Is there an easy way to count the number of occurences of a certain meta type in a Catalog? E.g: I want a dtml snippet that outputs:
Couldn't you do:
<dtml-call "REQUEST.set('counter', 0)">
<dtml-in "objectValues('DTML Document')"> <dtml-call "REQUEST.set('counter', counter+1)"> </dtml-in>
This folder (<dtml-var title_or_id) has <dtml-var counter> number of objects with the meta type DTML Document.
um, not to be nitpicking, but if you'd want to know the number of objects with a certain meta-type in a folder, the following is a bit shorter and saves you an iteration: <untested> <dtml-call "REQUEST.set('counter', _.len(objectValues(['DTML Document'])"> This folder (<dtml-var title_or_id) has <dtml-var counter> number of objects with the meta type DTML Document. <dtml-let counter="_.len(objectValues(['DTML Document'])"> This folder (<dtml-var title_or_id) has <dtml-var counter> number of objects with the meta type DTML Document. </dtml-let> </untested> not entirely sure of the dtml-let syntax, but you get the idea Rik
