Python 使用烧瓶上载和烧瓶WTF上载未通过验证

我似乎无法理解为什么一个字段在另一个字段成功上传文件时失败。我可以上传一张照片很好。。。但当涉及到pdf时，我无法让它通过验证。我已经搜遍了我的代码，找不到任何错误。有趣的是，我可以通过手动上传设置上传照片，这对我来说毫无意义。我猜我是如何配置flask wtf和flask上传的，但鉴于网上没有关于如何将两者结合使用的文档，我不得不尽我所能

任何帮助都将不胜感激，因为我需要上传PDF，这让我感到困惑

代码如下。。。非常感谢

{{eqform.hidden_tag（）}}


{{eqform.name.label}}:{{eqform.name}


{{eqform.photo.label}:{{{eqform.photo}}

照片必须是png、jpg或jpeg格式。


{{eqform.manual.label}}:{{{eqform.manual}}

手册必须是pdf格式。

我犯了一个愚蠢的错误：

UPLOADED_MANUALS_ALLOW = 'pdf'
UPLOADED_PHOTOS_ALLOW = 'png, jpg, jpeg'

这两个我声明为字符串的允许扩展列表。。。将其更改为：

UPLOADED_MANUALS_ALLOW = ('pdf')
UPLOADED_PHOTOS_ALLOW = ('png', 'jpg', 'jpeg')

然而，值得注意的是：该列表仍然无法处理单个项目，因此我必须添加两个：

上传的手册允许=（'pdf'，'pdf'）

---

我一直在玩shell中的上传集。我的问题似乎与我的应用程序没有正确使用配置中设置的项目有关。我的两个上传集中似乎都有默认的允许扩展列表，而不是我定义的那些。。。事情总是那么愚蠢。我把我的扩展列表作为一个字符串。将“png，jpg，jpeg”更改为（“png”，“jpg”，“jpeg”），瞧！值得注意的是。。。有一个扩展名的列表在我的pdf中仍然不起作用。。。所以我不得不把它做成（'pdf'，'pdf'），我认为“列表仍然不能处理单个项目”只是Python元组的问题。请尝试

upload\u MANUALS\u ALLOW='pdf'，

或

upload\u MANUALS\u ALLOW=（'pdf'，）
