business rule

[Jeff W NZAO B]

Hi all,

I have create a BR 'cause I want to controle on my catalog it an application from the table Application has a true statut for its purchase. Purchase which is a column from the table Application

Here is my code, I'm not sure it's the best practice, I've tried Client script and script from UI Policy but found no solution.

(function executeRule(current, previous /*null when async*/) {
    // Check the condition: If u_purchase_licence is 'true', set display to true
	var application = g_form.getValue('appl_request_access_choice');
    if (current.u_purchase_licence === 'false' || application === '') {
        //g_form.setDisplay('alert_application', false);
		gs.addInfoMessage('Business Rule is running for CI Application: ' + current.name);
    } else {
        // If the condition is not met, you can hide the field (optional)
        //g_form.setDisplay('alert_application', true);
		gs.addInfoMessage('Business Rule is running for CI Application: ' + current.name);
    }
})(current, previous);

Table Application

Thanks for your feedback

You cannot control field visibility with a Business Rule.  Use a Client Script or UI Policy.  Neither will hide the field on a List view, only the form/record view.  If you want to control access on a list view you can try to create a read ACL for this field and table.

The following code is a client side code which will not work in a server side business rule script. 

g_form.getValue('appl_request_access_choice');

if appl_request_access_choice is a field available on form then it can be accessed in the server side as follows

current.getValue('appl_request_access_choice');

Hope this helps.

can you try this ?

--------------script include--------------------

getApplicationDetails: function() {

var id = this.getParameter('sysparm_userID');
var grBusapp = new GlideRecord('cmdb_ci_app');
grBusapp.addQuery('sys_id', id);
grBusapp.query();

var AppObj = {};
while (grBusapp.next()) {
AppObj.license = grBusapp.u_purchase_licence.toString();
AppObj.app = grBusapp.application.toString();
}
return JSON.stringify(AppObj);
},

-----------Onload--------------------

function onLoad() {
//Type appropriate comment here, and begin script below
var application = g_form.getValue('appl_request_access_choice');
var ga = new GlideAjax(" script inc Name"); 
ga.addParam("sysparm_name", "getApplicationDetails");
ga.addParam("sysparm_ID", application);
ga.getXML(userDet);
}

function userDet(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
var res = JSON.parse(answer);

var app = res.application;

var license = res.u_purchase_licence;

if (license == 'false' || application == '') {
g_form.setDisplay('alert_application', false);
} else {
// If the condition is not met, you can hide the field (optional)
g_form.setDisplay('alert_application', true);
}

let me know if this was helpful.

thanks

Hi to all,

I decided to go with a client script, but I still not get the correct script to really control the display with the application chosen value with u_purchase_licence == true. 

Here is my code:

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
    
	g_form.setDisplay('alert_application', false);
   }

   //Type appropriate comment here, and begin script below
	

    g_form.getReference('u_purchase_licence', doAlert); // doAlert is our callback function  not cmdb_ci_app
}
 
function doAlert(caller) { // reference is passed into callback as first arguments

	var list_appl = g_form.getValue('appl_request_access_choice');
	
   if ((caller.getValue() == 'true') || (list_appl != '')) {
    g_form.setDisplay('alert_application', true);
   }
   else {
	g_form.setDisplay('alert_application', false);
   }
}

If you can help me with this 

Thanks
