[Zope-CMF] printing out member roster grouped by custom property ZPT

[David (Hamish) Harvey]

Kristina,

Posting in html is unpopular.

The way I've done this is a bit ugly, but it works for me at the moment. I 
have an external method (not sure if it needs to be, maybe a python script 
would do) which looks like this:

def filteredMemberList(member_tool, attribute_name, salt):

    members = member_tool.getRoster()
    filtered = []
    for member in members:
        member_obj = member_tool.getMemberById(member['id'])
        attribute_value = member_obj.getProperty(attribute_name)
        if attribute_value==salt:
            filtered.append({'id':member['id'], 'listed':member['listed']})
    return filtered

I clearly copied some of it from somewhere (I wouldn't have used the 
parameter name "salt") but I'm not sure where. This will return a subset of 
members for whom the property "attribute_name" is set to == salt. My custom 
property that I'm grouping by is called member_group, and is constrained to 
a list of values called member_classes, so I can then repeat over the items 
in member_classes in a page template, and call filteredMemberList with each.

Here's a snippet of the page template that uses it

    <div metal:fill-slot="main"
          tal:define="mtool here/portal_membership;
                      ptool here/portal_memberdata;
                      member_classes 
python:ptool.getProperty('member_classes');
                      DateTime python:modules['DateTime'].DateTime;
                      Batch python:modules['ZTUtils'].Batch;
                      DateTime python:modules['DateTime'].DateTime;
                      b_start python:request.get('b_start', 0);">

      <metal:block tal:repeat="member_class member_classes">
      <div tal:define="members python:here.filteredMemberList(mtool, 
'member_group', member_class);">

<!-- do whatever you want with each member in the group here -->

      </div>
      </metal:block>

    </div>

Cheers,
Hamish
