[Zope] NEWBIE: assign next free ID automatically

[jensebaer]

Hi,

it is not tested but may it works

<dtml-call "REQUEST.set('newid', _.string.atoi('0'))"
<dtml-in "objectValues('DTML Document')">
  <dtml-if "_.int(id) >= newid">
    <dtml-call "REQUEST.set('newid', _.int(id) + _.string.atoi('1'))">
  </dtml-if>
</dtml-in>

Your new id is: <dtml-var newid>



may you have to use _.string.atoi(id) instead _.int(id)

Viel Glück

Jens
