在不传递参数的情况下在ActiveAdmin中切换语言（语言环境）

I want to be able to switch my locale in an ActiveAdmin app of mine. So far I've followed this guide on switching-locale, which actually mentions the problem I'm having:

我希望能够在我的ActiveAdmin应用程序中切换我的语言环境。到目前为止,我已经遵循了关于切换区域设置的本指南,它实际上提到了我遇到的问题:

You will notice, however, that all links keep the default locale of your app.

但是,您会注意到所有链接都保留了应用的默认语言环境。

So in my case, once I switch the locale, the urls stay

所以在我的情况下,一旦我切换了语言环境,网址就会保留

localhost:3000/en/admin/users instead of

localhost:3000 / en / admin / users而不是

localhost:3000/de/admin/users

The guide also proposes a solution:

该指南还提出了一个解决方案:

You can override this default locale by passing the locale to all _path methods.

您可以通过将语言环境传递给所有_path方法来覆盖此默认语言环境。

But this seems error-prone and quite a lot of work.

但这似乎容易出错并且工作量很大。

So looks like ActiveAdmin uses I18n.locale once to create all the urls and does not consider changes to I18n.locale after that.

所以看起来ActiveAdmin使用I18n.locale创建所有URL并且之后不考虑对I18n.locale的更改。

Meaning if you this in your ApplicationController:

如果您在ApplicationController中有这个意思:

def set_locale
  I18n.locale = params[:locale] || I18n.default_locale
end

I've tried overriding

我试过压倒一切

ActiveAdmin::Helpers::Routes.default_url_options

in my ApplicationController, which did not help.

在我的ApplicationController中,没有帮助。

Does anyone have an idea how I could resolve this issue?

有谁知道如何解决这个问题?

Edit:

I also set these and tried different variations of the scope method.

我也设置了这些并尝试了范围方法的不同变体。

Routes

scope '(/:locale)', locale: /en|de/, defaults: { locale: I18n.locale }
  ActiveAdmin.routes(self)
end

ApplicationController

def default_url_options(options={})
  { locale: I18n.locale }.merge options
end

2 个解决方案

Ok so I've finally figured out what was going on.

好的,我终于弄清楚发生了什么。

I originally followed the rails guide and set my routes.rb:

我最初遵循rails指南并设置我的routes.rb:

# config/routes.rb
scope "/:locale" do
  resources :books
end

which resulted in an error like:

导致如下错误:

No route matches {:action=>"index", :controller=>"admin/users"} missing required keys: [:locale]

没有路由匹配{:action =>“index”,:controller =>“admin / users”}缺少必需的密钥:[:locale]

this was "fixed" by setting

这是通过设置“修复”

scope ':locale', defaults: { locale: I18n.locale } do
  ActiveAdmin.routes(self)
end

as suggested in the current version of the Switching locale guide. But this has the side-effect of all subsequent url_helpers using this locale for url generation. BTW at least one other person ran into this.

正如当前版本的“切换区域设置指南”中所建议的那样。但这会产生所有后续url_helpers的副作用,使用此区域设置生成url。顺便说一句,至少有一个人碰到了这个。

My current work-around can be found here:

我目前的解决方法可以在这里找到:

 lib/active_admin/helpers/routes/url_helpers.rb
 def self.default_url_options         
    (Rails.application.config.action_mailer.default_url_options.merge({locale: ::I18n.locale})) || {}
 end

Now urls are generated as expected.

现在,URL按预期生成。

First of all you need define :locale scope as optional, this can be done with this code:

首先,您需要定义:locale scope as optional,这可以使用以下代码完成:

scope '(:locale)' do
    #your routes
end

After in ApplicationController put that code for enable default scoping:

在ApplicationController之后,将该代码放入启用默认范围:

def default_url_options(options={})
    options.merge({locale: I18n.locale})
  end
