Question

我有用户和广告系列模型。我在用户和网址下嵌套广告系列如下所示：

http://localhost:3000/user-slug/campaign-slug

路线：

resources :users, :path => '' do
  resources :campaigns, :path => ''
end

广告系列模型：

class Campaign < ActiveRecord::Base
  ...
  extend FriendlyId
  friendly_id :title, use: :history
  ...
end

我的用户模型没有使用历史记录。

广告系列控制器（来自friendly_id指南）：

class CampaignsController < ApplicationController
  before_filter :find_campaign

  def show
    @campaign = Campaign.friendly.find(params[:id])
  end

  private

  def find_campaign
    @campaign = Campaign.friendly.find(params[:id])

    # If an old id or a numeric id was used to find the record, then
    # the request path will not match the post_path, and we should do
    # a 301 redirect that uses the current friendly id.
    if request.path != campaign_path(@campaign)
      return redirect_to @campaign, :status => :moved_permanently
    end
  end
end

当我访问旧slu to以触发重定向时，我收到此错误：

ActionController::UrlGenerationError in CampaignsController#show

No route matches {:action=>"show", :controller=>"campaigns", :format=>nil, :id=>nil, :user_id=>#<bunch of other stuff in here>} missing required keys: [:id]

我不确定如何调整重定向方法以使其正常工作。

管理以使其与此一起使用：

  def find_campaign
    @campaign = Campaign.friendly.find(params[:id])
    @user = @campaign.user

    # If an old id or a numeric id was used to find the record, then
    # the request path will not match the campaign_path, and we should do
    # a 301 redirect that uses the current friendly id.
    request_slug = params[:id]
    if request_slug != @campaign.slug
      return redirect_to user_campaign_path(@user, @campaign), :status => :moved_permanently
    end
  end

我没有比较请求路径，而是比较了斜杠之前没有部分的请求slug。我需要重定向到正确的路线user_campaign_path。

如何在嵌套资源中使用friendly_id历史记录
