Подтвердить что ты не робот

Модель комментариев ActiveAdmin не работает должным образом

Я создал блог, выполнив "Начало работы с Rails" . И затем я следую учебнику здесь, чтобы попробовать ActiveAdmin: http://activeadmin.info/documentation.html.

Он отлично работает для моделей Post и Tag (я вошел в систему и создал/добавил/отредактировал материал), но не модель комментария.

rails generate active_admin:resource Comment

create  app/admin/comments.rb

Затем, когда я пытаюсь запустить сервер, я получаю следующее:

ОТВЕТЫ

Ответ 1

Похоже на ошибку (у ActiveAdmin уже есть встроенная модель/класс Comment): https://github.com/gregbell/active_admin/issues/64

Возможным обходным решением может быть предоставление вашей модели Comment другого имени внутри app/admin/comments.rb:

ActiveAdmin.register Comment, :as => "PostComment" do

Ответ 2

попробуйте это

запустить в терминале

rails g active_admin:resource ActiveAdmin::Comment

добавить следующие строки в приложение/администратор/active_admin_comment.rb

ActiveAdmin.register ActiveAdmin::Comment, :as => "Comment" do
end

после этого отредактируйте config/initializers/active_admin

[...]
  config.comments_registration_name = "OldComment"
  config.show_comments_in_menu = false
[...]

И теперь у вас есть возможность настроить комментарии в приложении /admin/active _admin_comment.rb но я до сих пор не нашел решение добавить команды : update и : destroy

Ответ 3

У меня была такая же проблема с версией 1.0.0.pre, но, к счастью, вы можете полностью отключить комментарии ActiveAdmin с помощью config в active_admin.rb, тогда вам больше не нужно будет использовать псевдоним вашей собственной модели комментариев, как указано выше.

конфигурации/Инициализаторы/active_admin.rb

  ...
  # == Admin Comments
  #
  # This allows your users to comment on any resource registered with Active Admin.
  #
  # You can completely disable comments:
  config.allow_comments = false
  #

Он также указан в документах: https://github.com/gregbell/active_admin/blob/master/docs/1-general-configuration.md#comments

Ответ 4

Ответ Дилана - отличное начало. В дополнение к его, мне нужно было перезаписать методы/ресурсы контроллера.

app/admin/comments.rb

ActiveAdmin.register Comment, as: 'QuestionComment' do
   controller do
     defaults resource_class: Comment, collection_name: 'comments', instance_name: 'comment'
   end
end

В принципе, вы просто перезаписываете значения по умолчанию унаследованного контроллера ресурсов (https://github.com/josevalim/inherited_resources#overwriting-defaults)

(да, это все еще проблема в 2014 году даже в версии 1.0.0, но кажется, что они хотят исправить ее из чтения проблем github)
