If you’re using DD4T, you know that you have to assign metadata to your templates. It is through this metadata that DD4T knows which view to use to render a given page or component presentation.
Now, DD4T can also work without metadata on templates. How? Simple: by using a naming convention. Just give your view the same name as your template, and you’re done. This is in line with the ‘convention over configuration’ mechanism which is embraced by the MVC world.
There is one caveat: if your template name contains spaces, these are removed before looking up the view. So if your page template is called ‘Standard Mobile’, the file containing the view should be named ‘StandardMobile.cshtml’.
Of course, the good old metadata still works, and will continue to be supported as a way to override the default.
