I don't know why this post was not sent here yesterday...
Hi Hector,
finally my extender is working the way I wanted; thanks for your help, man!
Yay! :)
now I'm writing some tests to verify that everything is fine; I found one issue
and something not working (at least, not for me) in your doctest:
Does my doctest run if you run all the schemaextender tests? They all pass
here, so I suspect there's something wrong with your test setup.
first, *usage.txt* starting on line 142:
>>> schema = taggable_doc.Schema()
>>> 'schemaextender_test_tags' in schema
False
>>> 'schemaextender_test_highlighted' in schema
False
If it doesn't work, then your adapter isn't registered in your test.
this doesn't work at all; I changed to something like this:
class TestNewsItem(JuliusLiteTestCase):
""" ensure content type implementation """
def afterSetUp(self):
self.folder.invokeFactory('News Item', 'news1')
self.news1 = getattr(self.folder, 'news1')
def testExtendedFields(self):
extended_fields = ['property', 'section', 'urgency', 'byline']
schema = getNames(self.news1.Schema())
for field in extended_fields:
self.failUnless(field in schema)
so you're missing the getNames() method.
Huh? getNames() is a global method in that code. I don't know where you
imported it from or why you're using it. Is this working for you?
/me thinks ...
this may be a Plone 2.5/AT 1.4 discrepancy; I haven't tried it on that platform
as you nkow.
second, *usage.txt* starting on line 33:
>>> self.folder.invokeFactory('Document', 'taggable-document')
'taggable-document'
>>> taggable_doc = getattr(self.folder, 'taggable-document')
>>> ITaggable.providedBy(taggable_doc)
True
this doesn't work for me:
class TestExtender(JuliusLiteTestCase):
""" ensure extender implementation """
def afterSetUp(self):
zope.component.provideAdapter(NITFExtender, provides=ISchemaExtender,
name=u'Products.nitf4plone.extender')
self.folder.invokeFactory('News Item', 'news1')
self.news1 = getattr(self.folder, 'news1')
def testProvidesSchemaExtender(self):
self.failUnless(ISchemaExtender.providedBy(self.news1))
def testProvidesSchemaModifier(self):
self.failUnless(ISchemaModifier.providedBy(self.news1))
both methods fail.
Well, it'd only work if you had a field that actually did what the
TaggableField or whatever it's called does in the usage.txt text. It's an
example of something you may do with at.se, not something you'll see every time.
I tried also:
#this one fails
self.failUnless(verifyObject(ISchemaExtender, self.news1))
#this one pass
self.failUnless(verifyClass(ISchemaExtender, ATNewsItem))
Why did you try this? It's non-sensical. ISchemaExtender is an *adapter*.
verifyObject/Class tests whether a particular interface is *provided by* an
instance/class. It'll never pass.
