I've problem with acts_as_votable gem. I have simple forum app and I want to have feature to vote up and down posts. I used for this acts_as_votable gem. I've added to posts controllers two methods:

def upvote
    @post = post.find(params[:id])
    @post.liked_by current_user
    redirect_to forum_topic_path(@post.topic.forum, @post.topic)
  end

  def downvote
    @post = post.find(params[:id])
    @post.downvote_from current_user
    redirect_to forum_topic_path(@post.topic.forum, @post.topic)
  end

My routes is :

  resources :topics, except: :index do
    resources :posts do
      member do
        put "like", to: "posts#upvote"
        put "dislike", to: "posts#downvote"
      end
    end
  end

And in my topic show action view i have the followings links:

= link_to "Upvote", like_topic_post_path(post.topic.id,post.id, method: :put)
= link_to "Downvote", dislike_topic_post_path(post.topic.id,post.id, method: :put)

When I'm trying to click upvote or downvote i have been redirected to: http://localhost:3000/topics/104/posts/55/like?method=put and i have following error: No route matches [GET] "/topics/104/posts/55/like" What's wrong?

Try "GET" method instead of "PUT" as shown below,

resources :topics, except: :index do
    resources :posts do
      member do
        get "like", to: "posts#upvote"
        get "dislike", to: "posts#downvote"
      end
    end
  end
