使用命名空间路由时出现路由错误
当路由被命名时，你如何处理form_for？我收到了一些我真正期望得到的奇怪的路线错误。
例如，假设您有一个名为 Admin::CompaniesController 的控制器，位于 你的routes.rb中的 :admin 命名空间：
namespace :admin do
resources :companies
end
大多数事情都工作正常，但是当我渲染新表单时，我收到错误。这是代码：
<%= simple_form_for(@company, :url => admin_company_path(@company)) do |f| %>
这是错误消息：
ActionView::Template::Error: No route matches {:action=>"show", :controller=>"admin/companies", :id=>#<Company id: nil, name: nil, phone_number: nil, address: nil, postal_code: nil, is_enabled: true, courses_created: 0, province_id: nil, theme_id: nil, payment_plan_id: nil, created_at: nil, updated_at: nil>}
如何让 Rails 在这里发挥良好作用？我显然想要一个用于编辑的网址，另一个用于新表单的网址。通常，我什至不需要将 :url 放入 form_for 语句中，但由于嵌套，我被迫这样做。
我现在不知道在这里做什么，至少不知道该怎么做。
How do you deal with form_for's when the routes are namespaced? I am getting some weird route errors that I really expect to get.
For example, let's say you have a controller called Admin::CompaniesController in
your :admin namespace in your routes.rb:
namespace :admin do
resources :companies
end
Most things work just fine, but I get an error when I render a new form. Here's the code:
<%= simple_form_for(@company, :url => admin_company_path(@company)) do |f| %>
And here's the error message:
ActionView::Template::Error: No route matches {:action=>"show", :controller=>"admin/companies", :id=>#<Company id: nil, name: nil, phone_number: nil, address: nil, postal_code: nil, is_enabled: true, courses_created: 0, province_id: nil, theme_id: nil, payment_plan_id: nil, created_at: nil, updated_at: nil>}
How can I get rails to play nice here? I obviously want one url for edits, and another for new forms. Usually, I'd never even have to put :url in my form_for statements, but because of the nesting, I am forced to.
I have no idea what to do here now, at least not elegantly.

尝试使用 simple_form_for([:admin, @company]) do |f|
Try using
simple_form_for([:admin, @company]) do |f|我相信我只需要在路径末尾将路径复数，如下所示：
这不是我所期望的。我只是猜测而已。这不是有效的路线或任何东西，但它似乎适用于 put 和 posts。
I believe I just have to pluralize the path at the end of the path, like this:
This is not what I would have expected. I just guessed at it. This is not a valid route or anything, but it seems to work for puts and posts.
