I get same error as before; 'NoneType' object has no attribute 'readiness'
when I changed to your excample. I don't understand why this is not working
for me, but for everyone else
Is it something I have forgot to import? I hope you can take a quick look
at my uploaded files. Is it ok to ju
try this get_form:
def get_form(self, request, obj=None, **kwargs):
if obj.readiness:
self.exclude = ("readinessDescription", )
return super(RequestForChangeAdmin, self).get_form(request, obj, **kwargs)
I have never used 'exclude' but it looks like yours should work.

What do you mean by tri-state?
You are using a field that allows three states: TRUE, FALSE and NULL.
If I understand the model, readiness would either be TRUE or FALSE. But if
you do not want to change your field type to:
readiness = models.BooleanField("Readiness", blank=True)
then try changin
and one more thing. My obj is always none (empty), why is that?

form = super(RequestForChangeAdmin,
self).get_form(request, obj, **kwargs)

Is 'readiness' really a tri-state flag?
Anyway you may want to test if obj.readiness exists, and is TRUE.
if obj.readiness and obj.readiness == TRUE:
