Ruby on rails 未初始化的常量用户：：CompanyRate

我是rails的新手。我正在尝试生成一个页面表单。但是我犯了这个错误

我不明白我的问题在哪里

这是显示错误，并在此行中突出显示

@companies_rates =@user.companies_rates

这里我将有userpage、Companys_rate和page3，其中每个页面都有用户id，Companys rate有一列，第3页中也有相同的列。现在我要分别显示公司的费率和第3页

NameError in UsersController#show 

uninitialized constant User::CompaniesRate 

 @user = User.find(params[:id])
@companies_mines= @user.companies_mines
**@companies_rates =@user.companies_rates**
@title=@user.name
end

这是我的用户控制器

class UsersController < ApplicationController
  before_action :signed_in_user,
                only: [:index, :edit, :update, :destroy, :following, :followers]
  before_action :correct_user,   only: [:edit, :update]
  before_action :admin_user,     only: :destroy

  def index
    @users = User.paginate(page: params[:page])

  end

  def show
    @user = User.find(params[:id])
    @companies_mines= @user.companies_mines
    @companies_rates =@user.companies_rates
    @title=@user.name

  end



  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to skillable"
      redirect_to @user

    else
      render 'new'

    end
  end

      redirect_to @user

    else
      render 'edit'

有人能告诉我什么是我的问题以及如何解决它吗

将型号名称更改为CompanyRate。型号名称应为单数

如果可以，发布您的用户型号。您是否在用户和公司费率之间建立了关系？公司费率是否为模型？请使用更多信息更新您的问题。您好，我已添加了更多信息。
