NameError - 未初始化的常量

Question

我正在使用 Ruby on Rails 4，我的项目是关于一个 HR 应用程序。员工可以通过他的个人资料页面创建请假请求，但是我在他的个人资料页面中创建表单，我只想创建一个链接到请求控制器但我遇到了这个错误：

NameError in Employees#show Showing /home/user/workspace/hrapp/app/views/employees/show.html.erb where line #50 raised:

uninitialized constant Requests’

Extracted source (around line #50):

48 </p>
49 <%= link_to 'Edit', edit_employee_path(@employee) %> 
50 <%= link_to ‘My Annual Leave Requests’, controller:'requests' %>
51 <%= link_to 'Back', employees_path %>  

我尝试了这个解决方案：https://hackhands.com/rails-nameerror-uninitialized-constant-class-solution/

但它不起作用，我没有找到这个错误的通用答案。

这是 rake 路线：

user@snf-34155:~/workspace/hrapp$ rake routes

                  POST   /employees/:employee_id/requests(.:format)          requests#create
                  PUT    /employees/:employee_id/requests/:id(.:format)      requests#update

     new_employee GET    /employees/new(.:format)                            employees#new
    edit_employee GET    /employees/:id/edit(.:format)                       employees#edit
         employee GET    /employees/:id(.:format)                            employees#show
                  PATCH  /employees/:id(.:format)                            employees#update
                  PUT    /employees/:id(.:format)                            employees#update
                  DELETE /employees/:id(.:format)                            employees#destroy
             root GET    /                                                   welcome#index

我想我只需要编写正确的路线，但我尝试了其中的一些，但还是没有用。

请问，有人可以帮忙吗？

提前谢谢:)

app/controllers/requests_controller.rb

class RequestsController < ApplicationController
def index
  @employee = Employee.find(params[:employee_id])
  @request = @employee.requests.all
end

def show
  @employee = Employee.find(params[:employee_id])
  @request = @employee.requests.find(params[:id])
end

def new
  @employee = Employee.find(params[:employee_id])
  @request = @employee.requests.new
end

 def create
    @employee = Employee.find(params[:employee_id])
    @request = @employee.requests.create(request_params)
    redirect_to show_employee_path(@employee)
  end

  def destroy
    @employee = Employee.find(params[:employee_id])
    @request = @employee.requests.find(params[:id])
    @request.destroy
    redirect_to show_employee_path(@employee)
  end

  private
    def request_params
      params.require(:request).permit(:start_date, :end_date, :considerations)
    end
end

Answer 1

根据您发布的代码

</p>
<%= link_to 'Edit', edit_employee_path(@employee) %> 
<%= link_to ‘My Annual Leave Requests’, controller:'requests' %>
<%= link_to 'Back', employees_path %>  

‘My Annual Leave Requests’ 似乎使用了特殊的引号字符。您是否偶然从其他来源复制并粘贴了该内容？

我可以看到的一个修复是手动将引号更改为使用双引号 "

我注意到您的错误未初始化常量请求的末尾还包含一个引号。您是否也尝试修复控制器：“请求”？
