I had my api ready and faced the problem of converting them into rest routes with api and version prefixs using the cakephp Router::mapResources function that was provided by default by CakePhp,
My api was intially,
http://www.xyz.com/controller/
supporting basic rest routes and I wanted it to be in the form
http://www.xyz.com/api/version_number/controller/action
that would support basic rest routes with prefix including api and version number.
To achieve this there are two ways:
- Create routes using Router::connect for each function and list them down manually in your routes.php file.
- The second options (which I used) is a small hack was made in the core cakephp2 lib Router class mapResource function located at Path to CakePhp App Folder/lib/Cake/Routing/Router.php as follows:
Intially the function was as follows:
/**
* Creates REST resource routes for the given controller(s). When creating resource routes
* for a plugin, by default the prefix will be changed to the lower_underscore version of the plugin
* name. By providing a prefix you can override this behavior.
*
* ### Options:
*
* - 'id' - The regular expression fragment to use when matching IDs. By default, matches
* integer values and UUIDs.
* - 'prefix' - URL prefix to use for the generated routes. Defaults to '/'.
* - 'controller' - If an alias for the controller is being provided, then controller name(in plural and lowercase) should be specified
* - 'plugin' - If the controller specified is a plugin, then the name of the plugin should be provided.
*
* @param string|array $controller A controller name or array of controller names (i.e. "Posts" or "ListItems")
* @param array $options Options to use when generating REST routes
* @return array Array of mapped resources
*/
public static function mapResources($controller, $options = array()) {
$hasPrefix = isset($options['prefix']);
$options += array(
'connectOptions' => array(),
'prefix' => '/',
'id' => self::ID . '|' . self::UUID
);
$prefix = $options['prefix'];
$connectOptions = $options['connectOptions'];
unset($options['connectOptions']);
if (strpos($prefix, '/') !== 0) {
$prefix = '/' . $prefix;
}
if (substr($prefix, -1) !== '/') {
$prefix .= '/';
}
foreach ((array)$controller as $name) {
list($plugin, $name) = pluginSplit($name);
$urlName = Inflector::underscore($name);
$plugin = Inflector::underscore($plugin);
if ($plugin && !$hasPrefix) {
$prefix = '/' . $plugin . '/';
}
foreach (self::$_resourceMap as $params) {
$url = $prefix . $urlName . (($params['id']) ? '/:id' : '');
Router::connect($url,
array(
'plugin' => !isset($options['plugin']) ? $plugin : $options['plugin'],
'controller' => !isset($options['controller']) ? $urlName : $options['controller'],
'action' => $params['action'],
'[method]' => $params['method']
),
array_merge(
array('id' => $options['id'], 'pass' => array('id')),
$connectOptions,
$options['param']
)
);
}
self::$_resourceMapped[] = $urlName;
}
return self::$_resourceMapped;
}
Change it to the following(replace that code with the following one):
/**
* Creates REST resource routes for the given controller(s). When creating resource routes
* for a plugin, by default the prefix will be changed to the lower_underscore version of the plugin
* name. By providing a prefix you can override this behavior.
*

* - 'id' - The regular expression fragment to use when matching IDs. By default, matches
* integer values and UUIDs.
* - 'prefix' - URL prefix to use for the generated routes. Defaults to '/'.
* - 'controller' - If an alias for the controller is being provided, then controller name(in plural and lowercase) should be specified
* - 'plugin' - If the controller specified is a plugin, then the name of the plugin should be provided.
*
* @param string|array $controller A controller name or array of controller names (i.e. "Posts" or "ListItems")
* @param array $options Options to use when generating REST routes
* @return array Array of mapped resources

$hasPrefix = isset($options['prefix']);
$options += array(

);
$prefix = $options['prefix'];
$connectOptions = $options['connectOptions'];
unset($options['connectOptions']);
if (strpos($prefix, '/') !== 0) {
$prefix = '/' . $prefix;
}
if (substr($prefix, -1) !== '/') {
$prefix .= '/';
}
foreach ((array)$controller as $name) {

$urlName = Inflector::underscore($name);
$plugin = Inflector::underscore($plugin);
if ($plugin && !$hasPrefix) {
$prefix = '/' . $plugin . '/';
}
foreach (self::$_resourceMap as $params) {
$url = $prefix . $urlName . (($params['id']) ? '/:id' : '');
Router::connect($url,
array(
//Router hack to support alias
'plugin' => !isset($options['plugin']) ? $plugin : $options['plugin'],
'controller' => !isset($options['controller']) ? $urlName : $options['controller'],
//Router hack to support alias
/**
* Original Routes
* 'plugin' => $plugin,
* 'controller' => $urlName,
*/
'action' => $params['action'],
'[method]' => $params['method']
),
array_merge(
array('id' => $options['id'], 'pass' => array('id')),
$connectOptions,
$options['param']

}
self::$_resourceMapped[] = $urlName;
}
return self::$_resourceMapped;
}
To use the new mapResources, in your router.php file you can use the function as follows:
Router::mapResources('Controllername', array('prefix' => '/api/:apiVersion/', 'param' => array('api' => 'api', 'apiVersion' => 'v1|v2|')));
Furthermore if you would like to give an alias to the controller as follows: All request for sheets should be handled by the controller tables with default rest routes, you can write mapResources in router.php as follows:
Router::mapResources('sheets', array('prefix' => '/api/:apiVersion/', 'param' => array('api' => 'api', 'apiVersion' => 'v1|v2|'), 'controller' => 'tables'));
