I am a Django developer and I am trying two put two forms in one html file(register and login forms), but when I write an invalid input into them, they didn’t return any error.
views.py

def log(request):
if request.method == 'POST':
    print(request.POST)
    if 'email' in request.POST:
        regisform = RegisterForms(request.POST)
        if regisform.is_valid():
            print("is valid")
            clean_data = regisform.cleaned_data
            user =User.objects.create_user(username=clean_data['user_name'],password=clean_data['password_2'],email=clean_data['email'])
            login(request,user)
            messages.success(request, "شما با موفقیت ثبت نام شدید." )
            Profile.objects.get(user_id = request.user.id).hearts_time = jdatetime.datetime.today()
            send_user_notification(user=user, payload={"head":"تبریک", "body":"به سایت ویکی ریاضی حوش آمدید."}, ttl=10)
            return redirect('home:homepage')
        else:
            print("is not valid.")
    else:

        form = LoginForms(request.POST)
        if form.is_valid():
            data = form.data
            print(data)
            print("running")
            try:
                user = authenticate(request, username = data['username'],password=data['password'])
                print(user)
            except:
                user =authenticate(request, email = data['email'],password=data['password'])
                print(user)
            if user is not None:
                login(request, user)
                messages.success(request, "شما با موفقیت وارد شدید.","warning")
            else:
                print('NOT LOGIN')
            return redirect('home:homepage')
    

else:
    print("Naderi")
    form = LoginForms()
    regisform = RegisterForms()
try:

    content = {
        'form':form,
        'regist':regisform,
    }
except:
    content = {
        'regist':regisform,
    }
return render(request, 'accounts/login.html',content)

forms.py

class RegisterForms(forms.Form):
user_name = forms.CharField(max_length=30, widget=forms.TextInput(attrs={"placeholder":'username'}))
password_1 = forms.CharField(max_length=30,widget=forms.PasswordInput(attrs={'placeholder':'password'}))
password_2 = forms.CharField(max_length=30,widget=forms.PasswordInput(attrs={'placeholder':'Confirm password'}))
email = forms.EmailField(widget=forms.EmailInput(attrs={'placeholder':'Email'}))
captcha = ReCaptchaField(widget=ReCaptchaV2Checkbox)
def clean_password_2(self):
    print('func 1 is begining.')
    password1 = self.cleaned_data['password_1']
    password2 = self.cleaned_data['password_2']
    listletter = 'abcdefghijklmnopqrstuvwxyz'
    listletterc = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
    adad = '1234567890'
    print(password1,password2)
    if password1 != password2:
        raise forms.ValidationError('the passwords are not equal.')
    elif len(password2)< 6:
        raise forms.ValidationError('Short Password.')
    small = 0
    cap = 0
    ada = 0
    for i in range(26):
        letter = listletter[i]
        capp = listletterc[i]
        if letter in password2:
            small += 1
        if capp in password2:
            cap += 1
    for i in range(10):
        num = adad[i]
        if num in password2:
            ada += 1
    if small == 0:
        raise forms.ValidationError('do not use the small letters.')
    if cap == 0:
        raise forms.ValidationError('do not use the capital letters.')
    if ada == 0:
        raise forms.ValidationError('do not use numbers.')
    
def clean_user_name(self):
    print('un')
    usern = self.cleaned_data['user_name']
    print(usern)
    if User.objects.filter(username = usern).exists():
        raise forms.ValidationError('Please choose another username.')

and login forms:

class LoginForms(forms.Form):
username = forms.CharField(max_length=30,widget=forms.TextInput(attrs={'class':'username','placeholder':'Username'}))
password = forms.CharField(max_length=30, widget=forms.PasswordInput(attrs={'class':'password','placeholder':'Password'}))
captcha = ReCaptchaField(widget=ReCaptchaV2Checkbox)
