How to define a Rails Helper for one specific action?

I have a LabelTagHelper with a custom method label_tag, but I need this method only in the new , create , edit and update .

Is there a way to define this helper only for a specific action? Something like helper :label_tag, :only => [:new, :create, :update, :destroy]? Or is it safe to call self.class.helper :label_tagin the before_filter file?

Helpers rails should be just formatting. Think of it the same way as functions that decorate your presentation level (view)

: before_filter . .

      #user custom implementation
    else
      super
