I have an Artwork model that is associated to the models Subject, Location, Keyword, Style, and Medium by HABTM. I also have an association to an Artist model with one-to-many. Here's my error I keep getting:
>rake ts:index
Generating configuration to /Users/<user>/Developer/jtodd/jtoddgalleries/config/development.sphinx.conf
rake aborted!
NoMethodError: undefined method `klass' for nil:NilClass
Here's my indices file:
ThinkingSphinx::Index.define :artwork, :with => :active_record do
indexes title, :sortable => true
has jtg
has width
has height
has subject.id, :as => :subject_ids
has location.id, :as => :location_ids
has keyword.id, :as => :keyword_ids
has artist.first_name, :as => :artist_first
has artist.last_name, :as => :artist_last
has style.id, :as => :style_ids
has medium.id, :as => :medium_ids
end
I can't figure out why I keep getting different errors. I may not have a firm grasp on fields vs. attributes and maybe that's where I'm going wrong. Any help is greatly appreciated, thank you!
I'm presuming your associations are all listed in your Artwork model with plural names? It needs to be the same in your index definition.
As for fields vs attributes, a good rule of thumb is that anything you expect a user to type in and get results for should be a field. So, I'm guessing you'd want artist first and last names as fields.
Thus, an amended index definition:
ThinkingSphinx::Index.define :artwork, :with => :active_record do
indexes title, :sortable => true
indexes artist.first_name, :as => :artist_first
indexes artist.last_name, :as => :artist_last
has jtg
has width
has height
has subjects.id, :as => :subject_ids
has locations.id, :as => :location_ids
has keywords.id, :as => :keyword_ids
has styles.id, :as => :style_ids
has mediums.id, :as => :medium_ids
# or is it media?
end
If you're still getting an error, can you run rake ts:index --trace and share the backtrace with us? :)
