You called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH
錯誤資訊如下:
RuntimeError at /picloadYou called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH set.
Django can't redirect to the slash URL while maintaining POST data. Change your form to point
to 127.0.0.1:8000/picload/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.
表單欄位action以'/'結尾，(action="/picsave/)，嘗試修改settings檔案，設定了APPEND_SLASH = False屬性，
bug仍存在。最後將 應用的 urls中對應的路徑末去掉'/'，(r'^picsave/$'，去掉表示式中的'/')，bug修復。PS：仔細瞭解APP中urls路徑配置詳細規則
