问如何在表单错误后保留部分在同一页上？

EN

def page_title
  "#{@page_title}"
end

<% unless @page_title.blank? %>
<div class="row">
   <div class="page-header span12">
      <h1><%= @page_title %></h1>
   </div>
</div>
<% end %>

def new
  @business = Business.new
  @page_title = "Add Business"
end

def create
  @business = Business.new(params[:business])
  if @business.save
    redirect_to :back, :notice => "This Business was successfully added."
  else
    render :new, :notice => "It seems there was an error. Please try again."
  end
end
