Django Rest Framework: Converting a model object number into its corresponding string

I've an application which contains two different models, related by a Many-to-Many relationship as follows:

from django.db import models


class Genres(models.Model):
    genre = models.CharField(max_length = 128, unique = True)

class Movies(models.Model):
    popularity = models.FloatField()
    director = models.CharField(max_length = 128)
    genre = models.ManyToManyField(Genres, related_name = 'movies')
    imdb_score = models.FloatField()
    movie_name = models.CharField(max_length = 500)

serializers.py

from shoppy.models import Movies, Genres
from rest_framework import serializers


class GenresSerializer(serializers.ModelSerializer):

    class Meta:
        model = Genres
        fields = ('genre',)

class MoviesSerializer(serializers.ModelSerializer):
    #genre = serializers.CharField(max_length = 128, choices = Movies.GENRE_CHOICES)

    class Meta:
        model = Movies
        fields = ('popularity', 'director', 'imdb_score', 'genre',
                        'movie_name')

This is how my API endpoint form at http://localhost:8000/movies/ looks like:

enter image description here

Now, instead of different genres appearing as instances of Genres object numbers, how can I make them appear as the actual string corresponding to each object number? For example, Genres object-1 corresponds to Comedy, and that is what I want to be displayed in the API endpoint form to make the genre choices more human-readable.

What's the way to do something like that?

You need to implement a __str__ method in your Genres model.

class Genres(models.Model):
    genre = models.CharField(max_length = 128, unique = True)

    def __str__(self):
        return '%s'%self.genre
