这可能是一个非常棘手的问题，但我对 Rails 还很陌生，我正在开发我的第一个 Rails 应用程序。
这一切都是在未能创建仪表板功能时发生的。不知何故，所有仪表板控制器和模型都被删除了，我正在努力恢复它们。同样，rails_admin 已受到影响，将不再工作。
我试过捆绑安装，rake db:reset db:migrate 仍然出现这个错误..
ERROR: relation "dashboards" does not exist
LINE 8: WHERE a.attrelid = '"dashboards"'::regclass
这是我们在 /admin 访问管理面板的测试
require "rails_helper"
RSpec.feature "Visiting Admin Panel" do
before do
@Anag = User.create(first_name: "Anag", middle_initial: "A", last_name: "Avatar", email: "AnagAvatar@example.com", password: "Password", birthday: Date.new(1996), bio: "Lorem ipsum dolor sit amet, consectetur adipiscing elit. In vitae tincidunt orci. Quisque mauris

nfirmed_at: DateTime.new(2017))
end
scenario "with signed in user who's an admin" do
login_as(@Anag)
visit "admin"
expect(current_path).to eq "/admin"
expect(page).to have_content("Site Administration")
first(:link, "Assignments").click
expect(page).to have_content("List of Assignments")
end
end
这是rspec测试结果
