How to hide or exclude fields in strapi query? - strapi

Question

I get all the properties in query, like even created_by,updated_by...
{
"client_ip": "Velit quo libero sun",
"verifier": "Voluptas ut sit sun",
"created_by": {
"id": 1,
"firstname": "admin",
"lastname": "admin",
"username": null
},
"updated_by": {
"id": 1,
"firstname": "admin",
"lastname": "admin",
"username": null
}}
Is there a way to remove these unwanted fields?

Answer 1

There are two thing you could do in the model and attributes validation
Use the private validation options on an attribute, to not return it in the default endpoints.
"attributes": {
"title": {
"type": "string",
"private": true
}
Check out the docs.
You can also disable the timestamps in your model, with:
{
"options": {
"timestamps": false
}
}
Check out the docs.
Something like the 2nd method, will soon be available for the created_by & updated_by attributes, it is a know issue since v3.1.x.

Answer 2

You can create a custom controller to reduce payload size or hide responses manually.
In your controller handler you can use the delete operator to remove unwanted props
Using optional chaining (?) (supported from Node.js version 14)
handlerName : async (ctx) => {
const results = await strapi.services?.["serviceName"]?.findOne() ?? {};
delete results?.created_by;
delete results?.updated_by;
ctx.send(results)
}

Answer 3

If you use strapi >= 4.0.0, you can provide privateAttributes to your model's options to exclude fields from both the admin panel and the response. https://docs.strapi.io/developer-docs/latest/development/backend-customization/models.html#model-options

Answer 4

if you dont want to show this attributes do this on model..
"options": {
"privateAttributes": [
"createdAt",
"updatedAt",
"publishedAt",
"createdBy",
"updatedBy"
]
and if you dont want to show your columns data Then do this.
await strapi.entityService.findMany('modelNAme', {
fields:['fieldName'] }.
