Service laravel

Library that helps to separate the business rule part of the control. Leaving control leaner.

---

Requirements

• PHP 7.0 or newer;
• Laravel 5.5 or newer;

---

Installation

composer require fernandozueet/service-laravel

---

Register the commands

File: app/Console/Kernel.php

protected $commands = [
    \FzService\Console\ServiceCommand::class,
    \FzService\Console\ResourceCommand::class,
];

---

Create a class of resource

The resource class is overwritten and gets a new customization feature from the fields that are returned.

You do not need to enter the resource prefix.

php artisan fzservice:make:resource User

Class created:

<?php

namespace App\Http\Resources;

use FzService\JsonResource;

class UserResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
    	$return = parent::toArray($request);

    	return $this->mountFields($return);
    }
}

How to use the filter?

\App\Resources\UserResource::collection(\App\User::paginate(), ['fields' => 'user' => 'id,name']);

---

Create a class of service

You do not need to enter the service prefix.

php artisan fzservice:make:service User

Class created:

<?php

namespace App\Services;

use FzService\Service;
use App\Models\User;
use App\Http\Resources\UserResource;

class UserService extends Service
{
    /**
    * Model class
    *
    * @var \App\Models\User
    */
    protected $modelClass = User::class;

    /**
     * Read all rows
     *
     * @param array $params
     * @param boolean $collection
     * @return array|stdClass
     */
    public function readAll(array $params = [], bool $collection = true)
    {
    	return $this->mountRead(function() use ($params) {

            //

        }, $params, $collection ? UserResource::class : null, []);
    }

}

Service Read

Method to assist in the assembly of queries eloquent.

<?php

namespace App\Services;

use FzService\Service;
use App\Models\User;
use App\Http\Resources\UserResource;

class UserService extends Service
{
    /**
    * Model class
    *
    * @var \App\Models\User
    */
    protected $modelClass = User::class;

    /**
     * Read all rows
     *
     * @param array $params
     * @param boolean $collection
     * @return array|stdClass
     */
    public function readAll(array $params = [], bool $collection = true)
    {
    	return $this->mountRead(function() use ($params) {

            //wheres
            if(!empty($params['id'])) {
                $this->modelClass = $this->modelClass->where('id', $params['id']);
            }
            if(!empty($params['name'])) {
                $this->modelClass = $this->modelClass->where('name', $params['name']);
            }

            //

        }, $params, $collection ? UserResource::class : null, []);
    }

}

Example 1:

Searching by name on page 1

//Service
$userService = \App\Services\UserService();
$result = $userService->readAll(['name' => "User test", 'page' => 1]);

//Code equal to:
$result = \App\Resources\UserResource::collection(\App\User::where('name',$params['name'])->paginate());

Example 2:

Searching by name without pagination

//Service
$userService = \App\Services\UserService();
$result = $userService->readAll(['name' => "User test"]);

//Code equal to:
$result = \App\Resources\UserResource::collection(\App\User::where('name',$params['name'])->get());

Example 3:

Searching by name and sorting by name and last_name ascending

//Service
$userService = \App\Services\UserService();
$result = $userService->readAll(['name' => "User test", 'sort' => 'name,last_name']);

//Code equal to:
$result = \App\Resources\UserResource::collection(\App\User::where('name',$params['name'])->orderBy('name','ASC')->orderBy('last_name','ASC')->get());

Example 4:

Searching by name and sorting by name downward

//Service
$userService = \App\Services\UserService();
$result = $userService->readAll(['name' => "User test", 'sort' => '-name']);

//Code equal to:
$result = \App\Resources\UserResource::collection(\App\User::where('name',$params['name'])->orderBy('name','DESC')->get());

Example 5:

Searching by name on page 1 and choosing the return fields

//Service
$userService = \App\Services\UserService();
$result = $userService->readAll(['name' => "User test", 'page' => 1, 'fields' => [ 'user' => 'id,name' ] ]);

//Code equal to: (this option does not exist in the default laravel resource class)
$result = \App\Resources\UserResource::collection(\App\User::where('name',$params['name'])->paginate());

Disabling default methods:

Default methods: paginate and sort

public function readAll(array $params = [], bool $collection = true)
{
    return $this->mountRead(function() use ($params) {

        //

    }, $params, $collection ? UserResource::class : null, ['paginate','sort']);
}

Disabling Resource Class:

To disable the resource class simply enter the null value.

public function readAll(array $params = [], bool $collection = true)
{
    return $this->mountRead(function() use ($params) {

        //

    }, $params, null, []);
}

Service Insert

Method to insertion data eloquent.

insert(array $values, array $exclude = [], array $include = [])

or

create(array $values, array $exclude = [], array $include = [])

Example 1:

Inserting and returning an array with the entered data

//Service
$userService = \App\Services\UserService();
$result = $userService->insert(['name' => "User test", "last_name" => 'other name']);

//Insert through the Create method (declare fields to insert into the model)
$result = $userService->create(['name' => "User test", "last_name" => 'other name']);

//Code equal to:
$model = new \App\User();
$model->name = 'User test';
$model->last_name = 'other name';
$model->save();
$result = $model->toArray();

Example 2:

Inserting and returning an array with the entered data.

Deleting or adding a field from the returned data.

//Service - exclude return fields
$userService = \App\Services\UserService();
$result = $userService->insert(['name' => "User test", "last_name" => 'other name'], false, ['id','name']);

//Service - visible return fields
$userService = \App\Services\UserService();
$result = $userService->insert(['name' => "User test", "last_name" => 'other name'], false, [], ['id','name']);

//Code equal to:
$model = new \App\User();
$model->name = 'User test';
$model->last_name = 'other name';
$model->save();
$result = $model->makeHidden(['id','name'])->toArray(); //exclude return fields
$result = $model->makeVisible(['id','name'])->toArray(); //visible return fields

---

Service Update

Method to update data eloquent.

updateById(int $id, array $values, array $exclude = [], array $include = [])

Example:

//Service
$userService = \App\Services\UserService();
$result = $userService->updateById(1, ['name' => "New name"]);

$model = \App\User::where('id', 1);
$model->name = 'New name';
$model->save();
$result = $model->toArray();

---

Service Delete

Method to delete data eloquent.

deleteById(int $id)

Example:

//Service

Useful methods

File: \FzService\Service.php

//Model
$this->modelClass;

//Create eloquent model instance
$this->newQuery();

//Set value field (array $params)
$this->setValuesModel(['name' => 'User test']);

//Save model (array $exclude = [], array $include = [], bool $returnArray = true)
$this->saveModel();

//Filter model (filtersModel(array $exclude = [], array $include = [], bool $returnArray = true))
