使用Laravel 5.2。Laravel - 爲不同用戶重複輸入具有獨特參數
我正在Laravel開發一個電話簿項目，在那裏您將聯繫信息存儲在名爲Contacts的表中。 爲了在這個表中創建新的聯繫人，您已註冊，並且您的信息將被記錄在一個users表
我創建的視圖來顯示Contacts表，並在控制器我想出了一個邏輯，只顯示您在表格中創建的聯繫人。所以，這意味着你無法看到表中另一個用戶創建的聯繫人。
這種邏輯是爲了防止用戶失去其聯繫人的蹤跡。例如，作爲一個用戶，我只創建了2個聯繫人，但是如果我的表有超過500個條目，我將不得不在表格中深入查找我的聯繫人。
但是聯繫人，特別是email和phone條目必須是唯一的，所以我們在表中沒有重複的信息。 這就產生了一個問題，因爲我看不到其他用戶在此表中創建的聯繫信息。因此，讓我們說，我和我的兄弟想要存儲我妹妹的聯繫人，只有我們其中一人能夠創建此信息，只有創建它的人才能看到此信息。
這裏是我的問題
如何「授權」相同的接觸，以示對未不失unique參數創建它的用戶？
下面是一些我的代碼（包括一些澄清）：
用戶遷移
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class PhonebookUsers extends Migration
{
protected $primaryKey = 'name';
public $incrementing = false;
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->integer('id')->unsigned()->autoIncrement();
$table->string('user_image');
$table->string('name');
$table->string('email', 191)->unique();
$table->string('password', 191);
$table->timestamp('updated_at');
$table->timestamp('created_at');
$table->rememberToken();
});
}
用戶驗證參數
...
public function rules()
{
return [
'user_image' => 'file',
'name' => 'required|alpha|min:3|max:255',
'email' => 'required|unique:users,email|email',
'password' => 'required|alpha_num|between:6,100',
];
}
...
聯繫人遷移
...
public function up()
{
Schema::create('contacts', function (Blueprint $table) {
$table->integer('id')->unsigned()->autoIncrement();
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->string('image');
$table->string('name');
$table->string('lastname');
$table->string('email', 191);
$table->string('phone',191);
$table->string('address');
$table->string('description', 255);
});
}
...
注意遷移包括列，user_id，識別，通過ID，誰創造了一個接觸用戶。
聯繫人驗證參數
...
public function rules()
{
return [
'image' => 'file',
'name' => 'alpha|min:3|max:15|required',
'lastname' => 'alpha|min:3|max:15',
'email' => 'required|email|unique:contacts,email',
'phone' => 'required|alpha_num|between:3,25|unique:contacts,phone',
'address' => 'max:255',
'description' => 'max:255'
];
}

ContactsController

}

$fileName = str_random(10);
// take this name we just created add the file's extension using the original extension
//adiciona extensão da imagem no nome do arquivo
$fileName .= '.' . $request->file('image')->getClientOriginalExtension();

// Salva a imagem no diretorio selecionado

$contact->save();

在此先感謝。
如果你有這樣的要求，那麼你必須做手工的方法來檢查這些規則 –
