I have a product template with a multiselect that searches for other product items. For this I use a sitecore query on the source field of the multiselect:
query:fast:/sitecore/content/Home//*[@@templateid='{DEFA2E43-E688-48E5-AE28-1ABA761105E2}']
With this query all the products are show in the select including the current product item.
How can I exclude the product item I'm working on? (exclude self?)
Thanks in advance
You should be able to use the ExcludeItemsForDisplay where you set the ID of the Item you want to exclude.
See link - http://firebreaksice.com/tame-your-sitecore-treelists/
The complexity will then be to set the ID programmatically via fast-query, i.e. self, unless hardcoding it can meet your requirement.
I think the right way to do this is using the getLookupSourceItems pipeline. I've written a blog post about this pipeline here:
http://ctor.io/dynamic-field-sources-with-getlookupsourceitems-pipeline/
Within this pipeline you know the id of the current item with args.Item.ID. You can then rewrite the source dynamically to a query excluding the current item. Something like this (untested):
query:fast:/sitecore/content/Home//*[@@templateid='{DEFA2E43-E688-48E5-AE28-1ABA761105E2}' and @@id != '<current item id>']
The source can be rewritten with args.Source (please see the blog post for more information).
