Is it possible to access values submitted through HTML Form, rendered in Preview page, in another views.py method

I am newbie in a django framework. And trying to print PDF from the submitted data through HTML form. For that I have 2 stages.

  1. Fillup the form
  2. Preview(result) those filled up data
  3. Generate PDF from the preview(result) page

I have managed to post data using HTML form.

My views.py

def preview(request):
    if request.method == "POST":
        formvals = Formdata()
        formvals.date = request.POST["date"]
        formvals.name = request.POST["name"]
    
        return render(request, "result.html", {'formvals':formvals})

def getpdfPage(request):
    formvals = preview(request)
    print(formvals.date)
    print(formvals.name)
    data = {'date':formvals.date, 'formvals.name'}
    template = get_template("pdf_page.html")
    data_print = template.render(data)
    response = BytesIO()
    pdfPage = pisa.pisaDocument(BytesIO(data_print.encode("UTF-8")),response)
    if not pdfPage.err:
        return HttpResponse(response.getvalue(),content_type="application/pdf")
    else:
        return HttpResponse("Error faced")

Urls.py

urlpatterns = [
    path('',views.home, name='home'),
    path('getpdfPage',views.getpdfPage, name='getpdfpage'),
    path('preview',views.preview, name='preview')
]

Here I get None values when i try to print data dict in getpdfPage()

Is there any way to access the data of preview() in getpdfPage().

Thanks in advance

You should not access formvals.date, formvals.name like this, but you should replace

        formvals = Formdata()
        formvals.date = request.POST["date"]
        formvals.name = request.POST["name"]

with

        formvals = Formdata()
        formvals.update({'date': request.POST["date"], 'name': request.POST["name"]}

What I would do is save the preview formdata into a model.

Once you have a model with the saved data that represents this form then you can access this model instance from any view by just doing a query, for example: YourModel.objects.filter(date=some_date) or YourModel.objects.filter(name=some_name)
