Django Serilizer: Getting an ordered dictionary in embeded serializer

I'm one serializer inside another to show information from one model, and selected fields from another in the same response.



This looks like this:



class SimpleRouteClientConstraintSerializer(serializers.ModelSerializer):

name = serializers.SerializerMethodField()

def get_name(self, obj):
default_constraint = RouteDefaultConstraint.objects.get(pk=obj.route_default_constraint_id)
return default_constraint.name

class Meta:
model = RouteClientConstraint
fields = ('name', 'value')

class RouteSerializer(serializers.ModelSerializer):
...
# Calling first serializer here
routeClientConstraints = SimpleRouteClientConstraintSerializer(many=True, required=False)
...

class Meta:
model = Route
fields = (..., 'routeClientConstraints', ...)
depth = 1


When running the RouteSerilalizer, i want a response:



'routeClientConstraints': [{
'name': 'my name'
'value': 'confused'
},
...
]


If i use the serializer as in the code above, I get



'routeClientConstraints': [
OrderedDict([
('name', 'Minimum life boats'),
('value', '6')
])
]


I tried changing the serializer to: routeClientConstraints = SimpleRouteClientConstraintSerializer(many=True, required=False).data, which i expected would give me json format, but i got this:



'routeClientConstraints': [
OrderedDict([
('id', 1),
('value', '6'),
('created_at', '2018-11-10T14:17:39.263848Z'),
('updated_at', '2018-11-10T14:17:39.263861Z'),
('route_default_constraint', 1),
('route', 1)])
]


How do i return a list of dictionaries?

  • An OrderedDict is a dictionary. When it is converted to JSON it will do the right thing.
