creating mutual friendships

I'm learning rails and I need some help. I want to add a social feature to a website where users can add and remove friends. I've joined two models, FriendRequest and Friendship, which both have their own controller and restful routes. I have the correct associations in the model and the correct controller actions. My issue is creating the user interface for this feature. I added a button which as such, <td class="info"><%= link_to 'Add Friend', friend_request_path(:friend_id => user), :method => :post %></td> This sends the friend request. My controller code has an index action which collects the requests as such: def create friend = User.find(params[:friend_id]) @friend_request = current_user.friend_requests.new(friend: friend) if @friend_request.save render :show, status: :created, location: @friend_request else render json: @friend_request.errors, status: :unprocessable_entity end end def update @friend_request.accept head :no_content end def index @incoming = FriendRequest.where(friend: current_user) @outgoing = current_user.friend_requests end def destroy @friend_request.destroy head :no_content end How do i create a UI to view the requests that are sent and received? So the user should navigate to the index action of the friend_requests controller and see all "pending" requests and "received" requests. So far I can send requests but I don't know how to accept them or view the requests. Any insight greatly appreciated!!
