  I think a

  beforeChange

  hook would work for that. Just check if the

  operation

  is

  create

  , then create a new document from the hook using payload's local api

  i was thinking to use afterChange though. The problem here is the syntax. I am not kinda familier with it. Where should i put what. If possible can you give me a simple example code solution ?

  Sure! afterChange would work as well! Make sure to check if the

  operation

  of the afterCheck is

  create

  in that case.

  
  

  Definitely check out the docs first:

  https://payloadcms.com/docs/hooks/collections#afterchange

  the first code example is how you could do it! So:

  
  
  

  import { CollectionConfig } from 'payload/types';
  
  export const YourCollection: CollectionConfig = {
    slug: 'yourslug',
    fields: [
      { name: 'name', type: 'text'},
    ],
    hooks: {
      afterChange: [({doc, operation}) => {
  
        if(operation === 'create') {
           // create document here
        }
  
      }],
    },
  }

  now let's say i have a collection called myCollection with two fields one is name, another is yourCollection which is relationTo this YourCollection. now i want to create myCollection afterCreating YourCollection.

  
  
  

  inshort what i meant is i need that syntax. where we are creating that.

  import { CollectionConfig } from 'payload/types';
  
  export const YourCollection: CollectionConfig = {
    slug: 'yourslug',
    fields: [
      { name: 'name', type: 'text'},
    ],
    hooks: {
      afterChange: [({doc, operation}) => {
  
        if(operation === 'create') {
           await payload.create({
              collection: 'myCollection',
              data: {
                yourCollection: doc.id,
                name: 'some text'
              },
          });
        }
  
      }],
    },
  }

  
  

  that should work! Just a simple payload.create call

  
  

  
  

  "yourCollection" would be the relationTo field

  
  

  
  

  Definitely also give

  https://payloadcms.com/docs/local-api/overview

  a read for the syntax for the payload local API (

  payload.create

  is part of it). Can do many other things as well, e.g. updating documents

  Great thanks it

  
  

  
  

  's

  
  

  
  

  working fine

  
  

  
  

  now if i want this field name: 'some text'

  
  

  to be dynamic like it will contain the name of this collection and some other text something like that. how can i achieve that ?

  You should be able to just use

  name: doc.title+'some text'

  or something like that, assuming you have a text field named

  title
  

  
  

  doc

  contains all the data of your current document after it has been created, so you have access to it all via that variable!
