Rails - Nov 2005 - active record accessor behavior

''name'' is a column in the database. I want the following
accessor to be run
whenever a record is found. In the stock scaffolding it works for the list
view but not for the edit view. What am I doing wrong?

def name
user = User.find(self.user_id)
if read_attribute(''name'')
=~/(__)(#{user.username})(__)(.*?)(__)/
read_attribute(''name'').gsub!(/(__)(#{user.username})(__)(.*?)(__)/,''\4'')
else
read_attribute(''name'')
end
end

You shouldn''t be finding a User if you already have a User object,
though I''m not sure why what you did failed.  Anyway, try:

def name
    read_attribute(''name'')
=~/(?:__)(?:#{username})(?:__)(.*?)(?:__)/
? $1 : read_attribute(''name'')
  end

Actually User is another model that this model belongs to. I would prefer to
use @session["username"], but since you can''t access that
from a model as
far as I can tell, I have to do User.find(thismodel.user_id).

But I found a better way to do this anyways. The not very well documented
after_find callback seems to be a better fit.
