將Python腳本導入到plone模板以呈現對象列表

Question

我試圖將對象列表呈現爲plone模板， 我用查詢來編寫python腳本以獲取對象列表，然後返回列表與對象。

lista-fixos = context.portal_catalog.searchResults(
     Subject = { "query": ["Destaques", "Destaques-fixo"], 
        "operator": "and" 
        } 
) 
lista-normal = context.portal_catalog.searchResults(
     Subject = { "query": ["Destaques"]} 

) 

lista-fixos.append(lista-normal) 

for e in lista-fixos: 
     if e not in lista-final: 
      lista-final.append(e) 
return lista-fixos 

在這裏，我試圖讓那麼

tal:define="results here/getCatalogDestaques.py" 

這裏是腳本和模板 http://pastie.org/5530478

我的問題是，每次我試圖調用模板它給我以下錯誤：

Answer 1

嘗試刪除.py部分來自呼叫。即：

tal:define="results here/getCatalogDestaques"
