So I'm using has_and_belong_to_many association for two models (Article and Category). My header have link with dropdown menu where different categories appears. All my articles are on index page and I need to sort it depending what category it has so users could choose what they want to see. I guess I should do something in show action in category controller, but don't know what exactly. To solve this I played with different each iterations in my views and controller, but unfortunately it didn't help.
Any help will be appreciated
You can select articles with certain category with
selected_articles = Category.find_by_name("Name of category").articles
Or, if you don't know the name simply
selected_articles = Category.find(category_id).articles
