Using sunspot to search down model hierarchy

问题:

Example:

I have the following:

class Person < ActiveRecord::Base
  has_many :educations
end

class Education < ActiveRecord::Base
  belongs_to :school
  belongs_to :degree
  belongs_to :major
end

class School < ActiveRecord::Base
  has_many :educations
  # has a :name
end

I want to be able to return all people who went to a specific school so in my PeopleController#index I have

@search = Person.search do
  keywords params[:query]
end

@people = @search.results

How do I create the searchable method on the Person model to reach down into school? Do I do something like this:

searchable do
  text :school_names do
    educations.map { |e| e.school.name }
  end
end

which I would eventually have to do with each attribute on education (degree etc) or can I make a searchable method on Education and somehow "call" that from Person.searchable?

Thanks

It would be best if you keep the declaration of all the indexed fields for an specific model in the same place.

Also, you were doing a good job indexing :school_names, just do the same thing for the rest of the associations fields' that you want to index.
