I’m pretty sure that there’s a better way to do this:
@roles = Role.find(:all)
@selected_role = Role.find(@user.role_id)
Can someone help me?

Why not just (assuming user is associated to role):
@selected_role = @user.role
Since this is the second question like this, with essentially the same
answer I’m going to flesh out the answer a little further.
If you have a schema like this:
roles
t.integer :id
t.string :name
users
t.integer :id
t.string :first_name
t.string :last_name
t.integer :role_id
And models like this:
class Role < ActiveRecord::Base
has_many :users
end
class User < ActiveRecord::Base
belongs_to :role
end
Then you can do stuff like this:
role = Role.find_by_name(“Administrators”) # Get the role named
“Administrators”
users = role.users # Get all the users in the role
user = role.users.find(:first, :order => :last_name) # Find the first
user in the role ordered by last name
user.role.name # Get the name of the role of the user
