Status messages

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.

Setting a status message

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')
