使用laravel将数据保存在2个不同的表中

// 创建数据库表
Schema::create('main_table', function (Blueprint $table) {
    $table->increments('id');
    // 添加其他字段
    $table->timestamps();
});

Schema::create('related_table', function (Blueprint $table) {
    $table->increments('id');
    // 添加其他字段
    $table->integer('main_table_id')->unsigned();
    $table->foreign('main_table_id')->references('id')->on('main_table');
    $table->timestamps();
});

// 创建主表模型
class MainTable extends Model
{
    protected $table = 'main_table';

    public function relatedTables()
    {
        return $this->hasMany(RelatedTable::class);
    }
}

// 创建从表模型
class RelatedTable extends Model
{
    protected $table = 'related_table';

    public function mainTable()
    {
        return $this->belongsTo(MainTable::class);
    }
}

// 数据保存
$mainTable = new MainTable;
$mainTable->column1 = 'Value 1';
$mainTable->column2 = 'Value 2';
$mainTable->save();

$relatedTable = new RelatedTable;
$relatedTable->column3 = 'Value 3';
$relatedTable->column4 = 'Value 4';
$mainTable->relatedTables()->save($relatedTable);
