Import iCal to Plone 5

JotaMG · March 1, 2016, 12:18pm

Hi!
Is there any easy way to import a iCal file containing some events into Plone, so that they appear in the Plone calendar?

I really apreciate some help, ideas, tips on how to import a iCal file into Plone 5 events???

Likely undocumented, and I do not have experience with this, but reading the source yields reasonable clues that support is there:

github.com

plone/plone.app.event/blob/master/plone/app/event/ical/importer.py#L35


from zope.event import notify
from zope.interface import alsoProvides
from zope.interface import implementer
from zope.interface import Interface
from zope.interface import noLongerProvides
from zope.lifecycleevent import ObjectModifiedEvent


import datetime
import icalendar
import random
import six
import transaction




def ical_import(container, ics_resource, event_type,
                sync_strategy=base.SYNC_KEEP_NEWER):
    cal = icalendar.Calendar.from_ical(ics_resource)
    events = cal.walk('VEVENT')


    cat = getToolByName(container, 'portal_catalog')
    container_path = '/'.join(container.getPhysicalPath())

Unfortunately undocumented and unfortunately a bit broken. This is how it works:

Create a folder where you want the events to be imported
In the toolbar, click on actions > enable ical import
You will get an error message "This page does not seem to exist…"
Remove the "/enable" part of the URL, so that you're viewing "@@ical_import_settings"
Fill the form and click "Save and Import". Should be self-explanatory.

You can also use a remote url and use wget (with authentication) to regulary synchronize with a remote ical file. Poors-man calendar server
@jone created one an experimental CalDAV implementation for plone.app.event. I don't know about the status yet, but it would definitely be interesting to further develop this: https://github.com/4teamwork/ftw.caldav

Well, for me it worked ok, no problems, no errors, no "This page does not seem to exist…"
(Plone 5.0.2, plone.app.event 2.0.6)
Thank you very much!

The icalendar parser does not like your ical file, that much is obvious.
Either share your ical file here if it's not confidential, or test it offline yourself using python.
Taking a look at it could be enlightening by itself (maybe it has been turned into a html file ? icalendar expects a plain text file)

I am not able to attach the iCal file here, looks like it allows only image file extensions.

gp54321 · January 16, 2018, 5:40pm

an Ical file is a text file, there should not be any problem just pasting the content here. This is a sample found on Wikipedia:
