None of the answers solve the original problem. Restating the problem, how can I set the default value of a date field to todays date and still let the user override the default.

From the DJango docs:

DateField.auto_now
Automatically set the field to now every time the object is saved. Useful for "last-modified" timestamps. Note that the current date is always used; it's not just a default value that you can override.

DateField.auto_now_add
Automatically set the field to now when the object is first created. Useful for creation of timestamps. Note that the current date is always used; it's not just a default value that you can override.

The answer if this is not just a "when was this added/edited" field, is to use

default=datetime.date.today

note no parens. This sets the default to the function, not the value returned by the function when the model is evaluated.

django command extensions can help you with many things like:

  • CreationDateTimeField - DateTimeField that will automatically set it's date when the object is first saved to the database. Works in the same way as the deprecated auto_now_add keyword.
  • ModificationDateTimeField - DateTimeField that will automatically set it's date when an object is saved to the database. Works in the same way as the deprecated auto_now keyword.

Use auto_now_add instead, as auto_now would change the vote date any time the object is modified.

This resolve my problem:

vote_date = models.DateField(_('vote date'), null=False, blank=False, auto_now=True)
