Ruby on Rails

For your second item:

I suggest that you download this:  https://github.com/dgleba/brail347a22

• cp  config/database-example.yml    config/database.yml   
  
• cp  config/application-example.yml config/application.yml
  
• cp  config/secrets-example.yml     config/secrets.yml    
  
• 
  
• Check db/../..seeds*.rb for username and password.
  
• bundle
• rails s

It was recently created by bashrail.

For your first item: 

If am answering your question, I would scaffold User2 to match the User resource.

Then, change the table name in user2.rb to the user table.

Like so,  

self.table_name = 'users'

This will allow you to edit the users table from user2/ url.

I will add this to bashrail when I get a chance.

I may not be answering your question on this one, but I just an admin tool to add a user since the administrator of the system must grant the proper role to the new user. 

So, if am using rails_admin with the project, add the user in that tool and assign the appropriate role_id.

The code can also be setup so a user can sign-up them selves and a default role is assigned.

You can also add a user with a tool such as phpmyadmin, pgadmin, sqlite-browser like http://sqlitebrowser.org/.

I see that in one spot you have Admin - capitalized. and in another it is not capitalized - admin.

I wonder if capitalization matters in your code.

Note that we can't see your code.  That makes it harder to help you when we can't see the code.

As the error says, self.role is nil
