While Jani's admonishments might be considered 'best practice' in some
cases. Those do not always cover everyone's use case.
I solved a similar issue allowing users with the superuser role to have
edit access to some items that other staff do not have access to edit.
Use the get_form method of the ModelAdmin and select the form to call.
For example:
def get_form(self, request, obj=None, **kwargs):
if request.user.is_superuser:
kwargs['form'] = DMAdminSUForm
else:
kwargs['form'] = DMAdminForm
Then in each form you can set the readonly attributes and any other user
role specific functionality you need.
HTH,
