python - Django CMS Aldryn 创建向导数据库错误

Question

我正在使用 Aldryn 新闻博客和常见问题解答插件。 Django 版本 1.8.8，Django CMS 3.2.0。

我正在尝试按工具栏中的“创建”来创建新的博客文章或常见问题解答问题(图 1)。

它会弹出一个很好的向导来填写内容，但是当我实际提交它时，我得到了图像2中的错误:

“/cms_wizard/create/处出现数据库错误使用 update_fields 保存不会影响任何行。”。

但是，它可以通过主管理区域正常工作，并且通过向导添加“新常见问题解答类别”也可以正常工作。

有什么想法吗？

Answer 1

比较 Aldryn FAQ(适用于您)和 Aldryn NewsBlog(不适用于您)的 CMSWizard 的 save() 方法，有一条线索:也许您已经设置了 WIZARD_CONTENT_PLUGIN 和 WIZARD_CONTENT_PLUGIN_BODY 设置？ FAQ 使用这些设置，而 NewsBlog 则不使用，而是需要使用 djangocms-text-ckeditor 的 TextPlugin。

我确实看到您安装了djangocms-text-ckeditor。我想知道您是否还没有为其运行迁移？

您可以在项目的其他地方使用普通的 TextPlugin 吗？
