在IE中的Rails問題 - 在數據庫中雙重存儲

Question

在IE中測試時，我遇到了Rails 4.2.1和Ruby 2.1應用程序的幾個問題。如果我將某些內容保存到數據庫並執行重定向，則這些值將在數據庫中保存兩次。

有沒有人有這個呢？

保存了Methode在控制器：

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 

我沒有使用turbolinks

。

查看代碼：

<%= f.submit t("main.save"), :icon => :save %> 
<%= t("question.or_save_and") %>: 
<% [[t('question.after_save_back'), 'back'], 
    [t('question.after_save_new'), 'new'], 
    [t('question.test_question'), 'test']].each do |it| %> 
    <%= f.submit(it.first, :disable_with => "saving", 
      :onclick => "$('#edit_question').append('<input type=\"hidden\" name=\"action_after_save\" value=\"" + it.second + "\" />');", 
      :icon => :save) %> 
<% end %> 

這是被保存時調用的代碼。

def multiple_choice 
@question = Question.find params[:id] 
return false unless check_authorization @question 
add_edit_breadcrumbs @question 

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

整個代碼在IE調用兩次......

添加屬性：

disable_with: 'button-text' 

的提交按鈕解決了這個問題（從上述評論）。
