Thanks Zak, but it''s not what i need. I don''t want it to be UPDATED(ie Edit) And i need this attribute, when object is being CREATED(ie New). So it could look like this(the code isnt'' valid): .... attr_accessible :name, :description attr_accessible :email if new_record? .... Any ideas? Thanks!

I''d say you should do something like... attr_accessor :address attr_protected :email def before_create self.email = address end and use User#address in the form.

I''m not overly optimistic about our chances of getting it added, though.. Another option for emulating read only attributes could be a before_save callback that; locks the row (select for update), then load the model into some variable and then copy the field in question into self. I''m not sure Russel''s approach will work; say you load the model, the row/column is changed by some other process, and then you save your old model again overwriting the new value. I''d just go with attr_protected and set that field individually on creation, if this is all you need.

Well, for now Russel''s approach is just fine. The issue with other processes modifying attribute directly can be avoided by putting attr_reader for :email, so it'' won''t be changed from outside. Right? Thanks!
