Ruby on rails 4 重定向后如何将modelcreate中的变量传递给modelshow

我想在show.html中显示一个photo_link变量

因此，我在视图中单击“创建”，它将带我进入effectscreate

  def create
    @effect = Effect.new(effect_params)
    @effect.save
    @pid = params[:effect][:pid]
    @photo_link = apply_effect1(@pid)
    respond_with(@effect)
  end

当我检查日志时，我认为它被重定向到effectsshow，然后再显示到show.html

这是我的表演

  def show
    p "HIHI IM HERE"
    p params
    respond_with(@effect)
  end

我是否可以将@photo_链接传递到show.html

默认情况下，用will回复，将您重定向到show动作。您要做的是自定义respond_with的location参数，因此在本例中，您将被重定向到正确的位置，仍然是show操作，但带有额外的参数。看

我认为它是这样的：

respond_with(@effect, location: effect_show_path(@effect, @photo_link))
