zeam.utils.batch 0.2

zeam.utils.batch

This package provides a batch functionality for Zope 2 and Zope 3.

You can use it like that:

1. Your container which is going to handle the batch must implements the marker interface zeam.utils.batch.interfaces.IBatchedContent.

2. You create your batch object on your view code:

   from zope.component import queryMultiAdapter
   from zeam.utils.batch import batch
   from zeam.utils.batch.interfaces import IBatchView
   
   
   class MyViewClass(...):
   
      def update(self):
         fulllist = ...
         self.myitems = batch(fulllist, count=10, name='myitems', request=self.request)
         self.batch = queryMultiAdapter((self.context, self.myitems, self.request),
                                        IBatchView)()

3. You use it in your template:

   <tal:navigation tal:replace="structure view/batch" />
   
   <tal:items tal:repeat="item view/myitems">
        ...
   </tal:items>
   
   <tal:navigation tal:replace="structure view/batch" />

That’s it.
