我试图将一个对象列表渲染到一个 plone 模板中,我用查询编写了 python 脚本来获取一个对象列表,然后它返回一个包含对象的列表。

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

在这里我试着得到

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

这是脚本和模板 http://pastie.org/5530478

我的问题是每次我尝试调用模板时都会出现以下错误:

尝试.py从通话中删除该部分。IE:

tal:define="results here/getCatalogDestaques"
