Hi all,
I want to use acts_as_ferret’s multi_search to search two model classes
(Reviewable and Blog) at a time like
@results = Reviewable.multi_search(“jemen”, [Blog])
and I’m always getting the error
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.map
#{RAILS_ROOT}/vendor/plugins/acts_as_ferret/lib/class_methods.rb:131:in
id_multi_search' #{RAILS_ROOT}/vendor/plugins/acts_as_ferret/lib/class_methods.rb:113:inmulti_search’
#{RAILS_ROOT}/app/controllers/search_controller.rb:53:in `search’
I have configured indexing like this:
acts_as_ferret :fields => [:index_text, :index_locations], :single_index
=> true
acts_as_ferret :fields => [:index_text, :index_locations], :single_index
=> true
Maybe I’m doing something wrong?
Thanks,
Starburger
Sorry, the above error is for the bleeding edge version (wrong cut &
paste). Nevertheless for the stable version I get (in the same
scenario):
can’t convert String into Array

just don’t use multi_search with :single_index => true. In the
single_index case, you tell find_by_contents what additional models to
search with the :models option:
@results = Reviewable.find_by_contents(“jemen”, :models => [Blog])
or
@results = Reviewable.find_by_contents(“jemen”, :models => :all)
this indeed looks a bit like an inconsistent API, however it’s this way
because in the single_index case you have only one Ferret index (hence
find_by_contents is used), while multi_search runs a combined search
across multiple Ferret indexes.
Maybe in a future version I’ll integrate the multi_search functionality
into find_by_contents, too.
