我想在 (views.py) 中 运行 我的 else 语句但是当服务器是 运行 它会自动转到 if 语句吗？

Question

#views.py class 添加问题（查看）：

def post(self, request):
    forms = QuestionForm(request.POST)
    if forms.is_valid:
        forms.save()
        print("If statement")
        return redirect(reverse('home'))
    else:
        print("else statement")
        return render(request,'file/addQuestion.html')
   

def get(self, request):
    forms = QuestionForm()
    context = {'forms': forms}
    return render(request,'file/addQuestion.html',context)

#forms.py 从 django.forms 导入 ModelForm from .models import 问题 来自 django.core.exceptions 导入 ValidationError

class 问题表（模型表）：

class Meta:
    model = Question
    fields = "__all__"

    

def clean_answer(self):
    answer = self.cleaned_data['answer']
    option1 = self.cleaned_data['option1']
    option2 = self.cleaned_data['option2']
    option3 = self.cleaned_data['option3']
    option4 = self.cleaned_data['option4']
    if answer == option1 or answer == option2 or answer == option3 or answer == option4:
        return answer
    else: 
        raise ValidationError("Select an answer from the options.")

Answer 1

使用forms.is_valid():代替forms.is_valid:

def post(self, request):
    forms = QuestionForm(request.POST)
    if forms.is_valid():
        forms.save()
        print("If statement")
        return redirect(reverse('home'))
    else:
        print("else statement")
        return render(request,'file/addQuestion.html')
