Hi,
I’m a rails newbie trying to develop a blog application with rails. I’ve
some troubles to find the best way of automaticly set a field value on
update and creation of a blog item.
In fact my problem is very simple. I’ve a blog table with two column
named create_date an mod_date. And I’d like :
1 - that create_date is set on creation and is never modified after that
2 - mod_date is set on update
Pre-Thanks for help.
Antonin.

Thank you for your quick answer.
I understand that all this is about naming conventions ??
_on make the column to be updated when modification is made
_at make the column to be set a creation time
Am i right ?
Also, what if i want some field to be set by some code but not by the
user.
I have a field ‘user_id’, not yet a table representing the user. I’ve
seen this is automatically not-displayed in the scaffold. But, how can I
set it with some piece of code when the record is created ?

I’m not ! i’ve just try this, an it doesn’t do what i want. 
modification an creation date can still be modified by the user.
