我正在做一个项目，我被分配了一项任务来为应用程序创建用户管理。但我一直坚持表关系及其迁移。
努力
我有这些表：
- 用户
- 用户身份
- 用户名
- 密码
- 简介
- profile_id
- 用户身份
- 名
- 姓
- 电子邮件
地址
- address_id
- profile_id
- 地址
- 城市
- 状态
- 国家
- PIN码
- 配置
- config_id
- 配置名称
- 配置类型
- parent_id
现在我必须为上述相同的结构创建模型和迁移。为此，我在模型和迁移类下创建/修改。
型号：用户
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'username', 'password',
];
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function profile()
{
return $this->hasOne('Profile','user_id');
}
}
迁移：2014_10_12_000000_create_users_table.php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
/**

*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('user_id');
$table->string('username');
$table->string('password', 60);
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('users');
}
}
型号：型材
use Illuminate\Database\Eloquent\Model;
class Profile extends Model
{
public function user(){
return $this->belongsTo('User');
}
public function address()
{
return $this->hasOne('Address','address_id');
}
}
迁移：2016_02_26_101749_create_profiles_table.php
use Illuminate\Database\Schema\Blueprint;

$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('user_id')->on('users')->onDelete('cascade');
$table->string('lastname')->nullable();
$table->string('firstname')->nullable();
$table->string('gender')->nullable();
$table->string('email')->unique();
$table->string('phonenumber', 20)->nullable();
$table->timestamps();
});
}
/**

public function down()
{
Schema::drop('profiles');
}
}
型号：地址
namespace App;

public function profile(){
return $this->belongsTo('Profile');

public function country() {
return $this->hasOne('Configuration', 'config_id');

}
迁移：2016_02_26_102805_create_addresses_table.php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateAddressesTable extends Migration
{
/**

public function up()

}
/**

public function down()

Schema::drop('addresses');
}
}
型号：配置
namespace App;
use Illuminate\Database\Eloquent\Model;
class Configuration extends Model

public function children() {
return $this->hasMany('Configuration','parent_id');
}
public function parent() {
return $this->belongsTo('Configuration','parent_id');
}
public function address(){
return $this->belongsTo('Address');
}
}
迁移：2016_02_26_104519_create_configurations_table.php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateConfigurationsTable extends Migration
{
/**

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();
});
}
/**

*
* @return void
*/
public function down()
{
Schema::drop('configurations');
}
}
现在，当我运行php artisan migrate时，我收到错误消息：
.
请建议我如何做到这一点。我必须使用相同的表结构并且不能修改它。如果需要任何进一步的更新或我忘记了什么，请告诉我。
