Django serializer send array in object

Question

I have models like this:

class Model1(models.Model):
    time = models.DateTimeField(auto_now=True)

class Model2(models.Model):

    model1= models.ForeignKey(Model1, on_delete=models.CASCADE, related_name="my_list")
    f1 = models.FloatField()

I want to create endpoint for send data like this:

{"time":"123", "my_list":[{"f1":"123"}, {"f1":"123"}, {"f1":"123"}]}

This is my serializer

class TestSerializer(serializers.ModelSerializer):


 class Meta:
        model = Model1
        fields = ('id',
                  'time',
                  'my_list',)

How i can send json like i want? (

{"time":"123", "my_list":[{"f1":"123"}, {"f1":"123"}, {"f1":"123"}]}

)

Use ListField along with DictField as child

class TestSerializer(serializers.ModelSerializer):
    my_list = serializers.ListField(child=serializers.DictField())
    class Meta:
        model = Model1
        fields = ('id', 'time', 'my_list',)

Depending on how complex the objects in your list are, you may want to set child=serializers.JSONField .
