我试图建立一个博客,但由于一个表的迁移错误而被封锁。
我试图更改外键的创建顺序,
仅将两个外键与数组一起构建,
$table->foreign(['commentary_id', 'post_id'])->references(['id', 'post_id'])->on('commentaries');
评论迁移
$table->integer('post_id')->unsigned();
$table->integer('id')->unsigned();
$table->string('content');
$table->integer('user_id')->unsigned();
$table->timestamps();
$table->primary(['post_id', 'id']);
$table->foreign('post_id')->references('id')->on('posts');
$table->foreign('user_id')->references('id')->on('users');
响应迁移
$table->integer('post_id')->unsigned();
$table->integer('commentary_id')->unsigned();
$table->integer('id')->unsigned();
$table->string('content');
$table->integer('user_id')->unsigned();
$table->timestamps();
$table->primary(['post_id', 'commentary_id', 'id']);
$table->foreign(['commentary_id', 'post_id'])->references(['id', 'post_id'])->on('commentaries');
$table->foreign('user_id')->references('id')->on('users');
还有我得到的错误:
General error: 1005 Can't create table `blog-lurius`.`responses`
(errno: 150 "Foreign key constraint is incorrectly formed")
(SQL: alter table `responses` add constraint `responses_commentary_id_post_id_foreign` foreign key (`commentary_id`, `post_id`) references `commentaries` (`id`, `post_id`))
我希望在迁移过程中不会出现致命错误。我的两个外键都有效的地方。
