It seems that delta indexing does not work on associated tables. Here
is what I have:
Lesson model:
define_index do
indexes title
indexes description
indexes steps.title, :as => :step_titles
indexes steps.instructions, :as => :step_instructions
has account_id
set_property :delta => true
end
Step is a different model. I have added delta fields to both the
Lesson and Step tables.
If I modify a lesson attribute Shpinx picks it up. But if I modify a
step attribute Sphinx doesn't pick it up. Exampes:
If I modify a lesson title to "Thiss Lesson"
Lesson.search "Thiss" returns the result.
But if I modify the first step of that lesson so that the step title
is "Annother step"
Lesson.search "Annother" doesn't return anything.
I have also tried adding this to my step model:
define_index do
indexes title
indexes instructions_search
has lesson_id
set_property :delta => true
end
Modifying the step attribute rotates the step index but doesn't update
the lesson index. So now Lesson.search("Annother") doesn't return
anything but Step.search("Annother") returns the step.
How can I trigger the lesson index when a step is modified?
Thanks,
