对 'create-ordercontent' 进行反转，但未找到参数 '('',)'。尝试了 1 种模式：['store/create\-ordercontent/(?P<order_id>[^/]+)$']

Question

我是 Django 的新手。我正在尝试将 id 从 1st url 传递到 2nd ur.

Reverse for 'create-ordercontent' with arguments '('',)' not found. 1 pattern(s) tried: ['store/create\-ordercontent/(?P<order_id>[^/]+)$']

urls.py

path('list-ordercontent/<order_id>', OrdercontentListView.as_view(), name='list-ordercontent'),
path('create-ordercontent/<order_id>', create_ordercontent, name='create-ordercontent'),

view.py

class OrdercontentListView(ListView):
    model = Ordercontent
    template_name = 'store/list_ordercontent.html'
    context_object_name = 'ordercontent'

    def get_queryset(self):
        model = Ordercontent
        order = self.request.resolver_match.kwargs['order_id']
        return model.objects.filter(order=order)

在 list-ordercontent.html 中，我尝试使用相同的 order_id 来传递我想要的变量，但它不正确。我想知道如何将 order_id 用于另一个 url，在我的程序中它是用于创建的 url。

Answer 1

ListView 不会将视图接收到的关键字参数添加到上下文中，如果您希望它们在上下文中，您应该通过覆盖 get_context_data:[=12 自己添加它们=]

class OrdercontentListView(ListView):
    型号 = 订单内容
    template_name = 'store/list_ordercontent.html'
    context_object_name = 'ordercontent'

    def get_queryset(自我):
        型号 = 订单内容
        order = self.kwargs['order_id'] # 不需要访问 `request.resolver_match.kwargs` 它们存在于 `self.kwargs`
        return model.objects.filter(订单=订单)
    
    def <b>get_context_data</b>(self, **kwargs):
        context = super().get_context_data(**kwargs)
        <b>上下文['order_id'] = self.kwargs['order_id']</b>
        return 上下文
