Hi Guys,
I am starting with Strapi trying to create a small application. I wanted to list the articles of a logged in user without having to pass the query from the frontend. I thought about creating a middleware that takes the user id from the jwt. I get the id perfectly, but I don’t know how to incorporate the corresponding where to the request. can you help me?

Thanks in advance

Found an example in the forums

Used a middleware to set the author

github.com

msoler75/strapi4author/blob/master/src/middlewares/assign-owner.js

'use strict';

/**
 * `assign-owner` middleware.
 */

module.exports = (config, { strapi }) => {
  // Add your own logic here.
  return async (ctx, next) => {

    ctx.request.body.data.author = ctx.state.user.id
    
    await next();
  };
};

And a policy to mutate the queries

github.com

msoler75/strapi4author/blob/master/src/policies/is-owner.js

// the content type must have field named "author" that is a relation N-1 to users-permission
module.exports = async (policyContext, config, {
  strapi
}) => {
  const ctx = policyContext
  if (!ctx.state.isAuthenticated)
    return false
  const api = ctx.state.route.info.apiName 
  const controller = api // assume controller same as api name
  const service = strapi.service(`api::${api}.${controller}`)
  if (!service)
    return false
  if (!ctx.params.id) return true
  const {
    results: [content]
  } = await service.find({
    filters: {
      id: {
        $eq: ctx.params.id
      },
