Django admin file upload with current model id

Question

I\'m trying to create a simple photo gallery with the default Django admin. I\'d like to save a sample photo for each gallery, but I don\'t want to keep the filname. Instead

Answer 1

For Django 2.2, follow the below code.

def save(self, *args, **kwargs):
    if self.pk is None:
        saved_image = self.image
        self.image = None
        super(Gallery, self).save(*args, **kwargs)
        self.image = saved_image
        if 'force_insert' in kwargs:
            kwargs.pop('force_insert')

    super(Gallery, self).save(*args, **kwargs)

Add the above code snippet to your 'class Gallery'.

P.S.: This will work for DRF as well when you save via views.py. Note that second if (condition) is required for DRF.
