Truncate a table in Laravel 5

Question

Description : I have a table full of tested data. Sometimes, I want to clear it out for new data. I can perform the truncate in the DBMS App like MySQL WorkBench, but I'm trying to achieve it within my application instead.

---

Goal : to make a button to truncate a table in a database when on click.

---

Here are my steps :

1 - Declare a route

Route::delete('visitor/truncate',array('as'=>'visitor.truncate', 'uses'=>'VisitorController@truncate')); 

---

2 - Create a truncate function in my VisitorController

public function truncate() {      $visitors = Visitor::all();     $visitors ->truncate();      return View::make('visitors.index')         ->with('success', 'Truncate Done'); } 

---

3 - Create a button on my view

 {!! Form::model($visitors, array( 'route' => array('visitor.truncate'),'method' => 'DELETE')) !!}           <button type="submit"  class="btn bgm-red btn-float waves-effect waves-effect waves-button waves-float"><i class="md md-remove"></i></button>       {!! Form::close()!!} 

---

4 - Test

When I click on it, it get into my truncate() function in my controller, but I keep getting this error

Call to undefined method Illuminate\Database\Eloquent\Collection::truncate()

---

Do I need include anything to use truncate() ?

Any hints on that will be much appreciated !

Answer 1

the following should work as well,

Visitor::truncate();

Answer 2

The truncate method is part of the Query Builder. However Visitor::all() returns a Collection instance. You need to build the query using the following:

Visitor::query()->truncate();
