If *.erb files don't connect  to the database in the entire context of
the application (which they do through models which does it through
other stuff) then you are wrong too, because models don't connect to
the database, they go through other stuff (like your view does) and
model out the behavior.

No, you are wrong.  The model xyz.rb has direct access (through inheritance) to the database table xyzs.  Thus, the method:

def Xyx.get_first
  find(1)
end

returns the row of table xyzs with id=1 with no qualification.  In a controller, the statement find(1) is meaningless.  You have to reference the model to get access to the table as in Xyz.find(1).  Views (*.erb files) should never directly reference models.  They get their database information from the controller.
