Re: FileField Model Required

The solution I have found is overriding the save function from the model class:

class FileUpload(models.Model):

owner = models.CharField(max_length=200,blank=False, null=False)

record = models.FileField(upload_to=path_and_rename)

def save(self, force_insert=False, force_update=False, *args, **kwargs):

    if not bool(self.record):

         raise ValidationError("Record is required")

         super(FileUpload, self).save(force_insert, force_update, *args, **kwargs)

Is there another way to do it?

Best regards,

Cyril

Hi,

Is it possible to mark a FileField in my model as required

My model looks like :

class FileUpload(models.Model):

owner = models.CharField(max_length=200,blank=False, null=False)

record = models.FileField(upload_to=path_and_rename,blank=False, null=False)

1st statement :

According to what i have read the blank and null parameter are not necessary

and only the parameter "upload_to" and "storage" are availables

2nd statement : 

Secondly, it seems that the field validation are done at the form level or serializer level.

I would like to know if these 2 statements are true?

when I use python manage.py shell and make a test of creating a FileUpload object and save it, i dont get any error saying the that filefield is required :

## steps :

test = FileUpload(owner="test")

test.save()

## expected :

Error : filefield "record" is required!

## actual behavior :

save the object without error

Is it possible to put the filefield as required at the model level?

or

Do i have to make the validation of the field before/at an upper level?

Thank you

Cyril
