            Q(title__icontains=query) |
            Q(category__icontains=query)
        )
     context = {'list_of_question':list_of_question}
    return render(request, 'index.html', context)

def viewQuestion(request, pk):
    my_list = get_object_or_404(Question, id=pk)
    list_of_question = Question.objects.get(id=pk)
    answers = Answer.objects.filter(post_id=list_of_question)

my models

    user = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=100, blank=False, null=False)
    body = models.TextField(blank=False, null=False) 
    category = models.CharField(max_length=50, blank=False, null=False)

    def __str__(self):
        return str(self.user)

class Answer(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    answer = models.TextField(blank=False, null=False)
    post = models.ForeignKey(Question, on_delete=models.CASCADE)

    def __str__(self):
        return str(self.user)

CodePudding user response：

In template viewQuestion you are using question variable

For example

{{question.title}},

but you are not passing it in context in viewQuestion view. There is only list_of_question, answers and my_list.

Replace list_of_question key with question and it should work:

def viewQuestion(request, pk):
    my_list = get_object_or_404(Question, id=pk)
    question = Question.objects.get(id=pk)
    answers = Answer.objects.filter(post_id=list_of_question)
    
    context = {'question':question, 'answers':answers, 'my_list':my_list}

    return render(request, 'viewQuestion.html', context)
