I "have" to put the code in the table just in case I don't use the view; so I thought that if I inserted the newId() in the view I would end up creating twice the PK (and wasting PK), but I tested and it was not the case. So I don't really know what should I do from a "good practices" point of view.

Javier,
Personal suggestion: Both and mark key updatable. A newid() function returning GUID fit into this perfectly. Key would be 'at least' 16 bytes so a trade off there.
PS:SQL server NewID() function returns a GUID.
