mooc7 devel_node_access.module _devel_node_access_nar_alter(&$grants, $node)

Helper function to mimic hook_node_access_records_alter() and trace what each module does with it.


object $grants: An indexed array of grant records, augmented by the '#module' key, as created by _devel_node_access_module_invoke_all('node_access_records'). This array is updated by the hook_node_access_records_alter() implementations.

$node: The node that the grant records belong to.

Return value

A tree representation of the grant records in $grants including their history: $data[$realm][$gid] ['original'] - grant record before processing ['current'] - grant record after processing (if still present) ['changes'][]['op'] - change message (add/change/delete by $module) ['grant'] - grant record after change (unless deleted)

This module gives developers feedback as to what their node_access table contains, and which nodes are protected or visible to the public.
