expr="id <> 'index_html" issue
Okay, this is my second question for the day. Hopefully it won't be as easy as the first -- otherwise, I'll have to stick to practicing law. I'm looking for a way to list the DTML Methods in a folder -- except the index_html method. So far, I've had to do it by using this: <dtml-in expr="objectValues('DTML Method')" sort="title"> <dtml-if expr="title <> 'The Title'"> <td align="center"><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></td> </dtml-if> </dtml-in> This works but it is a maintenance headache. A more elegant (and reuseable) solution would be to use the id, which is always 'index_html' for the to-be-excluded method. However... <dtml-in expr="objectValues('DTML Method')" sort="title"> <dtml-if expr="id <> 'index_html'"> <td align="center"><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></td> </dtml-if> </dtml-in> .. doesn't work. Does anyone know why? Thanks in advance, Ron ./.

Short answer because id is not always a string you have to call it differently try <untested but this is a faq>: <dtml-in expr="objectValues('DTML Method')" sort="title"> <dtml-if expr="_[id] <> 'index_html'"> <td align="center"><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></td> </dtml-if> </dtml-in> hth Rik
try <untested but this is a faq>:
<dtml-in expr="objectValues('DTML Method')" sort="title"> <dtml-if expr="_[id] <> 'index_html'"> <td align="center"><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></td> </dtml-if> </dtml-in>
that should be <dtml-if expr="_['id'] <> 'index_html'"> (quotes round id) <dtml-if expr="id() <> 'index_html'"> would also work. This is because sometimes id is a property, sometimes it's a method. The former version would work in every case; the latter only where id is a method. It's annoying, but there's talk of providing a getId() method for every object to sort this inconsistency out. seb

As far as I know, getId() is in CVS and is documented in the CVS API online help. You should be seeing it soon. -Michel
hi, as usual, if such things happen, "id" is a method. it gets called by zope if you just use <dtml-var > on it. So either use id() or better, look for title and if not set (dont set a title on html_index then) dont display it. Regards Tino complaw@hal-pc.org wrote:
