<h1>模块组织<a class="headerlink" href="#id5" title="Permalink to this headline">¶</a></h1>
<p>由于管理节点( node )注册到一个“树”,因此很容易地管理它们。:</p>
<div class="highlight-python"><pre>library = admin.register_node('/library', 'library', my library)
book_module = admin.register_module(BookModule, '/books', 'books',
    'book management', parent=library)</pre>
</div>
<p>为了满足你的需求,导航和面包屑会自动地建立。子模块的安全将会继承自父模块。</p>
