Description
I am attempting to add an ArrayField of IntegerFields to my model with a default value of list. I would expect the field to be populated with an empty list when the object is created, but when I call full_clean a ValidationError is thrown.
`
my_array_field = ArrayField(base_field=models.IntegerField(), default=list)
...
obj = MyObject.objects.create()
obj.full_clean()
`
The error I'm seeing is that the field cannot be empty:
`
django.core.exceptions.ValidationError: {'my_array_field': Ce champ ne peut pas être vide.}
`
I saw this ticket : https://forum.djangoproject.com/t/fields-with-db-default-fail-on-full-clean/28153 so I attempted to use db_default=list()
and db_default=[]
alone and in conjunction with default
but none of it seems to work.
Is this a bug? Am I just defining the default wrong?
I can't see an example of defining the default in the docs, although it does mention it : https://docs.djangoproject.com/en/5.0/ref/contrib/postgres/fields/#django.contrib.postgres.fields.ArrayField.base_field
I'm on Django 5.0.3

The docs on the additional fields from django.contrib.postgres.fields
I think (rightly) assume more basic knowledge about null
, blank
, and default
, so I'm reluctant to suggest we re-document those basics on ArrayField
.
I fixed the issue by adding blank=True to the ArrayField definition.
Glad you found the answer.
I fixed the issue by adding
blank=True
to theArrayField
definition. I see now in the docshttps://docs.djangoproject.com/en/5.0/ref/models/fields/#null
Maybe the docs for
blank
and the mention of settingdefault=list
in theArrayField
docs could be updated?
