问题 Basically I want to update each table column for a Model in Rails 5. str = "abc---def" str.split('---').map do |a| Foo.where(product_id:1).update_all(bar: a) end Old object would be like: [ [0] { product_id: 1, ..., bar: "xxx", ... }, [1] { product_id: 1, ..., bar: "xxx", ... } ] New should be like: [ [0] { product_id: 1, ..., bar: "abc", ... }, [1] { product_id: 1, ..., bar: "def", ... } ] But what I got is bar: "def" for each.
