Compare Date from a database to current date and alert user if it's late

Question

I have a database set up, I am running Django for the backend and React.js for the front. This is a project for school but I am having a hard time finding information on how to do this properly.

I want to take the date put for the inspection_date and compare that to the local time, and if local time is greater than inspection_date, alert the user that they are past the inspection date.

Here is my class model

class Hive(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    hive_number = models.IntegerField()
    inspection_date = models.DateField()

My Serializer

class HiveSerializer(serializers.ModelSerializer):
    class Meta:
        model = Hive
        fields = ['id', 'hive_number', 'inspection_date', 'user_id']
        depth = 1
