I have an issue with facet visibility in subclasses that are part of a
single table inheritance (STI) relationship that I would very much
appreciate some help with:
Given the below classes:
class Vehicle
define_index do
indexes make,
indexes model
end
end
class Car < Vehicle
define_index do
has number_doors, :facet => true
end
end
class Motorbike < Vehicle
define_index do
has final_drive, :facet => true
end
end
When I perform a search
@cars = Car.search 'Ford'
@facets = @cars.facets :with => { :number_doors => '2' }
The query runs and the results are displayed BUT a warning is logged:
Sphinx Daemon returned warning: index vehicle_core: no such filter
attribute 'number_doors'
If I move the number_doors attribute to the Vehicle model it is no
longer found.
If I declare it in both models the error disappears but the facet
total is doubled.
Is this expected behaviour or am I doing something wrong?
As background info I'm using:
Rails: 2.3.8
TS: 1.4.5
Sphinx 0.9.9
Any help greatly appreciated!
