我遇到了同样的问题: Multi-step form in Rails 3 with Paperclip attachments

“TypeError in ...”“无法转储文件”

但是,我似乎无法解决答案中提到的解决方案:

unless @model.valid?
  @model.image.clear
  @model.image.queued_for_write.clear
end

我在哪里放上线?

这是我的控制器的代码:

  def new
    session[:member_params] ||= {}
    @member = Member.new(session[:member_params])
    @member.current_step = session[:member_step]
  end

  def create
    session[:member_params].deep_merge!(params[:member]) if params[:member]
    @member = Member.new(session[:member_params])

    @member.current_step = session[:member_step]
    if @member.valid?
      if params[:back_button]
        @member.previous_step
      elsif @member.last_step?
        @member.save if @member.all_valid?
      else
        @member.next_step
      end
      session[:member_step] = @member.current_step
    end

    if @member.new_record?
      render "new"
    else
      session[:member_step] = session[:member_params] = nil
      flash[:notice] = "Personal Data Sheet saved!"
      redirect_to @member
    end
  end

我在宣布@member之后尝试将它放在这里,但没有好处:

session[:member_params].deep_merge!(params[:member]) if params[:member]
@member = Member.new(session[:member_params])

unless @member.valid?
  @member.image.clear
  @member.image.queued_for_write.clear
end

P.S。 我想在这里提出问题: Multi-step form in Rails 3 with Paperclip attachments 但我不确定在同一问题/问题上发布后续问题是否可以。
