I have a list - Documents (Actually document library). I have given it two types of content types :- Document(default) & MyDocumentContentType (this is my custom content type)

Now Content Type Document have Title as Required field. And Content Type MyDocument have a custom col as required field - "MyRequiredField"

Now I want to fetch all the fields for list Documents, which have required property merged from all the content types.

Currently -> I get only Title as Required Field.

I want -> Title and MyRequiredField both as Required Fields.

I know I can fetch Fields for perticular content type by using ..../ContentTypes(ID)/Fields.

But it will give me fields for that particular content type.

Currently I have only option is to iterate over all the content types associated with a list and fetch fields for each, and then merge required flag in code.

But it will take 4 ajax calls if I have 3 content types associated with the list.

  • Is MyRequiredField site column or list column?? – Ganesh Sanap Jan 29 at 8:04

You could use batch rest api to reduce request to server.

Sample body.

--batch_e3b6819b-13c3-43bb-85b2-24b14122fed1
Content-Type: application/http
Content-Transfer-Encoding: binary
