Using multiple forms in one CBV?

Question

Django

I am currently using this code:

Spoiler

class ProductPage(TemplateView):
    category_form_class = CategoryForm
    product_form_class = ProductForm

    template_name = 'personal_area/pages/products.html'

    def post(self, request):
        post_data = request.POST or None
        profile_id = request.user.id

        category_form = self.category_form_class(post_data, profile_id=profile_id, prefix='category')
        product_form = self.product_form_class(post_data, prefix='product')

        product_form.fields['category'].choices = user_category(request.user.id)

        context = self.get_context_data(
            category_form=category_form,
            product_form=product_form,

            product_list=Product.objects.filter(profile_id=request.user.id),
            category_list=Category.objects.filter(profile_id=request.user.id)
        )

        if category_form.is_valid():
            self.form_save(form=category_form, profile_id=profile_id)
        if product_form.is_valid():
            self.form_save(form=product_form, profile_id=profile_id)

        return self.render_to_response(context)

    @staticmethod
    def form_save(form, profile_id):
        form_commit = form.save(commit=False)
        form_commit.profile_id = profile_id
        form_commit.save()
        return form_commit

    def get(self, request, *args, **kwargs):
        return self.post(request)

He works. However, after submitting one of the forms, form.errors fires on the other form and displays errors "name Required field." and so on for all required fields.
How can you fight it?

Answer 1

How can you fight it?

do not do this
1. why form_save is made staticmethod, it’s more like you don’t understand why
2. usually one form is one view
3. there is a FormView to work with forms and if you want several, but at one moment you process one form, don’t use form_class, otherwise we override the get_form_class or get_form method
