acts_as_votable thumbs up/down buttons

Question

I installed the acts_as_votable gem, it works in the console like it should (like it says in the documentation). So my question is how to set up a form for upvote and downvo

Answer 1

One way to do this is to add your own controller actions for up- and downvotes. I'm assuming you have a current_user method available in your controller.

# pictures_controller.rb
def upvote
  @picture = Picture.find(params[:id])
  @picture.liked_by current_user
  redirect_to @picture
end

def downvote
  @picture = Picture.find(params[:id])
  @picture.downvote_from current_user
  redirect_to @picture
end

# config/routes.rb

resources :pictures do
  member do
    put "like", to: "pictures#upvote"
    put "dislike", to: "pictures#downvote"
  end
end

# some view

<%= link_to "Upvote", like_picture_path(@picture), method: :put %>
<%= link_to "Downvote", dislike_picture_path(@picture), method: :put %>
