如何在django中使用默认地址进行保存

from django.db import models

class Address(models.Model):
    street = models.CharField(max_length=100)
    city = models.CharField(max_length=50)
    state = models.CharField(max_length=50)
    # 其他字段...

class Address(models.Model):
    street = models.CharField(max_length=100)
    city = models.CharField(max_length=50, default="New York")
    state = models.CharField(max_length=50, default="NY")
    # 其他字段...

from django.shortcuts import render, redirect
from .models import Address
from .forms import AddressForm

def save_address(request):
    if request.method == 'POST':
        form = AddressForm(request.POST)
        if form.is_valid():
            form.save()  # 保存表单数据到数据库
            return redirect('success')
    else:
        form = AddressForm()

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

from django import forms
from .models import Address

class AddressForm(forms.ModelForm):
    class Meta:
        model = Address
        fields = '__all__'

<form method="post" action="{% url 'save_address' %}">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">保存</button>
</form>
