Django Rest Framework Temperature Data Querying

[Burak Özdemir]

My sensor measures the temperature value every 5 seconds and records it to the database. I want to see the highest and lowest temperature of every recorded day via API. It should be like that(for instance, values are not correct): 

The modal:

class SensorModel(models.Model):
    measurementTime = models.DateTimeField()
    ldr = models.IntegerField()
    temperature = models.IntegerField()
    humidity = models.IntegerField()

class Meta:
    ordering = ['measurementTime']

def __unicode__(self):
    return str(self.id)

Database:

Current API: 

Thanks in advance.

List_route or detail route decorators sounds like what you are looking for http://www.django-rest-framework.org/api-guide/viewsets/#marking-extra-actions-for-routing

Actually, I  think he wants a custom serializer that has one of 2 get arguments(start and end date) and then generates the desired json with fields using the django aggregate methods

There are lots of temperature data for one day. For instance, there are nearly 5000 records for 03 January. I want to get highest and lowest of these records for one specific day.

On a custom serializer field, (eg SerializerMethodField) use the django aggregate functions for max and min https://docs.djangoproject.com/en/1.10/topics/db/aggregation/
