Django Forms Not Validating List of Dictionaries as Input for ModelForm
I'm wondering if anyone has experience with I'm working on a personal project and I'm working with Django 4.1 and trying to use a ModelForm to handle a list of dictionaries coming from a JSON request. Each dictionary represents a related model and should be validated as part of the parent model. However, I'm working with an scenario where the form is failing to validate the list, throwing a `ValidationError` that says 'This field is required' for each dictionary in the list. Here's a snippet of the code: ```python from django import forms from myapp.models import ParentModel, ChildModel class ChildModelForm(forms.ModelForm): class Meta: model = ChildModel fields = ['name', 'value'] class ParentModelForm(forms.ModelForm): children = forms.JSONField() # expecting a list of dictionaries class Meta: model = ParentModel fields = ['title', 'children'] def clean_children(self): children_data = self.cleaned_data['children'] if not isinstance(children_data, list) or not all(isinstance(item, dict) for item in children_data): raise forms.ValidationError('Children must be a list of dictionaries.') return children_data ``` In my view, I'm processing the incoming JSON like this: ```python from django.http import JsonResponse from django.views import View class ParentCreateView(View): def post(self, request): form = ParentModelForm(request.POST) if form.is_valid(): form.save() return JsonResponse({'status': 'success'}, status=201) return JsonResponse({'errors': form.errors}, status=400) ``` When I send a request with a JSON body like this: ```json { "title": "Parent Title", "children": [ {"name": "Child 1", "value": 10}, {"name": "Child 2", "value": 20} ] } ``` The `children` field is being recognized as required but isn't validating properly. I tried changing the field type from `JSONField` to a custom field that would handle the list of dictionaries better, but that led to more issues. What am I missing in my approach to validate this input correctly? I'm working on a application that needs to handle this. I'd really appreciate any guidance on this. I'm developing on Windows 10 with Python. Thanks for your help in advance!
