如何在Django表单中仅加载活动数据

# models.py
from django.db import models

class Item(models.Model):
    name = models.CharField(max_length=100)
    is_active = models.BooleanField(default=True)

# forms.py
from django import forms
from .models import Item

class ActiveItemForm(forms.ModelForm):
    class Meta:
        model = Item
        fields = ['name', 'is_active']

    def __init__(self, *args, **kwargs):
        super(ActiveItemForm, self).__init__(*args, **kwargs)
        # 过滤活动数据
        self.fields['name'].queryset = Item.objects.filter(is_active=True)

# views.py
from django.shortcuts import render
from .forms import ActiveItemForm

def active_items_view(request):
    form = ActiveItemForm()
    return render(request, 'active_items.html', {'form': form})
