Routing not working in phalcon framework - phalcon

Question

I have many modules and depending upon modules routes are generated dynamically. For explaining purpose I m adding route for just one module. Following are the routes for the users module.
<?php
//1
$router->add('/users',array(
'module' =>'users',
'namespace'=>'Backend\users\Controllers\\',
'controller'=>'index',
'action' => 'index'
));
//2
$router->add('/users/:params/',array(
'module' => 'users',
'namespace'=>'Backend\users\Controllers\\',
'controller'=>'index',
'action' => 'index',
'params'=>1
));
//3
$router->add('/users/:action',array(
'module' => 'users',
'namespace'=>'Backend\users\Controllers\\',
'controller'=>'index',
'action'=>1
));
//4
$router->add('/users/:action/:params',array(
'module' => 'users',
'namespace'=>'Backend\users\Controllers\\',
'controller'=>'index',
'action'=>1,
'params'=>2
));
?>
Lets say the url for the user module is
http://www.example.com/admin/users/
This url matches the very first route and its working as expected. But when we navigate to next page, my url looks like
http://www.example.com/admin/users/2
now the problem is it should match 2nd route, but it matches 4th route. If I move 2nd route all the way down, the above url work, but the url
http://www.example.com/admin/users/search/1 will not work
Can anybody help me make it work?
Thanks

Answer 1

:params is tricky because it will match anything. So /users/:params/ matches both /users/:action and /users/:action/:params, which itself has :params in it - making it a routing mind blow.
As a general rule avoid the mind blow scenario. For example you can put :params at the end of the longest possible match (/users/:action/:params) and then rewrite the shorter routes without any :params in them.
