I am trying to produce pdf from html using the following code, but
unable to do so, it gives an error that, global name 'results' is not
defined. Please tell me how to use this view.

def render_to_pdf(template_src, context_dict):
template = get_template(template_src)
context = Context(context_dict)
html = template.render(context)
result = StringIO.StringIO()

pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")),
result)
if not pdf.err:
return HttpResponse(result.getvalue(), mimetype='application/pdf')
return HttpResponse('We had some errors<pre>%s</pre>' % escape(html))

def myview(request):
#Retrieve data or whatever you need
return render_to_pdf(
'report/pdf.html',
{
'pagesize':'A4',
'mylist': results,
}
)

in the report/pdf.html there is:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>My Title</title>
<style type="text/css">
@page {
size: {{ pagesize }};
margin: 1cm;
@frame footer {
-pdf-frame-content: footerContent;
bottom: 0cm;
margin-left: 9cm;
margin-right: 9cm;
height: 1cm;
}
}
</style>
</head>
{% block report %}
<body>
<div>
{% for item in mylist %}
{{item}}
{% endfor %}
</div>
<div id="footerContent">
{%block page_foot%}
Page <pdf:pagenumber>
<pdf:barcode>
{%endblock%}
</div>
</body>
</html>

The pisa pypi entry suggests that you switch to xml2pdf: https://pypi.python.org/pypi/xhtml2pdf

In myview(), you are setting "mylist" to results but I don't see results
defined in myview() anywhere.
