Hi Pat,
I have a couple of STI models that aren't working with facet searches.
They look like:
class Medium < ActiveRecord::Base
define_index do
...
indexes :type, :facet => true
...
end
end
class Video < Medium; end
class Document < Medium; end
class Story < Document; end
class Joke < Document; end
etc.
When I try to do a Medium.facet 'foo' I get an exception thrown on
line 113 of facet_search.rb (on version 1.3.18) because the facet
returned by #facet_from_object is nill. Seems that all the classes
that inherit from Medium have an empty array returned by
#sphinx_facets. The Medium object has the :type_facet in the array
from #sphinx_facets.
I've monkey patched TS with the following, and it seems to work (our
models only have 1 index each), but I haven't looked much at TS's
innards, so if you have a better solution, please let me know:
class ThinkingSphinx::FacetSearch
def facet_from_object(object, name)
if object.sphinx_indexes.first.model != object.class
faceted_object = object.sphinx_indexes.first.model
end
faceted_object.sphinx_facets.detect { |facet| facet.attribute_name
== name }
end
end
