如何仅使用模型在 cakephp 中创建导航？

标题说明了一切。我将拥有如下所示的导航，它是从数据库动态创建的。

<ul>
    <li><a href='controller/view/1'>1</li>
    <li><a href='controller/view/2'>2</li>
    <li><a href='controller/view/3'>3</li>
</ul>

除活动页面外，每个页面上的内容都应该相同（逐页，我的意思是每个控制器上）。这是我第一次使用 cakephp。

这是我的元素文件：

<ul id="left-navigation">
<?php
App::import('Model','Godina');
$navigacija = $this->Godina->find('all');
foreach($navigacija as $nav){
echo '<li>' . $this->html->link($nav['Godina']      ['godina'],array('controller'=>'godina','action'=>'program',$nav['Godina']['godina'])
) . '</li>';
}

?>

这就是我收到的错误。

Fatal error: Call to a member function find() on a non-object in     /Applications/MAMP/htdocs/cakephp/app/View/Elements/godineNavigacija.ctp on line 4

由于我对 cakephp 核心的了解很低，所以它不起作用。谢谢。

Title says all. I'll have navigation that looks like this and it's dynamically created from database.

<ul>
    <li><a href='controller/view/1'>1</li>
    <li><a href='controller/view/2'>2</li>
    <li><a href='controller/view/3'>3</li>
</ul>

It should be same on every page (by page, I mean on every controller), except for the active one. It's my first time in cakephp.

This is my elements file:

<ul id="left-navigation">
<?php
App::import('Model','Godina');
$navigacija = $this->Godina->find('all');
foreach($navigacija as $nav){
echo '<li>' . $this->html->link($nav['Godina']      ['godina'],array('controller'=>'godina','action'=>'program',$nav['Godina']['godina'])
) . '</li>';
}

?>

And this is the error that I am getting.

Fatal error: Call to a member function find() on a non-object in     /Applications/MAMP/htdocs/cakephp/app/View/Elements/godineNavigacija.ctp on line 4

And since my knowledge of cakephp core is quite low, it just doesn't work.
Thanks.

App::import 只是加载文件，就像 PHP 的 include 一样，它不会实例化对象。所以 $this->Godina 不存在。您可以这样做：

$Godina = ClassRegistry::init('Godina');
$Godina->find(...);

为了正确的 MVC 分离，您不应该在视图中使用模型。您可以在 AppController::beforeFilter 中获取并设置数据，因此它会在每个页面上执行此操作，然后在视图中输出。或者，查看 requestAction。

App::import just loads the file, like PHP's include, it does not instantiate an object. So $this->Godina does not exist. You can do this:

$Godina = ClassRegistry::init('Godina');
$Godina->find(...);

For proper MVC separation, you should not use models in the view though. You can fetch and set the data in AppController::beforeFilter, so it does it on every page, then output in the view. Alternatively, look into requestAction.
