私はこのクラスを持っています。

ユーザー：

class User < ActiveRecord::Base
  attr_accessible :email, :name
  has_many :berichten
end

カテゴリー：

class Category < ActiveRecord::Base
  attr_accessible :name
  has_many :berichten
end

Berichten :

class Berichten < ActiveRecord::Base
  attr_accessible :bericht, :user
  belongs_to :user
  belongs_to :category
end

私が最初にしたこと: rails generate active_admin:resource users そして、この出力が表示されます: create app/admin/users.rb

それから私はしました: ails generate active_admin:resource category そして、私はこの出力を見ます:

これを解決する方法は？

（ユーザー対ユーザー）rails generate active_admin:resource userの代わりに行う必要があります。rails generate active_admin:resource users

あなたがやったように、active_adminUsersはもちろん存在しないクラスを検索します。

したがってapp/admin/users.rb、上記のコマンドを削除して実行します。
