もうちょい改造して
$this->render('db:layout_index');のときだけdbを見に行くようにしたい- 先にdbを見に行って該当がなければファイルを参照したい
- elementsもdb保存したい
改造
- d4-1977氏のは1.2用で1.3では$this->Html->が動かんかった
- 1.3のviewをオーバーライドする方法で改造する
app/views/dbtemplate.php
- とりあえずうごくようにしただけで根本的に理解してない
- //parent::__construct();
- //$name = $this->viewPath . DS . $subDir . Inflector::underscore($name);
- cakephpの動作の仕組みやらオブジェクトの扱い方など勉強しなきゃ
- eval使ってるのでセキュリティに注意
