1.models's name userrecord.
2.below code of view.

@login_required def data(request, page, keyword,strencode):     current_username = request.user.username     data_s = dosomething() #it takes long time!!!     userrecord.objects.get_or_create(user=user.objects.get(username=current_username),myrecords=keyword) # in order create unique value     # or use below method     # if not userrecord.objects.filter(user=user.objects.get(username=current_username),myrecords=keyword):         # userrecord.objects.create(user=user.objects.get(username=current_username),myrecords=keyword)     return jsonresponse(data_s, safe=false)

requested below url several times no interval,something concurrent threading .
http://127.0.0.1:8000/data/1/test/english/
after operation done,myrecords column populated duplicate values.
found in django document use 'with transaction.atomic' deal problem did not work.

you don't need user user.objects.get(user=user.objects.get(username=current_username)) instead use request.user same.

@login_required def data(request, page, keyword,strencode):     current_user = request.user     data_s = dosomething()      userrecord.objects.get_or_create(user=current_user,myrecords=keyword) # in order create unique value     return jsonresponse(data_s, safe=false)

and myrecords=keyword create new record every time new keyword passed in def data view, please review code.
