Django

Question

谁能告诉我如何将细节视图与列表视图结合起来并在同一个模板中显示信息，我会向您解释，我正在学习 Django，我正在尝试创建一个问答网络应用程序，我需要为了用它的所有 awnsers 显示问题，我需要在我的详细视图中显示一个特定的问题，在所有 awsers 下方显示，比如 Whosebug

#models.py
from django.db import models
from django.conf import settings
from django.contrib.auth.models import User


# Create your models here.
class Question(models.Model):

    # user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="question", null=True)
    name = models.CharField(max_length=100)
    description = models.TextField(max_length=100)
    date = models.DateTimeField(auto_now_add=True)
    cant_resp = models.IntegerField(default=0)
    question_type = models.CharField(max_length=50, choices=QUESTION_TYPES_CHOICES)

    def __str__(self):
        return self.description




class Anwser(models.Model):

    # user = models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE)
    user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="anwser", null=True)
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    text = models.TextField(max_length=400)
    date= models.DateTimeField(auto_now_add=True)

#and this are my views.py
from django.shortcuts import render, redirect
from django.urls import reverse, reverse_lazy
from django.contrib.auth.mixins import  LoginRequiredMixin
from django.views import generic

from .forms import QuestionForm, AnwserForm
from .models import Question

# Create your views here.

class QuestionListView(LoginRequiredMixin, generic.ListView):
    template_name = 'anwserquestions/question_list.html'
    context_object_name = 'questions'

    def get_queryset(self):

        return Question.objects.all()

def createquestion(response):
    if response.method == "POST":
        print("Its POST method")
        form = QuestionForm(response.POST)
        # user =response.user
        if form.is_valid():
            name = form.cleaned_data["name"]
            description=form.cleaned_data['description'],
            question_type=form.cleaned_data['question_type'],
            # date=form.cleaned_data['date'],
            t = Question(name=name, description=description, question_type=question_type, cant_resp=0)
            t.save()
            response.user.question.add(t)  # adds the to do list to the current logged in user

            # return HttpResponseRedirect("/%i" %t.id)
            return redirect('anwserquestions:question-list')

    else:
        form = QuestionForm()

    return render(response, "anwserquestions/question_create.html", {"form":form})

    
class QuestionDetailView(LoginRequiredMixin, generic.DetailView):
    model = Question
    template_name = 'anwserquestions/question_detail.html'
    context_object_name = 'question'

    def get_queryset(self):
        return Question.objects.all()


class QuestionDeleteView(LoginRequiredMixin, generic.DeleteView):
    template_name = 'anwserquestions/question_delete.html'
    context_object_name = 'question'
    success_url = reverse_lazy('anwserquestions:question-delete')

    # def get_queryset(self):

    #     return Question.objects.all()

Answer 1

您可以将相关的 answers 包含在视图上下文中，这样您 QuestionDetailView 就变成了

class QuestionDetailView(LoginRequiredMixin, generic.DetailView):
    model = Question
    template_name = 'anwserquestions/question_detail.html'
    context_object_name = 'question'

    def get_context_data(self, **kwargs):
        context = super(QuestionDetailView, self).get_context_data(**kwargs)
        context['answers'] = Answer.objects.filter(post=self.get_object())
        return context
