按道理在 Rails 中这两行代码不应该是等价的么 redirect_to @user和redirect_to user_url(@user)，但是在我在 Rails7 中使用时，两者重定向地址貌似不一样，不知道是什么原因导致的。

• redirect_to @user会重定向到http://localhost:3000/users/id

• redirect_to user_url(@user)会重定向到http://localhost:3000/users.id

部分代码

• new.html.erb（参考Error: Form responses must redirect to another location多套了一个turbo_frame_tag）

<%#  用户注册页面 %>
<%= provide(:title, "Sign up") %>
<h1>Sign up</h1>

<div class="row">
  <div class="col-md-6 mx-auto">
    <%= turbo_frame_tag "post" do %>
      <%= form_for(@user, url: signup_path) do |f| %>
        <%= render 'shared/error_messages' %>

        <%= f.label :name, class: "form-label" %>
        <%= f.text_field :name, class: "form-control" %>

        <%= f.label :email, class: "form-label mt-3" %>
        <%= f.email_field :email, class: "form-control" %>

        <%= f.label :password, class: "form-label mt-3" %>
        <%= f.password_field :password, class: "form-control" %>

        <%= f.label :password_confirmation, "Confirmation", class: "form-label mt-3" %>
        <%= f.password_field :password_confirmation, class: "form-control" %>

        <div class="d-grid gap-1 mt-4">
          <%= f.submit "Create my account", class: "btn btn-outline-primary" %>
        </div>
      <% end %>
    <% end %>
  </div>
</div>

• UsersController.rb

  def create
  @user = User.new(user_params)
  
  # respond_to do |format|
  #   if @user.save
  #     # redirect_to @user
  #     format.html { redirect_to @user, notice: 'User account was successfully created.' }
  #     format.json { render :show, status: :created, location: @user }
  #   else
  #     # 处理注册失败的情况
  #     format.html { render :new }
  #     format.json { render json: @user.errors, status: :unprocessable_entity }
  #   end
  # end
  
  if @user.save
    # redirect_to users_url(@user)
    redirect_to @user
  else
    render 'new'
  end
  end
  

• routes.rb

  Rails.application.routes.draw do
  # Defines the root path route ("/”）
  root "static_pages#home"
  # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html
  get '/help', to: 'static_pages#help'
  get '/about', to: 'static_pages#about'
  get '/contact', to: 'static_pages#contact'
  #用户注册路由
  get '/signup', to: 'users#new'
  post '/signup', to: 'users#create'
  resources :users
  end
  

有大佬知道这是什么原因导致的么？
