Rails与IE的问题

Question

我在实际的IE中遇到了Rails 4.2.1和Ruby 2.1应用程序的几个问题。如果我将某些内容保存到数据库并进行重定向，则值将在数据库中保存两次。

有没有人也有这个？

将Methode保存在控制器中：

if request.post?
  @question.attributes = params[:question]
  if @question.save
    flash.now[:notice] = t("flash.saved")
    update_answers params
    redirect_after_save @question
  end
end


 def update_answers params
if !params[:add].nil?
  params[:add].each do | id, data |
    answer = Answer.new
    data[:question_id] = @question.id
    answer.update_attributes data
  end
end
end


def redirect_after_save q

if params[:action_after_save] == 'back'
  flash[:notice] = I18n.t("flash.saved")
  redirect_to :controller => :lessons, :action => :edit, :id => q.lesson_id
end
if params[:action_after_save] == 'new'
  flash[:notice] = I18n.t("flash.saved")
  redirect_to :action => :new, :id => q.lesson_id
end
if params[:action_after_save] == 'test'
  flash[:notice] = I18n.t("flash.saved")
  redirect_to :action => :test, :id => q.id
end
end
