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:in
`multi_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

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. Jens -- Jens Kr?mer webit!
