Your problem is here:

> @user.skill_ids
> NoMethodError: undefined method `skill_ids' for
> #<ActiveRecord::Relation:0x00000005515b58>
> @user.role_ids
> NoMethodError: undefined method `skill_ids' for
> #<ActiveRecord::Relation:0x00000005515b58>

Try @user.skills.all and @user.roles.all.

Of you really DO want just the ids (seriously ask yourself why), then
@user.skills.all.collect(&:id) and @user.roles.all.collect(&:id)

It is no good just saying 'not working'. Post exactly what you have
tried and exactly what the result is.

By the way please don't top post, it makes it difficult to follow the
thread. Insert your replies inline at appropriate points in the
previous message. Thanks.

Why do you have these att_accessible things? If these are the columns from the database table users, then ActiveRecord will already take care of those. I think you should take out the entire attr_accessible line and try again.  (Well, depending on how they are used, you might need to retain a `attr_accessor ... Ah, you have attr_accessible (an ActiveRecord thing) not attr_accessor (a Ruby thing).) OK, so I still wonder if having :skill_ids in that list is wrong since it is not a column, but a method added by ActiveRecord. (and same for :role_ids)

    def role?(role)
    return !!self.roles.find_by_name(role.to_s.camelize)
  end
    def skill?(skill)
    return !!self.skills.find_by_name(skill.to_s.camelize)
  end

Unless you actually depend on true/false rather than just truthiness, you don't need the !! (or the return)

  def role?(a_role)

    self.roles.find_by_name(a_role.to_s.camelize)
