Plone 5.0 和 Carousel 2.2.1

Question

这个问题是关于 Plone 5.0 和附加 Carousel 2.2.1。 Carousel 的版本，取自 /usr/local/Plone/buildout-cache/eggs/Products.Carousel-2.2.1-py2.7.egg/EGG-INFO，是：

Metadata-Version: 1.1
Name: Products.Carousel
Version: 2.2.1
Summary: Carousel allows you to add user-configurable rotating banners to any section of a Plone site.
Home-page: <https://github.com/collective/Products.Carousel>
Author: Groundwire

下面显示了尝试在前台启动 Plone 的结果。 Plone 开始到一定程度，然后由于 Carousel 的问题而崩溃。显示输出的开始和结束；输出中间的许多诊断被省略了。

在 /usr/local/Plone-5.0/buildout-cache/eggs/Products.Carousel-2.2.1-py2.7.egg/Products/Carousel/browser/configure.zcml 第 24 到 31 行是：

<browser:viewlet  
    name="plone.contentactions"  
    for="Products.Carousel.interfaces.ICarouselFolder"  
    view="..interfaces.ICarouselSettingsView"  
    manager="plone.app.layout.viewlets.interfaces.IContentViews"  
    class="plone.app.layout.viewlets.common.ContentActionsViewlet"  
    permission="zope2.View"  
    />  

什么是 ContentActionsViewlet？我可以通过某种方式安装一个全局 ContentActionsViewlet 来解决这个问题，还是 Carousel 附加组件作者最好能够解决这个问题？这个相同的 Carousel 插件适用于 Plone 4.3.2。谢谢。

Answer 1

插件根本不兼容 Plone 5。

ContentActionsViewlet 被合并到 ContentViewsViewlet See plone.app.layout 2.5.8

很遗憾，这不是唯一的问题。

你需要联系维护者，可能他们愿意升级包，或者你可以自己尝试：

• Plone 5 升级指南：http://docs.plone.org/develop/addons/upgrade_to_50.html
• 包的好例子，它支持Plone 4.3.x和Plone 5 --> https://github.com/plone/plone.app.mosaic
