JSON RPC item tree for Zope3

Project Description

This package provides an JSON-RPC item tree implementation for Zope3.

Detailed Documentation


This package offers a JSONRPC tree view which can be used as navigation tree. Let’s show how we can register our jsonrpc tree view:

>>> from zope.configuration import xmlconfig
>>> import z3c.jsonrpc
>>> context = xmlconfig.file('meta.zcml', z3c.jsonrpc)
>>> context = xmlconfig.string("""
... <configure
...     xmlns:z3c="">
...   <z3c:jsonrpc
...       for="*"
...       class="z3c.jsontree.jsonrpc.JSONTreeItems"
...       permission="zope.Public"
...       methods="loadJSONTreeItems"
...       layer="z3c.jsonrpc.testing.IJSONRPCTestSkin"
...       />
... </configure>
... """, context)

Now we will setup some content structure based on the default zope folder class:

>>> from import Folder
>>> site  = getRootFolder()
>>> content = Folder()
>>> site['content'] = content

And we need to be able to get an absoluteURL for the form:

>>> import zope.interface
>>> import zope.component
>>> from zope.location.interfaces import ILocation
>>> from zope.traversing.browser.interfaces import IAbsoluteURL
>>> class FakeURL(object):
...     zope.interface.implements(IAbsoluteURL)
...     zope.component.adapts(ILocation, zope.interface.Interface)
...     def __init__(self, context, request):
...         pass
...     def __str__(self):
...         return u'http://fake/url'
...     def __call__(self):
...         return str(self)
>>> zope.component.provideAdapter(FakeURL)

JSON-RPC proxy

If we call our JSON-RPC tree item method, we can see the different JSON data on the different contexts:

>>> from z3c.jsonrpc.testing import JSONRPCTestProxy
>>> siteURL = 'http://localhost/++skin++JSONRPCTestSkin'
>>> proxy = JSONRPCTestProxy(siteURL)
>>> proxy.loadJSONTreeItems('z3cJSONTree')
{u'treeChilds': {u'childs':
[{u'hasChilds': False,
  u'contextURL': u'http://fake/url',
  u'url': u'http://fake/url/@@SelectedManagementView.html',
  u'linkHandler': u'',
  u'content': u'content',
  u'iconURL': u'',
  u'id': u'z3cJSONTree.::content'}],
  u'id': u'z3cJSONTree'}}

The content object has no items and returns some empty JSON data:

>>> proxy = JSONRPCTestProxy(siteURL + '/content')
>>> proxy.loadJSONTreeItems('z3cJSONTree')
{u'treeChilds': {u'childs': [], u'id': u'z3cJSONTree'}}


0.6.0 (2010-09-23)

  • reflect changes in zope packages, use new package externals
  • fix broken tests
  • Fix className handling in javacsript, it seems that newer version of JQuery can’t handle $.className.has(ele, …) use $(ele).hasClass(…) instead.
  • Fix: getParentsFromContextToObject, don’t return a parent chain if an item is a location proxied NotFound error object. It’s possible that such a NotFound object will wrap a context which we don’t allow in our parent chain at all.

0.5.1 (2009-03-10)

  • Fix: use imports from newest packages e.g.
  • Fix: be smart to NotFound error objects. NotFound errors are not locatable.

0.5.0 (2008-04-16)

  • Fix: adjust ITreeItems adapter. Added additional discriminator which prevents to get missused as /@@/ adapter if configured with base registry
  • implemented ITreeItems adapter which is responsible for list all items listed in tree
  • Initial Release
