Ouch, I hate the high-speed, palm-forehead interface... esp. in
public! LOL
Not sure why this didn't occur to me earlier, but I found a solution
to what I am looking for (I'm still curious to know if there is an
easier way, always like to go with the flow when possible).
In short, the related classes are, well, short of the Manager class.
Here's a cheesy example:
class CustomNotes( models.Model )
value = models.TextField()
modified = models.DateTimeField( auto_now = True )
...
# the generic-relation stuff
content_object = generic.GenericForeignKey()
content_type = models.ForeignKey( ContentType )
objects = models.Manager()
class ClassNeedingNotes( models.Model ):
index = models.IntegerField()
...
# the generic-relation stuff
notes = GenericRelation( CustomNotes )
I am fully aware that there are issues when trying to relate the
acquired list of objects back to their original class. The connections
mechanism is not the same, it's a GenericRelation after all.
My problem was, I needed to globally process what in this example is
the 'CustomNotes' class. There are a couple of other functional
reasons I wanted to be able to have direct access to the tables, but I
won't bore anyone here with it.
So, hopefully someone else will either say, 'yup, that's how', 'great,
what I needed' or, give me another reason to slap my forehead.
