Python 为什么这个函数有一个类型错误？

当我想将订单详细信息打印为PDF文件时，它提供以下信息：

错误：

admin_order_pdf() got an unexpected keyword argument 'order'

职能：

@staff_member_required
def admin_order_pdf(request, order_id):
    order = get_object_or_404(Order, id=order_id)
    html = render_to_string('orders/pdf.html', {'order': order})
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = f'filename=order_{order.id}.pdf'
    weasyprint.HTML(string=html).write_pdf(response,
                                           stylesheets=[weasyprint.CSS(
                                               settings.STATIC_ROOT + 'css/pdf.css'
                                           )])
    return response

resp = admin_order_pdf(request=req, order_id=123)

您需要接受

order

作为关键字参数：

def admin_order_pdf(request, order):

或者根据函数的要求，将调用代码更改为传递

order\u id

：

@staff_member_required
def admin_order_pdf(request, order_id):
    order = get_object_or_404(Order, id=order_id)
    html = render_to_string('orders/pdf.html', {'order': order})
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = f'filename=order_{order.id}.pdf'
    weasyprint.HTML(string=html).write_pdf(response,
                                           stylesheets=[weasyprint.CSS(
                                               settings.STATIC_ROOT + 'css/pdf.css'
                                           )])
    return response

resp = admin_order_pdf(request=req, order_id=123)

没有

订单

关键字。它是

order\u id

。您没有显示如何调用该函数，因此无法帮助它工作，谢谢：D
