我添加了通过应用程序中的按钮（链接）登录帐户的功能，但使用正确的路由，我得到一个错误：
/home/阿尔特姆/projects/blog/app/views/layouts/application.html.erb where line #44 raised：没有路由匹配{：action=>“show”，：controller=>“users”，：id=>nil，：locale=>：ru}，可能不匹配的约束：[：id]
但如果我手动输入链接（在浏览器的搜索字段中）-它工作（前提是id正确）
我的users_controller.rb：

class UsersController < ApplicationController
  def index
    @user = User.all
  end
  
  def show
    @user = User.find(params[:id])
    @user_posts = @user.posts
  end
end

我的链接（在application.html.erb中）：<%= link_to t('.Profile'), user_path(@user), class: "btn btn-outline-#{cookies[:theme] == "dark" ? "light": "dark"} mx-2" %>
我的路线：

Rails.application.routes.draw do
  scope "(:locale)", locale: /#{I18n.available_locales.join("|")}/ do
    root "posts#index"
    devise_for :users
    
    get 'set_theme', to: 'theme#update'
    
    resources :users
    resources :posts, only: [:show, :index]
    resources :tags, only: [:show]
    resources :categories, only: [:show]
    
    namespace :admin do
      resources :users
      resources :categories, except: [:show]
      resources :posts, except: [:show, :index]
    end
  end
end

如果您需要其他信息-请在备注中填写
我尝试了：users_path（@users）链接到index. html. erb。这是正确的
