Laravel 8: Redirecting Forbidden Users To Their Respective Home Pages

Good Day

I'm new to laravel, and I'm building a website that has multiple users (Student, Supervisor, HOD). I am making use of the laratrust package to manage my users. If a student tries to access a url belonging to a supervisor, for example, laratrust throws an exception that says "USER DOES NOT HAVE ANY OF THE NECESSARY ACCESS RIGHTS". I would like to redirect the student back to their home page instead of this exception.

Here are my routes:

web.php

// Routes For Students
Route::group([
    'name' => 'student.',
    'prefix' => 'student',
    'namespace' => 'App\Http\Controllers',
    'middleware' => ['auth', 'role:student']
], function () {
    Route::get('home', 'StudentController@index')->name('student-home');
    Route::get('proposal', 'StudentController@proposal')->name('student-proposal');
    Route::get('thesis', 'StudentController@thesis')->name('student-thesis');
});

// Routes For Supervisors
Route::group([
    'name' => 'supervisor.',
    'prefix' => 'supervisor',
    'namespace' => 'App\Http\Controllers',
    'middleware' => ['auth', 'role:supervisor']
], function () {
    Route::get('home', 'supervisorController@index')->name('supervisor-home');
    Route::get('proposal', 'supervisorController@proposal')->name('supervisor-proposal');
    Route::get('thesis', 'supervisorController@thesis')->name('supervisor-thesis');
});

// Routes For HOD
Route::group([
    'name' => 'hod.',
    'prefix' => 'hod',
    'namespace' => 'App\Http\Controllers',
    'middleware' => ['auth', 'role:hod']
], function () {
    Route::get('home', 'hodController@index')->name('hod-home');
    Route::get('proposal', 'hodController@proposal')->name('hod-proposal');
    Route::get('thesis', 'hodController@thesis')->name('hod-thesis');
});

I have researched that in order to do this, I need to edit this specific part of the laratrust.php file:

    'middleware' => [

        'register' => true,

        'handling' => 'abort', // This needs to change to redirect

        'handlers' => [
            /**
             * Aborts the execution with a 403 code and allows you to provide the response text
             */
            'abort' => [
                'code' => 403,
                'message' => 'User does not have any of the necessary access rights.'
            ],

            // Redirect User To Their Respective Home Based On Their Role.
            'redirect' => [
                'url' => '/home',
                'message' => [
                    'key' => 'error',
                    'content' => ''
                ]
            ]
        ]
    ],

The home url is different based on the user type, so I want to know how I can check determine the type of user, then based on that assign their respective home url. Please let me know if you require more code or better explanation.

Return top 3 grouped results from relationship

I have a table, comments, that looks like this:

+====+=========+
| id | message |
+====+=========+
|  1 |      Hi |
|  2 |   World |
+====+=========+

I have a second table, comment_stats, which keeps track of the total number of votes on each comment, that looks like this:

+====+============+=======+
| id | comment_id | votes |
+====+============+=======+
|  1 |          1 |    10 |
|  2 |          2 |     0 |
+====+============+=======+

And lastly, I have a third table, comment_votes, which keeps track of each individual user's vote for each comment, that looks like this:

+====+============+=========+=========+
| id | comment_id | user_id |    type |
+====+============+=========+=========+
|  1 |          1 |      10 |       0 |
|  2 |          1 |       9 |       0 |
|  3 |          1 |       8 |       1 |
|  4 |          1 |       7 |       2 |
|  5 |          1 |       6 |       1 |
|  6 |          1 |       5 |       5 |
|  7 |          1 |       4 |       3 |
|  8 |          1 |       3 |       3 |
|  9 |          1 |       2 |       1 |
| 10 |          1 |       1 |       0 |
+====+============+=========+=========+

As you can see, each comment can be voted on by other users (comment_votes) and the total votes are kept track of in comment_stats. Each vote has a type. There are a total of 6 possible types (0-5).

My current Comment.php class looks like:

class Comment extends Model
{
    protected $with = [
        'votes', 'stats'
    ];

    public function votes()
    {
        return $this->hasMany('App\Vote');
    }

    public function stats()
    {
        return $this->hasOne('App\Stat');
    }
}

My Stat.php class looks like:

class Stat extends Model
{
    protected $with = [
        'topTypes'
    ];

    public function comment()
    {
        return $this->belongsTo('App\Comment');
    }

    public function topTypes()
    {
        // Need to return an array of the top 3 types here
    }
}

And my Vote.php class looks like:

class Vote extends Model
{
    public function comment()
    {
        return $this->belongsTo('App\Comment');
    }
}

I'd like to retrieve the top 3 types for each comment. So for comment_id = 1, the output would be [0, 1, 3] (as an array), in that order. 0 appears 3 times, 1 appears 3 times, and 3 appears twice. If there is a tie, it should get the lower integer type.

I'm trying to get the JSON to end up looking something like this, so that the top_types is part of stats:

{
    "id": 1,
    "message": "Hi",
    "stats": {
        "id": 1,
        "comment_id": 1,
        "votes": 10,
        "top_types": [0, 1, 3]
    }
}

How could I achieve this? All of these relationships are driving me insane.

i need pagination with sortBy in laravel

I have 3 tables products, prices, cats.

I need to filter product by cats and sort by price but I have a problem:

this code work very well but needs pagination.

$products = Product::with('photo', 'price', 'brand')
    ->whereHas('cats', function ($q) use ($cat) {
        $q->where('cat_id', $cat->id);
    })
    ->get()
    ->sortByDesc(function($query) {
        return $query->price->price;
    });

at first I did it like this:

$products = Product::with('photo', 'price', 'brand')
    ->whereHas('cats', function ($q) use ($cat) {
        $q->where('cat_id', $cat->id);
    })
    ->paginate($page)
    ->sortByDesc(function ($query) {
        return $query->price->price;
    });

but links() did not work.

After i did it like this:

$products = Product::with('photo', 'price', 'brand')
    ->whereHas('cats', function ($q) use ($cat){
        $q->where('cat_id', $cat->id);
    })
    ->paginate($page);

$products->setCollection(
    $products->sortBy(function ($query) {
        return $query->price->id;
    })
);

but sortBy does not work.

so I can't use orderBy() by join prices table

because when I do it I can show all products and I can't filter product by categories

my mind does not work, if someone can to help me, I will be very grateful

How do I convert my submitted form uploads as one pdf and send that as an attachment to receiver in laravel?

A Laravel 5.7 project

I have a form where I need to upload 3 images and 2 pdfs in single form.

What I am going for:

1. Submit the form and save data.
2. Convert the files uploaded via the user form as a single pdf.
3. Sending the converted pdf as a mail attachment using code.

Tried like this

public function sendmail(Request $request){
        $data["email"]=$request->get("email");
        $data["client_name"]=$request->get("client_name");
        $data["subject"]=$request->get("subject");

        $pdf = PDF::loadView('mails.mail', $data);

        try{
            Mail::send('mails.mail', $data, function($message)use($data,$pdf) {
            $message->to($data["email"], $data["client_name"])
            ->subject($data["subject"])
            ->attachData($pdf->output(), "invoice.pdf");
            });
        }catch(JWTException $exception){
            $this->serverstatuscode = "0";
            $this->serverstatusdes = $exception->getMessage();
        }
        if (Mail::failures()) {
             $this->statusdesc  =   "Error sending mail";
             $this->statuscode  =   "0";

        }else{

           $this->statusdesc  =   "Message sent Succesfully";
           $this->statuscode  =   "1";
        }
        return response()->json(compact('this'));
 }
