Added in Version 12.1

Action and Links (also called Connections) are two ways to provide the end user more interaction with the document. The image below shows what they are :

Actions

A DocType may have some DocType Action that will result in a button creation on the DocType View. Supported actions are:

1. Server Action: This will trigger a whitelisted server action.
2. Route: This will redirect to a given route.

Configuration of Action

Configuration of Action in custom app

To call an Action in you own app, you will need a python function decorated with frappe.whitelist :

import frappe

@frappe.whitelist()
def execute_function(*args,**kwargs):
    """
    This fonction will be executed when the Execute Action Button will be clicked
    """
    print('Hello World')
    # The data is transmitted via keyword argument
    print(kwargs)

This code should go somewhere inside you app, typically in a file like apps/my_app/my_app/api.py

And then, configure the correspondant Action path :

Connections (Linked Documents)

A standard navigation aid to the DocType view is the Connections section on the dashboard. This helps the viewer identify at a glance which document types are connected to this DocType and can quickly create new related documents.

These links also support adding internal links (links to DocType in child tables).
