...tables. Each listing can have many agents and each agent can have many listings. In the agents_listings table I have a column called ''is_primary_agent'' which denotes if the agent is responsible for the listing - only one agent can be primary. At the moment I use this in my listing_controller''s view action: @listing = Listing.find(@params[:id], :include => [ :agents, :listing_images, :listing_pdfs ] ) What is the best, most efficient way to have this attribute appear against my agents? TIA, Matt.
