So following along with @Kevin Jump & some core codebase diving. With an entity action its registered with a property called

api

in the

manifest

We have a method in the example code called

Execute()

I am unsure how the Entity Action in the dropdown knows how to run the

Execute

method when the item is clicked? So a wider a question how would I know to have called the method this (as I get no completions to know about this method) ? Can @Jacob Overgaard or @Niels Lyngsø perhaps shed some light on this for me please

ts
import { UmbControllerHostElement } from "@umbraco-cms/backoffice/controller-api";
import { UMB_DOCUMENT_ENTITY_TYPE, UmbDocumentItemRepository } from "@umbraco-cms/backoffice/document";
import { UmbEntityActionBase } from "@umbraco-cms/backoffice/entity-action";
import { UMB_NOTIFICATION_CONTEXT, UmbNotificationContext } from "@umbraco-cms/backoffice/notification";

export class MyEntityAction extends UmbEntityActionBase<UmbDocumentItemRepository> {
    #notificationContext? : UmbNotificationContext;

    constructor(host: UmbControllerHostElement, repositoryAlias: string, unique: string) {
        super(host, repositoryAlias, unique, UMB_DOCUMENT_ENTITY_TYPE)

        console.log('repository alias', repositoryAlias);
        console.log('unique', unique);
        console.log('entity type', this.entityType);
        
        this.consumeContext(UMB_NOTIFICATION_CONTEXT, (instance) => {
            this.#notificationContext = instance;
        });
    }
    
    // Question: How do we know what is calling the execute method
    async execute() {
        this.#notificationContext?.peek('warning', {
            data: {
                headline: 'A thing has happened !',
                message: 'What that thing is? only time will tell.'
            }
        });
    }
    
}

if we did it proper, we should have an interface that lets you know to implement that and implement a crude version in the base class that throws an error basically

I put it up as a task here: https://github.com/umbraco/Umbraco.CMS.Backoffice/issues/1288

Remembered and re-found the other storybook site 🙂 This also mentions that there is

getHref

method as well or is the Storybook item describing actions out of date @Jacob Overgaard ? https://apidocs.umbraco.com/v14/ui/?path=/docs/guides-extending-the-backoffice-entity-actions--docs#the-entity-action-class
