Server Side Datatable, show foreign key name

RamiroArizpe

I don't know if this is really hard or not but I'm trying to show on my datatable the name of 2 Foreign key's

http://jsfiddle.net/ceuLofjt/

Else to show the id_tipo and id_marca want show the name.

So, I don't know if I can show the tipo and marca name on the databtale declared on the index.blade or on the Ajaxcontroller.

Can someone help me please, any help will be apreciated.
