You need to have any other unique attribute on the User model, e.g. some random GUID value, once you have it, just use it instead of the ID:

<a href="/home/layout02_03/<%= @interest.obscure_uniq_identifier %>">

Or define it to be the default URL representation for the User:

class User

def to_param
  obscure_uniq_identifier
end

You can generate one using:

before_create :generate_guid
def generate_guid
  self.obscure_uniq_identifier = SecureRandom.hex
end

For anyone who is having the same issue, I would also suggest you to use a gem like Visibilize which offers more options on creating exposable friendly ID's.

Just install the gem and call visibilize inside your model.
