如何在保存Ruby on Rails之前修改记录

user = User.find(1)
user.update_attribute(:name, "New Name")

user = User.find(1)
user.update(name: "New Name", email: "new_email@example.com")

user = User.find(1)
user.assign_attributes(name: "New Name", email: "new_email@example.com")
user.save

user = User.find(1)
user.attributes = { name: "New Name", email: "new_email@example.com" }
user.save

user = User.find(1)
user.update_columns(name: "New Name", email: "new_email@example.com")

class User< ApplicationRecord
  before_save :encrypt_password

  def encrypt_password
    self.password = Digest::SHA256.hexdigest(password)
  end
end
