Unable to extend a core service?

Discord Q&A strapi-questions
1

I am having trouble getting my Controller to call a core find method for my fixture api. I followed the documentation correctly.


module.exports = createCoreController('api::fixture.fixture', ({ strapi }) => ({
    async find(...args) {
        console.log("hitting custom service")
        return await strapi.service('api::fixture.fixture').find(args);
    }
}))

const { createCoreService } = require('@strapi/strapi').factories;

module.exports = createCoreService('api::fixture.fixture'), ({ strapi }) => ({
    async find(...args) {
        console.log("hit me!")
        const {results, pagination} = await super.find(...args);
        return {results, pagination};
    },

});

After hitting http://localhost:1337/api/fixtures?populate=*, it does not interact with the “hit me!” log i created, therefore this service is not being invoked at all.

Any ideas?

Because you are over riding an existing service, you would construct your controller like this
const { createCoreController } = require(“@strapi/strapi”).factories;

module.exports = createCoreController(“api::fixture.fixture”, ({ strapi }) => ({
async find(ctx) {
// your custom logic for modifying the input
ctx.query = { …ctx.query, locale: “en” }; // force ctx.query.locale to ‘en’ regardless of what was requested

// Call the default parent controller action
const result = await super.find(ctx);
return result;

},
}));


And you service will look like the following.

"use strict";

/**
 * fixture service
 */

const { createCoreService } = require("@strapi/strapi").factories;

module.exports = createCoreService("api::fixture.fixture", ({ strapi }) => ({
  async find(...args) {
    console.log("hit me!");
    const { results, pagination } = await super.find(...args);
    return { results, pagination };
  },
}));

here is the repo of the working example. I used the following documentation Services | Strapi Documentation

repo: testing-service-and-controller-overide/src/api/fixture at main · PaulBratslavsky/testing-service-and-controller-overide · GitHub

This worked. And I go the console log.

Thanks very much Paul, so the controller was wrong I guess! Works a treat now :+1:t2:
