Django FileField (or ImageField) open() method returns None for valid file?

Question

let me put it like this:

model.py:

class Task(models.Model):
    ...
    seq_file = models.FileField(upload_to=\'files/\', blank=True, null=True)
    ...         


        

Answer 1

Surprisingly but django.db.models.fields.files does not utilize file.storage.exists() method so I had to implement my own small function to have cross-storage compatible check for actual physical file existence:

# Check whether actual file of FileField exists (is not deleted / moved out).
def file_exists(obj):
    return obj.storage.exists(obj.name)
