after getting some help from Martin I was able to solve some of the
problems I found in my implementation. now I have methods for getting
default values and vocabularies and they work like a charm.
but when I tried to change the order of the fields I found
IOrderableSchemaExtender only knows about fields defined inside my
extender. it wouldn't work for me because I want to move 'relatedItems'
and 'subject' around schematas.
Erik Rose showed me the ISchemaModifier adapter that, if I understood
correctly, let me do everything by modifying the schema directly.
my question now is, what's the best and/or safer approach to accomplish
what I want:
class NITFExtender(object):
adapts(IATNewsItem)
implements(ISchemaExtender)
implements(ISchemaModifier)
or
class NITFExtender(object):
adapts(IATNewsItem)
implements(ISchemaModifier)
in the first case, I can use ISchemaExtender to add the new fields and
ISchemaModifier to change schemata and order.
in the second case, I can use ISchemaModifier to add the new fields and
change schemata and order.
saludos
