  They are prefilled here.

  
  
  

  Said that, I'm not sure is your use-case but I want to choose the parent only when creating outside JOIN Field.

  
  

  So I've created a custom component:

  
  
  

  {
    name: 'name',
    relationTo: 'slug',
    label: 'Label',  
    type: 'relationship',
    hasMany: false,
    maxDepth: 2,
    required: true,
    admin: {
      allowCreate: false,
      allowEdit: false,
      components: {
        Field: '@components/(payload)/fields/relationship/create-only',
      }
    },
    access: {
      create: () => true,
      update: () => false,
    },
  }

  
  
  

  Field component

  create-only.tsx
  

  'use client'
  
  import { RelationshipField, useDocumentInfo, useEditDepth } from '@payloadcms/ui'
  import { mergeObjects } from '@utils/collections'
  import type { RelationshipFieldClientComponent } from 'payload'
  
  const RelationshipCreateOnlyField: RelationshipFieldClientComponent = (props) => {
    const editDepth = useEditDepth();
    const { isEditing } = useDocumentInfo();
  
    const creatingOnTopLevel = ! isEditing && editDepth === 1;
    const className = creatingOnTopLevel ? 'relationship-create-only-field' : 'relationship-create-only-field read-only-relationship';
  
    props = mergeObjects(props, {readOnly: ! creatingOnTopLevel});
    props = mergeObjects(props, {field: { admin: { className: `${(props.field.admin?.className || '')} ${className}` } }});
  
    return <RelationshipField {...props} />
  }
  
  export default RelationshipCreateOnlyField;

  
  
  

  (mergeObject is only a personal util to merge configs)

  Oh yeah, it is already prefilled. I didn't realize I was looking at a field that was missing a step in the workflow.

  
  
  

  I have a client with drug test results. The drug test collection is joined to the client. That relationship field is prefilled. That drug test collection has a relationship field of my private-media collection. It's only there where the relationship field is not prefilled with the client.

  
  
  

  Hopefully that makes sense. I think the relationship field in the private-media collection is necessary because it uploads to S3 and is only accessible via presigned urls allowed by access control
