How can I validate file uploads in Django?

You can validate file uploads in Django by using the built-in validators in your model or form. What type of files are you looking to validate?

I want to validate image files, like JPEG and PNG.

You can use the FileExtensionValidator to restrict file types. For images, you can also check the file size and dimensions.

Can you show me an example of how to implement that?

Sure! In your model, you can do something like this:

from django.core.validators import FileExtensionValidator
from django.db import models

class MyModel(models.Model):
    image = models.ImageField(validators=[FileExtensionValidator(allowed_extensions=['jpg', 'png'])])

This will ensure only JPEG and PNG files are uploaded.

What about limiting the file size?

You can override the save method in your model to check the file size before saving. Would you like a code example for that?
