CakePHP中的动态布局 [英] Dynamic layouts in CakePHP

问题描述

对于问题标题很抱歉，但我找不到更适当的方式来表达这个问题。

Sorry about the question title, but I couldn't find a more appropriate way to phrase this.

我目前正在建立一个CakePHP网站，不太确定如何解决以下问题。网站看起来像下面的模型：

I am currently building a CakePHP powered website and I'm not quite sure how to approach the following issue. The website looks something like the follwing mockup:

。

灰色区域是布局的一部分，因为它们的内容在视图之间不会改变。在侧栏中，我有一组与多个模型相关联的广告。我需要控制器逻辑来确定与广告相关联的图片。此外，广告列表需要是动态的。我应该把构建边栏的逻辑放在哪里？

The greyed out areas are part of the layout, because their content does not change between views. In the sidebar, I have a collection of ads who are linked to several models. I need controller logic to determine the picture associated with an ad. Also, the ad list needs to be dynamic. Where should I put the logic for building the sidebar?

我想过：

• 将逻辑放入 AppController （ beforeFilter / afterFilter ） - 问题是， t使用控制器逻辑我需要（其他控制器继承自 AppController ，我不知道如何使用它们）。




• 在渲染视图的所有控制器中复制侧边栏代码 - 这似乎对我很蠢。

• putting the logic into the AppController (beforeFilter / afterFilter) - the problem is I can't use the controller logic I need (the other controllers inherit from AppController, I'm not sure how to use them there).
• making a component - is it okay to build components that rely on controllers?
• replicating the sidebar code in all controllers that render views - this seems kind of stupid to me.

经过一些阅读和实验，我已经重构了大部分内容。

After some reading and experimenting, I've gotten to refactoring most of it.

通过移动在模型中构建我的广告的逻辑（删除检索图片的组件），而不是使用 requestAction ，我获得了最佳性能。它几乎快了三倍，代码看起来好多了。

I obtained the best performance by moving the logic for building my ads in the model (eliminating the component that retrieved the pictures) and not using requestAction. It's almost three times faster and the code looks much better.

推荐答案

我做了类似的数据驱动导航。我把我的逻辑在 AppController :: beforeRender ，没有任何问题。我不知道我理解你关心的控制器继承的关注。我通过以下方式检索我的菜单：

I've done something similar for data-driven navigation. I put my logic in AppController::beforeRender and haven't had any problems. I'm not sure I understand your concern related to controller inheritance. I retrieve my menus via:

$menus = $this->NavMenuItem->groupByMenu();
$this->set( compact( 'menus' ) );

然后我创建了一个渲染菜单的元素。它由布局执行：

I then created an element that renders the menu. It's executed by the layout via:

<?php echo $this->element( 'navigation', array( 'id' => 'secondary', 'menu' => $menus['SECONDARY'] ) ) ?>

如果这没有帮助，也许你可以在注释中进一步解释控制器继承的问题。

If that doesn't help, maybe you can further explain your issue with controller inheritance in a comment.
