How to display category name on article model? - django

Question

I want to render category field on an article in terms of its name(choice). Currently, it is rendered as an Id. Also, I want to be able to update the article model by entering category name(choice) instead of its Id(I am currently doing this). How can I go about implementing this?
This is what I have so far.
Models
class Category(models.Model):
"""
Model for Category
"""
CATEGORY_CHOICES = (
('Sports', 'Sports'),
('Music', 'Music'),
('Drama', 'Drama'),
('Money', 'Money'),
('Movies', 'Movies'),
('Cars', 'Cars'),
('General', 'General'),
)
name = models.CharField(max_length=30, choices=CATEGORY_CHOICES, default='General',null=False, blank=True)
def __str__(self):
return self.name
class Article(models.Model):
"""
Model for an Article
"""
title = models.CharField(max_length=255, null=False, blank=False)
description = models.TextField(null=False, blank=False)
body = models.TextField(null=False, blank=False,)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
Serializers
class ArticleSerializer(serializers.ModelSerializer):
"""
Serializer for Article.
"""
class Meta:
model = Article
fields = ('title','description','body',''category')
class CategorySerializer(serializers.ModelSerializer):
"""
Serializer for Category.
"""
class Meta:
model = Category
fields = ('name',)
Current output
Expected output

Answer 1

You can change your ArticleSerializer to have the category field as a CharField with a source attribute:
class ArticleSerializer(serializers.ModelSerializer):
category = serializers.CharField(source='category.name')
class Meta:
model = Article
fields = ('title','description','body',''category')
To be able to update the Article's category via the name, you have to make sure that name is a unique field for Category. If yes, then you can use a SlugRelatedField.
category = serializers.SlugRelatedField(slug_field='name')
