serialization

https://www.django-rest-framework.org/api-guide/serializers/#serializers

json response를 받고 그 데이터를 바로 serialize해서 model instance를 생성가능하다.

== ORM

class UserProfile(models.Model):

id = models.AutoField(primary_key=True)

full_name = models.CharField(max_length=500)

last_login_at = models.DateTimeField(blank=True, null=True)

time_zone = models.CharField(max_length=100, blank=True, null=True)

class Meta:

managed = False

db_table = 'user_profile'

class UserAccount(models.Model):

user_profile = models.OneToOneField(UserProfile, on_delete=models.CASCADE, primary_key=True)

email = models.CharField(max_length=255)

password = models.CharField(max_length=255, blank=True, null=True)

resetpw_auth_number = models.IntegerField(blank=True, null=True)

created_at = models.DateTimeField(blank=True, null=True)

class Meta:

managed = False

db_table = 'user_account'

class UserProfileSerializer(serializers.ModelSerializer):

class Meta:

model = UserProfile

fields = '__all__'

class UserAccountSerializer(serializers.ModelSerializer):

user_profile = UserProfileSerializer()

class Meta:

model = UserAccount

fields = '__all__'

def create(self, validated_data):

user_profile_data = validated_data.pop('user_profile')

profile = UserProfile.objects.create(**user_profile_data)

account = UserAccount.objects.create(user_profile=profile, **validated_data)

return account

serializers = UserAccountSerializer(data=data)

if serializers.is_valid():

print(repr(serializers))

serializers.create(serializers.validated_data)

else:

return HttpResponse(json.dumps(serializers.errors, ensure_ascii=True), status=404, content_type="application/json")

return JsonResponse(data, status=201)
