It seems like one way or another I always need to get access to a specific field of a Model object. The current way to do this is to iterate through the object's _meta.fields list, comparing with the name attribute. Why not just have a lookup of fields? If you paste this code at the bottom of your models.py file it will add a field_map attribute to the meta options.
For example:
`profile = User.objects.get(id=1).get_profile()`
`upload_to = profile._meta.field_map['image_icon'].upload_to`
...

import models as this_db
for item in dir(this_db):
try:
obj = getattr(this_db, item)
if type(obj) == models.base.ModelBase:
fields = dict((f.name, f) for f in obj._meta.fields)
setattr(obj._meta, 'field_map', fields)

Or you could just use
_meta.get_field("name"), which has been available since Django's initial public release.#
