Django与比萨的pdf问题

我想使用pisa为pdf文件生成html模板。我相信我拥有我需要的所有包裹,但我似乎遇到了问题。以下是我的观点 远我所做的。

编辑:这是我最新的网址,观点和视频模板。

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

在模板中,我有这个标签。

<a href="{% url c2duo.views.render_pdf invoices.pk %}">

我不知道这会有多大帮助,但这是我用来渲染pdf的功能:

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

只是为了好玩,试试这个:

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)

如果您仍然遇到错误,我猜这个错误可能在比萨。你确定它是最新的吗?
