Ruby on rails 如何使重定向包含名称而不是ID？

我使用的是Rails 5.1。在我的控制器中，我想重定向到我的“show”方法，如下所示

redirect_to(@organization)

但是我希望URL显示为

/organization/organization_name

而不是

/organization/primary_key_id

我该如何设置？我的组织模型中已经有一个字段“name”

编辑：根据要求，这是我的

PagesController

的索引方法

class PagesController < ApplicationController

  # Should be the home page
  def index
    worker_id = params[:worker_id]
    worker = Worker.find_by_id(worker_id)
    if worker && worker.organization
      redirect_to(worker.organization)
    else
      render :file => "#{Rails.root}/public/404", layout: false, status: 404
    end
  end

end

这是

app/model/strateum\u worker.rb

文件

  resources :organizations, :only => [:show] do
    post :update_work
    get :get_work
    get :mine
    get :poll
    post :submit
    get :home
    get :terms_of_use
  end

class StratumWorker < ApplicationRecord

  has_one :organization_worker
  has_one :organization, :through => :organization_worker

class StratumWorker:organization\u worker

在引擎盖下调用以生成id的方法是

to_param

因此，在您的情况下，为了获得所需的结果，您应该将其添加到您的

组织中

类：

class Organization < ApplicationRecord
  ...

  def to_param
    name
  end

  ...
end

班级组织

！！！警告-由于Rails也在另一端使用参数（例如，在show method

Organization.find（params[:id]）

中使用URL id），现在它将是

params[:id]=“some\u Organization\u name”

所以相应地更改实例查找-在

show

操作中，例如，使用

Organization.find\u by！（名称：params[：id]）

等等

---

至于路由错误，请确保

worker.organization

不是

nil

有一个gem-friendly_-id，它完全符合您的要求：

你加上

gem 'friendly_id'

然后安装

bundle

并运行

rails生成友好的\u id

和

rails db:migrate

到你的档案和

class Organization < ApplicationRecord
  extend FriendlyId
  friendly_id :name, use: :slugged
end

班级组织

那你的模特呢,

class OrganizationController < ApplicationController
  def show
    @user = Organization.friendly.find(params[:id])
  end
end

class OrganizationController

到你的控制器

这可以防止在Kkulikovski的答案中遇到问题，您必须确保正确查找内容。

好的，如果您不想使用任何gem，那么您可以不使用gem-like

class Model < ApplicationRecord
   def to_param  # overridden
      organization_name
    end
end

然后模型会像这样

validates_uniqueness_of :organization_name

class Model < ApplicationRecord
    validates_uniqueness_of :organization_name

    def to_param  # overridden
      organization_name
    end
end

class OrganizationWorker < ApplicationRecord

    belongs_to :stratum_worker 

    #=> Add code what you need like for URL which was the actual motive in this post
....

def index
    worker_id = params[:worker_id]
    worker = StratumWorker.find_by_id(worker_id)
    if worker && worker.organization_worker.present?
      #redirect_to(worker.organization_worker)
      redirect_to organization_path(worker.organization_worker)
    else
      render :file => "#{Rails.root}/public/404", layout: false, status: 404
    end
end

然后URL看起来像microsoft的

/10

看看这个方法。有无宝石的完整参考

用FriendlyId为漂亮的URL创建了一个插曲，你能帮我看看吗

我不认为发生了什么，但肯定是关系出了问题，你能这样检查一下吗

redirect_to(worker.organizations.first)
#=> OR
redirect_to organization_path(worker.organizations.first.id)

class StratumWorker < ApplicationRecord

    has_one :organization_worker
....

更新

我想

工人.组织

不知怎么找不到了，你能这样试试吗

if worker && worker.organizations.present?
   redirect_to(worker.organizations.first)
....

present

方法确保

worker.organizations

不为空

我不知道这种关系，你可以这样尝试，如果它不起作用，让我知道发生了什么，然后我强烈建议发布带有关系概念的模型

问题更新后更新2

首先，您不需要通过关系，因为它使用了太多的关系。你的关系是这样的，那么你的模型就是这样的

redirect_to(worker.organizations.first)
#=> OR
redirect_to organization_path(worker.organizations.first.id)

class StratumWorker < ApplicationRecord

    has_one :organization_worker
....

然后动作看起来像这样

validates_uniqueness_of :organization_name

class Model < ApplicationRecord
    validates_uniqueness_of :organization_name

    def to_param  # overridden
      organization_name
    end
end

class OrganizationWorker < ApplicationRecord

    belongs_to :stratum_worker 

    #=> Add code what you need like for URL which was the actual motive in this post
....

def index
    worker_id = params[:worker_id]
    worker = StratumWorker.find_by_id(worker_id)
    if worker && worker.organization_worker.present?
      #redirect_to(worker.organization_worker)
      redirect_to organization_path(worker.organization_worker)
    else
      render :file => "#{Rails.root}/public/404", layout: false, status: 404
    end
end

还有表演

OrganizationWorker.find(params:id)

我想问题现在会解决的。如果仍然存在错误，请再次阅读关系，直到清除关系概念

希望能有所帮助。

我不久前写了一篇文章详细介绍了这一点。我的大部分答案都将来自那里。这方面的相关Rails文档如下所示

快速定义：

• Slug:URL的一部分，用于识别记录，在您的案例中是

  organization\u name

• 主键：数据库记录的唯一标识符。这通常是并且应该是

  id

总结 如果键入

organization\u path（@organization）

，它将自动使用URL中的

id

属性。要调整为使用

组织名称

，您需要进行两项更改：

覆盖

routes.rb文件中的route参数

在模型中重写

to_param

方法

1.覆盖路由参数 目前，如果您运行

rails routes

您的路线看起来是这样的：

organizations       GET    /organizations(.:format)                     organizations#index
                    POST   /organizations(.:format)                     organizations#create
new_organization    GET    /organizations/new(.:format)                 organizations#new
edit_organization   GET    /organizations/:id/edit(.:format)            organizations#edit
organization        GET    /organizations/:id(.:format)                 organizations#show
                    PATCH  /organizations/:id(.:format)                 organizations#update
                    PUT    /organizations/:id(.:format)                 organizations#update
                    DELETE /organizations/:id(.:format)                 organizations#destroy

organizations       GET    /organizations(.:format)                                    organizations#index
                    POST   /organizations(.:format)                                    organizations#create
new_organization    GET    /organizations/new(.:format)                                organizations#new
edit_organization   GET    /organizations/:organization_name/edit(.:format)            organizations#edit
organization        GET    /organizations/:organization_name(.:format)                 organizations#show
                    PATCH  /organizations/:organization_name(.:format)                 organizations#update
                    PUT    /organizations/:organization_name(.:format)                 organizations#update
                    DELETE /organizations/:organization_name(.:format)                 organizations#destroy

edit_organization

和

organization

路径使用

id

作为参数来查找您的组织

使用此选项可覆盖管线参数

Rails.application.routes.draw do
  resources :organizations, param: :organization_name
end

现在

rails-routes

将显示您的路线如下所示：

organizations       GET    /organizations(.:format)                     organizations#index
                    POST   /organizations(.:format)                     organizations#create
new_organization    GET    /organizations/new(.:format)                 organizations#new
edit_organization   GET    /organizations/:id/edit(.:format)            organizations#edit
organization        GET    /organizations/:id(.:format)                 organizations#show
                    PATCH  /organizations/:id(.:format)                 organizations#update
                    PUT    /organizations/:id(.:format)                 organizations#update
                    DELETE /organizations/:id(.:format)                 organizations#destroy

organizations       GET    /organizations(.:format)                                    organizations#index
                    POST   /organizations(.:format)                                    organizations#create
new_organization    GET    /organizations/new(.:format)                                organizations#new
edit_organization   GET    /organizations/:organization_name/edit(.:format)            organizations#edit
organization        GET    /organizations/:organization_name(.:format)                 organizations#show
                    PATCH  /organizations/:organization_name(.:format)                 organizations#update
                    PUT    /organizations/:organization_name(.:format)                 organizations#update
                    DELETE /organizations/:organization_name(.:format)                 organizations#destroy

2.覆盖模型参数 默认情况下，

organization.to_param

将返回组织的

id

。这需要重写，请通过修改模型来执行此操作：

class Organization < ApplicationRecord
  def to_param
    organization_name
  end
end

您的路线如下：

 organization_update_work POST   /organizations/:organization_id/update_work(.:format)                                    organizations#update_work
    organization_get_work GET    /organizations/:organization_id/get_work(.:format)                                       organizations#get_work
        organization_mine GET    /organizations/:organization_id/mine(.:format)                                           organizations#mine
        organization_poll GET    /organizations/:organization_id/poll(.:format)                                           organizations#poll
      organization_submit POST   /organizations/:organization_id/submit(.:format)                                         organizations#submit
        organization_home GET    /organizations/:organization_id/home(.:format)                                           organizations#home
organization_terms_of_use GET    /organizations/:organization_id/terms_of_use(.:format)                                   organizations#terms_of_use
             organization GET    /organizations/:id(.:format)                                                             organizations#show

更改

参数

，如下所示：

  resources :organizations, :only => [:show], param: :organization_name do
    post  'update_work'
    get   'get_work'
    get   'mine'
    get   'poll'
    post  'submit'
    get   'home'
    get   'terms_of_use'
  end

将更改您的路线到

 organization_update_work POST   /organizations/:organization_organization_name/update_work(.:format)                     organizations#update_work
    organization_get_work GET    /organizations/:organization_organization_name/get_work(.:format)                        organizations#get_work
        organization_mine GET    /organizations/:organization_organization_name/mine(.:format)                            organizations#mine
        organization_poll GET    /organizations/:organization_organization_name/poll(.:format)                            organizations#poll
      organization_submit POST   /organizations/:organization_organization_name/submit(.:format)                          organizations#submit
        organization_home GET    /organizations/:organization_organization_name/home(.:format)                            organizations#home
organization_terms_of_use GET    /organizations/:organization_organization_name/terms_of_use(.:format)                    organizations#terms_of_use
             organization GET    /organizations/:organization_name(.:format)                                              organizations#show

这对你的重定向应该很好

您可以使用gemYa，该答案与您的设置不匹配。您可能还想共享

PagesController

代码。能否在其中包含OrganizationsController和show方法？我怀疑这就是您的

缺少所需密钥：[:id]

的原因。这不是来自路由吗？我的意思是，错误表明它甚至没有在控制器中执行任何代码，因为它不知道如何调用正确的方法。也许我错了。如果这确实是问题所在，我的路线将在问题中公布。您是否尝试过为（工人组织）添加

放置url\u

，并看到它正在生成您所期望的内容？您还需要对

名称

设置唯一性约束，并且根据

名称

中允许的内容，您可能希望在路由上添加一个

：约束

，以避免与格式等混淆。@Kkulikovskis，thx，但我仍然使用它
