peewee.ProgrammingError: (1146, "Table 'test.lagou_position_info' doesn't exist")

プロジェクトの概要はscrapyを使ってすべてのネット上の技術職の情報を引き出してmysqlに保存して、それからpeeweeが非常に軽量なORMフレームワークだと言っているので、私は持ってきて試して、それから穴を踏んだ.

完全なtracebackは上記の通りですが、何も見えません.唯一役に立つと思う情報は「Table」testです.lagou_position_info'doesn't exist」ですが、私自身が使っているのはdbです.create_tables(lagou_position_info,safe=True)は、テーブル構造を自動的に作成するため、結果としてテーブルが作成されていないことを注意します.
公式の例を振り返ってみました.

db.create_tables([Person, Pet])

はい、実はパラメータはlistで、私は直接modelに伝わりました.のdbに変更します.create_tables([lagou_position_info],safe=True)、その後は正常でしたが、この異常にツッコミを入れたいのは自分があまりにも不注意です.
