I want to access userId of current logged-in user. for that i need to pass the request object from one serialiser to another. Here's my code
class ThreadViewSerializer(serializers.ModelSerializer):
op = PostDetailViewSerializer(context={'request': request})
class Meta:
model = Thread
fields = ('id', 'title', 'op', 'group_id', 'type', 'reference_id', 'is_frozen', 'views', 'is_pinned')
In PostDetailViewSerializer, I want to pass request object but for that it requires self object. like this
request = self.context.get('request')
Thus, How can we pass the request object to PostDetailViewSerializer class in ThreadViewSerializer class. Please help me in this.

Here are two ways of achieving that:
- You can use a
SerializerMethodField
to access theself.context
(keep in mind that this a read-only serializer):
class ThreadViewSerializer(serializers.ModelSerializer):
op = serializers.SerializerMethodField()
def get_op(self, instance):
return PostDetailViewSerializer(instance=instance.op, context=self.context).data
class Meta:
model = Thread
fields = ('id', 'title', 'op', 'group_id', 'type', 'reference_id', 'is_frozen', 'views', 'is_pinned')
- You can override the
__init__
method of yourThreadViewSerializer
and pass the context then down to your fields:
class ThreadViewSerializer(serializers.ModelSerializer):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['op'] = PostDetailViewSerializer(context=self.context)
class Meta:
model = Thread
fields = ('id', 'title', 'op', 'group_id', 'type', 'reference_id', 'is_frozen', 'views', 'is_pinned')
