loops - Linked Objects for Organization and Processing Services
===============================================================
($Id$)
>>> from zope import component
>>> from zope.traversing.api import getName
Let's set up a loops site with basic and example concepts and resources.
>>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
>>> site = placefulSetUp(True)
>>> from loops.tests.setup import TestSite
>>> t = TestSite(site)
>>> concepts, resources, views = t.setup()
>>> loopsRoot = site['loops']
>>> len(concepts), len(resources), len(views)
(11, 3, 0)
Importing loops Objects
=======================
Reading object information from an external source
--------------------------------------------------
>>> from loops.external.pyfunc import PyReader
>>> input = "concept('myquery', u'My Query', 'query', viewName='mystuff.html')"
>>> reader = PyReader()
>>> elements = reader.read(input)
>>> elements
[{'type': 'query', 'name': 'myquery', 'viewName': 'mystuff.html', 'title': u'My Query'}]
Creating the corresponding objects
----------------------------------
>>> from loops.external.base import Loader
>>> loader = Loader(loopsRoot)
>>> loader.load(elements)
>>> len(concepts), len(resources), len(views)
(12, 3, 0)
>>> from loops.common import adapted
>>> adapted(concepts['myquery']).viewName
'mystuff.html'
Exporting loops Objects
=======================
Extracting elements
-------------------
>>> from loops.external.base import Extractor
>>> extractor = Extractor(loopsRoot)
>>> elements = list(extractor.extract())
>>> len(elements)
13
Writing object information to the external storage
--------------------------------------------------
>>> from loops.external.pyfunc import PyWriter
>>> from cStringIO import StringIO
>>> output = StringIO()
>>> writer = PyWriter()
>>> writer.write(elements, output)
>>> print output.getvalue()
type(u'customer', u'Customer', options=u'', viewName=u'')...
type(u'query', u'Query', options=u'', typeInterface='loops.query.IQueryConcept',
viewName=u'')...
concept(u'myquery', u'My Query', u'query', viewName='mystuff.html')...
child(u'projects', u'customer', u'standard')...
The Export/Import View
======================
>>> from loops.external.browser import ExportImport
>>> from zope.publisher.browser import TestRequest
>>> input = {'field.data': output}
>>> view = ExportImport(loopsRoot, TestRequest(input))
>>> view.upload()
False
