price = models.CharField(max_length=255)
status = models.CharField(max_length=255,choices=PRICE_CHOICES)
My api views.py:
class BookViewSet(viewsets.ModelViewSet):
queryset = Book.objects.all()
serializer_class = BookSerializer
and serializer.py:
class BookSerializer(serializers.ModelSerializer):
class Meta:

U can use validation in many ways. Below is a sample
class BookSerializer(serializers.ModelSerializer):
class Meta:
model = Book
fields = ('id', 'price', 'status')
def create(self, validated_data):
# logic for creating object
# you can extract data from validated_data['name'] and then put your logic
return validated_data
def update(self, instance, validated_data):
# logic for updating object
return instance

You can throw an error when price exceeds a limit like this.
class BookSerializer(serializers.ModelSerializer):
class Meta:
model = Book
fields = ('id', 'price', 'status')
def validate_price(self, data):
if data > threshold:
raise ValidationError(message='...')
return data
If you want to alert a user and based on his response you want to make a decision then you need other logic. You need to introduce a new check variable/param in post input.
To set one book for user per day override validate method in serializer
class BookSerializer(serializers.ModelSerializer):
class Meta:
model = Book
fields = ('id', 'price', 'status')
def validate_price(self, data):
if data > threshold:
raise ValidationError(message='...')
return data
def validate(self, data):
# your logic, et user detail and date and check it with db. if found raise exception as shown above.

@a_k_v In your answer, if the price is higher than the threshold, the data will not be saved in DB. It needs to be clear what is the requirement here i.e. if we don't want to save higher price or do we want to save a higher price but with some kind of notification to the user. If the latter is the case, we can use signals with the post_save receiver.
