Rails - Jan 2008 - About query database and virtual attributes

Hi,

My model has a lot of virtual attributes. So when I use
find(:all, :condition=>blablabla),
can I use virtual attribute directly?

eg. in my model:
def mydatetime
   self.date+self.time
end
can i just use "mydatetime=xxx" to match the records in db?


of course, my model is far more complicated than this.

Any idea?

you would need to define mydatetime

def mydatetime=(datetime)
 date = datetime.some_modifier
 time = datetime.some_modifier
end

Unfortunately, it doesn''t solve the problem.

Error messege:
Mysql::Error: Unknown column ''who_chunk2'' in ''where
clause'': SELECT *
FROM `skus`   WHERE (who_chunk2=''Matt'')

My code is like:

def who_chunk2
    if !self.who_chunk.blank?
      if b=User.find_by_id(self.who_chunk)
        b.name
      end
    end
  end
  def who_chunk2=(st)
    if !st.blank?
      self.who_chunk=User.find_by_name(st).id
    end
  end
