如何在 django 中添加多个地址？ [关闭]

Question

我正在尝试添加多个地址，但只创建了 1 个地址

这是models.py

class Customer(models.Model):
user = models.ForeignKey(User, on_delete = models.CASCADE)
name = models.CharField(max_length = 100)
locality = models.CharField(max_length = 200)
city = models.CharField(max_length = 50)
zipcode = models.IntegerField()
state = models.CharField(choices = STATE_CHOICES, max_length=50)

这是views.py

def address(request):
add = Customer.objects.filter(user=request.user)
return render(request, 'app/address.html', {'add':add})

这是地址.py

{% for ad in add %}
<div class="col-sm-6">
 <div class="card">
  <div class="card-body">
   <h3>Address {{forloop.counter}}</h3>
   <p>Name: {{ad.name}}</p>
   <p>Locality: {{ad.locality}}</p>
   <p>City: {{ad.city}}</p>
   <p>Pin Code: {{ad.zipcode}}</p>
   <p>State: {{ad.state}}</p>
  </div>
 </div>
</div>
{% endfor %}

这是 admin.py

@admin.register(Customer)
class CustomerModelAdmin(admin.ModelAdmin):
list_display = ['id', 'name', 'user', 'locality', 'city',
'zipcode', 'state'] 

@admin.register(Address)
class AddressModelAdmin(admin.ModelAdmin):
list_display = ['id', 'user', 'name', 'locality',
'city', 'state', 'zipcode']

你的意思是一个用户可以有很多地址吗？该模型显示每个用户的地址 在这种情况下，您应该添加新的模型地址才能继续。这里有一个例子： models.py文件

class Customer(models.Model):
    user = models.ForeignKey(User, on_delete = models.CASCADE)
    name = models.CharField(max_length = 100)

class Address(models.Model):
    user = models.ForeignKey(
        "Customer", on_delete=models.CASCADE, verbose_name="customer"
    )
    locality = models.CharField(max_length = 200)
    city = models.CharField(max_length = 50)
    zipcode = models.IntegerField()
    state = models.CharField(choices = STATE_CHOICES, max_length=50)

在views.py

def addresses(request):
    addresses = Address.objects.filter(user=request.user)
    return render(request, 'app/address.html', {'addresses':addresses})

在address.html

{% if addresses %}
    {% for ad in addresses %}
        <div class="col-sm-6">
            <div class="card">
                <div class="card-body">
                    <h3>Address {{forloop.counter}}</h3>
                    <p>Name: {{ad.user.name}}</p>
                    <p>Locality: {{ad.locality}}</p>
                    <p>City: {{ad.city}}</p>
                    <p>Pin Code: {{ad.zipcode}}</p>
                    <p>State: {{ad.state}}</p>
                </div>
            </div>
        </div>
    {% endfor %}
{% endif %}

文件admin.py

@admin.register(Customer)
class CustomerModelAdmin(admin.ModelAdmin):
    model = Customer
    list_display = ['id', 'name'] 

@admin.register(Address)
class AddressModelAdmin(admin.ModelAdmin):
    model = Address
    list_display = ['id', 'user', 'locality', 'city', 'state', 'zipcode']

注意：您应该在 list_display 中呈现模型中的可用字段
