我有一个base_planner.html，它包含一个导航栏和一个侧边栏。当我在任何其他模板中扩展这个基础时，导航栏和侧边栏都是继承的，但侧边栏没有任何必须存在的内容。我没有犯任何错误。唯一具有侧边栏内容的模板是主页，它只是一个ListView html页面(projectsmodel_list.html)，包含一行：{% extends 'app_plannerbase_planner.html' %}
以下是我的views.py(我希望TestView继承侧边栏内容)：
class ProjectListView(LoginRequiredMixin, generic.edit.FormMixin, generic.ListView):
context_object_name = 'project_list'
model = ProjectsModel
form_class = ProjectsForm
success_url = reverse_lazy('app_planner:planner_home')
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['create_project_form'] = ProjectsForm()
return context
def form_valid(self, form):
project_name = form.cleaned_data['project_name']
project_author = self.request.user
create_project_form_item = ProjectsModel(project_name=project_name, project_author=project_author)
create_project_form_item.save()
return super().form_valid(form)
def form_invalid(self, form):
return super().form_invalid(form)
def post(self, request, *args, **kwargs):
self.object_list = self.get_queryset()
form = self.get_form()
if form.is_valid():
return self.form_valid(form)
else:
return self.form_invalid(form)
class TestView(generic.TemplateView):
template_name = 'app_planner/test.html'
这是我的urls.py:
app_name = 'app_planner'
urlpatterns = [
path('', views.ProjectListView.as_view(), name='planner_home'),
path('test/', views.TestView.as_view(), name='test'),
]
这是我base_planner.html:的正文

这是我的测试.html：

{% block content %}
<h1>Check the sidebar</h1>
{% endblock %}
我尝试过更改模板，将ProjectListView的内容添加到其他视图，创建一个单独的sidebar.html，并在base_planner.html的｛%block sidebar%｝中使用｛%include‘app_planner/sidebar.html%｝调用其他模板中的｛%super.sidebar%n｝，但都没有成功。我一直看到一个空的侧边栏。这是我第一次面对这样的问题，因为｛%extend%｝对我来说一直都是正确的。我不明白错误在哪里。
拉斐尔给了我一个好主意。真的，我只是忘了给我的TestView显示内容。这个效果很好，谢谢！
