Node Permission Directive

The NodePermissionDirective allows you to disable an HTML element or Angular component by taking a collection of the MinimalNodeEntity instances and checking the particular permission.

The decorated element will be disabled if:

  • there are no nodes in the collection
  • at least one of the nodes has no expected permission

Basic example

The best example to show NodePermissionDirective in action is by binding DocumentList selection property to a toolbar button.

For example the "Delete" button should be disabled if no selection is present or if user has no rights to delete at least one node in the selection.

<adf-toolbar title="toolbar example">
    <button md-icon-button
            adf-node-permission="delete"
            [adf-nodes]="documentList.selection">
        <md-icon>delete</md-icon>
    </button>
</adf-toolbar>

<adf-document-list #documentList ...>
 ...
</adf-document-list>

The button will become disabled by default, and is going to change its state once user selects/unselects one or multiple documents that current user has permission to delete.
