php - 在 MVC 应用程序中生成路由的最佳位置在哪里？

Question

假设您有以下场景:

In you application, you have several models that are "Commentable". Comments are shown inan identical manner and can thus utilize the same template. In the default view of thecomments widget, the two most recent comments are shown, with a link to load remaining Xcomments.

The widget also have a form (i.e textarea that submits on enter-key) for adding a newcomment to the model.

鉴于上述要求，哪里是生成表单和加载链接完成其工作所需的链接的合理位置？

是否应该在调用模板的 View 中生成链接以及 Commentable 模型？即

<?php
  echo $this->partial('path/to/template/comments.phtml', array (
    'add-link' => $this->url($params, $routeName),
    'load-link' => $this->url($params, $routeName),
    'comments' => $this->model->getComments()
  );

向 Commentable 询问这些链接是否完全可以接受？即在 comments.phtml-template 中:

<div class="comments">
  <div class="loadLink">
    <a href="<?php echo $this->comments->getLoadLink() ?>">
       <?php echo sprintf('Show all %d comments', count($this->comments)); ?>
    </a>
  </div>
  <div class="container">
    <?php 
       foreach ($this->comments->getFirst(2) as $comment) {
          echo $this->partial('comment.phtml', array('comment' => $comment);
       }
    ?>      
  </div>
  <div class="addComment">
     <form action="<?php echo $this->comments->getAddLink() ?>" method="post">
       <div>
          <textarea class="autogrow" name="comment" 
                    placeholder="Write a new comment" rows="1" cols="80">
          </textarea>
       </div>
     </form>
  </div>
</div>

既然 MVC 提倡 View 可以与 Controller 通信，路由生成是否被视为与 Controller “通信”的一种方式，即使它不是以对象到对象的方式这样做？

在 MVC 应用程序中，您永远不应要求模型构建链接。您应该添加一些可以使用该模型生成这些链接的 View 助手。
