我知道已经有几个类似的帖子,但他们没有给我我需要的答案。所以,我正在使用Phinx,并试图添加一个外键,但我得到了以下错误:
General error: 1215 Cannot add foreign key constraint下面是包含外键的php文件:
<?php
use Phinx\Migration\AbstractMigration;
class CustomQuotes extends AbstractMigration
{

public function change()
{
$table = $this->table('custom_quotes', ['id' => false, 'primary_key' => ['custom_quote_id']]);
$table->addColumn('custom_quote_id', 'biginteger', ['identity' =>true, 'signed' => false])
->addColumn('account_id', 'biginteger', ['limit' => 20, 'null' => true])

->addForeignKey('quote_type_id', 'quote_types', 'quote_type_id', array('delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION'))
->create();
}
}我尝试从中获取id的两个表是在上面的表之前创建的。下面是另外两个表:
报价类型表

所以我想通了。原来,我必须在custom_quotes表中使我的account_id和quote_type_id未签名,因为我在accounts和quote_type表中使它们未签名。现在说得通了。以下是解决方案:
<?php
use Phinx\Migration\AbstractMigration;
class CustomQuotes extends AbstractMigration
{
/**
* Change Method.
*
* Write your reversible migrations using this method.
*
* More information on writing migrations is available here:
* http://docs.phinx.org/en/latest/migrations.html#the-abstractmigration-class
*
* The following commands can be used in this method and Phinx will
* automatically reverse them when rolling back:
*
* createTable
* renameTable
* addColumn
* renameColumn
* addIndex
* addForeignKey
*
* Remember to call "create()" or "update()" and NOT "save()" when working
* with the Table class.
