CKAN 2.9 ValueError:注册表初始化:：ckan基本图表插件

Question

我对克南很陌生。在成功安装了ckan之后，当我使用一些ckan插件作为示例后，我得到了ValueError。经过一些研究，我知道这与网络资产有关。在基本图表文件夹中，我将{%资源.}更改为{%资产.}

ckanext/basiccharts/theme/templates/basechart_view.html文件中的.html

但我还是会犯同样的错误。谁能解释一下这个错误背后的逻辑以及一些消除这个错误的技巧吗？

Answer 1

为了迁移到webasset，您需要创建一个资产文件夹，并将扩展名为.js和.css的文件放在那里。此外，您需要在资产文件夹中创建webassets.yml，其中应该注册这些.js和.css文件。这个过程被描述为这里和这里。

但是，您可以使用与当前的ckan版本兼容的ckanext-基本图表的这版本。
