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'
|
|
|
|
Working with resources
|
|
----------------------
|
|
|
|
>>> import os
|
|
>>> from loops.external.tests import dataDirectory
|
|
>>> loader.resourceDirectory = os.path.join(dataDirectory, 'import')
|
|
|
|
>>> input = ("resource('doc04.txt', u'Document 4', 'textdocument')\n"
|
|
... "resourceRelation('myquery', 'doc04.txt', 'standard')")
|
|
>>> reader = PyReader()
|
|
>>> elements = reader.read(input)
|
|
>>> loader.load(elements)
|
|
|
|
>>> sorted(resources)
|
|
[u'd001.txt', u'd002.txt', u'd003.txt', u'doc04.txt']
|
|
|
|
Working with nodes
|
|
------------------
|
|
|
|
>>> input = ("node('home', u'Home', '', u'menu', body=u'Welcome')\n"
|
|
... "node('myquery', u'My Query', 'home', u'page', "
|
|
... " target='concepts/myquery')")
|
|
>>> reader = PyReader()
|
|
>>> elements = reader.read(input)
|
|
>>> loader.load(elements)
|
|
|
|
|
|
Exporting loops Objects
|
|
=======================
|
|
|
|
Extracting elements
|
|
-------------------
|
|
|
|
>>> from loops.external.base import Extractor
|
|
>>> extractor = Extractor(loopsRoot, os.path.join(dataDirectory, 'export'))
|
|
>>> elements = list(extractor.extract())
|
|
>>> len(elements)
|
|
20
|
|
|
|
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'', typeInterface=u'', viewName=u'')...
|
|
type(u'query', u'Query', options=u'', typeInterface='loops.query.IQueryConcept',
|
|
viewName=u'')...
|
|
concept(u'myquery', u'My Query', u'query', options=u'', viewName='mystuff.html')...
|
|
child(u'projects', u'customer', u'standard')...
|
|
resource(u'doc04.txt', u'Document 4', u'textdocument', contentType='text/restructured')
|
|
resourceRelation(u'myquery', u'doc04.txt', u'standard')
|
|
node('home', u'Home', '', u'menu', body=u'Welcome')
|
|
node('myquery', u'My Query', 'home', u'page', target=u'concepts/myquery')...
|
|
|
|
|
|
The Export/Import View
|
|
======================
|
|
|
|
>>> from loops.external.browser import ExportImport
|
|
>>> from zope.publisher.browser import TestRequest
|
|
|
|
>>> input = {'field.data': output, 'resourceDirectory': dataDirectory}
|
|
>>> view = ExportImport(loopsRoot, TestRequest(input))
|
|
>>> view.upload()
|
|
False
|
|
|
|
|
|
Fin de Partie
|
|
=============
|
|
|
|
>>> placefulTearDown()
|
|
|
|
>>> exportDir = os.path.join(dataDirectory, 'export')
|
|
>>> for fname in os.listdir(exportDir):
|
|
... os.unlink(os.path.join(exportDir, fname))
|
