168	history() in django/views/admin/main.py makes assumptions about the object's key name	clintecker@…	Adrian Holovaty	"Normally the ID of an object is ""id"", except in cases like mine where I'd redefined the key to be something like list:

{{{ ""meta.AutoField('item_id','Item ID',primary_key=True,unique=True),"" }}}

When pulling up the history of a record in the administrative interface, the function history() in django/views/admin/main.py is called and an assumption is made on line 1080:

{{{ ""obj = mod.get_object(id__exact=object_id)"" }}}

In my case, I believe that it should be (it cannot be hardcoded like this, obviously this needs to be dynamic):

{{{ ""obj = mod.get_object(item_id__exact=object_id)"" }}}

Here's the exact text of the traceback I get:
