How can i detect if an attachment has been deleted ?

[Anya CHOUKRANE]

Hello everyone, 

I am working on listeners in order to control who can add and delete attachments. I was able to do it for the adding part by using this code on my listener.

List changeItems = event.getChangeLog()?.getRelated("ChildChangeItem")
                    changeItems.each {GenericValue gv ->
                        if (gv["field"] == "Attachment" && gv["newvalue"]) {
                            attachmentIds.add(gv["newvalue"])
                        }
                    }

 But for the deleted attachment part i have no idea. How can i detect if an attachment has been deleted ? 

Thank you in advance.

Hello @Anya CHOUKRANE 

Welcome to the community.

The ability to create and delete attachments can be managed through the Permission Scheme associated with a project, for Classic projects at least. Is there a reason that methodology doesn't work for your scenario?

Hello, thank you for your response.

My goal is to restrict the permission of adding/deleting attachments based on a custom field value. This is not possible to do from the administration menu. I was able to do it for the adding part (i created a listener on "Issue update"  that automatically deletes an added attachment if the condition with the custom field is not met).

I want now to restrict who can delete attachment based on the same custom field value.

Thank you
