did you check the documentation ? Populate and Select | Strapi Documentation

4

it should be something more like this GET /api/articles?populate[category][populate][0]=restaurants

5

yes i did and it nowhere specifies how to do what i need

6

this only populates restaurants under categories in articles

7

converting this to my case this would only populate the zestawy_cwiczens under grupy in user, but i also want all other relations that user has

8

you then need to add all your other relations in the url

9

/api/articles?populate[category][populate][0]=restaurants&populate=other

10

I use to write all the attributes with qs library in js, not on the url directly

11

it’s on the documentation too (qs - npm)

12

here ? Understanding populate | Strapi Documentation

13

populate[0]=relation-name&populate[1]=another-relation-name&populate[2]=yet-another-relation-name

14

yea i already done that, but i have to write all relations by hand - cant use the wildcard (*)

15

if you only put populate=* it doesn’t give you all the relations ?

16

If i put only this then it does

17

But i also need that 2 level deep relation

18

If you need to always do this for that service call, you can do an override on the controller of the find method(s) and write the code to retrieve the relations you need using the Entity Service API, which would be a lot more readable and manageable than the query string salad you’re going to have to put together for this

19

aha it is indeed a query string salad sometimes :sweat_smile:
