I have define user relation with portfolio but it giving me null my user model is

class User extends Model implements AuthenticatableContract,
                                    AuthorizableContract,
                                    CanResetPasswordContract
{
    use Authenticatable, Authorizable, CanResetPassword;
    protected $table = 'users';
    protected $fillable = ['name', 'email', 'password'];
    protected $hidden = ['password', 'remember_token'];

    public function portfolio()
    {
        $this->hasMany('App\Portfolio');
    }

}

My portfolio model is

class Portfolio extends Model
{

    protected $fillable = ['user_id', 'ptitle', 'pdate','pedate','purl','languages','pdes','attachments'];

    public function user()
    {
        $this->belongsTo('App\User');
    }
    public function attachments()
    {
        $this->hasMany('App\Attachment');
    }
}

and I have define foreign key on migration my migration code is

public function up()
    {
        Schema::create('portfolios', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('user_id')->unsigned();
            $table->string('ptitle');
            $table->timestamps();
            $table->foreign('user_id')
                   ->references('id')
                    ->on('users')
                    ->onDelete('cascade');
        });
    }

Answer 1

you should return the relationship to get relation data

public function portfolio()
{
   return $this->hasMany('App\Portfolio');
}

Answer 2

Basic shortend example setup (used in the following example):

class User extends Model {
    public function portfolio()
    {
        //you missed the return
        return $this->hasMany('App\Portfolio');
    }

}
class Portfolio extends Model {
    public function user()
    {
        //you missed the return
        return $this->belongsTo('App\User');
    }
}

Assuming you have an user with ID 1 and a related portfolio entry:

$mUser = User::findOrFail(1); //Return User model
$mUserLazy = User::with('portfolio')->findOrFail(1); //Preload portfolio

$mPortfolioQueryBuilder = $mUser->portfolio(); //QueryBuilder

$aPortfolio = $mUser->portfolio; //Portfolio Collection
$aPortfolio = $mUserLazy->portfolio; //Portfolio Collection
$aPortfolio = $mPortfolioQueryBuilder->get(); //Portfolio Collection
