我有以下控制器

class DashboardController < ApplicationController
  before_action :authenticate_user!, except: [:show]
  before_action :set_user, only: [:show]
  def index
    @should_render_navbar = true
  end

  def show
    redirect_to dashboard_path if @user.nil?
  end

  private

  def set_user
    # localhost:3000/1
    @user = User.find_by_id(params[:id])
  end
end

有以下路线

Rails.application.routes.draw do
  devise_for :users
  get 'dashboard', to: 'dashboard#index'
  root 'dashboard#index'

  # Allows us to use user_path(user) to get the URL for a user's profile page
  get ':id', to: 'dashboard#show', as: :user
  # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html

  # Defines the root path route ("/")
  # root "articles#index"
end

当我手动输入localhost：3000/2时的控制台输出

我不知道为什么我被重定向到 Jmeter 板，特别是因为参数找到了用户
