Django ModelForm and datetimefield : no widget

Question

I try to display a modelform containing a datetime field

But when I try to display this field, anything wants to appear.

In the model form, when I print self.fields :

{'status': <django.forms.fields.TypedChoiceField object at 0x1340e10>, 'reserved': <django.forms.fields.BooleanField object at 0x1340cd0>, 'date_publication': None, 'date_creation': None}

Here's the model :

class News(MultiLangModel):
 date_creation = models.DateTimeField(auto_now_add=True, verbose_name=_("Date"))
 date_publication = models.DateTimeField(auto_now_add=True, verbose_name=_("Publication date"))
 status        = models.CharField(max_length=10,         verbose_name=_("Status"), choices=POST_STATUS_CHOICES)
 reserved   = models.BooleanField(default=False, verbose_name=_(u"News reserved to supporters"))

What can be the reason of this bug ?

Answer 1

You have set the auto_now_add attribute to True for date_publication. This implies that the value of this field will be set automatically and not from user input. To verify this remove the auto_now_add attribute and try again.

From the docs for 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.
