时间:2022-07-20 15:24:48

How to create an entity with a parent using gcloud, datastore and nodejs?

如何使用gcloud,datastore和nodejs创建父级实体?

How to search for all the entities with a given parent?

如何搜索给定父级的所有实体?

Something like (this does not work):

像(这不起作用):

var path = [{kind: 'Parent', id: parentId}, {kind: 'Me'}];
var key = ds.key(path);
var entity = {
  key: key,
  data: toDatastore(data, ['description'])
};
ds.save(entity)

Reading the docs I did not find any example of creating an entity with a given parent. I searched (without success) here: https://googlecloudplatform.github.io/gcloud-node/#/docs/v0.19.1

阅读文档我没有找到任何创建具有给定父级的实体的示例。我在这里搜索(没有成功):https://googlecloudplatform.github.io/gcloud-node/#/docs/v0.19.1

while on the counterpart in python there are some specific proprieties to specify the parent entity: http://googlecloudplatform.github.io/gcloud-python/latest/datastore-keys.html

而在python中的对应物上有一些特定的属性来指定父实体:http://googlecloudplatform.github.io/gcloud-python/latest/datastore-keys.html

Please provide an example of code of how create and search for an entity with a parent

请提供有关如何使用父级创建和搜索实体的代码示例

I think you just want something like:

我想你只想要这样的东西:

var key = ds.key(['Parent', parentId, 'Me']);
