Я покрываю файл HTML в PDF, используя weasyprint в веб-приложении Django. Все работает нормально, но работает очень медленно при конвертации HTML в PDF. Когда я конвертирую, это занимает более двух минут. Я использую шрифт Bangla в своем HTML-файле.
это мой код views.py
def get_pdf_file(request, customer_id, sys_type):
sys_type = customer_id
area = "pdf"
site_credit = site_credit1
time_now = timezone.now()
customers = get_object_or_404(CustomerInfo, pk=customer_id)
due_taka_track = customers.duetaka_set.all()
if due_taka_track == None:
due_taka_track = 0
unpaid_taka = int(customers.customer_price -
customers.customer_due_taka_info)
due_taka_track = customers.duetaka_set.all()
sum_cost_taka = due_taka_track.aggregate(
sp=Sum('customer_due')).get('sp', 0)
if sum_cost_taka == None:
sum_cost_taka = 0
total_paid_taka = sum_cost_taka + customers.customer_due_taka_info
payment_status = 'complete'
payment_message = 'Full Paid'
remain_taka='PAID'
remain_msg=''
if customers.customer_due_taka_info < customers.customer_price:
payment_status = 'incomplete'
payment_message = 'সম্পূর্ন টাকা পরিষোধ করা হয়নি'
remain_msg='টাকা বাকী আছে'
baki_ase="পাওনা আছে "
remain_taka = customers.customer_price - customers.customer_due_taka_info
context = {'customers': customers,

html_string = render_to_string('shop/pdf_invoice.html', context)
html = HTML(string=html_string)
result = html.write_pdf()
response = HttpResponse(content_type='application/pdf;')
response['Content-Disposition'] = 'inline; filename=invoice'+sys_type+'.pdf'
response['Content-Transfer-Encoding'] = 'UTF-8'
with tempfile.NamedTemporaryFile(delete=True) as output:
output.write(result)
output.flush()
output = open(output.name, 'rb')
response.write(output.read())
return response
