This project is an attempt to provide new DRF Serializer base classes that work for the majority of use cases.
$ pip install -e .
$ pip install "file://$(pwd)#egg=drf-nested-serializer[dev]"
$ python setup.py testFor example, given these simple related models, and a single serializer:
from django.db import models
from nested_serializers import NestedSerializer
class Tag(models.Model):
name = models.CharField(max_length=255)
class FeatureType(models.Model):
name = models.CharField(max_length=255)
class Article(models.Model):
title = models.CharField(max_length=255)
tags = models.ManyToManyField(Tag)
feature_type = models.ForeignKey(FeatureType)
class ArticleSerializer(NestedSerializer):
class Meta:
model = ArticleWe can add add existing feature types to new articles:
serializer = ArticleSerializer(data={
'title': 'testing',
'feature_type': {
'id': 1
}
})
assert serializer.is_valid()
instance = serializer.save()However, you cannot descend into nested models and lists to create new instances. This is a controversial
point in REST, and it is the opinion of the team that it's ideal to independently POST nested objects
before they are PUT into another object.
