        </form>

Answer 1

A GET request is used to retrieve the page, whereas a POST request is used to submit the form. Here you only construct a form in the POST request. For the GET request, you did not even define a context , which will thus raise an error.

from cheatexam_question.forms import QuestionForm

def newquestion(request):
    if request.method == 'POST':
        form = QuestionForm(request.POST)
        # …
    else:  # GET request
        form = 
    context = {
        'form': form
    }
    return render(request, 'homepage.html', context)

Answer 2

take the form before request.post like this:

def newquestion(request):
    form = QuestionForm(request.POST or None)
        if form.is_valid():
        .
        .
    context = {'form':form}
    retrun render(request , 'template.html' , context)

note: context and return is not in 'if' block
