Joined tables / nested objects with REST API

Hello,
I would like to know, if it is possible to use nested objects with REST API.
Let say, I have departments and each department shall read various documents.

Something like this:

[
   {
      "departmentID": 1, 
      "name": "Sales", 
      "documents": [
                      {
                       "docID":1, 
                       "name": "first_document"
                      }, 
                      {
                      "docID":2, 
                      "name": "second_document"
                      }, 
                   ]
}
]

When I get such object, I can’t work with that in the Department “Sales” in Forest Admin Frontend. I do not see in the detail of “Sales”, that “first_document” and “second_document” is applicable for this department.

If it is possible, could you please just refer me to a page clearing this?

I assume, that also this might work on a similar basis. Would it be please possible to provide me with a documentation, how this subsections for specific views are working?
I would like to know:

  1. if it is possible to try that out in free Forest Admin version.
  2. If it is possible to use that with REST API.

Hi again @Vaclav :wave: unfortunately relationships is not supported yet…
As Custom REST API is in beta many features are disabled.
Really sorry about that.
Apologie again.
