Laravel用だけどPythonです。
Laravel5.8, Python3.7.4 で動作確認済み。Python２系だと文字化けするかも。
用意
- in: database.md
- DB情報をmarkdown形式で書く
- out: migrations/
- フォルダを作っておく
作成例)
database.md
## users
- ユーザ情報
| 名前 | データ型 | 照合順序 | 属性 | NULL | デフォルト値 | コメント | その他 |
|-----------------|--------------|--------------------|----------|------|--------------|----------|--------|
| id | bigint(20) | | UNSIGNED | no | なし | ID | AUTO_INCREMENT |
| email | varchar(255) | utf8mb4_unicode_ci | | no | なし | メールアドレス | UNIQUE |
| name | varchar(63) | utf8mb4_unicode_ci | | no | なし | 名前 |
| password | varchar(255) | utf8mb4_unicode_ci | | no | なし | ログインパスワード(暗号化) |
| last_logined_at | timestamp | | | yes | NULL | 最終ログイン日時 |
| remember_token | varchar(100) | utf8mb4_unicode_ci | | yes | NULL | パスワード再発行トークン |
| created_at | timestamp | | | yes | NULL | 作成日 |
| updated_at | timestamp | | | yes | NULL | 更新日 |
| deleted_at | timestamp | | | yes | NULL | 削除日 |
- テーブル名は見出しh２, スネークケース (## xxx_xxx)
- カラム情報のヘッダは 名前, データ型, 照合順序, 属性, NULL, デフォルト値, コメント, その他 の順
