How to restore Models original Properties - Problem in Models column Exclude

Hi

i have encountered very strange problem.  have two user . One is superuser of name "root" and another is general user of name "dgp". I have model of Name Profile with 21 fields around.

I want to show all field of Model Profile in "root" login.

I want to exclude 4 field of Model Profile in "dgp" login.

I get correct output If i do login in this sequence root - dgp

I get wrong output If i do login in this sequence  dgp - root

( Means I get 4 field excluded in root Login also. )

Means once i do login using "dgp" user , i always get all 4 fields excluded in subsequent login for any user unless and until i restart the server.

I have a model of name Profile and I want to exclude four fields for user of name  "dgp" .

Fields are

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

I have superuser as root.

1.  When I run the code and do the login using root user login

I get all Fields of Profile Model.

2 I do logout and Login Using "dgp" user. I get all Fields of Profile Model except

the four fields.      'UserNext','UserNextDate','UserNextDepartment','CaseStatus', )

Here My code Execute successfully.

But when I change the sequence of Login, Code shows the

all Fields of Profile Model except

the four fields in both login "dgp" as well as "root".

I have overridden Models Two methods. Necessary Model and admin code is shown below.

Please help n this regards.
