Мне трудно создавать PDF-файлы в Django. Согласно моему предыдущему вопросу я сталкиваюсь с той же ошибкой.
Когда я запускаю следующий код, я получаю 'list' object has no attribute 'encode'
, PDF-файл сохраняется в папке мультимедиа, но это обычный текстовый файл. Я думаю, что объект, о котором идет речь, - это набор запросов sections
.
@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 with 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 a Django HTTP response
file.seek(0)
pdf = file.read()
file.close() # Don't forget to close the file handle
return HttpResponse(pdf, mimetype='application/pdf')
вывод кли:
<class 'lld.models.Document'>
<type 'list'>
<type 'dict'>
<class 'django.template.backends.django.Template'>
<class 'django.utils.safestring.SafeText'>
<type 'file'>
и ошибка:
