Processing file uploads before object is saved

Question

I\'ve got a model like this:

class Talk(BaseModel):
  title        = models.CharField(max_length=200)
  mp3          = models.FileField(upload_to = u\'talks/         


        

Answer 1

a cleaner way to get the file before be saved is like this:

from django.core.exceptions import ValidationError

#this go in your class Model
def clean(self):
    try:
        f = self.mp3.file #the file in Memory
    except ValueError:
        raise ValidationError("A File is needed")
    f.__class__ #this prints 
    processfile(f)

and if we need a path, ther answer is in this other question
