Strapi CMS third level populating

Question

I have a problem with fetching third level data from Strapi CMS.

My Structure is the following:

Page > Content(Dynamic Zone) > Multiple Entitys e.g. HeroSliderElement.

So Calling this URL from Postman:

{{protocol}}://{{host}}:{{port}}/api/pages?populate[Content][populate]=*

But since inside my HeroSliderElement are images i have the problem, that i dont get these back.

There should be the media data linked from the CMS:

Does anyone have an Idea how to fix this? Any help is appreciated!

I am currently using the following versions of packages:

  "dependencies": {
"@strapi/plugin-i18n": "4.0.7",
"@strapi/plugin-users-permissions": "4.0.7",
"@strapi/provider-upload-aws-s3": "^4.1.0",
"@strapi/strapi": "4.0.7",
"pg": "8.6.0",
"strapi-provider-upload-aws-s3": "^3.6.8"

},

Answer 1

Install the official strapi plugin : strapi-plugin-populate-deep , its easy and great plugin for nested content structure, it worked for me.

Examples: Populate a request with the default max depth.

/api/articles?populate=deep

Populate a request with the a custom depth

/api/articles?populate=deep,10

Populate a request with the a custom depth

/api/articles/1?populate=deep,10

Whilst this plugin is great for ease of use, when building applications at scale, you don't want to be creating queries that simply grab everything. Also, you're likely to pull down something you don't want the public to see. In other words, please use it with caution. – Estimate

Yes, that comes with caution! So whoever is gonna use it please use it wisely. Thanks for your valuable advice. @DallasClark – Corriecorriedale

Just want to add context to anyone using populate deep plugin. Since it get all the data for the depth specified. It may lead to performance issues. I no longer use the plugin and handle filtering and populating natively to Strapi.

Answer 3

you need to specify every record(object, entity) at level three to fetch data from it. like as you said you want to fetch data of images from content from your this will work

{{protocol}}://{{host}}:{{port}}/api/pages?populate[Content][populate]=images

thank you for you answer. Unfortunately this does not fix my problem. The Content element is my "Zone" and one of the elements is the HeroSliderElement. And inside of the HeroSliderElement is Media. So I need to specify that the backend should return the media inside the HeroSliderElement inside the Content Zone inside the page. Do you have any idea? It would be awesome. – Sauveur

Did you end up having any luck with this? I'm facing the issue. – Wanderlust
