Question

我正在使用两个Devise模型（Admin和User）进行Rails 5.2项目。我遵循了关于此Stack Overflow answer的建议，即在不破坏Devise的edit_admin_registration_path的情况下禁用Devise模型的注册。

应用routes.rb中建议的更改后，运行rails routes显示更改按预期工作，但是，当要编辑Admin（edit_admin_registration_path）时，我得到了错误：

NoMethodError in Admins::RegistrationsController#edit
undefined method `validatable?' for nil:NilClass

我怀疑问题在于链接的答案未使用具有作用域视图和控制器的多个Devise模型。

有什么想法吗？

我已将其添加到routes.rb：

devise_scope :admin do
  get "/sign_in" => "admins/sessions#new" # custom path to login/sign_in
  get "/sign_up" => "admins/registrations#new", as: "new_admin_registration" # custom path to sign_up/registration
end

devise_for :admins, skip: [ :registrations ], path: 'admins', controllers: { sessions: 'admins/sessions', registrations: 'admins/registrations' }
  as :admins do
    get 'admins/edit' => 'admins/registrations#edit', as: 'edit_admin_registration'
    put 'admins' => 'admins/registrations#update', as: 'admin_registration'
  end

查看表单：

<%= form_for(resource, as: resource_name, url: registration_path(resource_name), method: :put) do |f| %>
  <%= devise_error_messages! %>

  <%= f.label :email %><br />
  <%= f.email_field :email, autofocus: true, autocomplete: "email", class: "form-control" %>

  <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
    <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div>
  <% end %>

  <%= f.label :password %> <i>(leave blank if you don't want to change it)</i><br />
  <%= f.password_field :password, autocomplete: "off", class: "form-control" %>
  <% if @minimum_password_length %>
    <em><%= @minimum_password_length %> characters minimum</em>
  <% end %>

  <%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation, autocomplete: "off", class: "form-control" %>

  <%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br />
  <%= f.password_field :current_password, autocomplete: "off", class: "form-control" %>

  <%= f.submit "Update", class: "btn btn-success" %>
<% end %>

需要像这样配置路由（可以在this Stack Overflow answer中找到）：

devise_for :admins, :skip => [:registrations], path: 'admins', controllers: { sessions: 'admins/sessions', registrations: 'admins/registrations' }

devise_scope :admin do
  get 'admins/edit' => 'admins/registrations#edit', as: 'edit_admin_registration'
  put 'admins' => 'admins/registrations#update', as: 'admin_registration'
end
