how do I invoke a view from within couchdb?

[Matteo Caprari]

Hi.

In an authorization handler I need to query a view (map only) with a single key.
The map function emits (openid, username) and there is no reduce.

I thounk I have to complete the snippet below with couch_view:fold but
can't figure out how to generate
a valid fold function, let alone one that filters on a given key.

find_user_with_openid(Db, OpenId) ->
        DesignId = <<"_design/_openid">>,
        ViewName = <<"users_by_openids">>
        Stale = nil,
        {ok, View, Group}  = couch_view:get_map_view(Db, DesignId, ViewName, 
nil),

Thanks.
