Django pdf question with pisa
Question
I want to generate a html template to a pdf file using pisa. I believe I have all the packages I need but I seem to be having problems doing so. Here is my view below so far what I have done.
EDIT: Here is my latest url, views & template.
url.py
(r'^index/render_pdf/(?P<id>\d+)/$', render_pdf),
views.py
def fetch_resources(uri, rel):
path = os.path.join(settings.MEDIA_ROOT, uri.replace(settings.MEDIA_URL, ""))
return path
def render_pdf (html, id):
invoice_items_list = Invoice_Items.objects.filter(pk=id)
result = StringIO.StringIO()
pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), dest=result, link_callback=fetch_resources)
return result
In a template, I have this tag.
<a href="{% url c2duo.views.render_pdf invoices.pk %}">

I dont know how much this will help, but this is the function i use to render the pdf:
def fetch_resources(uri, rel):
"""
Callback to allow pisa/reportlab to retrieve Images,Stylesheets, etc.
`uri` is the href attribute from the html link element.
`rel` gives a relative path, but it's not used here.
"""
path = os.path.join(settings.MEDIA_ROOT, uri.replace(settings.MEDIA_URL, ""))
return path
def render_pdf (html):
result = StringIO.StringIO()
pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), dest=result, link_callback=fetch_resources)
return result

Just for fun, try this instead:
def render_to_pdf(template_src, context_dict):
html = "<html><head><title>Title</title></head><body><h1>Hello</h1></body></html>"
result = StringIO.StringIO()
pdf = pisa.pisaDocument(StringIO.StringIO(html), result)
if not pdf.err:
return http.HttpResponse("" % (repr(result.getvalue())))
else:
raise Exception("The error was %s" % pdf.err)
If you still encounter an error, I'm guessing the error might be in pisa. Are you sure it's up to date?
