Hey guys. I have website that have frontend based on API and server side admin panel (voyager). Currently it uses different auth drivers: jwt (https://github.com/tymondesigns/jwt-auth) for api, session for web. I want to automatically log in to the admin panel when logging in via jwt. Is it possible?

p.s. if i set jwt driver for "web" it throws "Auth driver [jwt] for guard [web] is not defined.". p.s. 2, I can't access to session from other drivers. For example I can't create middleware with

$user = auth()->guard('api')->user()

and attach it to web. It will return null and I don't know why.

Hello.

I store attachments directly in database (column with raw binary code).

So when I do $attachment = Attachment::take(20)->get() it loads all data in variables (with binary code included).

File may have big size and it will put hundreds of megabytes in RAM.

Is there any way to exclude some columns from DB and load it by lazy way, like relations?

For example:

$attachment = Attachment::find(123);
// $attachment->content === null
$attachment->content; // <<BINARY CODE>> (loaded from database)

Exactly, thanks!

I want to work with collections even if data is single model:

So if I do collect($collectionOfModels) its do nothing = GOOD.

If I do collect($singleModel) its wraps all model's properties (instead of model) like this:

array:2 [
  "id" => 1
  "name" => "Alex"
]

But I want this:

array:1 [
  array:2 ["id" => 1, "name" => "Alex"],
]

So every time I do that trick:

$collectionOrSingleModel = getData();

if ($collectionOrSingleModel instanceof Model) {
    $collectionOrSingleModel  = collect([collectionOrSingleModel ]);
}

foreach ($collectionOrSingleModel as $singleModel) {
    // ...
}

It works fine but I don't feel good. Is there any better way to do that?

I probably found the solution (in model code):

    protected $touchedProperties = [];

    /**
     * @param $key
     * @param $value
     */
    public function setAttribute($key, $value)
    {
        $this->touchedProperties[$key] = $value;

        parent::setAttribute($key, $value);
    }

I know about getDirty() method, that gives me properties that been changed (before save()). But what if I want to know properties that haven't changed at all (but It was setted)?

For example:

$user = User::where('name', 'Alex')->first(); // ID: 123, NAME: 'Alex', CITY: 'New York' etc...
$user->name = $user->name; 

So I want detect that there was try to change 'name' column. Is there any easy way to do that?

Probably yes.

I have collection with these properties:

id | name | parent_id

1  | Category2 | null
2  | Element1   | 2
3  | Element3   | 1
4  | Category1 | null
5  | Element4   | 2
6  | Element1   | 1

I want to sort parent categories then its childs.

So in case above I want to receive that result:

id | name | parent_id

1  | Category1 | null
3  | Element3   | 1
6  | Element1   | 1
4  | Category2 | null
5  | Element4   | 2
2  | Element1   | 2

Is there any way to do that by using sort or sortBy methods?

I log all my model updatings in database by using this in updating event of my models:

$originalData = $this->changeable->getOriginal();
$dirtyData = $this->changeable->getDirty();

// save changes of properties in some table...

So, its works fine, but it gives my only ID of changing properties.

For example status_id was changed, and it will put this in db:

key            | old_value  | new value
-------------------------------------------------
status_id  | 3                 |  4

But I want to store name property of status via relation:

key            | old_value                     | new value
------------------------------------------------------------------
status_id  | In progress                 |  Completed

Is there any way to do that?

So I have custom request class that handle my html form.

In request class I have validation rule like: ['users' => 'sometimes|exists:users,id'].

And in my controller I have:

$users = User::find($customRequest->get('users'));

So in this case I think I have double query for validating (but it's not critical I guess) and user search and I want to get rid of finding users in my controller.

So in my controller I want like this:

function test(CustomRequest $request) 
{
    $users = $request->get('users'); // array or collection of models (not ids!!)
}

Is there any difference?

I have the file that exists in my storage folder.

Is it possible to validate his parameters via laravel validator?

I mean not while uploading it in request.

For some reason I store validation in database in string column, for example:

id  |  field | rules
-------------------
1  |  first_name | required|bail|max:50
2  |  last_name | required|bail|max:70

So when I validate through Laravel validator I load these rules from DB.

But now I need to validate some filelds with custom Rules.

In code I can do that: 'field' => ['required', 'bail', new CustomRule].

But I store my rules in DB in varchar column so I cant create Rule instance.

Is it possible to validate through custom Rule class from string rules?

Something like this: 'field' => 'required|bail|max:70|class:App\Rules\CustomRule'

It will need to search post manually in controller method. Is is possible to "inject" finded model like public function show(Post $post)?

I have this route:

Route::get('/posts/{post:slug}-{post:id}', '[email protected]');

But it throws an exception Route pattern "/posts/{post}-{post}" cannot reference variable name "post" more than once..

Is is there an any way to make this work? I mean to make Laravel magic to search the model by two keys:

public function show(Request $request, Post $post) 
{
    // $post = Post::where(['id' => ..., 'slug' => ...])->firstOrFail()
}

For example I have model Car that has many Wheels.

Is it possible to save that model like this way or similiar?:

$car = new Car();

$car->wheels = collect([
    new Wheel(['name'] => 'wheel 1'), 
    new Wheel(['name'] => 'wheel 2'), 
    new Wheel(['name'] => 'wheel 3'), 
    new Wheel(['name'] => 'wheel 4'), 
]);

SomeFilter::filter($car);

$car->save();

I need that because I want to create model with relations (which has not yet been saved in the database) and pass this object through the filter (other class/method) and save in database the "filtered" result.

$entityName may have different classes, not only class A.

I have class A and class B.

I want the property with the class "A" name to be automatically set when creating an instance of class "B".

For example:

<?php 

namespace App;

class B {
    public $entityName;

    public function __construct($entityName)
    {
         $this->entityName = $entityName;
    }
}

<?php 

namespace App;

class A {
    public function test() 
    {
        $b = app(\App\B::class);
        echo $b->entityName; // SHOULD RETURN STRING "\App\A"
    }
}

Is it possible to make that without doing it manually app(\App\B::class, ['entityName' => static::class])?

TY. why u use $journey->current_point instead of $journey->currentPoint

For examle I have 2 models:

• Journey (has points)
• Point (belongs to journey)

Journey model has 2 methods:

public function points()
{
    return $this->hasMany(Point::class);
}

public function currentPoint()
{
    return $this->hasOne(Point::class);
}

I want to make currentPoint return single point that have status = 0 (not visited, for example) and lowest position (of all points of this journey). So if Journey can have multiple points, only one currentPoint can be.

I want relation, not just query builder object.

Is it possible to do that?

I have two models:

1. Man implements Walkable
2. Woman implements Walkable

Also I have two routes:

1. /man/{man}
2. /woman/{woman}

In both controllers I have same method: the difference only in arguments:

1. testMethod(Man $man)
2. testMethod(Woman $woman)

All I want is to create a trait with method like this and use it in both controllers: testMethod(Walkable $walkable)

But laravel does not inject model. Is it possible to do that I want?

I have 3 models Document, Status, ApprovalAttempt.

documents
    id - integer
    name - string

statuses
    id - integer
    approval_attempt_id - integer (foreign key)

approval_attempts
    id - integer
    approvable_type - string (polymorphic model name)
    approvable_id - integer (polymorphic model id)

How can I access from Document model to its statuses?

I thought I can do like this, but I cant:

public function statuses()
{
    return $this->approvalAttempts()->statuses();
}
