Django Custom Validation scenarios with Complex Nested Data Structures
I'm working on a project and hit a roadblock. I'm collaborating on a project where Does anyone know how to Could someone explain I'm working on a personal project and I'm working on a Django project where I need to validate a complex nested data structure for a custom form. I'm using Django 3.2 and have created a custom serializer that handles a dictionary containing multiple fields, some of which are lists of dictionaries. However, when I attempt to validate the input, I'm working with a `ValidationError` that doesn't provide enough detail about which part of the data is causing the scenario. Here’s a simplified version of my serializer: ```python from rest_framework import serializers class InnerItemSerializer(serializers.Serializer): id = serializers.IntegerField(required=True) value = serializers.CharField(max_length=100) class OuterItemSerializer(serializers.Serializer): name = serializers.CharField(max_length=50) items = InnerItemSerializer(many=True) class MyCustomSerializer(serializers.Serializer): outer_data = OuterItemSerializer(many=True) ``` I am trying to validate the following input: ```json { "outer_data": [ {"name": "Item 1", "items": [{"id": 1, "value": "Value 1"}, {"id": 2, "value": "Value 2"}]}, {"name": "Item 2", "items": [{"id": "invalid", "value": "Value 3"}]} ] } ``` When I run the serializer with this input, I get the following behavior: ``` ValidationError at /some-endpoint/ { 'outer_data': [ {'items': [{'id': ['A valid integer is required.'], 'value': ['This field is required.']}]}, {'name': ['This field is required.']} ]} ``` I've confirmed that the structure of the JSON is correct and matches the serializer. What I don’t understand is why the second object in the `outer_data` array is being reported as invalid when it contains the required `name` field. I've also tried using `is_valid(raise_exception=True)` to debug but the behavior messages are still quite vague. Is there a way to improve the granularity of the validation feedback or to correctly identify which parts of the nested structure are causing the scenario? Any insights would be greatly appreciated! Is this even possible? I'm developing on Debian with Python. Any pointers in the right direction? Am I missing something obvious?
