[pyar] Validator Django Rest

[Antonio Storni]

Buenas,

Si lo queres validar es el campo "resume", deberías usar el
FileExtensionValidator directamente en el modelo.

    resume =
models.FileField(validators=[FileExtensionValidator(allowed_extensions=['pdf'])],
....

Mirá https://docs.djangoproject.com/en/1.11/ref/validators/

Saludos
Antonio
