def send_message
    @user = User.find(params[:user_id])
    @message=Message.new
    redirect_to send_message_path
end

    @post=Post.new
    @posts=@user.posts.reverse.paginate(:page => params[:page],:per_page => 10)

Answer 1

=link_to "Send message", [:send_message, @user]

and in your routes:

resources :users do
  post :send_message, :on => :collection
end
