i would like to apply toggle functionality on update could anyone开发者_Python百科 please help me.

There are numerous possibilities to achieve a toggle button. You may choose to change the JavaScript function your button executes, or the function may toggle the Rails action to call. I personally would go for a Rails action that knows how to toggle itself:

def toggle_action
  @model = Model.find param[:id]
  if @model.active?
    @model.active = false
    render :js => "alert('Active!');"
  else
    @model.active = true
    render :js => "alert('Inactive!');"
  end
end
