How to create table migration in Laravel 5

I am working on a project where, i have been assigned a task to create user management for the application. But i have stuck on the table relationship and their migration.

Effort

I have these tables:

1. Users
   • user_id
   • username
   • password
2. Profiles
   • profile_id
   • user_id
   • firstname
   • lastname
   • email

3. Address

   • address_id
   • profile_id
   • address
   • city
   • state
   • country
   • pincode
4. Configurations
   • config_id
   • configuration_name
   • configuration_type
   • parent_id

Now I have to create model and migration for the same above structure. For this i have create/modify below model and migration class.

Model: User

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');
    }
}

Migration: 2014_10_12_000000_create_users_table.php

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('user_id');
            $table->string('username');
            $table->string('password', 60);
            $table->rememberToken();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('users');
    }
}

Model: Profile

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');
    }
}

Migration: 2016_02_26_101749_create_profiles_table.php

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('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();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('profiles');
    }
}

Model: Addess

namespace App;

use Illuminate\Database\Eloquent\Model;

class Address extends Model
{
    public function profile(){
        return $this->belongsTo('Profile');
    }

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

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

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

Migration: 2016_02_26_102805_create_addresses_table.php

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');
    }
}

Model: Configuration

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');
    }
}

Migration: 2016_02_26_104519_create_configurations_table.php

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');
    }
}
