My Serializer
class LessonPlanSerializer(serializers.ModelSerializer):
uploaded_file=serializers.ListField(child=serializers.FileField(max_length=2000)
class Meta:
model = LessonPlan
fields=['id', 'planner', 'title', 'details', 'uploaded_file',]
My post request contains title, details, and multiple files that will post in the child model LessonStudyMaterial so I have added the uploaded_file field to validate data while posting but it showing an error
