Here is my adminuser model

class AdminUser < ApplicationRecord role_based_authorizable devise :database_authenticatable, :recoverable, :rememberable, :trackable attr_accessor :login has_many :classrooms protected

I am trying to use Active_admin to make an admin app that will allow my non-profit to take attendance of students in our program among other things such as sign permissions, calendar etc. I was trying to make a page for the classroom model called 'Attendance' when the app broke with the above error in the title"Sprockets::FileNotFound - couldn't find file 'active_admin/base' with type 'text/css'". I tried to remove gems, re-install gems and restarted my server many times. I have searched on here and online to no avail, any help I would greatly appreciate.

my application.js

I am using activeadmin_addons plugin in rails active admin for populating select dropdown using ajax, for that i used Select2 (search_select given by activeadmin_addons). The add on is working fine but i am unable to set default value for select dropdown when the active admin form loads in case of edit form scenario.
