I have a quiz form and when I want to save the answer the model does not store its question. I want to validate the form and save it when if form.is_valid (): I remove it and instead of AnswerForm I use the direct Answer model then it saves but not so. How to change it so that I can validate it and save it with the help of the form?
my code ->
models.py
from django.db import models
# Create your models here.
from django.core.exceptions import ValidationError
class Question(models.Model):
question=models.CharField(max_length=100)
answer_question=models.CharField(max_length=100, default=None)
def __str__(self):
return self.question
class Answer(models.Model):
questin=models.ForeignKey(Question, on_delete=models.CASCADE, related_name="questions")
answer=models.CharField(max_length=100,blank=True)
def __str__(self):
return str(self.questin)
forms.py
from django import forms
from django.contrib.auth.models import User
from django.core.exceptions import ValidationError
from django.forms import ModelForm
from .models import Question,Answer
class QuestionForm(forms.ModelForm):
class Meta:
model=Question
fields="__all__"
class AnswerForm(forms.ModelForm):
class Meta:
model=Answer
fields="__all__"
views.py
from django.shortcuts import render
from django.shortcuts import render, HttpResponse
from django.http import HttpResponseRedirect
from django.shortcuts import redirect
from .forms import QuestionForm,AnswerForm
from .models import Question,Answer
import random
from django.forms import modelformset_factory
def home(request):
form=QuestionForm
if request.method=='POST':
form=QuestionForm(request.POST)
if form.is_valid():
form.save()
return render(request, "question/base.html", {"form":form})
def ans(request):
questions=Question.objects.all()
form=AnswerForm()
if request.method=="POST":
if form.is_valid():
qu=request.POST["i_id"]
question_id=int(qu)
answ=AnswerForm(questin=question_id,answer=request.POST["answer"])
answ.save()
return render(request, "question/ans.html", {"form":form, "questions":questions})
ans.html
<!DOCTYPE html>
<html>
<head>
<title>question</title>
</head>
<body>
{% for i in questions %}
<form method="POST" required>
{% csrf_token %}
{{i}}
<input type="hidden" name="i_id" value="{{ i.id }}"/>
{% for a in form.answer %}
{{a}}
{% endfor %}
<input type="submit" name="sub">
</form>
{% endfor %}
</body>
</html>
