How can I filter the imagefield by filename in django

Question

I add a ImageField in my model like

class UserImage(models.Model):
    photo = models.ImageField(upload_to='target_path')
    ....

after I save an image, let's say 'a.jpg', then I want user the filename 'a.jpg' to filter the model, what should I write like:

UserImage.objects.filter(photo.filename='a.jpg')
....

Answer 1

Your suggestion would give you an error. Try this instead:

UserImage.objects.filter(photo='a.jpg')

Edit: Django prepends the upload_path to the file name. The query should then do something similar, for example:

UserImage.objects.filter(photo='images/users/photos/a.jpg')

Answer 2

The above answer will correctly work moreover you can use icontains too as i am using

comment_qs = Upload.objects.filter(title__icontains=str(file_name)).filter(content_type__model='Task')
