[英]How to get specific field from nested table relation in adonisjs
这是我的代码查询
我只想从每个表中获取一些特定字段:
const project = await Project.query()
.where("user_id", user_id)
.where('id', project_id)
.with('items.file.sheets.markup.comment.attachment').first()
但我得到这个回应有很多额外的领域

但我不需要像每个表中的某些字段那样的 project_id 等
例如,我只需要文件表中的这些字段,并希望从查询中的每个表中获取特定字段,但我在 postman 中得到高于 output 响应
```
"id": 1,
"actual_name": "10 -Rehan Shakeel - Feb2021.pdf",
"image_url": "https://resolve-dev/file/2/1/1/1616588346705_117.pdf",
"media_type": "profile",
"created_at": "2021-03-24 17:19:05",
"updated_at": "2021-03-24 17:19:05",
"deleted_at": null,
```
尝试使用数组内的列添加 select 语句
const project = await Project.query()
.select(['tableyouwant.id', 'actual_name', 'image_url', 'media_type', ..........])
.where('id', project_id)
.with('items.file.sheets.markup.comment.attachment').first()
