drf-prettify-json-serializer

You got ugly json, we got a serializer that can massage that data into something useful

Sometimes you get "json", that you have NO control over and the json is ugly. I mean really Ugly and Inconsistant.

So, being the control-freak that you are you decide to bring order to the chaos, but for some reason DRF does not allow data massaging. Which is a pity as its a a damned fine presenter pattern implementation but lacks this tiny bit of functionality.

so if source is defined it will read that from the provided json data.

NB this field class is for serialization of json data only.

Installation

pip install drf-prettify-json-serializer-field

About

For example:

#
# argh! my eyes... dear lord! are we enterprise or what?
#
{
    "customerID": "123",                     # lowercase uppercase
    "CustomerUID": "abc456",                 # CamelUpper
    "CustomerEmail": "bob@example.com",      # CamelCase
    "KundenKarteNr": "Ad0ek344",             # This is not a number and its not english
    "CardType": 1,                           # this one is ok, but CamelCase
    "Filial": "3",                           # not english and ugly
}

is brought under control like so:

import drf_prettify_json_serializer_field.fields  as json_source_fields


class CustomerSerializer(serializers.Serializer):
    customer_id = json_source_fields.IntegerField(source='customerID')
    customer_uid = json_source_fields.CharField(source='CustomerUID', allow_null=True)
    email = json_source_fields.EmailField(source='CustomerEmail', allow_null=True)
    card = json_source_fields.CharField(source='KundenKarteNr')
    card_type = json_source_fields.IntegerField(source='CardType')
    store = json_source_fields.IntegerField(source='Sill.Seperator.Deepnested.Filial')

#
# ahh better
#
{
    "customer_id": 123,
    "customer_uid": "abc456",
    "email": "bob@example.com",
    "card": "Ad0ek344",
    "card_type": 1,
    "store": 3,
}

And to add fields you simply

class ExistingField(PrettifyDataFromJsonField, serializers.ExistingField):
    pass

TODO

1. tests
2. deep nested key references (dot seperated)
