没有匹配的路由{：action=〉“显示”，：controller=〉“用户”}
在rails中使用此格式的条件current_page。尝试不在users/show路径中呈现导航栏，但它应该在站点的其余部分可见。需要注意的是，users/show URL已在routes.rb中配置为不在URL中显示“/users/”文件夹，因此它看起来像“mysite.com/username”

<% if current_page?(controller: 'users', action: 'show') %>
    no navbar
    <% else %>
    <%= render partial: "shared/navbar" %>
    <% end %>

第一个条件工作正常，但是当我到达一个应该匹配'else'条件的页面时，例如我的root_path，我得到了这个错误：

ActionController::UrlGenerationError in Dashboard#show
    Showing /Users/javier/Desktop/rails-apps/testtradus3/app/views/shared/_navbar.html.erb where line #1 raised:

    No route matches {:action=>"show", :controller=>"users"}

我的路线rb看起来像这样

# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
    Rails.application.routes.draw do
    ...

      # This removes '/users/' from user/show URI
      resources :users, path: '', :only => [:show]

      # User account
      devise_for :users,
        controllers: {
          omniauth_callbacks: "users/omniauth_callbacks",
          registrations: "users/registrations",
          sessions: "users/sessions"
        }
      devise_scope :user do
        get "session/otp", to: "sessions#otp"
      end

      resources :users do
        resources :builduser, controller: 'users/builduser'
      end

    ...

    end

这将返回以下轨道路径：
用户GET /用户（.：格式）用户#索引POST /用户（.：格式）用户#创建
我试过删除routes.rb中的自定义路径，比如resources：users，它返回这些路径users GET /users（.：format）users#index POST /users（.：format）users#create

GET    /users(.:format)                                                                                  users#index
          POST   /users(.:format)                                                                                 users#create
          GET    /users/new(.:format)                                                                              users#new
          GET    /users/:id/edit(.:format)                                                                         users#edit
          GET    /users/:id(.:format)                                                                              users#show

我的用户控制器.rb

class UsersController < ApplicationController

        def index
            @users = User.all
        end

        def show            
            @user = User.friendly.find(params[:id])
            @order = Order.new
        end

        def create
            @user = User.new(user_params)
            
            respond_to do |format|
                if @user.save
                # format.html { redirect_to @order, notice: "Order was successfully created." }
                # Added this one below:
                format.html { redirect_to user_builduser_index_path(@user)}
                format.json { render :show, status: :created, location: @user }
                else
                format.html { render :new, status: :unprocessable_entity }
                format.json { render json: @user.errors, status: :unprocessable_entity }
                end      
            end
        end
    ..
    end
