Datamapper to Grocery_Crud converter

Hi there,

I'm discovering Grocery CRUD, and I find it really helpful and useful. But I'm already working with Datamapper ORM. So, I was looking for a way to make it work together...

So I created a simple Datamapper extension that I called "GroceryCrud", and that it adds the ->to_grocery() method. It needs some additional coding rules, but it can be really more helpful ;-)

I try to really make a Grocery_Crud object from a Datamapper object. It's note easy but it sounds possible.

Grocery CRUD needs :

Table name : OK
Subject : Can be deducted from table name
Fields configuration : need a special attribute in your Datamapper object
Relationships : can be deducted from Datamapper object's "has_one" and "has_many" attributes

I'm not able yet to import Datamapper's relationships data into Grocery CRUD object. But soon...

Here the "DMZ_GroceryCrud" class, that is the Datamapper extension :

<?php
/**
 * File : application/datamapper/grocerycrud.php
 */

class DMZ_GroceryCrud {
	
	/**
	 * This method converts Datamapper object to Grocery Crud object
	 */
	function to_grocery($object)
	{
		
		// Basic properties
			$table_name =		$object->table;
			$grocery_subject =	(property_exists($object, 'grocery_subject')) ? $object->grocery_subject : ucfirst(str_replace('_', ' ', get_class($object)));
			$grocery_fields =	array();
		
		
		// Fields loading
			if ( property_exists($object, 'grocery_fields' ))
			{
				$object->grocery_fields;
			}
			else
			{
				foreach($object->fields as $field_name)
				{
					$grocery_fields[$field_name] = array();
				}
			}
		
		
		// Building Grocery Crud Object
			$crud = new grocery_CRUD();
			
			$crud->set_table($table_name);
			$crud->set_subject($grocery_subject);
		
		
		// Crud fields settings
			$crud_add_fields =	array();
			$crud_edit_fields =	array();
			$crud_columns =		array();
			$crud_required =	array();
			
			foreach ($grocery_fields as $field_name => $field_config)
			{
				
				foreach ($field_config as $config => $value)
				{
					switch ( $config ) {
						
						case 'display_as':
							$crud->display_as($field_name, $field_config['display_as']);
							break;
						
						
						case 'show_column':
							if ($field_config['show_column']==true) {
								$crud_columns[] = $field_name;
							}
							break;
							
						case 'show_add_field':
							if ($field_config['show_add_field']==true) {
								$crud_add_fields[] = $field_name;
							}
							break;
							
						case 'show_edit_field':
							if ($field_config['show_edit_field']==true) {
								$crud_edit_fields[] = $field_name;
							}
							break;
							
						case 'required':
							if ($field_config['required']==true) {
								$crud_required[] = $field_name;
							}
							break;
							
						
					}
				}
			}
			
			$crud->edit_fields($crud_edit_fields);
			$crud->add_fields($crud_add_fields);
			$crud->columns($crud_columns);
			$crud->required_fields($crud_required);
		// -----
		
		return $crud;
	}
	
}

You just need to activate this extension in Datamapper's configuration.

And here an example of Datamapper object's additional properties :

	public $grocery_subject = 'Serveur';
	public $grocery_fields = array(
		'ip' => array(
			'display_as' =>			'IP address',
			'show_column' =>		true,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			false
		),
		'domain' => array(
			'show_column' =>		true,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			true
		),
		'provider' => array(
			'show_column' =>		true,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			true
		),
		'priority_level' => array(
			'show_column' =>		true,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			true
		),
		'driver' => array(
			'show_column' =>		true,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			true
		),
		'driver_parameters' => array(
			'show_column' =>		false,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			false
		),
		'status' => array(
			'show_column' =>		true,
			'show_edit_field' =>	true,
			'show_add_field' =>		true,
			'required' =>			true
		),
		'total_sent' => array(
			'show_column' =>		true,
			'show_edit_field' =>	false,
			'show_add_field' =>		false,
			'required' =>			false
		)
	);

Feel free to improve this class ;-)
