Python Django：如何显示数据库中登录的用户数据

我正在开发一个发票管理系统，用户可以在其中添加发票数据，并将其保存在数据库中，每当用户登录时，数据都会显示在主页上。但是，如果任何用户登录主页时也显示其他用户的数据，但我只需要活动用户的数据，则会出现问题。你们能帮帮我吗

这是我的主页，你可以看到我是通过用户1登录的，但在主页上也会显示用户2的数据

这是我的密码

您必须覆盖列表视图上的

get_queryset（）

，例如，仅包括所需用户的发票。（您还需要在“更新”视图上执行此操作，以避免用户能够编辑彼此的发票。）

另一方面，除非模型的单个实例实际表示发票列表，否则您的模型应称为

发票

class InvoiceListView(ListView):
    model = Invoicelist
    template_name = 'invoicedata/home.html'
    context_object_name = 'invoices'

    def get_queryset(self):
        return self.model.objects.all().filter(issuer=self.request.user)

嘿，AKX感谢你们的快速响应，实际上更新视图工作正常，但列表视图出现问题，建议的解决方案不起作用，我试过了，但现在它没有显示任何内容。顺便说一句，我已经添加了更新页面，您可以将其签出您的创建视图集

author

；在这种情况下，你会想过滤

（author=self.request.user）

，当然。嘿，谢谢你的工作，但是当我从所有用户注销时，主页会给我一个错误“TypeError at/'AnonymousUser'object is not iterable”“'AnonymousUser'是用户未登录时请求使用的默认用户。您应该在

get\u queryset（）

中添加

if request.user.is\u authenticated

子句，如果用户未登录，只需返回一个空列表

[]

@alexherez，最好是

self.model.objects.none（）

，在这种情况下，它也是一个查询集。

class InvoiceListView(ListView):
    model = Invoicelist
    template_name = 'invoicedata/home.html'
    context_object_name = 'invoices'

    def get_queryset(self):
        return self.model.objects.all().filter(issuer=self.request.user)
