python - 在 Plone 中添加用户之间关系的首选方法是什么？

Question

我正在制作一个由 Plone 提供支持的社交网站，并希望在用户( friend 、关注者等)之间建立关系。

我如何在 Plone 4 中实现这一点？

Answer 1

我建议使用 annotations并创建多棵树。例如:

import BTrees
from zope import annotation

FOLLOWERS_KEY = "my.product.followers"
FOLLOWS_KEY = "my.product.follows"
FRIENDS_KEY = "my.product.friends"

portal = self.context.portal_url.getPortalObject()
annotations = annotation.interfaces.IAnnotations(portal)

if not annotations.get(FOLLOWERS_KEY, None):
    annotations[FOLLOWERS_KEY] = BTrees.IIBTree.IITreeSet()
if not annotations.get(FOLLOWS_KEY, None):
    annotations[FOLLOWS_KEY] = BTrees.IIBTree.IITreeSet()
if not annotations.get(FRIENDS_KEY, None):
    annotations[FRIENDS_KEY] = BTrees.IIBTree.IITreeSet()

followers = annotation.get(FOLLOWERS_KEY)
follows = annotation.get(FOLLOWS_KEY)
friends = annotation.get(FRIENDS_KEY)
