我正在嘗試使用另一個(gè)表（個(gè)人資料）擴(kuò)展用戶模型以獲取個(gè)人資料圖片、位置等。
我可以重寫(xiě)使用者模型的 index() 函數(shù)來(lái)做到這一點(diǎn)嗎？
目前型號(hào)代碼：
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;
protected $fillable = [
'name',
'email',
'password',
'user_group'
];
protected $hidden = [
'password',
'remember_token',
];
protected $casts = [
'email_verified_at' => 'datetime',
];
}

您想要做的是在User 模型和新的Profile 模型之間建立關(guān)係。為此，您首先需要建立一個(gè)模型 Profile 及其關(guān)聯(lián)的 Tabble profiles
php artisan make:model Profile --migration
在database\migrations中應(yīng)該有一個(gè)名為2022_11_28_223831_create_profiles_table.php
現(xiàn)在您需要新增一個(gè)外鍵來(lái)指示此設(shè)定檔屬於哪個(gè)使用者。
public function up()
{
Schema::create('profiles', function (Blueprint $table) {
$table->id();
// $table->string('path_to_picture')
// user id
$table->foreignId('user_id')->constrained()->onDelete('cascade');
$table->timestamps();
});
}
現(xiàn)在在您的使用者模型中加入以下函數(shù)
public function profile()
{
return $this->hasOne(Profile::class);
}
在您的個(gè)人資料模型中
public function user()
{
return $this->belongsTo(User::class);
}
運(yùn)行php artisan migrate，一切都應(yīng)該按預(yù)期工作
如果您想測(cè)試關(guān)係是否如預(yù)期運(yùn)作，請(qǐng)建立一個(gè)新的測(cè)試案例
php artisan make:test ProfileUserRelationTest
#在tests\Feature\ProfileUserRelationTest.php
<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
use App\Models\User;
use App\Models\Profile;
use Illuminate\Support\Facades\Hash;
class ProfileUserRelationTest extends TestCase
{
use RefreshDatabase;
public function test_the_relation_between_user_and_profile_works()
{
$user = User::create([
'name' => 'John Doe',
'email' => 'jd@example.com',
'password' => Hash::make('password'),
]);
$profile = new Profile();
$profile->user_id = $user->id;
$profile->save();
$this->assertEquals($user->id, $profile->user->id);
$this->assertEquals($user->name, $profile->user->name);
$this->assertEquals($profile->id, $user->profile->id);
}
}
現(xiàn)在您可以執(zhí)行 php artisan test 來(lái)查看是否一切正常。
小心這會(huì)刷新您的資料庫(kù)！ 所以不要在生產(chǎn)中進(jìn)行測(cè)試。
輸出應(yīng)該是這樣的
PASS Tests\Unit\ExampleTest ? that true is true PASS Tests\Feature\ExampleTest ? the application returns a successful response PASS Tests\Feature\ProfileUserRelationTest ? the relation between user and profile works Tests: 3 passed Time: 0.35s

替代方案
$user = User::create([
'name' => 'John Doe',
'email' => 'jd@example.com',
'password' => Hash::make('password'),
]);
$user->profile()->create(...); // replace the ... with the things you want to insert you dont need to add the user_id since it will automatically added it. It will still work like the one above.
