提问by Михаил Павлов

I'm going through django tutorial and having the TypeError 'method' object is not subscriptable. The error is thrown when the following code executed

我正在阅读 django 教程,并且 TypeError 'method' 对象不可下标。执行以下代码时抛出错误

class ProductListView(ListView):
    model = Product
    queryset = Product.objects.all()

    def get_context_data(self, *args, **kwargs):
        context = super(ProductListView, self).get_context_data(*args, **kwargs)
        context["now"] = timezone.now()
        context["query"] = self.request.GET.get["q"]
        return context

    def get_queryset(self, *args, **kwargs):
        print(self.request)
        qs = super(ProductListView, self).get_queryset(*args, **kwargs)
        query = self.request.GET.get["q"]
        if query:
            qs = self.model.objects.filter(
                Q(title__icontains=query) |
                Q(description__icontains=query)
            )
            try:
                qs2 = self.model.objects.filter(
                    Q(price=query)
                )
                qs = (qs | qs2).distinct()
            except:
                pass
        return qs

The problem line is query = self.request.GET.get["q"]

问题线是 query = self.request.GET.get["q"]

How do I solve this issue?

我该如何解决这个问题?

The problematic line tries to use subscript notation with method getof the mapping GET:

有问题的行尝试将下标符号与get映射方法一起使用GET

query = self.request.GET.get["q"]

The method should be called with:

该方法应调用:

query = self.request.GET.get("q")
