Question

I know I can specify a controller for root page using "/"(controller: "default") in UrlMappings.groovy, however I would like to make my main layout page (in that case is main.gsp) to access at least one defined controller. I’ve tried "/layouts/main.gsp"(controller: "default") but didn’t work. How can I accomplish it? Thanks!

I found another way to fix my issue. Now I can pass user instance that is comming from session for every action. So every time and everywhere my layout header shows the user information (if user is logged on, of course).

My steps:

1. First of all, create a grails filter;

2. Modify your “after” clousure from the filter created
   to get current user and pass it through to every controller’s action, it suppose to be something like that:

   after = { Map model ->
   
       def user = null
   
       if (!session.isNew()) {
           user = session["user"]
   
           if (user) {
               if (!model)
                   model = [:]
   
               model["user"] = user
           }
       }
   
   }
   

I hope it can be helpful, thanks!
