Make a findOne with id sent in url before a Guard

[hexed mountain]

Hi I would like to know if it's possible to make a findOne or to call an action from the service with a decorator to have the full entity with the id from the url and then to give it to a guard for permission. I let you screen so you can understand what I want to do more clearly

Suggestion for @hexed mountain:
:warning: Please do not screenshot code as it causes a number of issues:

• Ease of assistance: if someone wants to copy your code and correct it, they cannot. Making it easy for people to help you is in your best interests.
• Editorializing: it's common to try to make images small, which means you're likely to crop out code relevant to your issue
• Accessibility: wide images can be hard to read on mobile devices, and are impossible for screen readers.
• Legibility: you cannot read screenshots of code directly, instead you have to open them in an enlarged context.
• Bandwidth usage/clutter: some of our members use metered connections, and it is wasteful for them to download images of a text.

For a small amount of code, please use a code-block.

If one day that can help someone I found this solution:

import { CanActivate, ExecutionContext, Injectable } from '@nestjs/common'
import { WorkTimesService } from './work-times.service'

/**
 * @description This guard is used to check if the current userLinkId has a work time in progress and then to get it so we can check if the user have access to this work time
 * @date 11/04/2024 - 12:57:05
 *
 * @export
 * @class CurrentWorkTimeGuard
 * @typedef {CurrentWorkTimeGuard}
 * @implements {CanActivate}
 */

@Injectable()
export class CurrentWorkTimeGuard implements CanActivate {
    constructor(private _workTimesService: WorkTimesService) {}

    async canActivate(context: ExecutionContext): Promise<boolean> {
        const request = context.switchToHttp().getRequest()
        const { userLinkId } = request.params
        const workTime =
            await this._workTimesService.getCurrentWorkTime(userLinkId)

        if (!workTime) {
            return false
        }
        request.params.workTimeId = workTime.id
        return true
    }
}
