Rails includes with scope

August 17, 2023 by Tarik

I think the best solution would be:

Author.includes(:articles).where(:articles=>{published: true}).find(params[:author_id])

Or you can create scope:

class Author < ActiveRecord::Base 
    scope :with_published_articles, -> { includes(:articles).where(articles: { published: true}) }
end

and then:

Author.with_published_articles.find(params[:author_id].to_s)
