[Zope-dev] dtml-in: next-batches

[Bryan Baszczewski]

I found this in some Zope documentation.  It wont give you "1,2,3,4,5...10"
it gives "(1-10)(11-20)(21-30)...". Monkey with it a little and you'll get
it.  Beware it will call your External Method or ZSQL as many times/10.

<dtml-in expr="SOME_EXTERNAL_METHOD(REQUEST)" previous orphan=1 size=10
start=qs>
<dtml-in previous-batches mapping>
<dtml-unless sequence-start>, </dtml-unless>
<a href="<dtml-var document_id><dtml-var sequence-query
>qs=<dtml-var batch-start-number>">
(<dtml-var batch-start-number> - <dtml-var batch-end-number>)</a>
</dtml-in>
</dtml-in>

<dtml-in expr="SOME_EXTERNAL_METHOD(REQUEST)" next orphan=1 size=10
start=qs>
<dtml-in next-batches mapping>
<dtml-unless sequence-start>, </dtml-unless>
<a href="<dtml-var document_id><dtml-var sequence-query
>qs=<dtml-var batch-start-number>">
(<dtml-var batch-start-number> - <dtml-var batch-end-number>)</a>
</dtml-in>

</dtml-in>
<dtml-in expr="SOME_EXTERNAL_METHOD(REQUEST)" orphan=1 size=10 start=qs>
<dtml-var sequence-index>)">
<dtml-var expr="_.getitem('sequence-item')[1]">
<dtml-var expr="_.getitem('sequence-item')[2]">
</dtml-in>

Does anybody have an example of how to use the supposed next-batches
mapping returned by dtml-in?
I'm trying to build a google-like pageing feature into my application,
so we just show the first 5 results, then have a link to each next
page, ie "1,2,3,4..."
Thanks,
-Brett
