Comment:
I'm getting a similar problem here. I tried to add a new `ForeignKey` to
my database without resetting all data. The relevant database-part is a
`Series`-model which was supposed to have a `representative` `ForeignKey`
which should point to a `Watch`-model. The `Watch`-model itself has
another `ForeignKey` referencing the `Series`-model to define which series
it is in. But after adding the new `representative` FK, I cannot display
my existing `Watch`-models in the admin (inspecting them with the shell
works, though). Adding does not work either.
The traceback when I want to display an existing `Watch` is:
{{{

When I try to add a new object I get this in turn:
{{{

My system is
* Django from SVN, currently revision [4458] (updated today)
* Debian Sarge 3.1
* LigHTTPd 1.4.11-2bpo1
* PostgreSQL 7.4.7-6sarge3
* Python 2.5-2~bpo.1 (actually, I built this myself and added a bpo
suffix)
* python2.5-psycopg 1.1.21-3~bpo.1 (this was taken from Ubuntu and
modified for Debian)
But I can say that this is most certainly some issue with Django and not
something related with my setup which works rather good.
