Use findOne for other parameters than id? about strapi

[iparker]

@benjamincanac Thanks for this hint. I changed the route to:

{
      "method": "GET",
      "path": "/articles/:slug",
      "handler": "article.findOne",
      "config": {
        "policies": []
      }

And with the following controller it works:

  async findOne (ctx) {
    const { slug } = ctx.params;

    const entity = await strapi.services.article.findOne({ slug });
    return sanitizeEntity(entity, { model: strapi.models.article });
  },

Thanks for your help!

Hi @iparker,

In order to do so, you have to override the controller of your findOne route:

async findOne (ctx) {
  await strapi.services.restaurant.findOne({ slug: ctx.params.slug })

  ...
}

Then you will be able to use the strapi module to call the route:

await this.$strapi.findOne('restaurants', '<slug>')

Thanks for your reply!

I tried the following code in controllers/article.js:

const { sanitizeEntity } = require('strapi-utils');
module.exports = {
  async findOne (ctx) {
    const { slug } = ctx.params;

    const entity = await strapi.services.article.findOne({ slug });
    return sanitizeEntity(entity, { model: strapi.models.article });
  },
};

But with this I get always a different result when I call this route for a slug, for example articles/my-slug.

I'm also wondering why it still "works" with an id. For the route articles/1 I also get differect articles for each request.

I don't know what's the mistake and how to solve this behaviour.

Спасибо за ответ!

Я попробовал следующий код в controllers / article.js:

const { sanitizeEntity } = require('strapi-utils');
module.exports = {
  async findOne (ctx) {
    const { slug } = ctx.params;

    const entity = await strapi.services.article.findOne({ slug });
    return sanitizeEntity(entity, { model: strapi.models.article });
  },
};

Но при этом я всегда получаю другой результат, когда вызываю этот маршрут для слага, например, article / my-slug.

Еще мне интересно, почему он до сих пор "работает" с id. Для статей маршрута / 1 я также получаю разные статьи по каждому запросу.

Я не знаю, в чем ошибка и как исправить такое поведение.

Hey! I made such a decision for myself, I hope it helps you
I decided not to override routes, but to create a new one
sorry for my bad english

1. Add Route

  {
    "method": "GET",
    "path": "/article/:url",
    "handler": "articles.one",
    "config": {
      "policies": []
    }
  },

---

2. Add Service

  module.exports = {
    /**
    * Promise to fetch record
    *
    * @return {Promise}
    */

    one(params) {
      return strapi.query('articles').findOne(params);
      // return params;
    },
  };

---

3. Add Controller

  'use strict';
  const { parseMultipartData, sanitizeEntity } = require('strapi-utils');

  module.exports = {
    /**
    * Retrieve a record.
    *
    * @return {Object}
    */

    one: async ctx => {
      const { url } = ctx.params;
      const entity = await strapi.services.articles.one({ url });
      // return sanitizeEntity(entity, { model: strapi.models.articles });
      return entity;
    },
  };

---

4. (optional) Add GraphQL
   4.1) create file schema.graphql.js in folder config

    const { sanitizeEntity } = require('strapi-utils');

    module.exports = {
      query: `
        articleByUrl(url: String name: String): Articles
      `,
      resolver: {
        Query: {
          articleByUrl: {
            resolverOf: 'Articles.one',
            async resolver(_, { url }) {
              const entity = await strapi.services.articles.one({ url });
              return sanitizeEntity(entity, { model: strapi.models.articles });
            },
          },
        },
      },
    };

Example query

    query ($url: String = "url") {
      articleByUrl(url: $url) {
        id
        title
        content
        created_at
        image {
          url
        }
      }
    }

@iparker Did you rename the :id to :slug in your route config? If you didn't, then slug is undefined and the findOne will return the first result.

One more short question to this: What is the right naming schema.

I want adapt this code to another model named article-category.

The folder name with the json is article-category.

I tried the following code to change the findOne:

const { sanitizeEntity } = require('strapi-utils');

module.exports = {

  async findOne (ctx) {
    const { slug } = ctx.params;

    const entity = await strapi.services.article-category.findOne({ slug });
    return sanitizeEntity(entity, { model: strapi.models.article-category });
  },
};

I tried different naming variants of the service but nothing worked for me. I always got an 500 internal server error when I call for GET article-catregories/slug.

Hope you can help me with this!

Best regards,

Timo
