how to sort joined tables?

[Zlodiak Zlodiak]

help please write orm-request.

tables:
users:
id: integer
name: varchar

posts:
id: integer
title: varchar
user_id: integer
views: integer

models:
User:
class User < ActiveRecord::Base
has_many :posts, dependent: :destroy
end

Posts:
class Post < ActiveRecord::Base
belongs_to :user
end

controller:
def popular_diary
@users =
User.joins(:posts).group_by(:user_id).order('SUM(posts.views)')
end

html:
<% @users.each do |user| %>
<div class="row">
<%= link_to user_posts_url(user.id) do %>
<div><%= user.name %></div>
<% end %>
</div>
<% end %>

I need that all users hatched in a certain order. order ('SUM
(posts.views)

The problem is that the screen displays the following error message:
wrong number of arguments (0 for 1)
