Introduction

Data Entities is a library that allows you to execute stored procedures in Sqlserver easily. It is a wrapper around the Laravel's DB Facade.

Installation

You can install the package via composer:

composer require bit-mx/data-entities

Setup

You need to publish the configuration file to set the connection name.

php artisan vendor:publish --provider="BitMx\DataEntities\DataEntitiesServiceProvider" --tag="config"

This command will create a new configuration file in the config directory.

return [
    'database' => env('DATA_ENTITIES_CONNECTION', 'sqlsrv'),
];

Compatibility

This package is compatible with Laravel 10.x and above.

Due laravel 11 requires php 8.2, this package is compatible with php 8.2 and above.

Getting Started

Create a Data Entity

To create a Data Entity, you need to extend the DataEntity class and implement the resolveStoreProcedure method with the name of the stored procedure you want to execute.

You can also override the defaultParameters method to set the default parameters for the stored procedure.

namespace App\DataEntities;

use DataEntities\DataEntity;
use BitMx\DataEntities\Enums\Method;
use BitMx\DataEntities\Enums\ResponseType;
use BitMx\DataEntities\Responses\Response;
use Illuminate\Support\Collection;

class GetAllPostsDataEntity extends DataEntity
{
    protected ?Method $method = Method::SELECT;
    
    protected ?ResponseType $responseType = ResponseType::SINGLE;
    
    public function __construct(
        protected int $authorId,
    ) 
    {
    
    }
    
    #[\Override]
    public function resolveStoreProcedure(): string
    {
        return 'spListAllPost';
    }

    #[\Override]
    public function defaultParameters(): array
    {
        return [
            'author_id' => $this->authorId,
        ];
    } 
}

You can also use the parameters method to set the parameters for the stored procedure.

use App\DataEntities\GetAllPostsDataEntity;

$dataEntity = new GetAllPostsDataEntity(1);

$dataEntity->parameters()->add('tag', 'laravel');

The ResponseType enum has two options: SINGLE and COLLECTION.

SINGLE is used when the stored procedure returns a single row, and COLLECTION is used when the stored procedure returns multiple rows.

You can use the artisan command to create a new Data Entity:

php artisan make:data-entity GetAllPostsDataEntity

This command will create a new Data Entity in the app/DataEntities directory.

Connection

You can set the connection name overriding the resolveDatabaseConnection method.

namespace App\DataEntities;

use DataEntities\DataEntity;
use BitMx\DataEntities\Enums\Method;
use BitMx\DataEntities\Enums\ResponseType;

class GetAllPostsDataEntity extends DataEntity
{
    ...
    
    #[\Override]
    public function resolveDatabaseConnection(): string
    {
        return 'sqlsrv';
    }
}

Execute the Data Entity

To execute the Data Entity, you need to call the execute method on the Data Entity instance.

use App\DataEntities\GetAllPostsDataEntity;

$dataEntity = new GetAllPostsDataEntity(1);

$response = $dataEntity->execute();

$data = $response->getData();

The execute method returns a Response object that contains the data returned by the stored procedure.

Mutators

You can use the mutators method to transform the parameters before sending them to the Store Procedure.

namespace App\DataEntities;

use Carbon\Carbon;use DataEntities\DataEntity;
use BitMx\DataEntities\Enums\Method;
use BitMx\DataEntities\Enums\ResponseType;

class GetAllPostsDataEntity extends DataEntity
{
    ...
    
    #[\Override]
    public function defaultParameters(): array
    {
        return [
            'date' => Carbon::now(),
        ];
    } 
    
     /**
     * @return array<string, string>
     */
     #[\Override]
    protected function mutators(): array
    {
        return [
            'date' => 'datetime:Y-m-d H:i',
        ];
    }
}

This will transform the date parameter to a formatted date string before sending it to the stored procedure.

Available mutators

• datetime: : Converts the value to a datetime string using the specified format. You can pass a format as an argument to the cast. Examples:

  • datetime Returns Y-m-d H:i:s
  • datetime:Y-m-d
  • datetime:H:i:s
  • datetime:Y-m-d H:i:s

• date: : Converts the value to a date Y-m-d

• bool: : Converts the value to a boolean in int. Example: If the value is true, it will be converted to 1, and if it is false, it will be converted to 0.

• int: : Converts the value to an integer.

• float: : Converts the value to a float. You can pass the number of decimals as an argument to the cast. Example:

  - `float` Returns a float with 2 decimals.
  - `float:4` Returns a float with 4 decimals.
  - `float:0` Returns an integer.
  

• string: : Converts the value to a string.

• json: : Converts the value to a json string. : Example:

  : - if you pass an array, it will be converted to a json string.

  • [1, 2,4] will be converted to "[1,2,4]"
  • ['name' => 'John'] will be converted to '{"name":"John"}'
  • You can pass the JSON options as an argument to the cast.
  • 'json:'. JSON_PRETTY_PRINT will return the json string with the JSON_PRETTY_PRINT option.

Custom mutators

You can create custom mutators by implementing the Mutable interface.

namespace BitMx\DataEntities\Mutators;

use BitMx\DataEntities\Contracts\Mutable;

class CustomMutator implements Mutable
{
    /**
     * {@inheritDoc}
     */
    public function transform(string $key, mixed $value, array $parameters): mixed
    {
        
    }
}

You can create a new cast using the artisan command.

php artisan make:data-entity-mutator CustomMutator

Accessors

You can use the accessors method to transform the data returned by the stored procedure.

namespace App\DataEntities;

use Carbon\Carbon;use DataEntities\DataEntity;
use BitMx\DataEntities\Enums\Method;
use BitMx\DataEntities\Enums\ResponseType;

class GetAllPostsDataEntity extends DataEntity
{
    ...
    
    #[\Override]
    public function defaultParameters(): array
    {
        return [
            'date' => Carbon::now(),
        ];
    } 
    
     /**
     * @return array<string, string>
     */
     #[\Override]
    protected function accessors(): array
    {
        return [
            'contact_id' => 'integer',
        ];
    }
}

This will transform the contact_id key to an integer before returning the data.

Available accessors

• datetime: : Converts the value to a DateTime instance.

• datetime_immutable: : Converts the value to a DateTimeImmutable instance.

• bool: : Converts the value to a boolean Example: If the value is 1, it will be converted true

• int: : Converts the value to an integer.

• float: : Converts the value to a float

• string: : Converts the value to a string.

• array: : Converts the value from a json string to an array.

  • object: : Converts the value from a json string to an object.

• collection: : Converts the value from a json string to a Laravel Collection.

Custom accessor

You can create custom accessors by implementing the Accessable interface.

namespace BitMx\DataEntities\Accessors;

use BitMx\DataEntities\Contracts\Accessable;

class CustomAccessor implements Accessable
{
    /**
     * {@inheritDoc}
     */
    public function get(string $key, mixed $value, array $data): mixed
    {
        
    }
}

You can create a new accessor using the artisan command.

php artisan make:data-entity-accessor CustomAccessor

Response useful methods

The Response object has some useful methods to work with the data returned by the stored procedure.

data

The getData method returns the data returned by the stored procedure as an array.

$data = $response->data();

Data with a key

You can get the data with a key

$data = $response->data('key');

Data with a key and a default value

You can get the data with a key and a default value

$data = $response
    ->data('key', 'default value');

As object

You can get the data as an object

$data = $response->object();

As collection

You can get the data as a collection

$data = $response->collect();

success

The success method returns true if the stored procedure was executed successfully, and false otherwise.

if ($response->success()) {
    // The stored procedure was executed successfully
} else {
    // There was an error executing the stored procedure
}

failed

The fail method returns true if the stored procedure failed, and false otherwise.

if ($response->failed()) {
    // There was an error executing the stored procedure
} else {
    // The stored procedure was executed successfully
}

throw

By default, the Response object won't throw an exception if the stored procedure fails. You can throw an exception manually using the throw method.

$response->throw();

Boot

You can use the boot method to execute code before and after the stored procedure is executed.

namespace App\DataEntities;

use BitMx\DataEntities\PendingQuery;
use DataEntities\DataEntity;
use BitMx\DataEntities\Enums\Method;
use BitMx\DataEntities\Enums\ResponseType;
use BitMx\DataEntities\Responses\Response;
use Illuminate\Support\Collection;


class GetAllPostsDataEntity extends DataEntity
{
    protected ?Method $method = Method::SELECT;
    
    protected ?ResponseType $responseType = ResponseType::SINGLE;
    
    ...
    
    #[\Override]
    public function boot(PendingQuery $pendingQuery): void
    {
        $pendingQuery->parameters()->all('tag', 'laravel');
    }
    
}

Traits

You can use traits to add functionality to your Data Entities. Add the method bootTrait to the Data Entity to use the trait.

trait Taggable
{
    public function bootTaggable(PendingQuery $pendingQuery): void
    {
        $pendingQuery->parameters()->add('tag', 'laravel');
    }
}

The bootTaggable method will be called before the stored procedure is executed.

Data Transfer objects

You can use Data Transfer objects to map the data returned by the stored procedure to a PHP object.

namespace App\Data;


class PostDat
{
    public function __construct(
        public int $id,
        public string $title,
        public string $content,
    ) 
    {
    
    }
}

namespace App\DataEntities;

use DataEntities\DataEntity;
use BitMx\DataEntities\Enums\Method;
use BitMx\DataEntities\Enums\ResponseType;
use BitMx\DataEntities\Responses\Response;
use Illuminate\Support\Collection;
use App\Data\PostData;

class GetPostDataEntity extends DataEntity
{
    protected ?Method $method = Method::SELECT;
    
    protected ?ResponseType $responseType = ResponseType::SINGLE;
    
    public function __construct(
        protected int $postId,
    ) 
    {
    
    }
    
    #[\Override]
    public function resolveStoreProcedure(): string
    {
        return 'spListPost';
    }

    #[\Override]
    public function defaultParameters(): array
    {
        return [
            'post_is' => $this->postId,
        ];
    } 
    
    public function createDtoFromResponse(Response $response): PostData
    {
        $data = $response->getData();
        
        return new PostData(
            id: $data['id'],
            title: $data['title'],
            content: $data['content'],
        );
    }
}

You can get the dto from the response using the dto method.

use App\DataEntities\GetPostDataEntity;

$dataEntity = new GetPostDataEntity(1);

$response = $dataEntity->execute();

/** @var PostData $post */
$post = $response->dto();

Debugging

You cal call dd and ddRaw methods to debug the query sent to the database.

use App\DataEntities\GetPostDataEntity;

$dataEntity = new GetPostDataEntity(1);

$dataEntity->dd();

$dataEntity->ddRaw();

Testing

You can create integration tests for your Data Entities easily.

Mocking the Data Entity

You can mock the Data Entity using the DataEntity::fake method.

use App\DataEntities\GetPostDataEntity;
use BitMx\DataEntities\DataEntity;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    DataEntity::fake([
        GetPostDataEntity::class => MockResponse::make([
            'id' => 1,
            'title' => 'Post title',
            'content' => 'Post content',
        ]),
    ]);

    $dataEntity = new GetPostDataEntity(1);

    $response = $dataEntity->execute();

    $post = $response->dto();

    expect($post->id)->toBe(1);
    expect($post->title)->toBe('Post title');
    expect($post->content)->toBe('Post content');
});

When using the fake method, the execute method will return the data specified in the MockResponse::make method and won't execute the stored procedure.

Assertions

You can use the assert method to assert that the Data Entity was executed.

use App\DataEntities\GetPostDataEntity;
use BitMx\DataEntities\DataEntity;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    DataEntity::fake([
        GetPostDataEntity::class => MockResponse::make([
            'id' => 1,
            'title' => 'Post title',
            'content' => 'Post content',
        ]),
    ]);

    $dataEntity = new GetPostDataEntity(1);

    $response = $dataEntity->execute();

    $post = $response->dto();

    DataEntity::assertExecuted(GetPostDataEntity::class);
});

Assertions

You can use the following assertions:

• assertExecuted: Assert that the Data Entity was executed.
• assertNotExecuted: Assert that the Data Entity was not executed.
• assertExecutedCount: Assert that the Data Entity was executed a specific number of times.
• assertExecutedOnce: Assert that the Data Entity was executed once.

Using factories

You can use factories to create fake data for your Data Entities.

namespace Tests\DataEntityFactories;

use BitMx\DataEntities\Factories\DataEntityFactory;

class PostDataEntityFactory extends DataEntityFactory
{
    /**
     * {@inheritDoc}
     */
    public function definition(): array
    {
        return [
            'id' => $this->faker->unique()->randomNumber(),
            'title' => $this->faker->sentence(),
            'content' => $this->faker->paragraph(),
        ];
    }
}

To create a factory you should extend the DataEntityFactory class and implement the definition method.

You can use the faker property to generate fake data.

use App\DataEntities\GetPostDataEntity;
use Tests\DataEntityFactories\PostDataEntityFactory;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    $dataEntity = MockResponse::make(PostDataEntityFactory::new());

    $response = $dataEntity->execute();

    $post = $response->dto();

    expect($post->id)->toBe(1);
    expect($post->title)->toBe('Post title');
    expect($post->content)->toBe('Post content');
});

You can pass directly the factory to the MockResponse::make method. or you can create an array with the create method.

use App\DataEntities\GetPostDataEntity;
use Tests\DataEntityFactories\PostDataEntityFactory;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    $dataEntity = MockResponse::make(PostDataEntityFactory::new()->create());

    $response = $dataEntity->execute();

    $post = $response->dto();

    expect($post->id)->toBe(1);
    expect($post->title)->toBe('Post title');
    expect($post->content)->toBe('Post content');
});

You can also use the count method to create an array of fake data.

use App\DataEntities\GetPostDataEntity;
use Tests\DataEntityFactories\PostDataEntityFactory;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    $dataEntity = MockResponse::make(PostDataEntityFactory::new()->count(10));

    $response = $dataEntity->execute();

    $posts = $response->dto();

    expect($posts)->toHaveCount(10);
});

You can use the state method to change the default values of the factory.

use App\DataEntities\GetPostDataEntity;
use Tests\DataEntityFactories\PostDataEntityFactory;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    $dataEntity = MockResponse::make(PostDataEntityFactory::new()->state([
        'title' => 'Custom title',
    ]));

    $response = $dataEntity->execute();

    $post = $response->dto();

    expect($post->title)->toBe('Custom title');
});

Or create a new method in the factory to change the default values.

namespace Tests\DataEntityFactories;

use BitMx\DataEntities\Factories\DataEntityFactory;

class PostDataEntityFactory extends DataEntityFactory
{
    /**
     * {@inheritDoc}
     */
    public function definition(): array
    {
        return [
            'id' => $this->faker->unique()->randomNumber(),
            'title' => $this->faker->sentence(),
            'content' => $this->faker->paragraph(),
        ];
    }
    
    public function withPublishedDate(array $state): DataEntityFactory
    {
        return $this->state([
            'published_date' => now(),
        ]);
    }
}

use App\DataEntities\GetPostDataEntity;
use Tests\DataEntityFactories\PostDataEntityFactory;
use BitMx\DataEntities\Responses\MockResponse;

it('should get the post', function () {
    $dataEntity = MockResponse::make(PostDataEntityFactory::new()->withPublishedDate());

    $response = $dataEntity->execute();

    $post = $response->dto();

    expect($post->published_date)->toBe(now());
});

You can create a new factory using the artisan command.

php artisan make:data-entity-factory PostDataEntityFactory

This command will create a new factory in the tests/DataEntityFactories directory.
