hello,
class MyFile(models.Model) :
content = models.FileField(upload_to = '.')
type = models.IntegerField(editable = False)
when a file is submitted through a form post i need to check whether
the file format is valid and set the "type" field to indicate the
format.
i can see two ways to do it. one is to add a validator to the
"content" field, that would also set the "type" field. the other is to
overload "save" method and set "type" there. which one is right? if it
is the latter, should "save" throw "ValidationError" just like a
validator if the file format is invalid?
thanks
konstantin
