用于删除 post returns Https 200 而不是 302 的 Django 测试用例

Question

我正在为我的 Django 项目中的 Posts 应用编写测试用例。我定义了用于添加新 post、列出 post、查看 post 的详细信息、编辑 post 和删除 post 的视图。添加新的 post 会将页面重定向到该页面的详细视图，删除 post 会将页面重定向到列表视图。在为此编写测试时，我得到了预期的新 post 的 https 响应代码 302，但是对于删除 post，我只得到了 https 响应 200，而它应该是 302。

在下面添加必要的代码。如果需要，请随时询问与此相关的更多代码。

有什么概念是我遗漏的吗？欢迎任何潜在客户。

提前致谢。

Answer 1

response = self.client.get(reverse('delete',args='1'))

使用 GET 请求，您要求的模板 'deleteview.html' 需要填写才能删除对象。因此，状态代码 200 是正确的。

您应该使用POST（或DELETE）请求。这将删除对象并重定向到 success_url = reverse_lazy('lists')。因此，您将获得状态代码 302.

想清楚的看一下DeleteView的代码。
