How to translate django models or objects into any format. Let’s start.

First you have to install django rest framework to use the serializer as follows.

// Install globally
pip install djangorestframework
// Install using pipenv
pipenv install djangorestframework

Then add the django rest framework to the installed apps in settings.py.

INSTALLED_APPS = [
    ...
    'rest_framework',
]

First let’s make a simple model in models.py

from django.db import models
class Person(models.Model):
  name = models.CharField(max_length=100) 
  age = models.IntegerField()
  email = models.EmailField(max_length=254)
  def __str__(self): 
    return self.name

Then let’s create a serialiser which help us to convert data to a format which can be easily rendered into JSON, XML or other content types. Following code is placed in serializers.py .

from rest_framework import serializers
from .models import Person
class PersonSerializer(serializers.ModelSerializer):
  class Meta:
    model = Collection
    fields = ['id', 'name', 'age']

In serializer class you can get all the fields by altering fields = '__all__' or you can get all the fields excluding one fields changing fields to exclude = ['email'] .
