我有一个简单的应用程序，它接受条目/任务并将它们分配给适当的收件箱。 模型，模板和视图如下。我想要做的是修改视图，以便我可以 在我的表单中有一个功能“删除”按钮（与“添加/提交”按钮一起，就像在管理表单中一样。）：
models.py

任何人都可以帮助我指出正确的方向。文档似乎暗示我需要单独的视图和网址，但我很确定这可以在一个视图中完成？
答案 0 :(得分：0)
The docs seem to suggest that I need separate views and urls but I'm pretty sure this can be accomplished in a single view?
我猜你可以通过传入不同的POST参数来实现这一点，具体取决于按下了哪个按钮。尽管如此，这仍然是一件非常奇怪的事情。将它们分成不同的视图更加整洁，更易于维护。
对于链接到模板的视图，您可能会感到误解。有两个单独的视图（一个用于提交，一个用于删除）绝不会影响您显示链接到模板中这些视图网址的两个按钮的能力。
如果你担心代码重用（基于函数的视图经常共享大量代码，那么这是一个合理的抱怨）那么我建议调查class based views
编辑：
只是使用按钮链接到第二个“删除”视图：
<div class="your-button-class" href="{% url "your-delete-view" pk=object.pk %}></div>
