help with uservoice integration

[Warner Onstine]

Hi all, I'm trying to integrate UserVoice support (UserVoice.com) into
my application. I'm doing SSO, so I need to pass some info along to
their widget.

It's fairly complex so I'm doing all of it server side through a
service. I'm now in a quandary as to how to get this string down to
the actual JavaScript.

I'm sure I'm missing something obvious, but here's what I have:
_uservoice.gsp - which has a variable token I can push into it from a controller
TokenGeneratorService - which builds up the token from the current
logged in user and encodes that to send it back to the UserVoice site
when the feedback button is clicked.

I don't like that this requires that for every page I want this on I
need to add this service call and add the 'token' variable to the
model being passed down to the render.

Can anyone see a better way to do this?

Is it possible for you to use the /views/layout/main.gsp (Sitemesh template) to host the Javascript?  That's run for every page.

You could write a filter that gets invoked on every controller action and add something the model.  We do this to add some standard user info to every page.  Maybe something like this in grails-app/conf/MyFilters.groovy:

class MyFilters {  

    def myService

   

    def filters = {       

        addUserVoiceStuffToModel(controller: '*', action: '*') {

            after = { model ->

                    model?.userVoiceStuff = myService.getUserVoiceStuff()

                }

        }

    }

}

That might work! I have never futzed with filters so I'll give that a
shot and see what happens.
