加盟Laravel多创造？

Question

我想一次在3个至表插入新记录。是否有任何解决方案中使用一个创建或加入三个表？

在SingleController.php：

$single = Single::create([
                    'structure_id' => $request->structure_id,
                    'user_id' => auth()->id(),
                ]);

$structure = Structure::create([
                    'name' => $request->name,
                ]);

$placement = Placement::create([
                    'structure_id' => $request->structure_id,
                    'seed' => $request->seed,
                ]);

在Structure.php的模型：

public function singles()
{
    return $this->hasMany(Single::class);
}

public function placements()
{
    return $this->hasMany(Placement::class);
}

创建Structure后，你可以这样做：

$structure->singles()->create({
    'structure_id' => $request->structure_id,
    'user_id' => auth()->id(),
})

$structure->placements()->create({
    'structure_id' => $request->structure_id,
    'seed' => $request->seed,
})
