Django Multiple File Field

For guys from 2017 and later, there is a special section in Django docs. My personal solution was this (successfully works in admin):

class ProductImageForm(forms.ModelForm):    # this will return only first saved image on save()    image = forms.ImageField(widget=forms.FileInput(attrs={'multiple': True}), required=True)    class Meta:        model = ProductImage        fields = ['image', 'position']    def save(self, *args, **kwargs):        # multiple file upload        # NB: does not respect 'commit' kwarg        file_list = natsorted(self.files.getlist('{}-image'.format(self.prefix)), key=lambda file: file.name)        self.instance.image = file_list[0]        for file in file_list[1:]:            ProductImage.objects.create(                product=self.cleaned_data['product'],                image=file,                position=self.cleaned_data['position'],            )        return super().save(*args, **kwargs)

No there isn't a single field that knows how to store multiple images shipped with Django. Uploaded files are stored as file path strings in the model, so it's essentially a CharField that knows how to be converted to python.

The typical multiple image relationship is built as a separate Image model with an FK pointing to its relevant model, such as ProductImage -> Product.

This setup makes it very easy to add into the django admin as an Inline.

An M2M field would make sense if you it's truly a many to many relationship where say GalleryImages are referenced from 1 or more Gallery objects.

I had to change from having a single file to multiple files in an existing system and after a bit of research ended up using this: https://github.com/bartTC/django-attachments

It should be easy to subclass the model if you want custom methods.
