Django Model Validators

Django model validators adds a few common validators in addition to Django's built-in validators.

Installation

Run pip install django-model-validators

Validators

FileTypeValidator

Ensures an upload file name ends in an extension.

from django.db import models
from model_validators.validators import FileTypeValidator

class MyModel(models.Model):
    even_field = models.IntegerField(validators=[FileTypeValidator('zip')])

It can also be passed a list of extensions:

from django.db import models

class MyModel(models.Model):
    even_field = models.IntegerField(validators=[FileTypeValidator(['zip', 'txt', 'pdf'])])

NumericRangeValidator

Ensure the field value falls within the specified range.

from django.db import models
from model_validators.validators import NumericRangeValidator

class MyModel(models.Model):
    rating = models.PositiveIntegerField(validators=[NumericRangeValidator(1, 10)])
