Laravel Relation returning null result - laravel-5

Question

My Laravel relation is returning a null result. Can anyone help what i am doing wrong.
Model code is :
public function title()
{
$branch_id=session()->get('lbranch','0');
return $this->hasOne('App\Accounts','code','supp_code')
->select('title')->where('branchid','=',$branch_id);
}
and Controller code is :
$data = Purchase::with('title')
->where('purchases.branchid',$branch_id)
->select('purchases.*',
DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'))
->latest()->get();
the queries generated are :
select `purchases`.*, (CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status from `purchases`
where `purchases`.`branchid` = 22 order by `created_at` desc
select `title` from `accounts` where `branchid` = 22 and `accounts`.`code` in (100)
UPDATE :
If I use join, the following query is working fine :
$data = DB::table('purchases')
->where('purchases.branchid',$branch_id)
->where('accounts.branchid',$branch_id)
->leftjoin('accounts','purchases.supp_code','=','accounts.code')
->select('purchases.*',
DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'),
'accounts.title')
->latest()->get();

Answer 1

It seems you have issue in your relationship definition. Please do confirm the Model name for the account. It should be Account instead of Accounts. But still you should confirm in your application.
public function title()
{
---
return $this->hasOne('App\Accounts','code','supp_code')
---;
}
Should be
public function title()
{
---
return $this->hasOne('App\Account','code','supp_code')
---;
}
However I try to run your code and it working fine for me.
Here is what I have tried.
App\Models\Purchase.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Purchase extends Model
{
/**
* get model table name.
*
* #var string
*/
public $table = "purchases";
public function title()
{
$branch_id=22;
return $this->hasOne('App\Models\Account','code','supp_code')
->select('title')->where('branchid','=',$branch_id);
}
}
App\Models\Account.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Account extends Model
{
/**
* get model table name.
*
* #var string
*/
public $table = "accounts";
}
in route file.
<?php
Route::get('/', function(){
$branch_id = 22;
$data = Purchase::with('title')
->where('purchases.branchid',$branch_id)
->select('purchases.*',
\DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'))
->latest()->get();
dd($data->toArray());
$data = \DB::table('purchases')
->where('purchases.branchid',$branch_id)
->where('accounts.branchid',$branch_id)
->leftjoin('accounts','purchases.supp_code','=','accounts.code')
->select('purchases.*',
\DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'),
'accounts.title')
->latest()->get();
dd($data);
});
Both query working for me. And returning the desire result.

Edits:
Tryied running your code.. here is the changes suggested.
PurchaseController
public function index()
{
//
$branch_id = 22;
$data = Purchase::with('account')
->where('purchases.branchid',$branch_id)
->select('purchases.*',
\DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'))
->latest()->get();
dd($data->toArray());
/*$data = \DB::table('purchases')
->where('purchases.branchid',$branch_id)
->where('accounts.branchid',$branch_id)
->leftjoin('accounts','purchases.supp_code','=','accounts.code')
->select('purchases.*',
\DB::raw('(CASE
WHEN purchases.posted = "1" THEN "Posted"
ELSE "Unposted"
END) AS status'),
'accounts.title')
->latest()->get();
dd($data);*/
}
Purchage Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Purchase extends Model
{
//
public $table = "purchases";
public function account()
{
$branch_id=22;
return $this->hasOne('App\Account','code','supp_code')
->where('branchid', $branch_id);
