如何修复列表视图未在Django中显示！

当我看到html file中没有显示数据时，我在基于类的视图中添加列表视图，我很累要解决，请您帮我！

这是我的 views.py

class Buy_List_View(ListView):
    model = user_buy
    template_name = 'index.html'

这是我的 models.py

class user_buy(models.Model):
    users = models.ForeignKey(user_register_model,on_delete=models.CASCADE)
    payment_method = models.CharField(max_length=500)
    price = models.IntegerField()
    limits = models.IntegerField()

这是我的 index.html

{% for buy in user_buy_list %}
    <tr>
        <td><a href="#">{{ buy.users }}</a></td>
        <td>{{ buy.payment_method }}</td>
        <td>{{ buy.price }}</td>
        <td>{{ buy.limits }}</td>
    </tr>
{% endfor %}

这是我的 urls.py

from . import views
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('', views.index,name='index'),
    path('accounts/signup/', views.user_reg,name='register'),
    path('profile/<username>', views.user_profile, name='user_profile'),
    path('buy/form/seller',views.Buy_List_View.as_view(),name='buy')
]

Answer 1

views.py

class Buy_List_View(generic.ListView):
    model = user_buy
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        return context

    def get_queryset(self):
        user_buy = self.model.objects.all()
        return user_buy

您必须在模板中更改对象名称

{% for buy in object_list %}
    <tr>
        <td><a href="#">{{ buy.users }}</a></td>
        <td>{{ buy.payment_method }}</td>
        <td>{{ buy.price }}</td>
        <td>{{ buy.limits }}</td>
    </tr>
{% endfor %}

我的urls.py中有问题，我想在主页上显示，但是我写了个人资料页面，这就是为什么我看不到需要更改而不是此原因

from . import views
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('', views.index,name='index'),
    path('accounts/signup/', views.user_reg,name='register'),
    path('profile/<username>', views.user_profile, name='user_profile'),
    path('buy/form/seller',views.Buy_List_View.as_view(),name='buy')
]

为此

from . import views
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('', views.Buy_List_View.as_view(),name='index'),
    path('accounts/signup/', views.user_reg,name='register'),
    path('profile/<username>', views.user_profile, name='user_profile'),
]

因为我想在主页上显示而不是此页面！
