Re: Zope View Tutorial

Hey Joe,

You don't ask a specific question. Did you try something and get an error?

I suggest starting your view without restricting the views/interfaces, and worrying about that when you have all the other logic working.

Here's what it takes to get the example you referenced at http://developer.plone.org/members/member_basics.html#list-users-within-all-groups running.

First you tell Plone about your entry point. In the browser directory, in configure.zcml, add

    <browser:page
        for="*"
        name="test_user_view"
        class=".common.TestUserView"
        permission="zope2.View"
        />

This says when someone goes to the url test_user_view, run the code in the class common.TestUserView.

To create the class, create a file called common.py in the browser directory, and in common.py, add

from Products.Five import BrowserView
from Products.CMFCore.utils import getToolByName
import logging
logger=logging.getLogger("MyLogger: ")

class TestUserView:

    def __call__(self):
        """Testing views"""
        logger.info("TestUserView: __call__: ")
        acl_users = getToolByName(self.context, 'acl_users')
        groups_tool = getToolByName(self.context, 'portal_groups')
        groups = acl_users.source_groups.getGroupIds()
        for group_id in groups:
            group = groups_tool.getGroupById(group_id)
            if group is None:
                continue
            logger.info("TestUserView: __call__: group: %s" % str(group))
            members = group.getGroupMembers()
            member_emails = [m.getProperty('email') for m in members]
            logger.info("TestUserView: __call__: member_emails: %s" % str(member_emails))


Notice that I added some logging to their example. 

You can access that code at http:blahblahblah/yourplonesite/test_user_view

Hope this helps,
Mike

I am trying to implement the examples at http://developer.plone.org/members/member_basics.html#list-users-within-all-groups because we are primarily interested in user information at this time.   Here are some of the things I have been tasked to do:

I understand the basic idea of a view,   but determining the interface, the class, and the python code to get the examples on http://developer.plone.org/members/member_basics.html#list-users-within-all-groups to work is something I just don't see yet.  I understand Zope browser views are an important part on Plone 4 and I need to understand how to use them, but I am frankly stuck.  I don't want to have to ask someone to build every one of these I need.  I need to get the principals down so I can build them on my own.  Any suggestions?

I don't have any experience with an object oriented programming language.  I have been programming web pages since 1998, mostly with ColdFusion and database applications since the 1990's with Visual Basic and SQL Server.  I am the web administrator for the College of Education at Penn State University.  You can see our site at http://www.ed.psu.edu.
