Django REST: How to change default field type of a ModelSerializer class
0
I am trying to overwrite serializer's data field, which is a CharField,like this:
from jsonfield import JSONField
class ActivitySerializer(serializers.ModelSerializer):
data = JSONField()
class Meta:
model = Activity
fields = ("date_added", "start_date", "data", "number", "athlete")
But when I try to print the representation of the serializer -print(repr(my_serializer)) - the type of field data remains unchanged:
ActivitySerializer(<Activity: START DATE: 2018-11-19 06:08:49+00:00, ID: 1973222369, DATE ADDED: 2018-11-20 18:07:32.818798+00:00>):
date_added = DateTimeField(read_only=True)
start_date = DateTimeField(required=False)
data = CharField(style={'base_template': 'textarea.html'})
number = IntegerField(required=False)
athlete = PrimaryKeyRelatedField(queryset=Athlete.objects.all(), required=False)
What am I doing wrong?

Change its type fromCharFieldtoJSONField

I guess it says CharFiels because it expects data to be a string, by default. But when you see it in the browser, you will see json data.

I will see JSON data, but with backslashes escaping double qoutes. This is becasue JSON is stored as string in model field , and then it is serialized again to string through serializers CharField. But I found solution to this by creating custom serializer field - my question is about someting else:)
