Laravel更新关系表不起作用

Question

问题1：无法更新关系表profiles的记录。最终出现以下错误。

错误

Illuminate \ Database \ QueryExceptionSQLSTATE [42S22]：找不到列：1054“字段列表”中的未知列“ user_id”（SQL：更新users设置为user_id = 132，users。updated_at = 2020-03-30 08:48 ：51其中id = 132）

我有两个具有以下架构的表users和profiles

用户架构

Schema::create(
    'users',
    function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('username')->unique();
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password')->nullable();
        $table->enum('role', ['super', 'admin', 'manager', 'subscriber', 'user'])->default('user');
        $table->boolean('is_root')->default(FALSE);
        $table->rememberToken();
        $table->timestamps();

        $table->unique(['username', 'email'], 'users_unique_credentials');
    }
);

配置文件架构

Schema::create('profiles', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->bigInteger('user_id')->unsigned();
    $table->string('key', 191);
    $table->longText('value')->nullable();

    $table->foreign('user_id', 'profile_uid_fk')
          ->references('id')
          ->on('users')
          ->onDelete('cascade');

    $table->unique(['user_id', 'key'], 'profile_unique_key');
});

用户模态-关系

public function profiles()
{
    return $this->hasMany(Profile::class)->orderBy('id');
}

个人资料模态-关系

public function user()
{
    return $this->belongsTo(User::class);
}

用户控制器-更新

public function update(UserRequest $request, User $user)
{

    $user->email = $request->email;
    $user->role  = $request->role;

    if ($request->has('password')) {
        $user->password = Hash::make($request->password);
    }

    $user->save();
    $user->profile()->save($user);

}

dd-$ request-> all（）

问题2： user_id是表单中的隐藏字段。但是，我宁愿从控制器传递它。有没有方式吗？

array:15 [▼
  "_token" => "O3Ardvzz7QvAsYa7aUWn4dbJx1qpCsScykD1fh1S"
  "_method" => "PUT"
  "email" => "[email protected]"
  "password" => null
  "password_confirmation" => null
  "role" => "subscriber"
  "first_name" => "John"
  "last_name" => "doe"
  "city" => "Ahmedabad"
  "mobile" => "545466555"
  "facebook" => "https://facebook.com/profile/pp"
  "twitter" => "https://twitter.com"
  "youtube" => null
  "instagram" => null
  "user_id" => "132"
]

Answer 1

您需要将用户控制器中的查询更改为：

$user->profile()->create($user->toArray())->save();

您也可以看到this Example

Answer 2

您可以使用associate方法。

$user->profile()->associate($user);
