I'm new to RoR and have only done light scripting and VB, so I'm sorry for the lack of knowledge. 我是RoR的新手，只做过轻脚本和VB，因此对知识的不足感到抱歉。

I have used the Rails_admin gem to add the admin feature to my ruby app. 我已使用Rails_admin gem将管理功能添加到我的ruby应用程序。 I then use rails to generate scaffold. 然后，我使用滑轨生成支架。 Ran rake to bring my db to the latest version. 跑耙使我的数据库到最新版本。 It creates the new table which I can access through http://localhost:3000/phonenumbers , but when I go to the http://localhost:3000/admin only my Users table is displayed. 它创建了一个新表，我可以通过http://localhost:3000/phonenumbers访问该表，但是当我转到http://localhost:3000/admin仅显示我的Users表。 Does rails_admin not automatically recognize all tables in the database? rails_admin不会自动识别数据库中的所有表吗？

Have you tried restarting your server? 您是否尝试过重启服务器？

I experienced a similar problem trying to add a new table, and rails admin on the same table, in one deploy. 我尝试在一个部署中尝试添加新表并在同一表上添加rails admin时遇到类似的问题。 This was because rails admin initializes routes for a table but the migration had not run yet. 这是因为rails admin初始化了表的路由，但是迁移尚未运行。

I had the same issue, I was so focused on my migration that i forgot to add the model. 我遇到了同样的问题，因为我非常专注于迁移，因此忘记添加模型。 You have to restart the rails app so Rails_Admin will pick up the new model. 您必须重新启动Rails应用程序，以便Rails_Admin将选择新模型。 It uses the model to derive the structure not the database. 它使用模型来导出结构而不是数据库。
