Problems with the Model.DateField format

Question

I have a model that has a date field

date_of_birth = models.DateField(blank=True, null=True, verbose_name="DOB")

I would like to format it to save the dates in a format dd/MM/yyyy, but everything I tried fails.

I think that should be by default YYYY-MM-ddbecause it saves my database. Trying to send dates in a different format gives an error:

[u"'17/01/1970' value has an invalid date format. It must be in YYYY-MM-DD format."]

I tried using Date Widgets , but I have several issues related to its compatibility with my machines.

"[...] you need full control over the field, you can do this by declaratively specifying the fields, as in the usual form." Here is my example:

class UserCreationForm(BaseUserCreationForm):
    birth_date = forms.DateField(input_formats=['%d/%m/%Y'])

    class Meta(BaseUserCreationForm.Meta):
        model = User
        fields = ("username", "first_name", "last_name", "email", "birth_date")
