对于我当前的项目,我正在使用python瓶。目前,我正在尝试保存用户以表格形式上载的文件,但这会引起上面显示的错误。我以最好的方式跟踪文档,但是无论我尝试了什么,它都会出现此错误。
这里是功能:
def uploadFile(file, isPublic, userId, cu, dirId=-1): """Takes a bottle FileUpload instance as an argument and adds it to storage/media as well as adds its info to the database. cu should be the db cursor. isPublic should be a bool. userId should be the uploaders id. dirId is the directory ID and defaults to -1.""" fakeName = file.filename extension = os.path.splitext(file.filename)[1] cu.execute("SELECT * FROM files WHERE fileId=(SELECT MAX(fileId) FROM files)") newId = cu.fetchone() if newId==None: newId = 0 else: newId = newId[1] if debugMode: print(f"newId {newId}") fileName = f"userfile-{newId}-{userId}.{extension}" file.save(vdata["m_folder"] + "/" + fileName) cu.execute("INSERT INTO files VALUES (?, ?, ?, ?, ?, ?)", (userId, newId, dirId, fakeName, fileName, isPublic)) cu.connection.commit()
有人知道这可能是什么问题吗?

似乎您尚未打开要写入的文件。您可以这样做:
