use Illuminate\Foundation\Auth\User as Authenticatable;
use Zizaco\Entrust\Traits\EntrustUserTrait;
use Session;
use Illuminate\Support\Facades\DB;

{
use Notifiable;
use EntrustUserTrait;
protected $table = 'tbl_users';
protected $primaryKey = 'id';
protected $guarded = ['id'];
const API = 'api';
const WEB = 'web';
/**

*
* #var array
*/
protected $fillable = [
'name', 'email', 'password', 'last_login', 'Address', 'Age', 'DateOfBirth', 'created_by', 'deleted_by'

/**

use DB;
use App\Models\CarePlanData;
use Session;
class Company extends Model
{
protected $table = 'companies';

static public function fetchAllActiveCompanies()
{
return DB::table("companies")->where(['is_active' => 1])->pluck('name', 'id');
}
// change company to hasmany
public function users()
{
return $this->hasmany('App\Models\User');
}
}
and this is how i am trying to access the Company , but i am getting null.
public function fetchCompany(){
$User = User::find($user->id);
dd($User->company());
}

Answer 1

First of all if a user belongs to 1 company then it should be:
public function company()
{
$this->belongsTo("App\Models\Company", "company_id");
}
then fetchCompany() should be
public function fetchCompany(){
$User = User::with('company')->find($user->id);
dd($User->company);
}
You need to use with to load the relations. You pass the name of the function which defines the relation in your User model to with like this with('function_name').

Answer 2

Your actual question is:
You have belongTo Relation between User and Company but when you trying to access the Company via user object, you get null
In your User.php Model put the following function but if you already have then leave it:
public function company()
{
$this->belongsTo("App\Models\Company", "company_id");
}
Then
Replace this function:
public function fetchCompany(){
$User = User::find($user->id);
dd($User->company());
}
To is one:
public function fetchCompany(){
$User = User::find($user->id);
if($User){
dd($User->company()->get());
}
}
or to this one:
public function fetchCompany(){
$User = User::find($user->id);
if($User){
dd($User->company);
}
}

Answer 3

actually if your company_id field is on user model, then your relation should be
public function company()
{
$this->belongsTo("App\Models\Company", "company_id");
}
unless a user can have many companies ?
