KeyError at /admin/newapp/profile/add/ and Search Error --- Related Field got invalid lookup: icontains

Hi

Here i want to exclude some model filed depending upon type of User.

Example if username is "dgp", i want to exclude

in admin.py

  if username == "dgp":
       self.exclude = ("UserNext","UserNextDate","UserNextDepartment","CaseStatus")

in

def get_form(self, request, obj=None, **kwargs):
  I do not use fieldset and comment the code, i get field excluded in "dgp" Login. Code execute successfully and fields get excluded.

But if i use filedset, I get the error

                    'fields': [ ('CaseAdvocate'),
                    ('CasePartyNames','CaseOppositePartyNames'),'CaseLastDate' ] } ),

                    ('Incharge Officer Information', {'classes':['collapse'],
                    'fields': [ ('UserNext','UserNextDate'),
                    ('UserNextDepartment','CaseStatus') ] } )
                 ]
  list_per_page = 5    


  def get_form(self, request, obj=None, **kwargs):

    username = request.user.username   
    print (username)
   
    if username == "dgp":
       self.exclude = ("UserNext","UserNextDate","UserNextDepartment","CaseStatus")
       # self.exclude = ("location","birth_date","bio", )
       form = super(ProfileAdmin, self).get_form(request, obj, **kwargs)
       return form
    else:
       form = super(ProfileAdmin, self).get_form(request, obj, **kwargs)
       return form

Can anybody help me in this regards.

If i comment Fieldset, than code works in "dgp" login with hiding necessary fields.

Also my search is not working
