python - Django / xhtml2pdf - object has no attribute 'encode' -

-

i'm having hard time producing pdf's in django. per previous question i'm running same error.
when run following code 'list' object has no attribute 'encode', pdf saved in media folder plain text file. think object being referred sections queryset.

@login_required def generate_pdf(request, slug):     # prepare context     document = get_object_or_404(document, slug=slug)     sections = \         get_list_or_404(section.objects.filter                         (associated_document__startswith=document.slug))     data = {'document': document, 'sections': sections}      # render html content through html template context     template = get_template('lld/lld_pdf.html')     html = template.render(context(data))     file = open('/home/project/media/test.pdf', "w+b")     print type(document)     print type(sections)     print type(data)     print type(template)     print type(html)     print type(file)     pisastatus = pisa.createpdf(html.encode('utf-8'), dest=file)     # return pdf document through django http response     file.seek(0)     pdf = file.read()     file.close()            # don't forget close file handle     return httpresponse(pdf, mimetype='application/pdf')

cli output:

<class 'lld.models.document'> <type 'list'> <type 'dict'> <class 'django.template.backends.django.template'> <class 'django.utils.safestring.safetext'> <type 'file'>

and error:
