Dialog API

Frappe provides a group of standard, interactive and flexible dialogs that are easy to configure and use. There's also a more extensive API for Javascript .

frappe.msgprint

frappe.msgprint(msg, title, raise_exception, as_table, as_list, indicator, primary_action, is_minimizable, wide, realtime)

This method works only within a request / response cycle. It shows a message to the user logged in to Desk who initiated the request.

The argument list includes:

msg : The message to be displayed
title : Title of the modal
as_table : If msg is a list of lists, render as HTML table
as_list : If msg is a list, render as HTML unordered list
primary_action : Bind a primary server/client side action.
raise_exception : Exception
is_wide : Show a wide modal
is_minimizable : Allow users to minimize the modal
realtime : publish immediately using websocket instead of adding to response message log

frappe.msgprint(
    msg='This file does not exist',
    title='Error',
    raise_exception=FileNotFoundError
)

frappe.msgprint

primary_action can contain a server_action or client_side action which must contain dotted paths to the respective methods. The JavaScript function must be a globally available function. You can also pass hide_on_success to close the message after the action is successfully completed.

# msgprint with server and client side action
frappe.msgprint(msg='This file does not exist',
    title='Error',
    raise_exception=FileNotFoundError
    primary_action={
        'label': _('Perform Action'),
        'server_action': 'dotted.path.to.server.method',
        'client_action': 'dotted.path.to.client.method',
        'hide_on_success': True,
        'args': args
    }
)

frappe.msgprint with primary action

frappe.throw

frappe.throw(msg, exc, title, is_minimizable, wied, as_list, primary_action)

This method will raise an exception as well as show a message in Desk. It is essentially a wrapper around frappe.msgprint .

exc can be passed an optional exception. By default it will raise a ValidationError exception.

frappe.throw(
    title='Error',
    msg='This file does not exist',
    exc=FileNotFoundError
)
