Problem converting from standard django form select to select2 - django

Question

I am trying to convert django form from using standard select to select2. I have followed instruction and installed django-select-forms, added select2 to INSTALLED_APPS, and include select2 links and scripts in the header block
Here is my original code
Model.py
class Photographer(models.Model):
author_id = models.CharField(max_length=50, primary_key=True)
displayname = models.CharField(max_length=50)
forms.py
class UploadFileForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(UploadFileForm, self).__init__(*args, **kwargs)
self.fields['author'].required = True
self.fields['author'].queryset =
Photographer.objects.all().order_by('displayname')
Is ther anyway I can do this without changing my model?

Normally you only will need to specify the widget you use:
from django_select2.forms import Select2Widget
class UploadFileForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(UploadFileForm, self).__init__(*args, **kwargs)
self.fields['author'].required = True
self.fields['author'].queryset = Photographer.objects.order_by('displayname')
class Meta:
widgets = {'author': Select2Widget }
That being said, since you already are specifying some data in the __init__, it might be more elgant to define this as a class attribute instead:
from django_select2.forms import Select2Widget
class UploadFileForm(forms.ModelForm):
author = ModelChoiceField(
queryset=Photographer.objects.order_by('displayname'),
required=True,
widget=Select2Widget
)
