I'm having a problem with displaying the data during serialization.
This is my model:
from django.db import models
class Paradigmn(models.Model):
name = models.CharField(max_length=50)
def __str__(self):
return self.name
class Language(models.Model):
name = models.CharField(max_length=50)
paradigm = models.ForeignKey(Paradigmn, on_delete=models.CASCADE)
def __str__(self):
return self.name
class Programmer(models.Model):
name = models.CharField(max_length=50)
languages = models.ManyToManyField(Language, related_name='languages')
def __str__(self):
return self.name
And this is my serializer:
from languages.models import Language, Paradigmn, Programmer
class LanguageSerializer(serializers.ModelSerializer):
paradigms = serializers.ReadOnlyField(source='paradigm.name')
class Meta:
model = Language
fields = ('id', 'name', 'paradigms')
class ParadigmnSerializer(serializers.ModelSerializer):
class Meta:
model = Paradigmn
fields = ('id', 'name',)
class ProgrammerSerializer(serializers.ModelSerializer):
languages = LanguageSerializer(many=True, read_only=True)
class Meta:
model = Programmer
fields = ('id', 'name', 'languages')
And this is the result:
[
"id": 1,
"name": "Ryan",
"languages": [
"id": 1,
"name": "Java",
"paradigms": "Object-Oriented"
]
,
"id": 2,
"name": "Jean",
"languages": [
"id": 3,
"name": "Python",
"paradigms": "Object-Oriented"
]
,
"id": 3,
"name": "Michael",
"languages": [
"id": 2,
"name": "Elixir",
"paradigms": "Functional"
]
I just want to show on the languages array, the name of the language instead of the all the details of the language array. What is the best solution for this?

No need to have ` languages = LanguageSerializer(many=True, read_only=True)` in LanguageSerializer` than. As self.name properly define in Language Model.
