Question

我确定我遗漏了一些基本的东西，但我有一个模型用户属于一个具有名称属性的公司模型。

如何按公司名称对所有用户进行排序？

@users = User.all #sort this collection in order of the associated company's name

class User < ActiveRecord::Base
    belongs_to :company
end

class Company < ActiveRecord::Base
end

  create_table "users", force: :cascade do |t|
    t.string   "name"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.integer  "company_id"
  end

  create_table "companies", force: :cascade do |t|
    t.string   "name"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end
