migration classes successfully from difference

然后我尝试执行另一个 cli 命令 ./doctrine migrate，我看到一条消息:migrate - 已成功迁移到版本 #1 但是当我打开类(class)时，任何修改都已完成。为什么？

这是版本 1 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。 我已经删除了字段: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 migrate 命令生成的 BaseAddresses 类: bindComponent('地址', ' Doctrine ');

在某些网站上，我读到我必须执行命令:build-all 以生成类地址的更新版本，但我收到此错误:

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？提前致谢。

最佳答案

迁移仅用于更改您的数据库，而不是您的模型类。之后您需要构建模型类。

所以你的正常工作方式是:

1. 更改您的 schema.yml
2. 创建您的迁移文件 (generate-migrations-diff)
3. 对数据库运行迁移(迁移)，您的数据库现在应该已更改
4. 更新您的模型类(build-all)

关于php - Doctrine generate-migrations-diff 和 migrate，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3059997/
