python-object（）没有参数错误

Question

I have following python classes.

class FileMaster(db.Entity):
        id = PrimaryKey(int, auto = True)
        description = Required(str)
        filesource = Required(str)
        createdby = Optional(int)
        createddate = Optional(datetime.datetime)
        updatedby = Optional(int)
        updateddate = Optional(datetime.datetime)
        filelists = Set('FileList')

class FileList(db.Entity):
        id = PrimaryKey(int, auto = True)
        filemaster = Required(FileMaster)
        filelocation = Required(str)
        createdby = Optional(int)
        createddate = Optional(datetime.datetime)
        updatedby = Optional(int)
        updateddate = Optional(datetime.datetime)
        transcripts = Set('Transcript')

The following line runs fine,

filemst = FileMaster(description=desc, filesource = filesourcepath) 

But the following line gives error "object() takes no parameters"

filelist = FileList(filemaster=filemst, filelocation='test')

Any one can help me on this?

我不确定是什么问题，但是我通过删除数据库中的表并为类使用了不同的名称来解决了问题。
