Trouble getting a Django Form to render-CodePudding

Wondered if someone could help me with what I am doing wrong.

I wish to present an order form in Django where a customer will only ever fill in an order, they will never need to retrieve an existing order. So I think I only need a POST method and no GET method.

When I try to render a url with a form, I get a 405 response.

In my views.py file where I think I am making a mistake I have:

class RequestReport(View):
    def post(self, request, *args, **kwargs):
        form = CustomerOrderForm(data=request.POST)

        if form.is_valid():
            form.save()

        return render(
            "order.html",
            {
                "form": CustomerOrderForm()
            }
        )

And in my app urls file I have:

urlpatterns = [
    path('', views.RequestHome.as_view(), name='home'),
    path('order', views.RequestReport.as_view(), name='order'),
    path('blog', views.RequestBlog.as_view(), name='blog'),
    path('<slug:slug>/', views.PostDetail.as_view(), name='post-detail'),
]

And finally in my order.html file I have:

<form action="" method="post">
    {%  csrf_token %}

    {{ form.as_p }}

    <input type="submit" value="Submit" >
</form>

I know that the Customer Order Form is fine because if I insert this in my view it renders correctly

class RequestReport(CreateView):
    form_class = CustomerOrderForm
    template_name = 'order.html'
    success_url = "about"

But I want to be able to post the form.

CodePudding user response：

You still need to reach the form i.e. to "go" to the url where this form is without submitting it so that would be the get request

CodePudding user response：

405 is a Method Not Allowed error. Since you are making a get request when you go to /order, and your view hasn't implemented a get method, it results in a 405 error.

class RequestReport(View):
    def post(self, request, *args, **kwargs):
        form = CustomerOrderForm(data=request.POST)

        if form.is_valid():
            form.save()

        return redirect("somewhere else")

    def get(self, request, *args, **kwargs):
        return render(
            request,
            "order.html",
            {
                "form": CustomerOrderForm()
            }
        )
