Yea, usually we need data that uses subqueries like group by, having, ... and others, you must implement this methods by your own. But, by experience, its a disgusting work make CRUD methods for every model and implement the relationship navigation and its a in most cases its an iterative work implement CRUD forms. Every think that its iterative can be automated. I do the basic thinks. If you don't like you can overwrite the methods. The only think I don't know now how to implement it's the selfrelationships.
