django serializer code example

Example 1: serialization in django

serialization in django

from rest_framework import serializers
from .models import Product

class ProductSerializers(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = '__all__'
        
# Serializers allow complex data such as querysets and model instances to be converted to native Python datatypes that can then be easily rendered into JSON, XML or other content types. 
# Serializers also provide deserialization, allowing parsed data to be converted back into complex types, after first validating the incoming data.

Example 2: drf serializer

serializer = CommentSerializer(data={'email': 'foobar', 'content': 'baz'})
serializer.is_valid()
# False
serializer.errors
# {'email': ['Enter a valid e-mail address.'], 'created': ['This field is required.']}

Example 3: User serializer in django rest framework

class Event(models.Model):
    user = models.ForeignKey(to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    date = models.DateTimeField(default=timezone.now)
    place = models.CharField(max_length=255)
