我最近將 gem Active Admin 添加到我的 rails 應用程式（使用 rails 5.2.6），我讓它與默認管理員一起作業，并且它按預期作業。但是我無法添加新管理員，AdminUser.create!(email: "[email protected]", password: "password", password_confirmation: "password")因為我收到rails aborted錯誤然后Don't know how to build task 'AdminUser.create!(email: "[email protected]", password: "password", password_confirmation: "password").
我已經嘗試使用rails db:migrate和運行我的種子。我也在使用設計寶石。
完整跟蹤：
rails aborted!
Don't know how to build task 'AdminUser.create!(email: example@gmail.com, password: password, password_confirmation: password)' (See the list of available tasks with `rails --tasks`)

正如我之前所說，所有其他 ActiveAdmin 功能都按預期作業，只是我無法創建新管理員。
我做錯了什么/可能忘記做什么？提前致謝。
uj5u.com熱心網友回復：
有幾種方法可以將該管理員添加到資料庫中：
rails console- 只需打開控制臺并執行AdminUser.create!(...).seeds.rb- 打開db/seeds.rb檔案并粘貼AdminUser.create!(...)。然后運行rake db:seed。請注意，rake db:seed多次運行將多次創建該管理員 - 最好有某種驗證或使用AdminUser.find_or_create_by(...)。- 耙任務-創建一個耙檔案
lib/tasks，名稱并不重要，但它應以結尾.rake（例如：update.rake）
task :add_admin do
AdminUser.find_or_create_by(email: "[email protected]", password: "password", password_confirmation: "password")
end
運行它rake add_admin。
如果你只想要你自己的管理員，你的本地機器，使用控制臺方法，否則選擇另外兩個，但確保 rake 任務是冪等的。
