Hola Sako!
Remember that the philosophy of EOF is to put all the logic in your
EO's ---not in the database or else-were. Therefore the mechanism
proposed to accomplish this is to put your default values on code in
your EORecords.
From the docs:
public void awakeFromInsertion(EOEditingContext ec)
Overridden by subclasses to perform additional initialization on the
receiver upon its being inserted into ec. This is commonly used to
assign default values or record the time of insertion.
EOCustomObject's implementation merely sends an
awakeObjectFromInsertion to the receiver's EOClassDescription.
Subclasses should invoke super's implementation before performing
their own initialization.
Suerte!

Hello,
i have in the databse some default values for some attributes.
Some of these attributes do not accept null.
My problem is, EOF does not know the attributes have default value. if
user
does not inserts any value an exception is thorwn.
Any can give me a hint to solve this?
Thank you,
Sako.
