Display error message when, removing attachment is not allowed.

[Aman Thakur]

Hello all,

I needed help in a requirement which involves showing an error message on INC table record when someone tries to remove an attachment on it and is not allowed to do so.

I tried a "Delete" BR on the "sys_attachment" table, but the error message does not appear on INC table (form view).

I guess it has something to do with "gs" object used in gs.errorMessage.

So wanted to know if it is possible to do this.

Thanks.

Hi @Aman Thakur ,

1. You can try alternative ways like create an ACL that stops from deletion of attachment.

2. Try to Hide the X or delete button on Incident table to disallow attachment deletion on incident table.

Hi @Aman Thakur ,

You can use "g_form.disableAttachments();" to hide the paper icon based on your access.

Thankyou @Runjay Patel & @Sohail Khilji , for your replies.

The Scenario: Users can remove only those attachments on INC record that were added by a particular group (let's say Group 1). So, only those attachments can be removed/deleted which were added by Group 1 members.

But based on your replies, can it be concluded that this cannot be achieved using BR and gs.errorMessage() method?

Because I could see the error messages on "sys_attachment" list view when I tried removing/deleting an attachment directly from Attachment table.

Thanks.

Hi @Aman Thakur ,

On that case you can use ajax call to check the user belong to group or not. if dont then use "g_form.disableAttachments();"

1. Create onload client script and use below code.

var ga = new GlideAjax('UserUtils');
    ga.addParam('sysparm_name', 'checkGroupUser');
    ga.addParam('sysparm_caller_sys_id', group_name);
    ga.getXML(hideAttachment);
    function hideAttachment(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        
        if (answer=='false') {
           g_form.disableAttachments();
        }

2. create script include and use below code.

var UserUtils = Class.create();
UserUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    checkGroupUser: function() {
        var group= this.getParameter('sysparm_group_sys_id');
        var gr = new GlideRecord('sys_user_grmember');
        gr.addQuery('group',group);
gr.addQuery('user',gs.getUserID());
if(gr.next())
        return true;
else
return false;
    },


    type: 'UserUtils'
});
