小编Moh*_*aad的帖子

我真的不明白是什么导致了错误，我检查了文档，这里有一个非常相似的例子是我使用的应用程序下的 views.py、urls.py 和模板

视图.py

class SchoolListView(ListView):
    context_object_name = 'schools'
    model = models.School

网址.py

from django.urls import path
from . import views

#My name space
app_name = 'basicapp'
urlpatterns = [
    path('', views.ListView.as_view(), name='list'),
    path('details', views.DetailView.as_view(), name='details')
]

和我的模板

{% extends 'basicapp/basicapp_base.html'%}
{% block body_block %}
  <div class="jumbotron">
    <h1>Welcome to list of all schools</h1>
    <ol>
      {% for school in schools %}
      <h2><li><a href="{{school.id}}">{{school.name}}</a></li></h2>
      {% endfor %}
    </ol>

{% endblock %}

我得到这个我不太明白的错误

Exception Type: ImproperlyConfigured
Exception Value:    
ListView is missing a QuerySet. …
