I made a model form and a view which accepts input as a form and
display it in the html format. As when i refresh the html page or try
to fill another entry in the form, it gives the following error:
The view Automation.report.views.chemical_analysis didn't return an
HttpResponse object.
Here is the views that creates this problem:
def chemical_analysis(request):
if request.method=='POST':
form = chem_analysisForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
form.save()
chem = chem_analysis.objects.all()
#return HttpResponseRedirect(chem)
return render_to_response('report/chemical_analysis.html',
{'chem': chem,},context_instance=RequestContext(request))
else:
form = chem_analysisForm()
return render_to_response('report/report.html', {"form":form},
context_instance=RequestContext(request))
Any help regarding this will be highly appreciated.

Thanks, it works and now gives the error message, can you please tell
me that why the input values are not saved in the database and it
gives only the error message. Point me where i am wrong.

The form is not valid; check the data you are submitting and the form
definition to see why. The invalid form object itself will specify why
it is invalid, see the docs:
Its possible that when you refresh the form and the POST request gets
submitted, the form doesn't pass the form.is_valid() if conditional.
In your code, you didn't make any provision for when the form fails
the is_valid() test and from your code, execution stops once
is_valid() returns False so I **guess** that's where the problem lies.
Try re-rendering the submitted form if is_valid is False or doing a redirect.
