Exception Type: IntegrityError at /checkout/ 
Exception Value: insert or update on table "orders_order" violates foreign key constraint "billing_address_id_41625ebca5013523_fk_accounts_useraddress_id" 
DETAIL: Key (billing_address_id)=(1) is not present in table "accounts_useraddress". 

Answer 1

重要细节是在这一行：

DETAIL: Key (billing_address_id)=(1) is not present in table "accounts_useraddress". 

的问题是，您正试图将订单与帐单地址相关联尚未存在于数据库中。

在您的代码中，您需要确保帐单地址已保存到数据库，然后再尝试使用外键保存与其相关的对象。
