循环关系不填充对象ID数组

工作流核心 , 工作流步骤 '

Workflow core有一个数组类型的步骤属性,它包含1个多步骤。打电话时上车 工作流核心 响应体没有用实际的步骤对象填充步骤数组。

{
"name": "workflow-core",
"base": "PersistedModel",
"idInjection": true,
"options": {
  "validateUpsert": true
},
"injectOptionsFromRemoteContext": true,
"properties": {
  "name": {
    "type": "string",
    "required": true,
    "default": "Untitled"
  },
  "user_id": {
    "type": "string",
    "required": false
  },
  "steps": {
    "type": "array",
    "required": false,
    "default": []
  }
},
"validations": [],
"relations": {
  "steps": {
    "model": "workflow-step",
    "type": "embedsMany"
  }
},
"acls": [
  {
    "accessType": "*",
    "principalType": "ROLE",
    "principalId": "$unauthenticated",
    "permission": "DENY"
  }
],
"methods": {}
}

工作流-step.json:

{
"name": "workflow-step",
"base": "PersistedModel",
"idInjection": true,
"options": {
  "validateUpsert": true
},
"properties": {
  "name": {
    "type": "string",
    "required": true,
    "default": "Untitled Step"
  },
  "status": {
    "type": "string",
    "default": "waiting"
  }
},
"validations": [],
"relations": {},
"acls": [],
"methods": {}
}

{
  "name": "Untitled",
  "user_id": "string",
  "steps": [],
  "id": "string",
  "workflow-steps": [
    {
      "name": "Untitled Step",
      "status": "waiting",
      "id": "string"
    }
  ]
}

我得到的是:

{
    "name": "Updated with step",
    "user_id": "231569461654",
    "id": "5b75bc769b3143103cb787c2",
    "workflow-steps": [],
    "steps": [
      "5b760fff24ccc23934fef240"
    ]
  }

hasMany似乎做了相同的事情,只是响应体中没有工作流步骤数组属性

这最终成为一个简单的解决方案:

我更改了workflow-core.json中的步骤关系:

"relations": {
    "steps": {
       "type": "hasMany",  <-- used hasMany instead of embedsMany
       "model": "WorkflowStep",
       "foreignKey": ""
     }
},
