干燥控制器动作

Question

我有一个ContentController，我在这两个动作中执行类似的功能。如何减少这些函数的代码重复？

def like
  like = Like.create(like: params[:like], user: current_user, content: @content)
  if like.valid?
    flash[:success] = "Your vote was successful!"
    redirect_to :back
  else
    flash[:danger]= "You can like a content only once"
    redirect_to :back
  end
end

def review
  review = Review.create(body: params[:body], user: current_user, content: @content)
  if review.valid?
    flash[:success] = "Your review was successful!"
    redirect_to :back
  else
    flash[:danger]= "You can review a content only once"
    redirect_to :back
  end      
end

Answer 1

您可以通过这种方式实现它，但请确保您的参数（如/ review）与操作名称相同。

 def common_action(action)
     object = Object.const_get(action.camelcase).create(action.to_sym => params[action.to_sym])
 end
