A simple wrapper to use CRUD operations in each model.
Wildfire is a simple wrapper for the Query Builder Class based on Codeigniter 3. It is inspired from the Eloquent ORM of Laravel.
Install Wildfire via Composer:
$ composer require rougin/wildfireCreate a sample database table to be used (e.g., users):
-- Import this script to a SQLite database
CREATE TABLE users (
id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
name TEXT NOT NULL,
age INTEGER NOT NULL,
gender TEXT NOT NULL,
accepted INTEGER DEFAULT 0
);
INSERT INTO users (name, age, gender) VALUES ('Rougin', 20, 'male');
INSERT INTO users (name, age, gender) VALUES ('Royce', 18, 'male');
INSERT INTO users (name, age, gender) VALUES ('Mei', 19, 'female');Then configure the composer_autoload option in config.php:
// ciacme/application/config/config.php
/*
|--------------------------------------------------------------------------
| Composer auto-loading
|--------------------------------------------------------------------------
|
| Enabling this setting will tell CodeIgniter to look for a Composer
| package auto-loader script in application/vendor/autoload.php.
|
| $config['composer_autoload'] = TRUE;
|
| Or if you have your vendor/ directory located somewhere else, you
| can opt to set a specific path as well:
|
| $config['composer_autoload'] = '/path/to/vendor/autoload.php';
|
| For more information about Composer, please visit http://getcomposer.org/
|
| Note: This will NOT disable or override the CodeIgniter-specific
| autoloading (application/config/autoload.php)
*/
$config['composer_autoload'] = __DIR__ . '/../../vendor/autoload.php';[!NOTE] The value of
composer_autoloadshould be thevendordirectory (e.g.,ciacme/vendor/autoload.php).
Next is to extend the model (e.g., User) to the Model class of Wildfire:
// ciacme/application/models/User.php
use Rougin\Wildfire\Model;
class User extends Model
{
}// ciacme/application/controllers/Welcome.php
// Loads the database connection
$this->load->database();
// Enables the inflector helper. It is being used to
// determine the class or the model name to use based
// from the given table name from the Wildfire.
$this->load->helper('inflector');
// Loads the required model/s
$this->load->model('user');WildfireCI_DB_query_builderAfter configuring the application, the Wildfire class can now be used for returning results from the database as Model objects:
// ciacme/application/controllers/Welcome.php
use Rougin\Wildfire\Wildfire;
// Pass the \CI_DB_query_builder instance
$wildfire = new Wildfire($this->db);
// Can also be called to \CI_DB_query_builder
$wildfire->like('name', 'Royce', 'both');
// Returns an array of User objects
$users = $wildfire->get('users')->result();CI_DB_resultAside from using methods of Wildfire, raw SQL queries can also be converted to its Model counterpart:
// ciacme/application/controllers/Welcome.php
use Rougin\Wildfire\Wildfire;
$query = 'SELECT p.* FROM post p';
// Create raw SQL queries here...
$result = $this->db->query($query);
// ...or even the result of $this->db->get()
$result = $this->db->get('users');
// Pass the result as the argument
$wildfire = new Wildfire($result);
// Returns an array of User objects
$users = $wildfire->result('User');Model classThe Model class provides the following properties that helps writing clean code and the said properties also conforms to the properties based on Eloquent ORM.
Updating the $casts property allows the model to cast native types to the specified attributes:
// ciacme/application/models/User.php
class User extends \Rougin\Wildfire\Model
{
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = array('accepted' => 'boolean');
}Without native casts
{
"id": 1,
"name": "Rougin",
"age": "20",
"gender": "male",
"accepted": "0",
}With native casts
{
"id": 1,
"name": "Rougin",
"age": "20",
"gender": "male",
"accepted": false,
}Notice that the value of accepted was changed from string integer ('0') into native boolean (false). If not specified (e.g. age field), all values will be returned as string except the id field (which will be automatically casted as native integer, also if the said column exists) by default.
To hide attributes for serialization, the $hidden property can be used:
// ciacme/application/models/User.php
class User extends \Rougin\Wildfire\Model
{
/**
* The attributes that should be hidden for serialization.
*
* @var array
*/
protected $hidden = array('gender');
}Without hidden attributes
{
"id": 1,
"name": "Rougin",
"age": "20",
"gender": "male",
"accepted": "0",
}With hidden attributes
{
"id": 1,
"name": "Rougin",
"age": "20",
"accepted": "0",
}In this example, the gender field was not included in the result.
Opposite of the $hidden property, the $visible property specifies the fields to be visible in the result:
// ciacme/application/models/User.php
class User extends \Rougin\Wildfire\Model
{
/**
* The attributes that should be visible for serialization.
*
* @var array
*/
protected $visible = array('gender');
}Without visible attributes
{
"id": 1,
"name": "Rougin",
"age": "20",
"gender": "male",
"accepted": "0",
}With visible attributes
{
"gender": "male"
}From the example, only the gender field was displayed in the result because it was the only field specified in the $visible property of the User model.
Similar to Eloquent ORM, Wildfire enables the usage of timestamps by default:
// ciacme/application/models/User.php
class User extends \Rougin\Wildfire\Model
{
/**
* Allows usage of timestamp fields ("CREATED_AT", "UPDATED_AT").
*
* @var boolean
*/
protected $timestamps = true;
}When enabled, it will use the constants CREATED_AT and UPDATED_AT for auto-populating them with current timestamps. To modify the names specified in the specified timestamps, kindly create the specified constants to the model (e.g., User):
// ciacme/application/models/User.php
class User extends \Rougin\Wildfire\Model
{
/**
* The name of the "created at" column.
*
* @var string
*/
const CREATED_AT = 'created_at';
/**
* The name of the "updated at" column.
*
* @var string
*/
const UPDATED_AT = 'updated_at';
}[!NOTE] Auto-populating of timestamps in the specified constants is used in
WritableTrait.
When accessing an attribute through the model, Wildfire uses the same mechanism as from Eloquent ORM to return the requested attribute from the $attributes property. To customize the output of an attribute (e.g., converting an attribute to a date format), add a method inside the Model with a name format get_[ATTRIBUTE]_attribute:
// ciacme/application/models/User.php
class User extends \Rougin\Wildfire\Model
{
/**
* @return string
*/
public function get_created_at_attribute()
{
return date('d F Y H:i:sA', strtotime($this->attributes['created_at']));
}
}After creating a method for the specified attribute, the Model class will call the said method (e.g., get_created_at_attribute) if the specified attribute is accessed (e.g., $user->created_at).
Wildfire provides traits that are based from the libraries of Codeigniter 3 such as Form Validation and Pagination Class. They are used to easily attach the specified functionalities of Codeigniter 3 to a model.
PaginateTraitThe PaginateTrait is used to easily create pagination links within the model:
// ciacme/application/models/User.php
use Rougin\Wildfire\Traits\PaginateTrait;
class User extends \Rougin\Wildfire\Model
{
use PaginateTrait;
// ...
}// ciacme/application/controllers/Welcome.php
// Create a pagination links with 10 as the limit and
// 100 as the total number of items from the result.
$result = $this->user->paginate(10, 100);
$data = array('links' => $result[1]);
$offset = $result[0];
// The offset can now be used for filter results
// from the specified table (e.g., "users").
$items = $this->user->get(10, $offset);The $result[0] returns the computed offset while $result[1] returns the generated pagination links:
// ciacme/application/views/users/index.php
<?php echo $links; ?>To configure the pagination library, the $pagee property must be defined in the Model:
// ciacme/application/models/User.php
use Rougin\Wildfire\Traits\PaginateTrait;
class User extends \Rougin\Wildfire\Model
{
use PaginateTrait;
// ...
/**
* Additional configuration to Pagination Class.
*
* @link https://codeigniter.com/userguide3/libraries/pagination.html#customizing-the-pagination
*
* @var array<string, mixed>
*/
protected $pagee = array(
'page_query_string' => true,
'use_page_numbers' => true,
'query_string_segment' => 'p',
'reuse_query_string' => true,
);
}[!NOTE] Please see the documentation of Pagination Class to get the list of its available configuration.
ValidateTraitThis trait is used to simplify the specifying of validation rules to a model:
// ciacme/application/models/User.php
use Rougin\Wildfire\Traits\ValidateTrait;
class User extends \Rougin\Wildfire\Model
{
use ValidateTrait;
// ...
}When used, the $rules property of the model must be defined with validation rules that conforms to the Form Validation specification:
// ciacme/application/models/User.php
use Rougin\Wildfire\Traits\ValidateTrait;
class User extends \Rougin\Wildfire\Model
{
use ValidateTrait;
// ...
/**
* List of validation rules.
*
* @link https://codeigniter.com/userguide3/libraries/form_validation.html#setting-rules-using-an-array
*
* @var array<string, string>[]
*/
protected $rules = array(
array('field' => 'name', 'label' => 'Name', 'rules' => 'required'),
array('field' => 'email', 'label' => 'Email', 'rules' => 'required'),
);
}[!NOTE] Kindly check its documentation for the available rules that can be used to the
$rulesproperty.
To do a form validation, the validate method must be called from the model:
// ciacme/application/controllers/Welcome.php
/** @var array<string, mixed> */
$input = $this->input->post(null, true);
$valid = $this->user->validate($input);If executed with a view, the validation errors can be automatically be returned to the view using the form_error helper:
// ciacme/application/views/users/create.php
<?= form_open('users/create') ?>
<div>
<!-- ... -->
<?= form_error('name') ?>
</div>
<div>
<!-- ... -->
<?= form_error('email') ?>
</div>
<!-- ... -->
<?= form_close() ?>WritableTraitThe WritableTrait is a special trait that enables the model to perform CRUD operations:
// ciacme/application/models/User.php
use Rougin\Wildfire\Traits\WritableTrait;
class User extends \Rougin\Wildfire\Model
{
use WritableTrait;
// ...
}If added, the model can now perform actions such as create, delete, and update:
// ciacme/application/controllers/Welcome.php
/** @var array<string, mixed> */
$input = $this->input->post(null, true);
// Create the user with the given input
$this->user->create($input);
// Delete the user based on its ID.
$this->user->delete($id);
// Update the user details with its input
$this->user->update($id, $input);[!NOTE] When using this trait, the
CREATED_ATandUPDATED_ATconstants will be populated if the$timestampsproperty of a model is enabled.
WildfireTraitSimilar to WritableTrait, the WildfireTrait allows the model to use methods directly from the Wildfire class:
// ciacme/application/models/User.php
use Rougin\Wildfire\Traits\WildfireTrait;
class User extends \Rougin\Wildfire\Model
{
use WildfireTrait;
// ...
}Adding it to a model enables the methods such as find and get methods without specifying the database table:
// ciacme/application/controllers/Welcome.php
/** @var array<string, mixed> */
$input = $this->input->post(null, true);
// Find the user based on the given ID
$item = $this->user->find($id);
// Return a filtered list of users based on
// the specified limit and its given offset
$items = $this->user->get($limit, $offset);v0.5.0 releaseThe new release for v0.5.0 will be having a backward compatibility break (BC break). With this, some functionalities from the earlier versions might not be working after upgrading. This was done to increase the maintainability of the project while also adhering to the functionalities for both Codeigniter 3 and Eloquent ORM. Please see the UPGRADING page for the said breaking changes.
