How To Call A Taglib As A Function In A Domain Class

Question

I need to call the Static Resources Plugin (http://www.grails.org/Static+Resources+Plugin) from my domain class.

This works perfectly in a controller:

Most taglibs rely on data from the controller so it's often not possible to reuse them while others concern view logic so often it's not something you would want to put in a domain class.

That said, I'm sure you have your reasons so maybe the source of the taglib will help:

class ResourceTagLib  {

    def externalResourceServerService

    def resourceLinkTo = { attrs ->
        out << externalResourceServerService.uri
        out << '/'
        if(attrs['dir']) {
            out << "${attrs['dir']}/"
        }
        if(attrs['file']) {
            out << "${attrs['file']}"
        }
    }
}

ie inject the externalResourceServerService into your domain class and the rest should be simple.
