How to validate the registered users with login in django?

问题

Here I am using a non custom user model for saving the users registered and their details are stored in user_requirement model now I want to validate before logging in to the dashboard My models.py:

class user(models.Model):
    username=models.CharField(max_length=20)
    email=models.CharField(max_length=50,unique=True)
    password=models.CharField(max_length=50,default='0000000')
    created_at = models.DateTimeField(default=datetime.now)
    updated_at = models.DateTimeField(default=datetime.now)

    def __str__(self):
        return self.username
class User_Requirement(models.Model):
    user=models.ForeignKey(user,on_delete=models.CASCADE)
    room = models.ForeignKey(room,on_delete=models.CASCADE)
    goal = models.ManyToManyField(goal)
    design = models.ManyToManyField(design)
    furniture = models.ForeignKey(furniture,on_delete=models.CASCADE)
    created_at = models.DateTimeField(default=datetime.now)
    updated_at = models.DateTimeField(default=datetime.now)

My forms.py:

class UserForm(forms.ModelForm):
    class Meta:
        model = user
        fields = ('username','email','password')

    def clean_email(self):
        # Get the email
        email = self.cleaned_data.get('email')
        # Check to see if any users already exist with this email as a username.
        try:
            match = User.objects.get(email=email)
        except User.DoesNotExist:
            # Unable to find a user, this is fine
            return email
            raise forms.ValidationError('This email address is already in use.')
class UserRequirementForm(forms.ModelForm):
    class Meta:
        model = User_Requirement
        fields=('room','goal','design','furniture')
        error_messages = {
            'room': {
                'required': "Please select any of the room in the first step",
            },
            'goal': {
                'required': "Please select any of the goals in the second step",
            },
            'design': {
                'required': "Please select any of the design in the forth step",
            },
            'furniture': {
                'required': "Please select any of the furniture in the third step",
            },
        }

My views.py:

def user_register(request):
    if request.method == 'POST': # if there is a post request in the form
        user_form = UserForm(data=request.POST) #first of all it is a user_form will be posted details present in the user_form
        user_requirement_form = UserRequirementForm(data=request.POST)# after posting the details of the user_form post the details
        if user_form.is_valid() and user_requirement_form.is_valid(): # if user_form & user_requirement form is valid
            user = user_form.save()#if form is valid save
            user_requirement = user_requirement_form.save(commit=False)
            # Set user
            user_requirement.user = user
            user_requirement.save()
            user_requirement_form.save_m2m()
            messages.success(request,('Project saved successfully'))

            return render(request,'home1.html')
        else:
            messages.warning(request, 'Please correct the errors above')
    else:  
        user_form = UserForm()
        user_requirement_form = UserRequirementForm()
    return render(request,'register.html', {'user_form': user_form, 'requirements_form': user_requirement_form})


    def login(request):
      if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']

        user = auth.authenticate(username=username, password=password)

        if user is not None:
          auth.login(request, user)
          messages.success(request, 'You are now logged in')
          return redirect('dashboard')
        else:
          messages.error(request, 'Invalid credentials')
          return render(request,'login.html')
      else:
        return render(request, 'login.html')

Here registration is being done perfectly but the registered users should be able login right but the view which I wrote is not validating please see and say If I did any wrong
