Name: Restrict View by Role

Type: System UI > View Rules

Table: Any

Description: Generally the view used on a form is controlled by either specifying the sysparm_view parameter in the url or module properties, or by inheriting the view from the previous form or list. Sometimes this does not apply, such as when opening a referenced field form from a record producer. In this case, you may want to control the view of the form based on roles. This script assumes there is a view called ess available to the current table.

Parameters:

• view - A string containing the name of the current view.
• is_list - A Boolean value indicating whether this is a list view.

Script:

(function overrideView(view, is_list) {
//Force non-itil users to use the ess view
if (gs.hasRole("itil"))
{return;}
if (view.startsWith("ess"))
{return;}
// do not change view if it starts with sys_ (e.g. sys_ref_list)
if (view.startsWith("sys_"))
{return;}
answer = "ess"; // set the new view to answer
})(view, is_list);
