Hi,
what is the best way to implement some action that should be executed each time a request is made?
My aim is to export some variables layout-wide, so the layout could render some fields like "You are logged in as ${userName}, Server time is ${serverTime}".
I know I can inline code in the gsp, but there should be some better way to execute some operations on each request.
Thanks in advance.
You could use layouts and SiteMesh to do that automagically, but in my project, I've stopped using that, because it also has some drawbacks (like <body onload="foobar()"> no longer working...). I propose you create a template just for this info line and render it wherever appropriate.
I've just found an answer here: http://stackoverflow.com/questions/503279/accessing-the-model-from-a-layout-view-in-grails
Filters is the way to execute some global action.
