Django 表单未显示在模板上

Question

I am trying to show two forms ( UserRegisterForm and TeacherRegisterForm ) in one template. But, only the UserRegisterForm is showing up in the rendered HTML.

teacher-register.html

<form enctype="multipart/form-data"  action="" method="post">
  {% csrf_token %}
  {% crispy user_form %}
  {% crispy teacher_form %}
  <div class="form-group mt-3">
    <button class="btn btn-outline-info" type="submit">Sign Up</button>
  </div>
</form>

urls.py

urlpatterns = [
    path('login/', LoginView.as_view(template_name='accounts/login.html'), name='login'),
    path('register/', register, name='register'),
    path('TeacherRegister/', register_teacher, name='teacher-register'),
    path('logout/', sign_out, name='logout'),
    path('profile/', sign_out, name='logout'),
]

views.py

def register_teacher(request):
    if request.user.is_authenticated:
        return redirect('dashboard')

    if request.method == 'POST':
        user_form = UserRegisterForm(request.POST)
        teacher_form = TeacherRegisterForm(request.POST,
                                           request.FILES)
        if user_form.is_valid() and teacher_form.is_valid():
            user = user_form.save(commit=False)
            user.is_student = False
            user.is_teacher = True
            user.save()
            profile = teacher_form.save(commit=False)
            profile.user = user
            profile.save()
            messages.success(
                request, f'Your account has been created!')
            return redirect('login')

    else:
        user_form = UserRegisterForm()
        teacher_form = TeacherRegisterForm()

    context = {
        'user_form': user_form,
        'teacher_form': teacher_form,
    }

    return render(request, 'accounts/teacher-register.html', context)

    birth_date = forms.DateField(

        widget=forms.widgets.DateInput(attrs={'type': 'date'}),
    )
    facebook = forms.URLField(

    )

    class Meta:

        fields = [
            'image',

        self.helper = FormHelper()
        self.helper.form_tag = False
        self.helper.layout = Layout(
            Div(
                Div('image', css_class="col-sm-6"),
                Div('birth_date', css_class="col-sm-6"),
                css_class='row',
            ),
            FloatingField('facebook'),
        )

    def __str__(self):
        return f'{self.user.first_name} {self.user.last_name}'

I did the same thing for student-register.html template and it's working fine. I've searched for hours but couldn't find any bug in my code.

EDIT:

In views.py , if I set teacher_form = StudentRegisterForm() , the StudentRegisterForm appears in the teacher-register.html template. So, I guess the problem might be somewhere in the class TeacherRegisterForm()

Answer 1

I somehow had this code way below in my forms.py file:

class TeacherRegisterForm(forms.ModelForm):
    class Meta:
        model = Teacher
        fields = []

I have no idea where it came from. It was overriding my main TeacherRegisterForm() class, which is why no fields were appearing in the template.

Removing it solved the problem.
