【问题描述】：
我遇到了大问题，我在我的项目中维护雄辩的关系设置，我有以下关系：
- 与登录相关的用户信息存储在 users 表中。
- 存储在配置文件信息中的用户配置文件相关信息。
- 用户地址存储在地址表中
- 存储在城市、州、国家等配置中的配置相关信息
努力
这是迁移和模型及其关系：
用户迁移表：
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('email')->unique();
$table->string('password', 60);
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('users');
}
}
用户模型：
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'email', 'password',
];
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function profile()
{
return $this->hasOne('App\Profile','user_id');
}
}
配置文件迁移表：
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateProfilesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('profiles', function (Blueprint $table) {
$table->increments('profile_id');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
$table->string('lastname')->nullable();
$table->string('firstname')->nullable();
$table->string('gender')->nullable();
$table->string('phonenumber', 20)->nullable();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('profiles');
}
}
个人资料模型：
namespace App;
use Illuminate\Database\Eloquent\Model;
class Profile extends Model
{
protected $fillable = [
'firstname', 'lastname',
];
public function user(){
return $this->belongsTo('App\User');
}
public function address()
{
return $this->hasOne('App\Address','profile_id');
}
}
配置迁移表：
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateConfigurationsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('configurations', function (Blueprint $table) {
$table->increments('config_id');
$table->string('configuration_name');
$table->string('configuration_type');
$table->string('parent_id');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('configurations');
}
}
配置模型：
namespace App;
use Illuminate\Database\Eloquent\Model;
class Configuration extends Model
{
public function children() {
return $this->hasMany('App\Configuration','parent_id');
}
public function parent() {
return $this->belongsTo('App\Configuration','parent_id');
}
public function city() {
return $this->hasOne('App\Address', 'city');
}
public function state() {
return $this->hasOne('App\Address', 'state');
}
public function country() {
return $this->hasOne('App\Address', 'country');
}
}
地址迁移表：
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateAddressesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('addresses', function (Blueprint $table) {
$table->increments('address_id');
$table->integer('profile_id')->unsigned();
$table->foreign('profile_id')->references('profile_id')->on('profiles')->onDelete('cascade');
$table->string('address')->nullable();
$table->integer('city')->unsigned();
$table->foreign('city')->references('config_id')->on('configurations')->onDelete('cascade');
$table->string('pincode')->nullable();
$table->integer('state')->unsigned();
$table->foreign('state')->references('config_id')->on('configurations')->onDelete('cascade');
$table->integer('country')->unsigned();
$table->foreign('country')->references('config_id')->on('configurations')->onDelete('cascade');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('addresses');
}
}
地址模型：
namespace App;
use Illuminate\Database\Eloquent\Model;
class Address extends Model
{
public function profile(){
return $this->belongsTo('App\Profile');
}
public function city() {
return $this->belongsTo('App\Configuration');
}
public function state() {
return $this->belongsTo('App\Configuration');
}
public function country() {
return $this->belongsTo('App\Configuration');
}
}
我使用Eloquent relation setup, two foreign keys to same table 建立我的项目关系。但不幸的是，上面的代码不会产生期望的输出。看看：
如果我使用命令Auth::user()->profile->firstname，它将打印用户名。因此，如果我使用 Auth::user()->profile->address->city 它应该打印存储在配置表中的城市名称，而是打印名称它打印 id。
请给我建议解决方案。
谢谢，
