Description
A small addition to the resources to the Laravel,
which is a dumb modifiable due to the overridency of
the main team of the Laravel to the new Stub in which
another resource inheritance is included which, in turn,
everything is also inherited from
Illuminate\Http\Resources\Json\JsonResource so that
the reasons of the Laravel will understand it as a
full-fledged resource.
About the concept.
The concept of expansion is to reduce resources and make
them more flexible and versatile. The flexibility lies
in the fact that each field is to have an independent
additional possibility of obtaining data on paths and
the use of the Laravel Eloquent Casts and Laravel Eloquent Mutators.
Also knows how to determine the relationship of models and connect the fields when
they are loaded. Rule for pagination.
Possibilities
The possibilities of this package in aggregate with the bfg/route pack allow me to
organize a not big but very powerful pattern for api that can compete with
convenience with the GraphQL.
Where can I use it?
This package is intended only in order to make an add-in over the framework Laravel. With the full use of the package, it is rapidly back and efficiently implement a resistant API resource for models and not only.
Create new resource
In order to create a resource, it is enough to use the standard Command:
php artisan make:resource user
I added some properties there:
-m, --model[=MODEL] Create with the model
-r, --route Create with route
-c, --collection Create a resource collection
After execution, the app/Http/Resources/UserResource.php file will
be created with the following contents:
<?php namespace App\Http\Resources; use App\Models\User; use Bfg\Resource\BfgResource; use Bfg\Resource\Traits\ModelScopesTrait; use Bfg\Resource\Traits\EloquentScopesTrait; /** * @mixin User */ class UserResource extends BfgResource { use EloquentScopesTrait, ModelScopesTrait; /** * Map of resource fields * @var array */ protected array $map = [ ]; }
Further, all we need is to fill out a resource map.
... protected array $map = [ 'id', 'name', 'email', 'phone', 'photo', // Variants 'avatar' => AvatarResource::class, // Use resource 'avatar' => [AvatarResource::class, 'photo'], // Path to field 'avatar' => [AvatarResource::class, 'photo.src'], // You can use a dot path, for relations an example 'avatar' => ['photo.src'], // Or just set a new path for field in array 'avatar' => 'photo.src', // Or in string ]; ...
Mutators
For example, in the case of the user, for its photo we need to
process the data for this field and for it we can use the mutator for it.
All mutators are determined by the same rules as in the Laravel models only
instead of Attribute write Field.
... public function getPhotoField ($value) { return $value ? asset($value) : asset('images/default_photo.jpg'); } ...
Casting
All resource casting rules are completely copied from the
casting of Laravel Attributes
and their functionality is absolutely identical (except for the set of custom casts):
... protected array $casts = [ 'id' => 'int' ]; ...
Extending (Re-use)
Combines the results of resource fields. Performed before the main resource for redefining the parent.
Important! Common resources should work with one model.
... protected array $extends = [ UserResource::class => ['id', 'name'], // Insert only id and name fields UserDetailsResource::class => 'phone', // Insert only phone field UserCommentResource::class, // Inserted all fields ]; ...
Routing
To use resources as API Controllers, I recommend that you use Laravel Fortify or JetStream as an API provider.
Definition of routs
In your RouteServiceProvider Add the pointer to search for routs:
... /** * Define your route model bindings, pattern filters, etc. * * @return void */ public function boot() { $this->configureRateLimiting(); $this->routes(function () { ... Route::find( __DIR__.'/../Resources', Route::prefix('api') ->middleware(['api', 'auth:sanctum']) ->as('api.') ); //Route::prefix('api') // ->middleware('api') // ->namespace($this->namespace) // ->group(base_path('routes/api.php')); ... }); } ...
Then you need to add an attribute to the resource class:
... use Bfg\Resource\Attributes\GetResource; /** * @mixin User */ #[GetResource] class UserResource extends BfgResource { ... }
After that, you will appear in the route link api/user/{scope}
that refers to this resource.
Scopes in routes
All resource skys should be static and public.
By linking the parameters of scopes must be understood as they work.
The idea of a sequential call of scopes is as follows:
The sequence of them is fixed sequentially through the slash in the query reference,
for example:
[GET] http://example.com/api/user/get/only/...
In the result you will receive a list of users without any fields as Only
accepts the parameters, namely the fields that need to be displayed. In order
to transfer the fields in scope, we use the same syntax as the sequential call
only after each scope goes its parameters, the resource controller processes
the string sequentially and if scope is found in this sequence, it needs to be
performed. All other parameters after it are considered to be the parameters of
the scope if the name of the other (next) scope does not occur in these names
and so to the end.
This is how the request for obtaining data with pagination and field filtering is:
Important! Your resource must be connected to the trait
Bfg\Resource\Traits\EloquentScopesTraitandBfg\Resource\Traits\ModelScopesTrait
[GET] http://example.com/api/user/paginate/15/only/id/name [GET] http://example.com/api/user/[:paginate]/[perPage]/[:only]/[field]/[field]
Each of each scope is single for each pre request, on thescope
After pagination, the collection also returns, and in this case,
each of its recording is processed only scope.
Fields that have not entered the resource after scope only Fill the null
Put a question mark ? In front of the field name in the resource map:
... protected array $map = [ '?id', // <-- ]; ...
Fill in the resource an array with fields that must be temporary:
... protected array $temporal = [ 'id', // <-- ]; ...
Put the trigger to true, which will make temporary all resource fields:
... protected bool $temporal_all = true; ...
Scopes in resource
In the class of the Scopes resource look like public static functions with the
name in CamelCase and postfix Scope
Consider what the standard Resource Eloquent Get Scope:
... public static function getScope($model): mixed { return $model->get(); } ...
The first parameter in Scope goes the current model that came either from the
previous scope either the standard resource model that will try to determine
automatically depending on the name of the resource, or you must specify the
model in the BfgResource::$model parameter or override the
public static function getResource(): mixed.
Now consider the only scope, where we accept all the parameters sequentially:
... public static function onlyScope($model, ...$fields): mixed { return $model?->only($fields); } ...
... public static function paginateScope( $model, int $perPage = null, string $pageName = 'page', int $page = null, ...$columns ): \Illuminate\Contracts\Pagination\LengthAwarePaginator { /** @var Model $model */ return $model->paginate($perPage, $columns ?: ['*'], $pageName, $page); } ...
Thus, we first get the entire list, and then consistently, and the validation of the
required parameters will pass by the PHP means.
The same Rout resource takes various query methods, for such methods there are individual scope
We formally alike add the method name in the name of the updatePostScope function - for post
Default scopes
For more convenience, in the set there are already ready-made scope which I can make it easier for you

Policy
To protect with Laravel Policy, I added you attributes that are responsible for it.
CanResource
Attribute for checking resource.
#[GetResource, CanResource] class DirectorResource extends BfgResource { ... }
Will check the id-field-user.
CanScope
Attribute for checking scope.
use Bfg\Resource\Attributes\CanScope; ... #[CanScope] public static function myScope($model, array $data, int $id): mixed { return $model; } ...
Since this conditional resource UserResource More will be checked by the politics my-user
Or you can specify your own #[CanScope('my-policy')].
CanFields
Attribute for checking field or fields. It only applies to the map parameter.
... #[CanFields([ 'id', 'name' ])] protected array $map = [ 'id', 'name', ]; // Or #[CanFields('id', 'name')] protected array $map = [ 'id', 'name', ]; ...
Will check the id-field-user and name-field-user.
... #[CanFields([ 'id', 'name' => 'my-policy' ])] protected array $map = [ 'id', 'name', ]; ...
Will check the id-field-user and my-policy.
If the policy field does not fit, it is simply not present in the overall list.
CanUser
Checks the user fields with resource fields.
#[GetResource, CanUser] class DirectorResource extends BfgResource { ... }
Will check resource->user_id == auth->user->id.
Or you can manually specify which fields to check.
#[GetResource, CanUser('local_field', 'user_field')] class DirectorResource extends BfgResource { ... }
Will check resource->local_field == auth->user->user_field.
If the policy does not fit, it is simply not present in the overall list, but reserved in the collection.
PHP api
To create one instance:
UserResource::make(User::first());
To create a collection of instances:
UserResource::collection(User::get());
Method for autodetect and create instance for collection or single resource:
UserResource::create(User::first()): static; // or UserResource::create(User::get()): BfgResourceCollection;
Inside helpers
isPrent()- Is root nested level.isChild()- Is child nested level.isNesting(int $needleNested)- Is nested level equals needle nested.isCollected()- If the process is a challenge of this resource from the collection.nesting()- Get nested level.
PHP Class scope api
To call scope In PHP, you can use the static constructor:
use App\Http\Resources\UserResource; ... // For get resource instance UserResource::scope('where', 'name', 'admin', 'first'); // For get resource array result UserResource::scope('where', 'name', 'admin', 'first')->toFields(); ...
You can get the object for use
use App\Http\Resources\UserResource; ... // For get resource array result UserResource::use('where', 'name', 'admin', 'first'); // object with data ...
