Laravel 7 will be out 2020 with new awesome features. You can clean the way routing is been done with one line of code.

But you can try the dev version by running this code

laravel new example --dev


In laravel 7 you can bind routes like this:


Route::get('/posts/{post:slug}', function (Post $post) {
    // ...
});


Currently, Laravel 6 and below requires you to define a getRouteKeyName() method on the model like so:

<?php

class Post extends Model
{
    /**
     * Get the route key for the model.
     *
     * @return string
     */
    public function getRouteKeyName()
    {
        return 'slug';
    }
}


You can use the below route binding when you have multiple routes that you want to bind differently.

For example, the frontend route uses slugs to display posts and backend admin uses ids to manage posts:


Route::get('/posts/{post:slug}', function (Post $post) {
    // ...
});

// Or you could use the default `{post}` here...
Route::get('/admin/posts/{post:id}/edit', function (Post $post) {
    // ...
});


Thanks for reading.

In case you ran into this problem This page isn’t working www.example.com is currently unable to handle this request HTTP ERROR here is the cause and how to fix it. First, it must not be an error from your code, it is an error from querying large data from your database. So request ran out of memory, to fix it follow this step.

In your Laravel root project folder locate this file

vendor/laravel/framework/src/Illuminate/
Database/Connection.php.

Insert this line of code after line 324 

ini_set('memory_limit', '-1'); 

or follow the code snippet or image below:


 public function select($query, $bindings = [], $useReadPdo = true)    {        return $this->run($query, $bindings, function ($query, $bindings) use ($useReadPdo) {            if ($this->pretending()) {                return [];            }            // For select statements, we'll simply execute the query and return an array            // of the database result set. Each element in the array will be a single            // row from the database table, and will either be an array or objects.            ini_set('memory_limit', '-1');         

   $statement = $this->prepared($this->getPdoForSelect($useReadPdo)                              ->prepare($query));            $this->bindValues($statement, $this->prepareBindings($bindings));            $statement->execute();            return $statement->fetchAll();        });    }

How to use the same Guard name in WEB and API Using Laravel Spatie Permission

NEWS: How to use the same Guard name in WEB and API Using Laravel Spatie Permission [New  Developer] » Naijacrawl

Hi, Folks will show how to use the same guard name on your Laravel application using Laravel Spatie Permission without creating multiple guards for your web and API when building your real projects.


Spatie Permission comes with guard name it is used to authenticate user role and permission in your laravel app. But what if you have Role and Permission with Guard Name Web, it means only web can use this permission or role, when you want to use it for API to Authorize user Permission or Role, this would not work and you will always get user don't have permission to access this page.


In this article, you can now use a single Guard name for both Web and API.


Guard name depends on your application usage, guard name can be admin,user, but i prefer to use guard name as web or API, so that i don't have to create each role and permission for different guard name, and it saves time to use single guard name in all your applications. So let's start


Go to this file vendor/spatie/laravel-permission/src/Models/Role and add protected $guard_name = 'web' .

You can change the $guard_name to whatever you want to use as your guard name.

    }


}


Next go to your Model where you use HasRoles and Paste this code , eg I used HasRoles in my User Model , will use the code on my user

Copy this code


 public function hasPermissionTo($permission, $guardName = 'web'): bool {


        $permissionClass = $this->getPermissionClass();


        if (is_string($permission)) {
            $permission = $permissionClass->findByName(
                    $permission, $guardName ?? $this->getDefaultGuardName()
            );
        }


        if (is_int($permission)) {
            $permission = $permissionClass->findById(
                    $permission, $guardName ?? $this->getDefaultGuardName()
            );
        }


        return $this->hasDirectPermission($permission) || $this->hasPermissionViaRole($permission);
    }


    protected function getDefaultGuardName(): string {
        return 'web';
    }


Now all web and API can use the same guard name to check user role and permission

See complete Code on my user model


namespace App\Models\User;


use Laravel\Passport\HasApiTokens;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Database\Eloquent\SoftDeletes;
use Spatie\Permission\Traits\HasRoles;


class User extends Authenticatable implements MustVerifyEmail {


    use HasApiTokens,
        SoftDeletes,
        HasRoles,
       ;


    public function hasPermissionTo($permission, $guardName = 'web'): bool {


        $permissionClass = $this->getPermissionClass();


        if (is_string($permission)) {
            $permission = $permissionClass->findByName(
                    $permission, $guardName ?? $this->getDefaultGuardName()
            );
        }


        if (is_int($permission)) {
            $permission = $permissionClass->findById(
                    $permission, $guardName ?? $this->getDefaultGuardName()
            );
        }


        return $this->hasDirectPermission($permission) || $this->hasPermissionViaRole($permission);
    }


    protected function getDefaultGuardName(): string {
        return 'web';
    }


    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'id', 'slug', 'username', 'email', 'email_verified_at', 'created_at', 'password',
    ];


    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];


    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
  

    protected $casts = [
        'email_verified_at' => 'datetime',
    ];



}
