Lauren Matheson	Friday 09 January 2004 4:13:34 pm What is the best way to test for existence of an attribute? I have been using: {section show=$MinGroup:item.data_map.link\|not} This works, but naturally ez complains: No such attribute for array(4): link Choose one of following: name, intro, body, image
Lauren Matheson	Wednesday 14 January 2004 5:38:05 pm my solution is: ... Wrong {section show=$MinGroup:item.data_map\|contains('link')} will not work because we need to test against the keys of data_map, not the values. Back to the drawing board.
Lauren Matheson	Thursday 15 January 2004 6:38:29 am Here is a solution that actually works. Apply the patch to add a keys operator, then use: {section show=$MinGroup:item.data_map\|keys\|contains(link)} The patch is filed in bug report: http://ez.no/developer/ez_publish_3/bug_reports/keys_array_operator_patch_attached Because alignment is not preserved when text is posted to the bug system, you will have to cut and paste the patch into your ezpublish implementation.

{section show=$MinGroup:item.data_map|contains('link')}
will not work because we need to test against the keys of data_map, not the values. Back to the drawing board.

{section show=$MinGroup:item.data_map|keys|contains(link)}
