Feeds importing unique nodes over and over

Question

I'm trying to import events to a calendar from an external ics.. I installed the Calendar module with the Feeds module. Unfortunately it creates the whole time new nodes. Even if the UID is unique (mapped to field field_gimme_uid) in the node. Update nodes is setted 'on'. I have checked everything but everything seems alright. The unique field is correctly imported (and the same for multiple nodes)..

I have a contenttype "Evenement" with the following fields:

• Evenement (title)
• Datum (field_event_date) Date
• Gimme-UID (field_gimme_uid) Text

I have a feed that maps the ics import to the nodes

$feeds_importer = new stdClass();
$feeds_importer->disabled = FALSE; /* Edit this to true to make a default feeds_importer disabled initially */
$feeds_importer->api_version = 1;

My modules:

• Drupal 7.56
• Calendar module 7.x-3.5
• Date 7.x-2.10
• Date iCal 7.x-3.9
• Feeds 7.x-2.0-beta4

My ICS that I use to import can you find here

Why is it importing the whole time the same nodes?

Answer 1

My bad! The "Unique" option in the feeds module isn't working without the module "Field Validation". I added an unique rule to the contenttype "evenement" and now it works like a charm!

Answer 2

The "Unique" option in the feeds module is working out-of-the-box only with title field. If you're using another field - you need "field validation" module
