Normalize Your Django REST Serializers

When dealing with models with nested relationships, it may initially make sense to serialize them in a nested format. However, you may soon discover that this has a couple of potential issues.

  2. Since those objects are nested, you don’t have them all in one place for easy referencing or updating. Working around this requires tedious iteration and transformation.

These issues are especially pronounced in Javascript applications that use state methodologies or technologies like Redux. Redux applications work much better when your data is normalized. Normalization facilitates cleaner code, makes updating state simpler, and ensures that the fewest possible UI components are forced to re-render due to such updates.
