Grails relative path to controllers view folder

Having a Grails 2.1 application, where I have a taglibrary for rendering a summary for different controllers, I have an issue pointing at the correct view-folder.

Eg. TestAController and TestBController both have a controller specific view file called summary.gsp in their respective view folders. That is /testa/summary.gsp and /testb/summary.gsp.

How can I my taglib render the summary.gsp that is related to the controller currently in action - I need to set a path like "??/summary-gsp".

I don't want to implement any if/else logic as there could potentially be 10000 controllers using this taglib, all specifying their own summary.gsp.

Is this doable?

The caller should pass in the path to the template as an argument to the tag. If this argument is omitted you could use a convention for locating the template, e.g. 

class MyTagLib {

  def renderSummary = {attrs ->

    def defaultTemplatePath = "/${params.controller}/summary"
    def templatePath = attrs.template ?: defaultTemplatePath
    out << g.render(template: templatePath)
  }
}

You can access the params object in your taglib so:

out << render(template: "/${params.controller}/summary")
