NoMethodError: undefined method `admin=' for #<User:0x00000002ceae30> - mysql

Currently I'm using the latest version of rails_admin and devise gem and have to two signed_in users
Running via Spring preloader in process 4912
Loading development environment (Rails 5.0.0.1)
2.3.1 :001 > u = User.first
User Load (0.4ms) SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT ? [["LIMIT", 1]]
=> #<User id: 1, email: "dhami.khawas#gmail.com", created_at: "2016-08-15 10:26:16", updated_at: "2016-08-16 12:48:11">
2.3.1 :002 > u = User.last
User Load (0.7ms) SELECT "users".* FROM "users" ORDER BY "users"."id" DESC LIMIT ? [["LIMIT", 1]]
=> #<User id: 2, email: "linux#gmail.com", created_at: "2016-08-16 10:03:10", updated_at: "2016-08-19 08:18:23">
2.3.1 :003
How do I make any one of them as Admin User? I tried running below operation but ended up in errors.

This migration which creates the users table 20200103171631_devise_create_users.rb comes before the one that is currently failing 20200108204517_add_first_and_last_name_to_users.rb. So of course the error makes sense -- the migrate to create the users table did not run first. However, my question is, why is 0200108204517_add_first_and_last_name_to_users.rb running before the migration which creates the users 20200103171631_devise_create_users.rb ? I do believe the date on the file here 20200103171631_devise_create_users.rb has an earlier date and should be running before 0200108204517_add_first_and_last_name_to_users.rb.
my rails app is using:
gem 'rails', '~> 6.0.1'
gem 'mysql2', '>= 0.4.4'
gem 'devise', '~> 4.7.1'
Did you check my_database.schema_migrations table? You may find that Rails has already marked this migration as executed.
See https://edgeguides.rubyonrails.org/active_record_migrations.html#old-migrations
The users table may not exist because it's possible it was deleted manually.

(See full trace by running task with --trace)
See at config/application.rb the config.time_zone section.
You could run rake -D time to show all timezone available.
You may have a migration pending. Try running:
rails db:migrate
Add a time_zone to your config file,
config.time_zone = 'Australia/Melbourne'
You can change it to be whatever timezone your application will be in, you can also do
config.time_zone = 'UTC'
Experienced the same problem, showed that my teammate had changed the config/master.key code. Once updated, things went to normal again.

And my database.yml file is below
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: colloquy_development
pool: 5
username: root
password:
socket: /Applications/MAMP/tmp/mysql/mysql.sock

Ruby on rails app won't run because of error with mysql

I created a new Rails application using the command from the Ubuntu terminal:
rails new testing -d mysql
I then added the root password in the database.yml file
when I run the command rails server to run the application on the server the following occurs:
=> Booting WEBrick
=> Rails 3.2.13 application starting in`enter code here` development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting

Can anyone help me with the problem?
You have to create the Database first.
