Breadcrumb navigation with Doctrine NestedSet

Question

I have a model that implements NestedSet behaviour:

Page:
  actAs:
    NestedSet:
      hasManyRoots: true
      rootColumnName: root_id
  columns:
    slug: str         


        

Answer 1

Since I hate having any kind of logic in templates (and partials), here's my slightly improved version.

//module/templates/_breadcrumbElement.php


  getName() ?>
  get('__children')) > 0): ?>
    

       $child->get('__children'), 'parent' => $child)) ?>
    
  

So, all the logic for building a url is now in Page::getPath() method.

class Page extends BasePage
{
  /**
   * Full path to node from root
   *
   */
  protected $path = false;

  public function __toString()
  {
    return $this->getSlug();
  }
  public function getPath($parent = null)
  {
    if (!$this->path)
    {
      $this->path = join('/', null !== $parent ? array($parent->getPath(), $this) : array($this));
    }
    return $this->path;
  } 
}

What I don't like it having to pass $parent to Page::getPath(). It just doesn't make any semantical sense.
