Hi Yuri
The attribute should probably be of the id column, as that’s an integer (but I
presume code_12nc is a string? Sphinx doesn’t support multi-value string
attributes, nor does it support filtering on single-value string attributes).
So:
has product_digitalassets.id, :as => :product_digitalasset_ids
And then in your search, if you don’t have the id values, you’ll need to
translate 12NC codes to the ids:
ids = ProductDigitalasset.where(:code_12nc => params[:codes]).pluck(:id)
And then searching:
DigitalAsset.search :with => {:product_digitalasset_ids => ids}
Does this make sense?
