When trying to use the modelformset_factory I get the following error.

Environment:

Here's my model

class Services(models.Model):
    departure_id = models.ForeignKey(Departures)
    service_name = models.TextField()
    service_code = models.CharField(max_length=20)
    service_date = models.DateField()
    service_type = models.CharField(max_length=40)
    paid_by = models.CharField(max_length=40)
    cost = models.DecimalField(max_digits=10, decimal_places=2)
    cost_currency = models.CharField(max_length=6)
    deleted = models.BooleanField()
    deleted_by = models.IntegerField()
    deleted_reason = models.TextField()
    validated = models.BooleanField()
    validated_by = models.IntegerField()
    updated = models.DateField(auto_now=True)

Here's my form

class ServiceForm(forms.ModelForm):
    class Meta:
        model = Services
        exclude = ('departure_id',)

Here's my initialization

ServiceFormSet = modelformset_factory(ServiceForm)

You're passing the Form as the model parameter.

signature is: def modelform_factory(model, form=ModelForm, fields=None, exclude=None, formfield_callback=None):

[anonymous]

ehh wrong copy paste:

def modelformset_factory(model, form=ModelForm, formfield_callback=None,

formset=BaseModelFormSet,
extra=1, can_delete=False, can_order=False,
max_num=None, fields=None, exclude=None):
