Re: Export HTML template filled by form to HTML file

If I haven't misunderstood, you wish to add/update/list data to/from the DB via a form?  I am learning myself and I have just successfully  managed to achieve this through CBV's (Class Based Views), which obviate the use of forms and perform well – with fewer lines of code. In Django 2.2.x the views.py file contains the following import:

from django.views.generic import (

    TemplateView,

    View, ListView, DetailView, CreateView, UpdateView, DeleteView)

 

One of my models is called Organisation inside the application – pbs1/.  The views.py file contains the following classes:

class Org_View(ListView):

    model = Organisation

    # Returns organisation_list

 

class Org_DetailView(DetailView):

    context_object_name = "org_detail"

    model = Organisation

    template_name = 'pbs1/organisation_detail.html'

    # Returns organisation

 

class OrgCreateView(CreateView):

    fields = ('org_Name', 'org_Site', 'org_HQ_Location', 'org_Sector',

              'currency_Code', 'org_Parent', 'org_Turnover', 'org_Multi_National', 'spec_Name')

    model = Organisation

 

class OrgUpdateView(UpdateView):

    fields = ('org_Name', 'org_Site', 'org_HQ_Location', 'org_Sector',

              'currency_Code', 'org_Parent', 'org_Turnover', 'org_Multi_National', 'spec_Name')

    model=Organisation

 

class OrgDeleteView(DeleteView):

    model = Organisation

    success_url = reverse_lazy("pbs1:organisation_list")

 

Each class does exactly what it says – e.g. OrgUpdateView allows me to update a previously created record in the DB.  The urls.py and *.html are a bit more complicated.  But, I can share these with you as well.  I learnt/am learning this stuff through Python and Django Full Stack Web Developer Bootcamp from Udemy.

Subject: Export HTML template filled by form to HTML file

 

I have a template page on which one I access when I filled my `Django form`. This page is a simple `HTML page` with data coming from my form. I would like to be able to download the filled template. That's to say, get a browser window which let to download the template or by clicking on a button which will save the HTML template somewhere.

 

This is my code in my **views.py** file:

 

   

 class TemplateGenerator(TemplateView):
        ''' This class displays the form and lets to save data into my database.
            It redirects users to the filled HTML template '''
        form_class = CommunicationForm
        template_name = 'form.html'
        success_url = '/HTML_Result/'
   
        def get(self, request):
            form = self.form_class()
            return render(request, self.template_name, {'form': form})
   
        def post(self, request):
            form = self.form_class(request.POST, request.FILES)
            if form.is_valid():
                form.save()
                return redirect('HTML_Result')
            args = {'form': form}
            return render(request, self.template_name, args)
   
   
class HTMLResult(TemplateView):
      ''' This class displays the template filled thanks to the form from TemplateGenerator() class '''
      template_name = 'template_1.html'
   
      def get(self, request):
          data = Communication.objects.values().latest('id')
          self.donwload_html()
          return render(request, self.template_name, {'data': data})
   
      def donwload_html(self):
          file_path = os.path.join(settings.MEDIA_ROOT, 'media')
          if os.path.exists(file_path):
              with open(file_path, 'rb') as fh:
                  response = HttpResponse(fh.read(),
                                            content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
                  response['Content-Disposition'] = 'inline; filename=' + 'test'
                  return response
          raise Http404

 

 

I know I need to use `Content-Disposition` in order to download the HTML page, but I don't find a way to use it correctly.
Do you have any idea ?

 

Thank you by advance
