- `RelTmpl() string`, returns the relative template directory based on the controller's name.
These are useful when dealing with big `controllers`, they help you to keep align with any
future changes inside your application.
Let's refactor our [ProfileController](_examples/mvc/controller-with-model-and-view/main.go) enhancemed by these two new functions.
```go
func (pc *ProfileController) tmpl(relativeTmplPath string) {
// the relative template files directory of this controller.
views := pc.RelTmpl()
pc.Tmpl = views + relativeTmplPath
}
func (pc *ProfileController) match(relativeRequestPath string) bool {
// the relative request path of this controller.
path := pc.RelPath()
return path == relativeRequestPath
}
func (pc *ProfileController) Get() {
// requested: "/profile"
// so relative path is "/" because of the ProfileController.
if pc.match("/") {
// views/profile/index.html
pc.tmpl("index.html")
return
}
// requested: "/profile/browse"
// so relative path is "/browse".
if pc.match("/browse") {
pc.Path = "/profile"
return
}
// requested: "/profile/me"
// so the relative path is "/me"
if pc.match("/me") {
// views/profile/me.html
pc.tmpl("me.html")

}
// requested: "/profile/$ID"

**Using Iris MVC for code reuse**
**Using Iris MVC for code reuse**
By creating components that are independent of one another, developers are able to reuse components quickly and easily in other applications. The same (or similar) view for one application can be refactored for another application with different data because the view is simply handling how the data is being displayed to the user.
