我有一個以zope 3 zcml工作的python類方式，但是我想將python移動到可以通過沿着tal的內容：content ='context/get_tags'。這是代碼，因爲它主張：將基於zcml的python腳本轉換爲zope/plone中的獨立腳本
class TagListView(BrowserView):
def getCategories(self):
categories = set()
for cat in self.portal_catalog.uniqueValuesFor('Subject'):
categories.add(cat.lower())
for cat in self.__mapping:
categories.add(cat.lower())
return tuple(sorted(categories))
def getSynonyms(self,category):
r = self.__mapping.get(category)
if r is None:
return()
return r[0]
def __init__(self,context,request):
self.context = context
self.request = request
self.tool = self.context.portal_categories
def entries(self):
taglist = '(['
for category in self.tool.getCategories():
taglist = taglist + '\'' + category + '\','
for synonym in self.tool.getSynonyms(category):
if len(synonym) > 0:
taglist = taglist + '\'' + synonym + '\','
taglist = taglist + '])'
return taglist
不是很大（因爲你可能已經猜到了程序員不是我的職務），但它是我所。我如何將它轉換爲獨立腳本工作？
