在将数据插入 mysql 数据库时，我收到下面的错误，并且根据之前关于 stackoverflow 的一些问题的答案，我将 protected $fillable 放在我的模型文件中但仍然显示错误。
当我创建我的第一个条目表时它接受没有任何错误但是当我创建我的新条目时它显示错误。
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`app`.`articles`, CONSTRAINT `articles_ibfk_1` FOREIGN KEY (`article_id`) REFERENCES `users` (`id`)) (SQL: insert into `articles` (`article_head`, `article_body`) values (abkskfbasfbv, zbfvaksdvaskdvjsdc
))
文章.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Article extends Model
{
protected $fillable = [
'article_head', 'article_body',
];
public $timestamps = false;
}
迁移文件
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
class CreateArticlesTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('articles', function(Blueprint $table)
{
$table->increments('article_id');
$table->string('article_head', 500);
$table->string('article_body', 10000);
$table->dateTime('created_on');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('articles');
}
}

<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
class AddForeignKeysToArticlesTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::table('articles', function(Blueprint $table)
{
$table->foreign('article_id', 'articles_ibfk_1')->references('id')->on('users')->onUpdate('RESTRICT')->onDelete('RESTRICT');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::table('articles', function(Blueprint $table)
{
$table->dropForeign('articles_ibfk_1');
});
}
}
最佳答案
放
protected $primaryKey = "article_id";
在您的文章模型中。
