What is it about ?

I am using Laravel 5.2 and update the composer by running the following command

composer require felixkiss/uniquewith-validator:2.*

and then added the following to your providers array in config/app.php:

'providers' => array(
    // ...

    'Felixkiss\UniqueWithValidator\UniqueWithValidatorServiceProvider',
),

I did this because I am trying to implement Multiple column Unique Validation. I mean Composite Key Validation.

I am following the instructions as mentioned here

What's the issue ?

When Laravel runs the below line.

public function store(Request $request)
{
    $v = \Validator::make($request->all(), [
        'SubCategory' => 'required|max:25|min:5|unique_with:tblsubcategory,CategoryID',
        'CategoryID' => 'required',
    ]);

    if ($v->fails()) {
        return \Redirect::back()
                    ->withErrors($v)
                    ->withInput();
    }
    return Redirect('/SubCategories-List/'.$request->input('CategoryID'));
}

I get this error.
