[Grok-dev] Adding indexes with the same field names

[Dirceu Pereira Tiegs]

Hello guys,

I have two classes implementing these two interfaces:

class IBook(interface.Interface):
     title = schema.TextLine(title=u"Title", required=True)
     # more attributes here

class IArticle(interface.Interface):
     title = schema.TextLine(title=u"Title", required=True)
     # more attributes here

And these two indexes:

class BookIndexes(grok.Indexes):
     grok.site(BookShelf)
     grok.context(Book)
     book_title = index.Text('title') # should use title of IBook

class ArticleIndexes(grok.Indexes):
     grok.site(BookShelf)
     grok.context(Article)
     article_title = index.Text('title') # should use title of IArticle

Well, when I test the application I get the following error:

Exception raised:
     Traceback (most recent call last):

line 50, in setup
         field_callable=call,
     TypeError: __init__() got multiple values for keyword argument  
'field_name'

My question is: how can I add these two indexes with the same  
attribute name?

Thanks in advance,
