Status messages are session-bound information which allow the user to see notifications when the page is rendered next time.

Status messages are stored session in safely manner which prevents Cross-Site Scripting attacks which might occur due to delivering message information as HTTP GET query parameters.

Status messages have text (unicode) and type (str). All pending status messages are shown to the user when the next page is rendered.

Example:

from Products.statusmessages.interfaces import IStatusMessage

messages = IStatusMessage(self.request)

messages.addStatusMessage(u"Item deleted", type="info")

Example which you can use in Python scripts:

# This message is in Plone i18n domain
context.plone_utils.addPortalMessage(_(u'You are now logged in. Welcome to supa-dupa-system.'), 'info')
