How to create a pdf output file in a chosen directory with Hardcopy in Django?

I would like to automatically save the result in a pdf file in a chosen directory. I use the django-hardcopy module. Currently, I can display the pdf with a url. Thank you for your ideas.

Here is the view:

from django.conf import settings
from hardcopy.views import PDFViewMixin, PNGViewMixin

class pdf_hardcopy(PDFViewMixin, TemplateView):
    download_attachment = True
    template_name = 'project/pdf_hardcopy.html'

    def get_filename(self):
        return "my_file.pdf"

    def get_context_data(self, *args, **kwargs):
        context = super(pdf_hardcopy, self).get_context_data(*args, **kwargs)
        id = self.kwargs['pk']
        dossier_media = str(settings.MEDIA_ROOT)
        GetDataTeam = Datas.objects.filter(id=id)
        context["GetDataTeam"] = GetDataTeam
        return context

My url:

path('pdf_hardcopy/<int:pk>/', views.pdf_hardcopy.as_view(), name='pdf_hardcopy'),

Taking a quick look at the repo, it doesn't look like there's any built-in way to do this. I would probably override PDFViewMixin's get_file_response method. You can see the current implementation in the views.py file [github link].

You could do something like this in your views.py file:

class PDFViewAndSaveMixin(PDFViewMixin):
    """Override PDFViewMixin to also save file."""

    def get_file_response(self, content, output_file, extra_args):
        with open(f'save/location/{self.get_filename}', ‘w’) as local_file:
            local_file.write(output_file)
        return super().get_file_response(content, output_file, extra_args)


class pdf_hardcopy(PDFViewAndSaveMixin, TemplateView):
    # ...

This is a rather crude way of saving the file, and you probably should create a Django model with a FileField to manage these files, rather than simply writing them directly to disk. See the Django docs on managing files.
