php - CakePHP - How to change default plugin router config -

i new in cakephp. have added plugin in cake app, , name "admin". it's working fine, when use "localhost/admin/..." access it. question is, want hide /admin users, instance, want use "localhost/console/..." replace default route config. googled lot, never got answer. how change default route config of plugin in cakephp? thanks. if want applicable plugin controllers/actions, need little more verbose. try: router::connect('/console/:controller/:action/*', array('plugin'=>'admin')); but if that's want, you're better off renaming "admin" plugin "console". re-routing plugin controllers , actions make debugging not fun. :)

html - Struts tags substitution -

i wondering if replace struts tags html, when output data. projects in company still using struts tags seems it's not easy use compared html. of course can, long duplicate: whatever html emitted tag, and... ...whatever java logic tag implements. for example, custom form tags is: emit form elements (possibly embedded in other markup depending on s2 theme) set form element value action property display error messages relating form element (depending on s2 theme) some tags don't emit html of own, example, <s:iterator> loops on collection, pushes each object onto value stack, , processes tag body other jsp custom tag. should reproduce existing framework logic , write either: a lot more html, or... ...your own complete suite of custom tags? i doubt it, there valid usecases doing so–i can't think of them.
