I came across the following situation An article has a history of friendly url being that the foreign key that represents the value of the article’s id in the table is called Friend url_id then in that case:
Article.joins(“INNER JOIN friends ON articles.id = friends.url_id”).where(“friends.url like ? ”, url)
if the column url_id was renamed for artigo_id would be easier
Article.joins(:friend).where(“friends.url like ? ”, url)
