Hi
I remember once I read about to get only updated fields from an
update_attributes method. Means say I have a model user with
name,age,sex etc And when the user updates the information I have to
first check whether he actually updated anything(There is a chance that
update button from view simply being clicked) and if only any updates
happened I have to get that updated fields and send a mail stating that
these fields are updated. How can I do this. Suppose in the above
example if only name updated
Thanks
Tom
Tom, you should be able to do the following to get the attributes that have
been changed:
model_instance.changed
Next, you'll need to store this information prior to saving the changes
to the database. Otherwise, the above method will return an empty array.
Good luck,
