Question

I want to create an event content type with one field Dates contains a list of dates (not recurring dates) and displayed in Plone like the official event content type.

I want to have one event that display many times in the portlet Calendar.

Is this possible and how (which addon to use, …)

I’m currently trying MultiEvent addon (I have updated from Plone2.5 -> Plone4.1) but this addon need a cron to call an update method that change THE date to the next one. So you can’t see the event more than one time in the calendar.

It seems DateIndex can manage one date for one content. I’m looking for a Keyword Index but for dates.

Answer 1

You could make your Event content a folderish, and insert date intervals inside it (as another content type).

Retrieving them with catalog would look like:

catalog = getToolByName(context, 'portal_catalog')

catalog( object_provides=IMyDateInterval.__identifier__,
         sort_on='interval',
         interval={ 'query' : date_range, 'range' :'min:max'}
)

Hope it helps.
