このプロジェクトはライセンスの問題のため、オープンソース化できません。さらなる技術サポートとサービスについては、私の Knowledge Planet に参加してください。

1. DingTalk を模倣するプロセスを保存および表示するためのインターフェイスを作成する必要があります。まずテーブルを作成し、それをオンラインで使用してテーブルを作成します。

2. 上記のコードを生成し、対応するフロントエンド プロジェクトとバックエンド プロジェクトに配置します。

3. 次のように、フロントエンド模倣 DingTalk プロセスの設計機能を変更し、元のリスト ページにダイアログ ボックスを追加します。

<el-dialog :title="designerData.name" class="ddDialog" v-model="designerOpen" append-to-body fullscreen>
      <ding-designer
        ref="ddDesigner"
        v-loading="designerLoading"
        :process = "flowJsonData"
        @save="onSaveDesigner"
      />
    </el-dialog>

4.上記の模造釘打ち工程コンポーネントを追加
