PDF not saving on Django using open()

[George Rogers]

trying to save files on static after pdfcrowd provides the file. I've tried adding the path to be specific it doesn't work.

from PyPDF2 import PdfFileMerger, PdfFileReader
from django.template import RequestContext
from django.shortcuts import render_to_response, get_object_or_404

import pdfcrowd
from django.http import HttpResponse
from wildling.models import *
from django.shortcuts import redirect

def home(request, template_name='brochures_form.html'):
    context = RequestContext(request)
    if request.method == 'POST':
        context['name'] = name = request.POST.get('name','')
        context['adults'] = adults = request.POST.get('adult','')
        context['children'] = children = request.POST.get('child','')
        context['infant'] = infant = request.POST.get('infant','')
        context['start_date'] = start_date = request.POST.get('start-date','')
        context['end_date'] = end_date = request.POST.get('end_date','')
        context['country'] = country = request.POST.get('country','')
        context['destination'] = destination = request.POST.get('destination','')
        context['price'] = price = request.POST.get('price','')
        context['background_photo'] = background_photo = request.POST.get('background-photo','')
        context['from_user'] = from_user = request.POST.get('from','')
        context['iteniary'] = iteniary = request.POST.get('iteniary','')
        context['days'] = days = request.POST.get('days','')
        context['destination'] = destination = request.POST.get('destination','')
        context['property_name'] = property_name = request.POST.get('property','')
        context['content'] = content = request.POST.get('content','')
        context['iteniary'] = iteniary = request.POST.get('iteniary','')

        #destinations and countries background photo created by not set
        brochure = Brochures(name=name, ref_id="xxx", adults=adults, children=children, infant=infant,
                    price=price, content=content, iteneary=iteniary)
        brochure.save()

        request.session['br_id'] = brochure.id
        return redirect('http://wilderness.maasaimara.com/generate/')

    return render_to_response(template_name, context, )



def generate_pdf(request, br_id, num):
    context = RequestContext(request)
    list_of_pages = ["http://127.0.0.1:8000/page"+x+"/" for x in list("123456")]
    pdfs = ["page"+x+".pdf" for x in list("123456")]
    merger = PdfFileMerger()
    client = pdfcrowd.Client("samuel254", "86e62657536d264e8217478d56abd72e")
    br_id = response.session["br_id"]
    brochure = Brochures.objects.get(br_id)

    # set HTTP response headers
    response = HttpResponse(mimetype="application/pdf")
    response["Cache-Control"] = "max-age=0"
    response["Accept-Ranges"] = "none"
    response["Content-Disposition"] = "attachment; filename=document-output.pdf"

    for num in list("123456"):
        path = "/home/samuel/Documents/Documents/wilderness/wilderness/static/pdf/"
        html = "http://wilderness.maasaimara.com/{1}/page{0}/".format(num,br_id)
        pdf = "page{0}.pdf".format(num)
        pdf_file = client.convertURI(html)
        local = open(pdf,'w')
        local.write(pdf_file)
        local.close()
        merger.append(open(pdf, 'r+b'))

    merger.write("document-output.pdf")
    response.write(merger)
    return response

The urls.py

from django.conf import settings
from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.views.generic import TemplateView

from django.contrib import admin
from views import generate_pdf,home

urlpatterns = patterns("",
    url(r"^$", home, name="home"),
    url(r"^(?P<br_id>d{4})/page(?P<num>[0-9]+)/", generate_pdf),

    url(r"^admin/", include(admin.site.urls)),
    url(r"^account/", include("account.urls")),
)

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

I need to confirm where the file is going, it's not crashing and returns the document-output.pdf but it's blank.

Hi,

merger.write("document-output.pdf")
response.write(merger)
return response

This might work:

merger.write(response)
return response

Though, it would be more memory efficient to write it to a temporary file and then either redirect to that url or stream out the temporary file.
