Date iCal

This module contains code to create an iCal feed in Views. It has been pulled out of the Calendar iCal module because it has no dependency on Calendar and it could be used on any view. The code has also been generalized so that it will work for any entity, not just nodes. It creates an 'iCal' view mode for every entity type that can be used to to configure the description used in the iCal feed, and adds theme suggestions to tell Drupal to look for an iCal version of the entity template.

The Calendar iCal module will be deprecated in favor of this module.

This module is dependent on the Date API and Views modules.

Future plans for this module:

• Add in an iCal parser for the Feeds module that can parse an iCal feed from another site so it is possible to import as well as export iCal information.
• Add in ways to take advantage of other parts of the iCal specification, like LOCATION or VALARM.
• Add some pre-configured features that illustrate how to set up a site that provides an iCal feed and consume iCal information from other sites.

To use this module to create an iCal link on the bottom of a view page:

• Enable Date API, Views, and Date iCal.
• Go to the Display Fields screen for the entity you want to export in an iCal field. You will see that there is a new view mode for all entities, called 'iCal'.
• Set up the iCal view mode to contain whatever should be exported as the 'Description' field for the iCal field. You can trim the text to the desired size, include other fields, etc.
• Optional, but recommended, create a new node.tpl file for the iCal view mode, using the name ENTITYTYPE--ical.tpl.php or ENTITYTYPE--BUNDLE--ical.tpl.php. Make this a very simple template that omits the title, submitted by information, links, and comments. Place that file in the theme folder.
• Clear the cache so the new template can be discovered by Drupal.
• Create a new view that contains the items you want to display in the iCal feed.
• Add a feed to the view, using the feed type 'Date iCal'.
• Choose to 'Show' the feed as 'Date iCal Entities' (rather than 'Content' or 'Fields').
• In the settings for Date iCal Entities, select the specific date field that should be used as the event date for the iCal feed.
• Add date filters or arguments that will constrain the view to the items you want to display in the feed.
• Give the feed a path like 'calendar/ical/%/calendar.ics', where you have a '/%/' for every contextual filter in the view.
• Attach the feed to a page view.
• Navigate to the page view. You should see the iCal icon at the bottom of the view. If you click on the icon it will download an .ics file with the events that matched the view criteria.
