誰かがWhooshインデックスに新しいドキュメントを追加するときに奇妙なエラーが発生するのを助けてくれますか?ここでWhooshインデックスに追加する際に奇妙なエラーが発生する
コードです:
def add_to_index(self, doc):
ix = index.open_dir(self.index_dir)
writer = AsyncWriter(ix) # use async writer to prevent write lock errors
writer.add_document(**self.get_doc_args(doc))
writer.commit()
def get_doc_args(self, doc):
return {
'id': u""+str(doc['id']),
'org': doc['org__id'],
'created': doc['created_date'],
'date': doc['received_date'],
'from_addr': doc['from_addr'],
'subject': doc['subject'],
'body': doc['messagebody__cleaned_message']
}
私は次のエラーを取得する:
TypeError('ord() expected a character, but string of length 0 found',)

不思議なことに、標準ライター(すなわちないAsyncWriter)を使用して、正確に同じコードが正常に動作します。私はここで何が欠けていますか?プロダクションでは、LockErrorsを避けるためにAsyncWriterを使用する必要があることに注意してください。
私は、すべての入力がユニコード文字列であることを確認したはずです。 – kuhnza
