  • Looks like you don't want to get an Dinucleotides object with SSRtype 'Motiff", but with the value of POST['Motiff']? It's a big assumption from my side, but can you try to change the `objects.get` statement into `obj1=Dinucleotides.objects.get(SSRtype=request.POST['Motiff'])` – JerkMan Sep 14 '22 at 08:56

first of all, pass data in function and then call query.
