Question

在CKAN中，我尝试将所有数据集设置为“私有”，因此只有特定用户才能发布数据集。我创建了一个扩展并实现了IPackageController方法after_update - 如果需要，这将再次调用package_update将数据集设置为private：

class SetStateForPendingValidationPlugin(plugins.SingletonPlugin):
   plugins.implements(plugins.IPackageController, inherit=True)

   def after_update(self, context, data_dict):
    log.debug("CKAN after_update context: %r", context)
    log.debug("CKAN after_update data_dict: %r", data_dict)

    # Check if the user is the one who is allowed to publish datasets 

    # Only do this for active datasets, and not ones in draft or deleted state
    # it is also not needed if the dataset is already private
    if 'state' not in data_dict or ( 'state' in data_dict and data_dict['state'] == 'active'):
        if 'private' not in data_dict or ( 'private' in data_dict and data_dict['private'] == False):
            data_dict['private'] = True
            log.info("CKAN to send %r: ", data_dict)
            toolkit.get_action('package_update')(context, data_dict)

不幸的是，在启用FileStore的情况下执行此操作会导致网站崩溃，并且该用户不是管理员。数据集已正确保存，但系统在保存后尝试加载页面时会抱怨。它似乎与文件有关，因为当以管理员身份查看数据集时，似乎没有资源，并且作为普通用户，系统崩溃。

我已经使用IAuthFunction扩展了插件，它总是授予用户resource_create，然后它会停止崩溃。但文件/资源仍然不可见。

这似乎只在创建数据集时才有意义。之后添加资源/文件似乎按预期工作。

CKAN在扩展IPackageController after_update中使包变为私有
