Hi I am trying to add a page to a pdf file that I am building using reportlab and return it using a Django response. The page I am trying to add comes from an external URL.

I would like to add the page without the use of additional lib such as PyPDF or pdfrw. I have a feeling it might have something to do with reportlabs Flowable class. What I would like to know is how to:

• read the pdf from the url


• add the pdf page to the report lab pdf


• if possible how to achieve this using only reportlab

I have created the canvas this way:

from reportlab.pdfgen.canvas import Canvas
from reportlab.lib.pagesizes import A6
from django.http import HttpResponse

 response = HttpResponse(content_type='application/pdf')
 response['Content-Disposition'] = 'attachment; filename="somefile.pdf"'
 canvas = Canvas(response, pagesize=A6)

And have added content and pages using the simple canvas methods:

 canvas.line(5*mm, 111*mm, 100*mm, 111*mm)
 canvas.line(5*mm, 83*mm, 100*mm, 83*mm)
 canvas.line(52*mm, 83*mm, 52*mm, 111*mm)
 canvas.showPage()

 canvas.drawString(10*mm, 78*mm,'ITEM DESCRIPTION: ')
 canvas.drawString(10*mm, 65*mm,'PAYMENT TYPE: ')
 canvas.drawString(10*mm, 53*mm,'SHIPPER ORDER ID: ')
 canvas.showPage()
 canvas.save()

 return response

Using this code, I am able to return a pdf as a response. But would like to know how to add pages from a url thanks!

python-3.x django-rest-framework reportlab
