🏗️ Presence Validation on Nested Attributes​

Ensure that nested attributes are present when using forms. Pair accepts_nested_attributes_for with validates_presence_of on the child model for reliable form errors.

class Survey < ApplicationRecord
  has_many :questions
  accepts_nested_attributes_for :questions
end

class Question < ApplicationRecord
  belongs_to :survey
  validates :content, presence: true
end
