Question

编辑3：我有一个用户和文档的嵌套设置，用于对用户进行身份验证当我试图访问我通过这个方法创建的链接时，会出现一个错误，它指向带有ActiveRecord :: RecordNotFound错误的控制器get_document方法

root :to => "users#index"

   resources :users do
   resources :documents
end

然后我尝试列出所有文件：

   @documents.each do |doc|

     link_to(doc.title, [@user, doc])

但是我在控制器中尝试访问私有get_user方法时遇到错误，这是执行此操作的核心方法

该文档属于用户，但只提供user_id我是否使用它？

private #get_user should not be called outside contoller
def get_user
  @user = User.find(params[:user_id])
end

错误：不应该为out side contoler调用私有方法

编辑：似乎是被调用的get_document方法......

def get_document
  @document = @user.documents.find(params[:id])
end

但文档引用正在传递给路由不是吗？

编辑2：文件的控制器代码：

 class DocumentsController < ApplicationController
before_filter :get_user
before_filter :get_document, :only => [:show, :update, :edit, :destroy] 
before_filter :authenticate_user!
load_and_authorize_resource

def new
  @document = @user.documents.build
end

def index
 if params[:tag]
  @documnets = Document.tagged_with(params[:tag])
 else
  @documents = Document.all
 end
end

def create
 @document = @user.documents.build(params[:document])
 if @document.save
  flash[:notice] = "Document has been created."
  redirect_to [@user, @document]
 else
  flash[:notice] = "Failed to create document."
  render :action => "new"
 end
end

def edit

end

def show

end

def update  
if @document.update_attributes(params[:document])
  flash[:notice] = "Update Complete"
  redirect_to [@user, @document]
else
  flash[:notice] = "Update Failed"
  render :action => "edit"
end
end

def destroy
 if @document.destroy
  flash[:notice] = "document deleted."
  redirect_to @user
 else 
  flash[:notice] = "Can't delete document"
  redirect_to [@user, @document]
 end
 end

private #get_user should not be called outside contoller
def get_user
  @user = User.find(params[:user_id])
end
public 
def get_document
  @document = @user.documents.find(params[:id])
end
end

显示的Rails嵌套路由错误
