Question

请向我解释如何匹配django中特定问题的答案。现在，我面临的问题是，如果用户在Answer数据库中退出，则无论用户在表单中输入的内容均返回True，但是我想要的是，用户输入的内容应与该特定问题的Answer匹配，而不是任何存在的答案。

models.py

from django.db import models
from django.contrib.auth import get_user_model
from PIL import Image
User=get_user_model()
# Create your models here.
class Question(models.Model):
    question_name=models.CharField(max_length=20,unique=True,default=' ')
    question_image=models.ImageField(upload_to='levels/')
    question_text=models.TextField(blank=True,max_length=100)

    def __str__(self):
        return str(self.question_name)
    class Meta:
        ordering= ["question_name"]

class Answer(models.Model):
    question_relation=models.ForeignKey(Question,on_delete=models.CASCADE)
    answer=models.CharField(max_length=100,unique=True)

    def __str__(self):
        return self.answer

forms.py

from django import forms
from .models import Answer,Question
from django.core.exceptions import ObjectDoesNotExist
from . import views
class CheckAnswer(forms.Form):
    your_answer=forms.CharField(label='Answer')
    def clean(self):
        cleaned_data=super(CheckAnswer,self).clean()
        response=cleaned_data.get("your_answer")
        try:
            p = Answer.objects.get(answer__iexact=response)
        except Answer.DoesNotExist:
            raise forms.ValidationError("Wrong Answer.")

views.py

from django.shortcuts import render,redirect,get_object_or_404
from django.views.generic import *
from . import models
from django import forms
from .forms import CheckAnswer
from django.contrib.auth.decorators import login_required
from .models import Question
from dashboard.models import UserLoggedIn

# Create your views here.
@login_required
def Arena1(request):
    if request.method=='POST':
        form = CheckAnswer(request.POST)
        if form.is_valid():
            return redirect('thanks')
    else:
        form=CheckAnswer()
    args={'form':form}
    return render(request,'levels/arena1.html',args)

我认为将使用pk的概念，但我不知道如何实现请更新我的代码以解决此问题。

首先，匹配问题将要求您存储以某种方式向功能提供问题。您可以使用全局变量或容器来执行此操作，在呈现问题时可以在其中设置值，然后将其导入forms.py并设置your_question = Question

forms.py

from django import forms
from .models import Answer,Question
from django.core.exceptions import ObjectDoesNotExist
from . import views
class CheckAnswer(forms.Form):
    your_answer=forms.CharField(label='Answer')
    def clean(self):
        cleaned_data=super(CheckAnswer,self).clean()
        response=cleaned_data.get("your_answer")
        try:
            p = Answer.objects.get(answer__iexact=response)
            if(your_answer == p.answer and your_question == p.question_relation.question_text): #user inputs should be matched with the Answer of that particular Question
                #Code To Run for Correct Answer Goes Here
            else:
                #The Answer is Wrong or Does not Match the Particular Question
                raise forms.ValidationError("Wrong Answer.")
        except Answer.DoesNotExist:
            raise forms.ValidationError("Wrong Answer.")
