我似乎無法弄清楚爲什麼一個字段失敗,而另一個字段卻無法成功上傳文件。我可以很好地上傳照片......但是當涉及到PDF時,我無法通過驗證。我已經爲我的代碼搜索了任何錯誤,但找不到任何東西。有趣的是,我可以通過手動上傳設置上傳照片,這對我來說沒有任何意義。我猜測我已經配置了flask-wtf和flask-uploads,但是由於在線上沒有關於如何使用這兩者的文檔,我只好盡力而爲。上傳Flask-Uploads和Flask-WTF失敗驗證
任何幫助將不勝感激,因爲我需要上傳pdfs,這讓我難住。
代碼如下...謝謝!

我一直在玩shell中的上傳集。看來我的問題與我的應用程序不正確使用我的配置中設置的項目有關。我的上傳集似乎都有默認的允許擴展名列表,而不是我定義的。 – Chockomonkey
想通了......總是那麼愚蠢。我有我的擴展名列表作爲字符串。將'png,jpg,jpeg'改爲('png','jpg','jpeg')和VOILA!有趣的是......有一個擴展名的列表在我的PDF文件中仍然不起作用...所以我必須把它做成('pdf','PDF') – Chockomonkey
