如何在Django中填充inlineformsets

# models.py
from django.db import models

class ParentModel(models.Model):
    name = models.CharField(max_length=100)

class ChildModel(models.Model):
    parent = models.ForeignKey(ParentModel, on_delete=models.CASCADE)
    child_name = models.CharField(max_length=100)

# forms.py
from django import forms
from django.forms import inlineformset_factory
from .models import ParentModel, ChildModel

ChildFormSet = inlineformset_factory(ParentModel, ChildModel, fields=('child_name',))

class ParentForm(forms.ModelForm):
    class Meta:
        model = ParentModel
        fields = ('name',)

# views.py
from django.shortcuts import render
from .models import ParentModel
from .forms import ParentForm, ChildFormSet

def my_view(request):
    parent = ParentModel.objects.get(pk=1)
    form = ParentForm(instance=parent)
    formset = ChildFormSet(instance=parent)

    if request.method == 'POST':
        form = ParentForm(request.POST, instance=parent)
        formset = ChildFormSet(request.POST, instance=parent)
        if form.is_valid() and formset.is_valid():
            form.save()
            formset.save()
            # 处理保存成功后的逻辑

    return render(request, 'my_template.html', {'form': form, 'formset': formset})

# my_template.html
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    {{ formset.management_form }}
    {% for form in formset.forms %}
        {{ form.as_table }}
    {% endfor %}
    <input type="submit" value="Save">
</form>
