Display unit count in Laravel blade template - php

Question

I want to show total count of the unit so I wrote {{ ($unit->unit_id)->count() }} to return the data.
blade.php
<tbody>
#foreach($developer as $key => $data)
<tr>
<td></td>
<td>{{$data->developer_name}}</td>
<td>
#foreach($data->projects as $key => $project)
{{ $project->project_name }}<br>
#endforeach
</td>
<td>
#foreach($data->projects as $key => $project)
#foreach($project->phase as $key => $phase)
#foreach($phase->unit as $key => $unit)
{{ ($unit->unit_id)->count() }}<br> //error
#endforeach
#endforeach
#endforeach
</td>
</tr>
#endforeach
</tbody>
UPDATE:
Unit.php Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Unit extends Model
{
//
protected $table="pams_unit";
protected $primaryKey="unit_id";
}
UnitController
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use App\Unit;
use App\Developer;
class UnitByDeveloperController extends Controller
{
//
public function __construct()
{
$this->middleware('auth');
}
public function show(Request $request){
$dev_id = $request->input('dev_id');
$developer =Developer::where(function($query1) use($dev_id){
if($dev_id){
$query1
->where('id',$dev_id);
}
})
->active()
->paginate('8');
return view('reportlayout.unitByDeveloper',compact('developer'));
}
}
But, an error is showing :-
Call to a member function count() on integer
Anyone can help me to spot my mistake ?

Change this:
{{ ($unit->unit_id)->count() }}
To:
{{ $unit->count() }}
