Question

我在rails 3项目中使用了twitter bootstrap，并且在成功创建帖子时无法显示flash消息。

这是代码 - 你能让我知道我做错了吗？

谢谢，

POSTS CONTROLLER

def create
    @post = Post.new(params[:post])
    @post.user = current_user

    respond_to do |format|
        if verify_recaptcha && @post.save
            format.html { redirect_to '/home'}
            format.json { render :json => @post, :status => :created, :location => @post }
            flash[:notice] = "Thank you, your request has been submitted."
        else
            format.html { render :action => "new" }
            format.json { render :json => @post.errors, :status => :unprocessable_entity }
        end
end

Answer 1

确保您的视图中包含类似内容（例如views / application.html.erb）

 <% flash.each do |name, msg| %>
    <%= content_tag :div, msg, :id => "flash_#{name}" %>
 <% end %>

Flash成功消息未显示
