In Django I use request.POST and return JSONResponse but the url shows HttpResponse object error. I-CodePudding

I'm using Ajax to submit a POST. In views.py I have the following:

def color(request):
    if(request.POST.get('mydata',False)):
        mylist= request.POST['mydata']
        mylist= mylist.split(",")
        request.session['var1'] = mylist[0]
        request.session['var2'] = mylist[1]
        return JsonResponse({'success':True})

In urls.py I defined color, so when I go to localhost:8000/color it shows error: "didn't return an HttpResponse object". I should use instead return render(request,'app/color.html',{}) but I do not have a color.html file. I actually don't want to have one. All I want is to post a variable and use it as a session, so how can I avoid using render() and creating the html file? Thanks

CodePudding user response：

Is that all the code of your view? If so then the error is because you aren't returning anything if your request.POST.get('mydata',False) if-statement returns False. You need a final return, like this:

def color(request):
    if(request.POST.get('mydata',False)):
        mylist= request.POST['mydata']
        mylist= mylist.split(",")
        request.session['var1'] = mylist[0]
        request.session['var2'] = mylist[1]
        return JsonResponse({'success':True})
    return JsonResponse({'success':False}) # a response is now always returned
