DBのCRUD-05(upload)修正

/views/main/edit.rhtml

<% form_for :member, @member, :url => {:action => 'update',:id => @member} do |form|%>
名前：<%= form.text_field :name %></p>
email：<%= form.text_field :email %></p>
<%= submit_tag '更新' %>
<% end %>

/app/controller/main_controllers.rb

  def edit
    @member = Member.find(params[:id])
  end
  def update
    @member = Member.find(params[:id])
    @member.attributes = params[:member]
    @member.save
  end

エラーがでるが、更新はできているはず。
