joomlaコンポーネントを作成しました。管理者の公開ボタンと非公開ボタンをクリックすると、そのようなエラーが表示されます。

Fatal error: Call to a member function publish() on boolean in ...\libraries\legacy\controller\admin.php on line 209

Answer 1

あなたはgetModel()メソッドを使用して、コントローラにモデルを提供する必要があります。例えば、com_contentのarticles controllerを見てください。

Answer 2

あなたは内パブリッシュ機能付きテーブルファイルを追加する必要があります。私は、これはただで働くだろうことを保証することはできません、これはテーブルファイルのほんの一例であることに、注意してください

コピー&ペースト。別の例については、com_content/tableを確認してください。

また、あなたのリストに単品モデルgetTable（）を追加します。

public function getTable($type = 'view_name', $prefix = 'labTable', $config = array()) 
{ 
    return JTable::getInstance($type, $prefix, $config); 
} 

をファイル構造が正しいかどうか確認してください：
