Rails create or update for associated records

Question

I have this example code which raises a "Duplicate Expection". Instead, I want just to skip if a duplicate exists. (1..10).each do |page| group.products << [{id: 1, title: "Example A"}, {id: 2, title: "Example B"}] group.save end The product array is static just for this example, what matter is that it has ID's, so products exist in the database. The problem is when I assign a product that I have already assigned in the past which raise a "Not Unique exception". In this scenario, I would just skip the association. How is that possible?

Answer 1

You could use create_with in combination with find_or_create_by: (1..10).each do |page| group.products << Product.create_with(title: "Example A").find_or_create_by(id: 1) group.products << Product.create_with(title: "Example B").find_or_create_by(id: 2) group.save end
