Kendo TreeList没有刷新平面数据

Question

我正在使用Kendo TreeList。我使用Django TreeBeard的Adjacency List数据结构在数据库中有一个数据结构。对于树形图，由于数据是嵌套的，我创建平面对象并将它们放入数组中。这很好用，但是treelist不会刷新数据。

对象结构与父对象结构相同，但子节点不显示。

这是我的代码。

JSON：PARENT NODE

{"id": 26, "tgtWeight": 0.0, "currWeight": 0.0, "hasChildnode": true, "ext_model_id": 8, "parent": null, "SSM": {"id": 8, "securitySelectionModelName": "ssm8", "userCreatedModel": "[{\"classificationName\":\"ssm8\",\"id\":8,\"hasChildNode\":true,\"child\":[{\"classificationName\":\"MBS\",\"id\":14,\"hasChildNode\":true,\"child\":[{\"classificationName\":\"Common Stock\",\"id\":15,\"hasChildNode\":false}]}]}]", "classificationNames": []}, "classificationNameNode": null}

JSON CHILD NODE

[{"id": 27, "tgtWeight": 0.0, "currWeight": 0.0, "hasChildnode": true, "ext_model_id": 14, "parent": {"id": 26, "tgtWeight": 0.0, "currWeight": 0.0, "hasChildnode": true, "ext_model_id": 8, "parent": null, "SSM": 8, "classificationNameNode": null}, "SSM": {"id": 8, "securitySelectionModelName": "ssm8", "userCreatedModel": "[{\"classificationName\":\"ssm8\",\"id\":8,\"hasChildNode\":true,\"child\":[{\"classificationName\":\"MBS\",\"id\":14,\"hasChildNode\":true,\"child\":[{\"classificationName\":\"Common Stock\",\"id\":15,\"hasChildNode\":false}]}]}]", "classificationNames": []}, "classificationNameNode": {"id": 14, "classificationLevel": 2, "classificationName": "MBS", "hasChildNode": false, "parent": 2}}]
