TypeORM Select Column from relation without using QueryBuilder

If anyway to select columns from relation without using querybuilder ???
This is my current query:
const areas = await this.areaRepository.find({
where: { ...isActive },
relations: ["division"],
});
Output :
{
"id": 1,
"version": 9,
"isActive": 1,
"createdBy": null,
"updatedBy": 1,
"createAt": "2022-04-18T15:42:12.000Z",
"updatedAt": "2022-09-23T11:04:53.000Z",
"name": "Dhaka",
"division": {
"id": 3,
"version": 1,
"isActive": 1,
"createdBy": null,
"updatedBy": null,
"createAt": "2022-04-18T15:42:00.000Z",
"updatedAt": "2022-04-18T15:42:00.000Z",
"name": "Dhaka"
}
},
But is there anything like:
const areas = await this.areaRepository.find({
select: ['id','division.id division_id']
where: { ...isActive },
relations: ["division"],
});
And the output will be:
{
"id": 1,
"division_id": 3
}

This is a duplicated question of: How to select fields from joined table using TypeORM repository?
You can check the answer here. Also this depends on which TypeOrm version you are currently using, as far as I know on version under 0.3 this doesn't work.

Accessing nested JSON object with JavaScript [duplicate]

This question already has answers here:
How can I access and process nested objects, arrays, or JSON?

Closed 4 months ago.
I am trying to access a nested JSON object and display it within the console.
Here is my JSON
{
"currentUser": {

"webp": "./images/avatars/image-juliusomo.webp"
},
"username": "juliusomo"

}
},
]
}
}
I am trying to access the reply by doing console.log(data.comments.replies); When i do this I get the following error in the console.
TypeError: comments.replies is undefined
Here is my code
fetch('./data.json', {
method: 'GET',
headers: {
'Accept': 'application/json',
},
})
.then((response) => response.json())
.then((data) => {
console.log(data.comments.replies);
})
.catch((error) => {
console.log(error);
});
I would like to loop over the array in order to display the information in html. I am un clear how to do this

Use index
data.comments[index].replies
Example:
data.comments[1].replies
const data = {
"currentUser": {
"image": {
"png": "./images/avatars/image-juliusomo.png",
"webp": "./images/avatars/image-juliusomo.webp"
},
"username": "juliusomo"
},
"comments": [{

I think you need to check the documentation for your API (if you use rest API) or schema of GraphQl playground (if you use GrapQl).
Install Swagger UI documentation plugin to check schema.
This may fix your problem.

Maybe this can give you some directions.
LINK TO STRAPI CONTENT API GET
and this is what this should return for you:

How can I get the created by and updated by fields in StrapiJS?

I've just started using StrapiJS, and it's really great so far, but now I've come across a problem.
When creating adding some data to the database, Strapi automatically creates some fields - like created_by and updated_by fields, but I'm not getting them in the API response.
This is the data stored in MongoDB:
{
"_id": {
"$oid": "606fd90b0057c05954d29f50"
},
"likes": 0,
"dislikes": 0,
"Title": "Why is this not working?",
"Subtitle": "I really don't know",
"slug": "why-is-this-not-working",
"content": "**I DO NOT KNOW**",
"published_at": {
"$date": "2021-04-09T04:33:17.304Z"
},
"createdAt": {
"$date": "2021-04-09T04:33:15.232Z"
},
"updatedAt": {
"$date": "2021-04-09T04:33:17.316Z"
},
"__v": 0,
"created_by": {
"$oid": "606f1a45af15265f780983ce"
},
"updated_by": {
"$oid": "606f1a45af15265f780983ce"
}
}
And this is the API response:
{
"likes": 0,
"dislikes": 0,
"_id": "606fd90b0057c05954d29f50",
"Title": "Why is this not working?",
"Subtitle": "I really don't know",
"slug": "why-is-this-not-working",
"content": "**I DO NOT KNOW**",
"published_at": "2021-04-09T04:33:17.304Z",
"createdAt": "2021-04-09T04:33:15.232Z",
"updatedAt": "2021-04-09T04:33:17.316Z",
"__v": 0,
"id": "606fd90b0057c05954d29f50"
}
Is there a way to get the created of the data in the API response?

You will have to override the findOne method in your controller like below without the sanitize:
async findOne(ctx) {
const { id } = ctx.params;
const entity = await strapi.services.blogPost.findOne({ id });
// return sanitizeEntity(entity, { model: strapi.models.blogPost});
return entity;
}
refer:Backend customization

set populateCreatorFields=true in model.settings.json

This seem to work for me
Add
"populateCreatorFields": true
Add Optional
"publicAttributes": ["created_at", "updated_by"]
to
api/blog-post/models/blog-post.settings.json
...
"options": {
"increments": true,
"timestamps": true,
"draftAndPublish": true,
"populateCreatorFields": true
}
...

Q1: What is this error ?
Q2: How to solve it?
P.S.: (Tested on Qt 5.2b & 5.1.1)

Bug was actually some missed debugging log in Qt. Upon creating Bugtrack issue problem was adressed and will be solved in next stable release (Qt 5.2.0).
