iam 尝试使用 django 创建报告，但由于某种原因阿拉伯语单词被编辑了 这是 pdf 的示例
这是我的查看功能 这个功能和模板在下载 pdf 时工作得很好，但是当它渲染阿拉伯语时它不起作用 我已经下载了这个阿拉伯字体 NotoKufiArabic-VariableFont_wght.ttf 但由于某种原因它无法工作
from django.http import HttpResponse
from django.template.loader import get_template
from xhtml2pdf import pisa
from io import BytesIO
from django.shortcuts import get_object_or_404
from ..models import Supplier, TransactionModel
from django.db.models import Sum
def generate_pdf_report(request, supplier_name):
supplier = get_object_or_404(Supplier, supplier_name=supplier_name)
transactions = TransactionModel.objects.filter(supplier_name=supplier).order_by('payment_date')
total_paid = transactions.aggregate(Sum('payment_amount'))['payment_amount__sum'] or 0
remaining_amount = supplier.total_amount - total_paid
context = {
'supplier': supplier,
'transactions': transactions,
'total_paid': total_paid,
'remaining_amount': remaining_amount,
}
template = get_template('supplier_report.html')
html = template.render(context)
result = BytesIO()
pdf = pisa.pisaDocument(BytesIO(html.encode("UTF-8")), result, encoding='UTF-8')
if not pdf.err:
response = HttpResponse(result.getvalue(), content_type='application/pdf')
response['Content-Disposition'] = f'attachment; filename="{supplier_name}_report.pdf"'
return response
return HttpResponse('Error generating PDF', status=400)
这是我的模板

这里有一个小错字
from ..models import Supplier, TransactionModel
你在这里输入“..” 更新代码：
