How do you add roles rolify using cancan and devise?

I get that there are a lot of questions on this subject but none have really answered what i'm looking for.

I'm attempting to use rolify to define my roles in cancan, i was able to make an admin role via rails console and set the default role for new users.

My question is how do i set a batch of roles to different values and assign those roles to certain users?

If you have a good tutorial that explains this process that would help as well, screencasts preferred.

thanks!

How do you create a batch of roles?

You can do this in your db/seeds.rb file, which is executed each time you run rake db:seed

[:admin, :author, :contact, :user].each do |role|
  Role.find_or_create_by_name({ name: role }, without_protection: true)
end

Adding a role to someone is done like

@user.add_role :admin

You check whether a user has a certain role using

@user.has_role? :admin

And, as Steve already said, the https://github.com/EppO/rolify documentation should get you on the move!
