我对Django相当陌生，现在对Django的概念不太熟悉。我创建了一个用户面板（来自simpleisbetterthancomplex.com），并希望与“ is_staff”用户一起实施审核。
目前，只有创建帖子/评论的用户才能编辑该帖子。作为is_staff用户，我还希望能够编辑所有帖子/评论。
这是编辑按钮：
protocol Foo {
func testPrint()
}
extension Foo {
func testPrint() {
defaultTestPrint()
}
func defaultTestPrint() {
print("Protocol extension call")
}
}
struct Bar: Foo {
func testPrint() {
// Calling self or super go call default implementation
defaultTestPrint()
print("Call from struct")
}
}
let sth = Bar()
sth.testPrint()
我认为我可以这样做：
{{ post.message }}
{% if post.created_by == user %}
<div class="mt-3">
<a href="{% url 'edit_post' post.topic.board.pk post.topic.pk post.pk %}"
class="btn btn-primary btn-sm"
role="button">Edit</a>
</div>
{% endif %}
尽管我可以通过正确的超链接来编辑帖子，但会收到“找不到页面”错误。
什么是对我的论坛进行审核的方法？

很难说出您的代码出了什么问题。似乎两个代码示例都应显示相同的按钮。
请注意，在这种情况下，应该将if更改为稍微复杂一点的 {% if user.is_staff or post.created_by == user %}来使用单个按钮和标记。这应该具有消除两个按钮之间所有可能的差异的附加效果。
如果您只想编辑/删除帖子，那么最简单的方法可能是使用内置的django管理面板。如果您使用django startproject，则您的应用程序已经有一个！尝试转到localhost:8000/admin（默认情况下）进行检出。

编辑：我认为我可以看到问题。您可以通过(created_by=self.request.user)在PostUpdateView中过滤查询集。当与其他用户（例如主持人）打交道时，此过滤器的工作方式有所不同。尝试更改视图以反映这一点。

问题是edit_post返回的URL。此视图仅允许访问该帖子的所有者，因此没有其他人可以访问此视图。
您需要添加到视图中，以允许具有is_staff = True的用户访问此视图。
问题在于查询集定义会滤除用户未创建的模型。但是您要保留此设置，以便其他用户没有访问权限。
您可以删除get_queryset调用并调整调度方法，以仅允许所有者或工作人员查看。但是我建议保持此状态不变，并添加一个新的主持人更新视图，并使用d括号整理权限。像这样的东西
