编辑3：当我尝试访问通过此方法创建的链接时，我为用户和文档设置了嵌套设置，该设计用于对用户进行身份验证

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])

但是我在尝试访问控制器中的私有 get_user 方法时遇到错误，这样做的正确方法是什么

该文档属于一个用户，但只给出了 user_id 我要使用它吗？

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

错误：不应为外部控制器调用私有方法

编辑：似乎是被调用的 get_document 方法......

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

但是文档引用正在传递给路由不是吗？

编辑 2：文档的控制器代码：

 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
