global name 'fetch_resources' is not defined

[MikeKJ]

Am I missing a dependancy?

from django.template.loader import get_template
from django.template import Context
import cStringIO as StringIO
import ho.pisa as pisa
from sx.pisa3 import pisaDocument
import cgi
from django import forms

def render_to_pdf(request, this_id):
    template = get_template('video/reflection.pdf')
    this_video = Part.objects.get(pk=this_id)
    context_dict = {'this_video': this_video,}
    context =  Context(context_dict)
    html = template.render(context)
    result = StringIO.StringIO()
    pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("UTF-8")), dest=result, link_callback=fetch_resources )
    if not pdf.err:
        return HttpResponse(result.getvalue(), mimetype='application/pdf')
    return HttpResponse('Error<pre>%s</pre>' % cgi.escape(html))

you need to implement the link callback (fetch_resources)
