Re: add marks of same roll number of different of different semestrs

I will presume that you have 2 Student details with the same roll_no
but with different class numbers. If that is not the case, then you
will need to revisit the modelling of your data.

Anyway, something like this would work.

student_details = StudentDetail.objects.get(roll_no=<number>)


for student_detail in student_details:
<etc>

Does that make sense? This would work in the shell, but for a
template, you would need a view for the first bit, and the second in
the template.

cheers

When you used to be punk, and now you are still punk but not as punk,
are you post-punk or decaying punk or ex-punk or just not punk anymore
