I ran into the same problem a few weeks ago. I solved it by manually
entering a blank field into my filter choices. Yours could look like
this:
TICKET_STATUS_CHOICES = (
('new', 'New'),
('accepted', 'Accepted'),
('assigned', 'Assigned'),
('reopened', 'Reopened'),
('closed', 'Closed'),
)
class Ticket(models.Model):
assigned_to = models.ForeignKey(User, null=True, blank=True)
status = models.CharField(max_length=20,
choices=TICKET_STATUS_CHOICES, default='new')
import django_filters
FILTER_STATUS_CHOICES = (
('', '---------'), #using single quotes
('new', 'New'),
('accepted', 'Accepted'),
('assigned', 'Assigned'),
('reopened', 'Reopened'),
('closed', 'Closed'),
)
class TicketFilter(django_filters.FilterSet):
status = django_filters.ChoiceFilter
(choices=FILTER_STATUS_CHOICES, label='Status')
class Meta:
model = Ticket
fields = ['assigned_to', 'status']
That should give you what you're looking for. I'm using a LinkWidget
for mine, and it automatically displays an "All" option for the blank
value.
