Django CMS菜单上的语言：类型'type'的对象没有len（）

Question

我最近在我的项目中加入了英文和简体中文。但是，当我更改为我的（已发布的）中文页面时，它会在使用show_menu时抛出TypeError。葡萄牙语和英语也不会发生同样的情况

TypeError at /zh-cn/
object of type 'type' has no len()
Request Method: GET
Request URL:    http://localhost:8000/zh-cn/
Django Version: 1.5.8
Exception Type: TypeError
Exception Value:    
object of type 'type' has no len()
Exception Location: /home/marcos/django/project/env/local/lib/python2.7/site-packages/menus/menu_pool.py in _mark_selected, line 171
Python Executable:  /home/marcos/django/project/env/bin/python

我做错了什么？

版本

Django 1.5.8

Django CMS 2.4.3

settings.py

LANGUAGES = (('pt', u'Português'), ('en', u'English'), ('zh-cn', u'中文'),)
CMS_LANGUAGES = LANGUAGES

base.html文件

{% load sekizai_tags i18n cms_tags menu_tags %}
(...)
<div class="nav top-nav">
    <ul class="inner-nav">
    {% show_menu 0 %}
    </ul>
</div>

Answer 1

今天在回顾我在项目的github上创建错误的步骤时，我找到了问题的根源。

当项目只有一种语言时，会在多个页面中挂起一些 apphooks 。我去了那些页面，保存并发布了草稿版本，它确实有效！

简而言之：

1. 识别出已经被禁止的页面
2. 点击＆＃34;保存并继续编辑＆＃34;，然后＆＃34;发布草稿＆＃34;每个
3. 重新启动服务器

我希望这有助于某人。

干杯并感谢您的帮助！
