[Nitro] og, select

[jfwittmann]

hello,

I want extend an og mixin.
this is what i have and found out about og. I get my entity objects.
But how can I get the "level" value in my entity objects ? this 
attribute should not  exist in the storage table. it's like a virtual 
attribute

base.module_eval <<-EOE, __FILE__, __LINE__
....
            class << self
                def all(options = {})
                    table = Og.manager.store.table(#{base})
                    sql = %{
                        SELECT o1.*, COUNT(*) AS level
                        FROM
                        \#{table} AS o1,
                        GROUP BY o1.#{left};
                    }
                    return self.select(sql)
              end
            end


thanks,

Felix
