Django - Pisa generated pdf doesn't have spaces
I'm using Django and my code to render the PDF is really typical:
t = loader.get_template('back/templates/content/receipt.html')
c = RequestContext(request, {
'pagesize': 'A4',
'invoice': invo开发者_如何学JAVAice,
'plan': plan,
})
html = t.render(c)
result = StringIO.StringIO()
pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("UTF-8")), result)
if not pdf.err:
return HttpResponse(result.getvalue(), mimetype="application/pdf")
And the receipt.html is nothing unusual:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Squizzal Receipt</title>
<style type="text/css">
@page {
size: {{pagesize}};
margin: 1cm;
word-spacing 1cm;
@frame footer {
-pdf-frame-content: footerContent;
bottom: 0cm;
margin-left: 9cm;
margin-right: 9cm;
height: 1cm;
}
}
</style>
</head>
<body>
<h1>Your Receipt</h1>
<<SNIP>>
but none of the spaces in the pdf are rendered. All the words are right next to each other. I've tried normal spaces and " " and the result is the same. For example the above would appear as "YourReceipt" in the pdf.
When I try using the command line version of pisa, it generates the pdf just fine with spaces between the words.
Any thoughts?
I had this same issue and didn't want to force the PDF to be downloaded from the browser. This turned out to be a platform specific issue: Google Chrome's native PDF viewer plugin fails to render spaces in certain documents on certain Linux distros when Microsoft TrueType fonts are not installed. See http://www.google.com/support/forum/p/Chrome/thread?tid=7169b114e8ea33c7&hl=en for details.
I fixed this by simply running the following commands in bash (adjust for your distro; this was on Ubuntu):
$ sudo apt-get install msttcorefonts
(Accept the EULA during the install process)
$ fc-cache -fv
After restarting Chrome (important!), the native PDF viewer correctly displayed the PDF with spaces.
Ok thanks to akonsu the problem seems to be how Django's HttpResponse is being treated (either on the server side or on the browser side).
Instead of
return HttpResponse(result.getvalue(), mimetype="application/pdf")
Use:
resp = HttpResponse(result.getvalue(), mimetype="application/pdf")
resp['Content-Disposition'] = 'attachment; filename=receipt.pdf'
return resp
This at least produces a result without spaces. Still no idea why the first way wasn't working.
