Hmmmm nope... not good If I set up controller_prefix well, all links work as expected (have the good urls), BUT actions (such as form submits, editing, etc.) have the wrong url (since they don't have prefix). If I set action_prefix, it messes up everything, the scheme is as follows: http://www.all.hu/CONTROLLER_PREFIX/some_controller/ACTION_PREFIX/some_action ACTION_PREFIX is not needed in normal links, but needed at form submits for example. E.g: http://www.all.hu/CONTR_PREF/categories/ACTION_PREF/show/1 is an URL to show articles in a certain category. in this link ACTION_PREF should be "", so the link is: http://www.all.hu/CONTR_PREF/categories/show/1 But in case of an article editing form, whose submit link is generated automatically from :action => target , the action prefix should have a value. I have _no_ idea how to resolve this :/ Regards, Ochronus Ochronus wrote: > Ok, I found out... > > Instead of application_prefix, I rewrote action_prefix, like: > > protected > def default_url_options(options) > { :controller_prefix => "ochronus/" } > end > > > > Thank you again for your help, David! > > Regards, > Ochronus >
