authentication - Best way to implement ban system for rails app -

-

i'm using devise cancan authentication in rails app , i'd able block accounts , prevent users registering blocked email , phone. i'm not sure best way this.

i have roles: admin, moderator, , user admin: must have ability ban/block moderators, , users moderator: must have ability ban/block users

my first thought add new 'blocked' role, think there better way.

i go simplest way : boolean "blocked" on user table. define :

class user    def block(other_user)     if(can_block? other_user)       other_user.block = true       other_user.save!     end   end    def can_block?(other_user)     # logic using roles.   end end

straightforward, way.
