我的控制器中有以下内容:

def create
  group = Group.create(params[:group])
end

这在我的模型中:

validate :governance_style_change, :on => :update

. . . .

private

  def governance_style_change
    if self.governance_style_was != 3
      errors.add(:governance_style, I18n.t("group.errors.cannot_change_governance_style"))
    end
  end

出于某种原因,验证在create. 我做错了什么吗?
