Hi
I suggest to use the following function that
def get_grouped_list(self, seq=[], size=3): #get the list with all items grouped return [seq[i:i+size] for i in range(0, len(seq), size)]
that takes as parameter a list and goups items in slices with length = size.
def get_grouped_list(seq=[], size=3): ... return [seq[i:i+size] for i in range(0, len(seq), size)] ... l = [1,2,3,4,5,6,7,8] get_grouped_list(l) [[1, 2, 3], [4, 5, 6], [7, 8]] get_grouped_list(l, 4) [[1, 2, 3, 4], [5, 6, 7, 8]]
Then iterating this is something like:
<tr tal:repeat="slice python:<someobject>.get_grouped_list(yourlist)"> <td tal:repeat="item slice"> <span tal:replace="item" /> </td> </tr>

Hello all , I'm trying to display on the same page a table with (3 columns) with content from a list . I'm trying to batch the results so that every 3 elements anothe row is created. Can anyone give me a clue how to do that ?
this is my code:
<table tal:define="Rnumber python:context.cm1.content.specialfile.getList('link_list') ; batch python:modules['ZTUtils'].Batch(Rnumber,size=3,start=0)"> <th colspan="3">Main Title</th> <tr><th>Title 1</th><th>Title 2</th><th>Title 3</th></tr> <tr> <td tal:repeat="num batch"> <span tal:condition="python:num < 3" tal:replace="structure num"> content goes here.. </span> </td> </tr> <!-- <tr> <td tal:repeat="num batch"> <span tal:replace="structure num"> Material goes here </span> </td> </tr> --> </table> Thanks for your suggestion Dragos , I want to do it the zope batch way (I suppose it is simpler) if I can... I will keep in mind your function if nothing else can be done.
The ZTUtils batching is mostly for batching between pages. It's probably easier to do it in a Python script. --jcc -- "Building Websites with Plone" http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com
