页面问题中的Django列表，“数据未出现”

Question

我遇到了这样的问题:将处理过的数据放入我的SQlite类数据库时没有列出任何结果。但是，我没有遇到错误代码。

相关页面将是一个页面，每个成员将看到他们的个人资料页面和信息。我希望根据我定义的名为user_id而不是id的列来提取数据。

views.py

        bilgilerim_cek=players.objects.get(user_id=id)
        context={
            'bilgiler': bilgilerim_cek,
            'bilgitum': players.objects.filter(user_id=id),
        }
        return render(request,'profil/bilgilerim.html', context)

bilgilerim.html

{% for bilgilerim_x in players %}
            {{ bilgilerim_x }}

您可以使用

{% for bilgilerim_x in players %}

在您的html中，但在您的视图中没有在上下文中定义“播放器”：

context={
            'bilgiler': bilgilerim_cek,
            'bilgitum': players.objects.filter(user_id=id),
        }
