laravel user only vote once in a form

Question

I have a question about an user vote system that I want to make.

Is it possible to make kind of role model in the users model, and that if the user has voted (it is a form that they fill in) they cannot view that page or cannot submit the form again because they already voted once.

But I am not sure if this is possible, do you know if there is a way to make this possible?

Update

Users Model:

protected $table = 'users';

protected $fillable = ['email', 'password', 'voted'];

protected $hidden = ['password', 'remember_token'];

Option Model:

protected $table = 'options';

protected $fillable = ['id, points'];

User migration

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('email')->unique();
        $table->string('password');
        $table->boolean('voted')->default(0);
        $table->rememberToken();
        $table->timestamps();
    });
}

Option Migration

public function up()
{
    Schema::create('options', function(Blueprint $table)
    {
        $table->increments('id');
        $table->string('option');
        $table->tinyInteger('points');
        $table->timestamps();
    });
}

Maybe good to know, in my RoundOneController@update I have 2 If else statements. (If select box 1 is id from database, then update, else make new one. Same for select box 2) But if there is a possibility that when this has ended the users table will be updated and the voted column will change to 1, than the user cannot vote anymore.

Without seeing how your code is setup, there are in fact several ways to accomplish this.

One way would be to have a voted column in your User Model. If you set it up as a boolean in your Migrations with a default value of 0,

Schema::table('users', function ($table) {
    $table->boolean('voted')->default(0);
});

then you can just set it to '1' after a User votes. Then set up Middleware for the voting page which checks for the presence of this value.

middleware file:

public function handle($request, Closure $next)
{
     if (Auth::user()->voted) {
         return redirect('home');
     }

     return $next($request);
}

Make sure to register the Middleware in kernal.php

protected $routeMiddleware = [
    ......
    'voted' => \App\Http\Middleware\RedirectIfVoted::class,
];

and apply it to your route(s):

Route::get('user/vote', ['middleware' => ['voted'], function () {
    //
}]);
