[UPDATE OUTDATED CONTENT] Understanding and Using Relations in Strapi

[Theodore-Kelechukwu-Onyejiaku]

Hi @miracleonyenma, thank you for your contribution to the "Write for the Community" program.

Content Issue

We would love to have an article update on "Understanding and Using Relations in Strapi". The main issue is that it lacks a detailed explanation, as shared by the documentation team.

"I have seen multiple instances where something gets mentioned near the start of the article, but then the article fails to go into a detailed explanation. For example: https://strapi.io/blog/everything-you-need-to-know-about-content-modeling This article mentions "Hierarchical Content Models" but doesn't explain how to approach them in Strapi. https://strapi.io/blog/understanding-and-using-relations-in-strapi This article mentions polymorphic relationships, but doesn't explain how to create them."

This means we will have to try as much as possible to explain and implement them with detailed explanations. If not, please don't list them.

Assignment

Please kindly update this article to include "polymorphic relationships" and how to create them in Strapi 5.

Please let me know if you are willing to do this. Thank you!

Hi @Theodore-Kelechukwu-Onyejiaku 👋,

Just finished making the update!

I added a clearer explanation of polymorphic relationships and included an example showing how to create one by directly modifying the Strapi schema file — located at:
./src/api/[content-type-name]/content-types/[content-type-name]/schema.json

Since this can’t currently be done via the admin dashboard, the example should help clarify things.

I also updated the example code so that they can check out the updated schema here:

Let me know if you have any questions or need further clarification. Thanks!
