Data Manager customization: postFetchRecordsForGridListing

The postFetchRecordsForGridListing customization allows you to modify the result set that will be used to fill an object's record listing table. It receives objectName and records (query result set) in the args struct and is not expected to return a result.

This customization is run before the decorateRecordsForGridListing customization and appears to do the same thing. However, you can use this customization to make changes before using the core Data Manager implementation of decorateRecordsForGridListing that will add grid fields, checkboxes, etc. to the result set.

For example, here we use a fictional injected service to add values to each record that we may wish to use later (there would probably be a more efficient way to do this, but perhaps this could be the only way for you to achieve it):

// /application/handlers/admin/datamanager/blog_post.cfc

component {

	property name="myCustomSecurityService" inject="myCustomSecurityService";

	private void function postFetchRecordsForGridListing( event, rc, prc, args={} ) {
		var records = args.records ?: QueryNew( '' );
		var secureCol = [];

		for( var r in records ){
			secureCol.append( myCustomSecurityService.isSecure( ?: "" ) );

		QueryAddColumn( records, "isSecure", secureCol );
