Widget for letting user add themself to a group

[felladin]

I have created a small widget that allows a user to add or remove themself from a group.

This is in large part borrowed from Create custom action buttons in Service Portal - ServicePortal.io - Service Portal, CMS, and Custom ...

The reason I add it to the community is that I found an interesting "feature" in ServiceNow that may confuse some.

When removing themselves from a group, regardless if this means changes in rolls and skills, the user will see the RoleManager Script Include info messages.

I fixed this by adding gs.flushMessages(); to the remove part.

Code for page:

<div class="panel panel-default">
<div class="panel-heading">Group membership</div>
<div class="panel-body">
 <button type="button" class="btn btn-primary btn-block" ng-click="c.uiAction('add')">Add me</button>
 <button type="button" class="btn btn-default btn-block" ng-click="c.uiAction('remove')">Remove me</button>
</div>
</div>

Code for Client:

function() {
   var c = this;
       c.uiAction = function(action) {
               c.data.action = action;
               c.server.update().then(function() {
                       c.data.action = undefined;
               })
       }
}

Code for server:

(function() {
       //Get user sys_id
       var me = gs.getUserID();
//If input from button, get which input
       if (input && input.action) {
               var action = input.action;
//If Add, check that user is not member and then add them
               if (action == 'add') {
                       var nydi = new GlideRecord('sys_user_grmember');
                       nydi.addQuery('user',me);
                       nydi.addQuery('group','sys_id of group');
                       nydi.query();
                       if(!nydi.next())
                       {
                               nydi.initialize();
                               nydi.user = me;
                               nydi.group = 'sys_id of group';
                               nydi.insert();
                               gs.addInfoMessage('You have been added to the group.');
                       }
               }
//If remove, check that user is member of the group then remove them.
               if (action == 'remove') {
                       var hardi = new GlideRecord('sys_user_grmember');
                       hardi.addQuery('user',me);
                       hardi.addQuery('group','sys_id of group');
                       hardi.query();
                       while(hardi.next())
                       {
                               hardi.deleteRecord();
                               gs.flushMessages();
                               gs.addInfoMessage('You are no longer a member of the group.');
                       }
               }
       }
})();
