Rails管理员如何在下拉列表中显示100多个记录？

Question

Railsadmin在显示记录时最多只能记录100条记录。如果要自定义下拉列表，则要记录100条以上记录？

Answer 1

In config/initializers/rails_admin.rb needs to be changed to

 RailsAdmin.config do |config|
      config.model 'User'  do
        field :user_id, :enum do
        enum_method do :get_all_users 
       end
      end
    end
 end

In models/user.rb

def get_all_users
   User.all.map{|x|[x.id,x.name]}
end

You could use pluck instead of all.map
