(SQLITEとの接続、Flaskで表示させる)

(FlaskにおけるPOST,GETの扱い方)

(登録フォームを追加)

(検索フォームを追加)

登録窓までが出来たのでそれを合体、そして検索フォームまで作っていきます。

#検索のやり方
```
SELECT (カラム) FROM (テーブル名)　WHERE (検索するカラム)  =(イコール) or LIKE "(文字列)" 
```

SQLITEの文字列検索をそのまま使うだけ。
なぜかFTS（全文検索とやら）が自分の環境だとできなかったので名前なら名前からのみ検索出来ない

#これで一応必要な機能は全て実装できた。
が、しかし・・・

##app.py

#**な、なんだこれは・・・**

WEBアプリとしてなりたってすらいいない・・・

次回以降作り直すことを決意した。
