如何使用 laravel 5 中的 eloquent 从 3 表中获取一些数据?我有 3 个表,列表,卡片,用户
列出模型
public function card()
{
return $this->hasMany(Card::class);
}
卡片型号
public function lists()
{
return $this->belongsTo(Lists::class);
}
public function member()
{
return $this->belongsToMany(User::class)->withPivot('status','user_role')->withTimestamps();
}
用户模型
public function card_member(){
return $this->belongsToMany(Card::class)->withTimestamps();
}
我想在分配给特定用户的卡片中获取列表(例如 user_id :2)

卡片 :
