getCollectionEnumFieldItems

ts

function getCollectionEnumFieldItems(
   dataSourceProxy, 
   dataItemProxy, 
   fieldName): DataItemProxy[]

Extracts DataItemProxies from a collection enum field by field name/ID.

Key handling logic:

• For simple keys (single field primary key): Accepts single values or arrays of values
  • Single: fieldValues = 'user1'
  • Multiple: fieldValues = ['user1', 'user2']
• For composite keys (multi-field primary key): Uses schema detection to differentiate
  • Single composite: fieldValues = ['John', 'Smith']
  • Multiple composite: fieldValues = [['John', 'Smith'], ['Jane', 'Doe']]

Parameters

Parameter	Type	Description
dataSourceProxy	DataSourceProxy	The data source containing all collections
dataItemProxy	DataItemProxy	The data item to extract the field from
fieldName	string	The name/ID of the field to extract

Returns

DataItemProxy[]

Array of DataItemProxies from the first referenced collection, or empty array if not found
