loopback4

Question

我正在为环回 4 中关系的 openapi 规范映射而苦苦挣扎。

有两个实体：Plan 和 PlanItem 与 "Plan hasMany PlanItems" 相关在我的端点规范中，我已经声明包含这样的关系：

  @authenticate('jwt')
  @get('/{id}', {
    responses: {
      '200': {
        description: 'Plan for given id, including items',
        content: {
          'application/json': {
            schema: getModelSchemaRef(Plan, {
              title: "PlanWithRelations",
              exclude: ['ownerId'],
              includeRelations: true
            })
          },
        },
      },
    },
  })
  async findOne(
    @param.path.string('id') id: string,
  ): Promise<Plan | null> {
    return this.plansService.findOne(id);
  }

openapi.json 中的结果组件部分如下所示：

{
  "openapi": "3.0.0",
  "info": {
    "title": "ngbm-api - NGBM API v1.0",
    "version": "1.0.0",
    "contact": {

    }
  },
  // ...
  "components": {
    "schemas": {
      // ...
      "PlanWithRelations": {
        "title": "PlanWithRelations",
        "description": "(Schema options: { title: 'PlanWithRelations', exclude: [ 'ownerId' ], includeRelations: true })",
        "properties": {
          "id": {
            "type": "string"
          },
          "name": {
            "type": "string"
          },
          "items": {
            "type": "array",
            "items": {
              "$ref": "#/components/schemas/PlanWithRelations"
            }
          }
        },
        "required": [
          "name"
        ],
        "additionalProperties": false
      },
    }
  }
}

如您所见，'PlanWithRelations' 中的项目数组有一个指向相同模式 'PlanWithRelations' 而不是 'PlanItem'

的 $ref

有人可以提示我如何解决这个问题吗？如果您需要更多信息，请随时给我提示。

Answer 1

包含 "title" 会导致生成无效架构的已知错误。

解决方法是从 getModelSchemaRef 中删除 "title" 键：

schema: getModelSchemaRef(Plan, {
  exclude: ['ownerId'],
  includeRelations: true
})

PR with the fix 已合并，修复将很快发布。
