Example -
class Group < ApplicationRecord
has_many :options
accepts_nested_attributes_for :options
end
class Option < ApplicationRecord
belongs_to :group
validates :name, uniqueness: { scope: :group_id }
end
If I try to create a new group, I don’t want to create duplicate options with same name for the same group. Other groups may have options with same name.
Group.create({
age: 10,
option_attributes: [
{name: "Red"},
{name: "Red"},
],
Is there a way to do this in Rails ?
I don’t want to raise duplication errors, I want to create a unique option silently.
