test
category\u post\u pad

添加约束category\u post\u pad\u post id\u Foreign
外键(post\id
)引用posts
(id
)在删除级联上)
迁移:
public function up()
{
Schema::create('category_post_pad', function (Blueprint $table) {
$table->unsignedInteger('category_id');
$table->unsignedInteger('post_id');
$table->foreign('post_id')
->references('id')
->on('posts')
->onDelete('cascade');
$table->unsignedInteger('pad_id');
});
}
posts
id
是迁移中的整数还是bigInteger?如果是bigInteger,则其类型与外键类型之间会有冲突。请修改posts的主键,或更改外键的unsignedBigInteger
,您将在post-ta中使用不同的id数据类型ble和post_id的数据类型为usignedInteger
