Issues with two forms submission in django one after another - django

Question

I'm working on forget password page in which the user first have to answer the question for enabling the textfields for creating new password.
Here, I have two forms, One for security question and second for password and confirm password.
Following is my forms.py
from django import forms
from .models import SecurityQuestions
class PasswordForm(forms.Form):
password = forms.CharField(disabled=True, widget=forms.PasswordInput(attrs={'placeholder':'New Password'}))
password_confirm = forms.CharField(disabled=True, widget=forms.PasswordInput(attrs={'placeholder':'Re-enter Password'}))
def clean(self, *args,**kwargs):
password = self.cleaned_data.get('password')
password_confirm = self.cleaned_data.get('password_confirm')
if password and password_confirm:
if password != password_confirm:
raise forms.ValidationError('Password Mismatch')
return super(PasswordForm, self).clean(*args, **kwargs)
class PasswordVerificationForm(forms.Form):
question = forms.ModelChoiceField(queryset=SecurityQuestions.objects.all(), empty_label=None, widget=forms.Select(attrs={'class':'form-control','id': 'sectxt'}))
answer = forms.CharField(label='answer', widget=forms.TextInput(attrs={'placeholder':'Answer','id': 'anstxt'}))
Following is my views.py
from django.shortcuts import render, redirect
from .forms import PasswordForm, PasswordVerificationForm
from django.contrib.auth.decorators import login_required
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth.hashers import make_password
from .models import SecurityQuestions
from django.contrib import messages
#login_required
#csrf_exempt
def password_reset(request):
form = PasswordForm(request.POST or None)
form1 = PasswordVerificationForm(request.POST or None)
if request.method == 'POST':
if request.POST.get("verify", False):
question = request.POST.get('question')
answer = request.POST.get('answer')
print("question",question)
print("answer",answer)
check = SecurityQuestions.objects.get(id=question) #id=1
print(check.answer)
if check.answer == answer:
messages.success(request, 'Enter Your New Password', 'alert-success')
form.fields['password'].disabled = False
form.fields['password_confirm'].disabled = False
else:
redirect('/')
messages.error(request, 'Incorrect Answer', 'alert-danger')
if request.POST.get("create", False):
if form.is_valid():
print("For Changing Password...")
password = form.cleaned_data.get('password')
request.user.password = make_password(password)
request.user.save()
return redirect('/')
else:
form = PasswordForm()
form1 = PasswordVerificationForm()
return render(request,"forget_password.html", {"form": form, "form1":form1})
Following is my forget_password.html

</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
</div>
If I enter the security answer first, based on the condition, if true, it enables the textfields for password and password_confirm.
But it's not creating the new password.
However, if I change the disabled = False in PasswordForm then it creating the new password successfully.
I want to know why it's not executing the code after the first form executes successfully.
Thanks!

You really should chain this into 2 urls, rather then trying 2 forms in one page. You can only submit one form and this is the problem you're facing. Once you have submitted the security question, you instantiate the form again with fields disabled:
form = PasswordForm(request.POST or None)
And now they do not get enabled, because the submit button called 'verify' from form1 is no longer present, so the code in that branch is not executed.
Let's say url is /password_reset/ - a rough outline (untested):
#login_required
#csrf_exempt
def security_question(request):
form = PasswordVerificationForm(request.POST)
if request.method == 'POST':
if form.is_valid():
token = generate_strong_token() # Implement: generate a strong token, url safe
request.session["password_reset_token"] = token
return redirect(f'/password_reset/{token}/')
else:
return render(...)
#login_required
#csrf_exempt
def change_password(request, **kwargs):
form = PasswordForm(request.POST)
token = request.session.get('password_reset_token')
if token == kwargs['token']:
if request.method == 'POST' and form.is_valid():
del request.session['password_reset_token']
# handle password change and redirect to wherever
else:
return render(...)
else:
raise SecurityError('Invalid token')
Your urls would be something like:
urlpatterns = [
re_path('password_reset/(?P<token>[0-9A-F]{32})/', change_password)
path('password_reset/', security_question)
]
