Django消息未显示在重定向上，仅呈现
几天来，我一直在试图弄清楚为什么我的邮件不会显示在重定向上。如您所见，所有依赖项都存在于my settings.py文件中。我不认为这是问题所在，因为如果用户的密码在注册时不匹配，或者用户在登录时输入了错误的密码，我会在注册和登录时收到两条消息。我注意到它只适用于渲染，而不适用于重定向。接下来我将发布我的文件结构以及相关文件的图像 文件结构图像： 设置.pyDjango消息未显示在重定向上，仅呈现,django,django-messages,Django,Django Messages,几天来，我一直在试图弄清楚为什么我的邮件不会显示在重定向上。如您所见，所有依赖项都存在于my settings.py文件中。我不认为这是问题所在，因为如果用户的密码在注册时不匹配，或者用户在登录时输入了错误的密码，我会在注册和登录时收到两条消息。我注意到它只适用于渲染，而不适用于重定向。接下来我将发布我的文件结构以及相关文件的图像 文件结构图像： 设置.py from django.contrib.messages import constants as messages MESSAGE_

因此，最终，这些消息似乎不适用于重定向，但如果我呈现并声明文件夹和模板名称，它们确实有效。否则，如果存在重定向，则不会显示任何消息。我不太清楚是什么问题，也不清楚重定向为什么不能处理这些消息。一般来说，重定向会丢失所有信息/数据，因为它们正在启动一个新的HTTP请求。您必须传递URL参数标志或类似的内容。因此，您需要为“loginuser”创建额外的URL以接受可选参数。然后需要向重定向视图模板添加一些逻辑来查找可选参数。
