Problem with formset

[Satinderpal Singh]

I use formset in my views.py file for the forms. It saves the entries from the form to the database but the problem is that it shows all the previous forms along with the new form for the new entry. The code for my views file is given below:

def chemical_analysis(request):

ChemicalFormSet = modelformset_factory(chem_analysis)

if request.method=='POST':

                formset = ChemicalFormSet(request.POST, request.FILES)

                if formset.is_valid():

cd = formset.cleaned_data  

formset.save()

return HttpResponseRedirect(reverse('Automation.report.views.result_chem'))

else:

        return HttpResponse("There was an error with your submission. Please try again.")

else:

formset = ChemicalFormSet()

return render_to_response('report/report_add_row.html', {'formset': formset}, context_instance=RequestContext(request))

Any help will be appreciated.

Should that be cd.save()? Where else is cd used?

No other cd is used in this view, and i did not get your above logic, cd.save()

I think you are saying you don't understand my response? I'm asking if the problem is fixed by replacing formset.save() - with cd.save(), since you have cd = formset.cleaned_data but no other instances of cd, making it kinda useless?

should here be a cd = ObjectName() in there?

According to me, he need not to assign cd, because it is then not used
anywhere to clean the form data.

I tried this way, but it do not solve the problem.  

should here be a cd = ObjectName() in there?

If that is the case, how cd can save the data. But the problem is not with saving the entries but to clear the previous form entries.

Ok, I admit that I saw the cd and stopped thinking straight - apologies.

I don't know why you are getting the problem you are getting, but I would suggest that you should delete one indentation one the render_to_response line, so that it catches *everything* that falls through the cracks.

Also, we will probably need to see the view 'Automation.report.views.result_chem' since this view seems to be fine - and it's after a save that the issues start, correct?

cheers
