Very cool!
Thanks so much, Ned!! Certainly this will do the trick. ( I have a demo of
this app coming up on Thursday and it would be great if I could actually show
the pdfs rendered.)
Sincerely,
-Warren

Subject: Re: Django app serves PDFs but browser doesn't render them
We serve PDFs, both in-browser, and out. Here the lines to set the type and
disposition:
response = HttpResponse(pdfbytes, mimetype='application/pdf')
response['Content-Disposition'] = 'attachment; filename=foo.pdf'
return response
Here pdfbytes are the actual bytes of the PDF file. With the
Content-Disposition line, Firefox will display the Save As dialog to save the
file someplace. Without that line, the PDF is displayed in the browser.

Hi All!
We have a Django application that uses a form to allow users to select
offices and it sends them off to a pdf. At the present time we are using
FireFox on a Linux box and we are just using the Django loopback server for
the time being. This means that we don't have a secondary, or even a
primary instance of Apache working for us.
So when you select an office and the pdf is served up you see binary codes
dumped on your screen.
That sounds like you haven't set the mimetype correctly. Firefox should
ask what application to use for anything it can't render natively. The
fact that you are seeing bytes sent to the screen suggests you are
sending it across with the HTML or some text-derivative mimetype so that
Firefox things it should display this directly.
By itself, if I fire up FireFox and go to the pdfs, I am prompted for what
viewer to use, and choose postscript viewer and all is well. So the browser
is capable of rendering pdfs properly.
Any constructive comments on this? Any advice on getting the browser to
actually render the pdfs?
Browsers usually (I was going to say always, but I'm not sure what
native-PDF-underneath-MacOS does) hand off PDF rendering to a
third-party app. Sometimes that third-party app it is configured as a
browser plugin.
I personally have no experience to share here because I prefer to use an
external app for PDF rendering, as my browser window is not the right
size for viewing generated-for-print-page documents, so I like being
able to resize them separately.
Regards,
Malcolm
