Python Whoosh AttributeError when updating index

I'm trying to update my whoosh search index when I make changes to my database, but keep getting an error that I haven't been able to figure out.

One of my views:

from search import update_index

@view_config(route_name='update_effect_brief', permission='edit')
def update_effect_brief(request):
    name = request.matchdict['pagename']
    brief = request.params['effect_brief']
    effect = Effect.get_by_name(name) # This is an "effect" object
    effect.update_brief(brief)
    update_index(effect)
return HTTPFound(location=request.route_url('view_effect', pagename=name))

My search.py file:

from whoosh.index import create_in, open_dir

def update_index(obj):
    '''Update single ingredient, product or effect.'''
    index = open_dir('searchindex') # searchindex is the name of the directory

    with index.searcher as searcher: # crashes on this line!
        writer = index.writer()
        update_doc(writer, obj)

Traceback:

What am I doing wrong?

You need to call the index.searcher() method to create the context manager:

with index.searcher() as searcher:

See the Searcher object section in the Whoosh quickstart, and The Searcher object documentation.

It isn't entirely clear to me why you are creating a searcher, but then create a writer in the block and update the index. Perhaps you wanted to use the writer as a context manager instead here:

with index.writer() as writer:
    update_doc(writer, obj)

and leave the searcher for searching operations.
