Django 4.1 Formset not retaining data after validation failure
I'm migrating some code and I'm having trouble with a Django formset where the data doesn't seem to continue after validation errors. I'm using Django 4.1, and my formset is designed to allow users to add multiple entries for a related model. When I submit the formset, if any of the forms contain validation errors, the entire formset reloads, but the filled data is lost. Here's a simplified version of my view: ```python from django.forms import modelformset_factory from django.shortcuts import render, redirect from .models import MyModel from .forms import MyModelForm def my_view(request): MyModelFormSet = modelformset_factory(MyModel, form=MyModelForm, extra=1) if request.method == 'POST': formset = MyModelFormSet(request.POST) if formset.is_valid(): formset.save() return redirect('success_url') else: formset = MyModelFormSet(queryset=MyModel.objects.all()) return render(request, 'my_template.html', {'formset': formset}) ``` In my template, I'm rendering the formset as follows: ```html <form method="post"> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} {{ form.as_p }} {% endfor %} <button type="submit">Submit</button> </form> ``` I've checked that I'm correctly including the management form, and I'm also using a CSRF token. However, when validation fails, the formset shows empty instead of retaining the data that was inputted. I've tried debugging the formset and ensuring that I'm passing the `POST` data correctly, but I still face the same scenario. Has anyone encountered a similar question or can offer a solution? Thanks! Has anyone else encountered this?
