Question

class Customer(models.Model):    
      customer_id = models.AutoField( primary_key=True)   
      customer_name = models.TextField()
      billing_address = models.ForeignKey(Address,on_delete=models.CASCADE,related_name='Billing')
  shipping_address = models.ForeignKey(Address,on_delete=models.CASCADE,related_name='Shipping')

class Address(models.Model):      
     address_id = models.AutoField(primary_key=True)     
     address = models.CharField(max_length=200, blank=True)    
     city= models.CharField(max_length=200, blank=True)

现在，我的问题是我有一个客户模型和地址模型，客户有一个帐单地址和送货地址，而客户有一个地址外键。但是地址模型没有客户外键（如果地址有客户外键我自己也可以这样做。）

在创建客户时，用户必须输入帐单邮寄地址和送货地址。我怎么能这样做？

您需要将Address模型中的ForeignKey设置为Customer ..并且您可以添加address_type选项字段以指示开票/发货。

class Customer(models.Model):    
    customer_id = models.AutoField( primary_key=True)   
    customer_name = models.TextField()


class Address(models.Model):      
    BILLING='B'    
    SHIPPING='S'
    ADDRESS_TYPE=((BILLING,'Billing'),(SHIPPING,'Shipping'))  
    address_type=models.CharField(max_length=1, choices=ADDRESS_TYPE, verbose_name="address_type")
    customer=models.ForeignKey(Customer, on_delete=models.CASCADE, related_name='addresses', null=False)
    address_id = models.AutoField(primary_key=True)     
    address = models.CharField(max_length=200, blank=True)    
    city= models.CharField(max_length=200, blank=True)

然后创建inlineformset，如

AddressInlineFormSet = inlineformset_factory(Customer, Address, can_delete=False)

Django 2.0中的两个模型字段在一个表单中？
