基数为 10 的 int() 的无效文字：'...aa53' - Django

Question

我有一个 django 项目，我正在尝试从 json 响应中将某些内容保存到我的数据库中。表中的字段是字符字段。返回的响应是一个字符串。我想通过创建一个新的数据库对象来简单地将响应保存在数据库中。我收到以下错误，我不确定为什么会这样。

invalid literal for int() with base 10: '5..6003463aa53'

这是我的代码：

for node in nodes:
node_json = node.json
node_id = node_json['_id']
print(node_id)
node_name = node_json['info']['nickname']
print(node_name)
node_class = node_json['info']['class']
print(node_class)
node_bank_name = node_json['info']['bank_name']
final_bank_name = str(node_bank_name)
print(node_bank_name)
new_account = SynapseAccounts.objects.create(
     user = currentUser,
     name = node_name,
     account_id = node_id,
     account_class = node_class,
     bank_name = final_bank_name,
)
print(new_account)

我什至强制了字符串。

这是我为桌子准备的模型：

class SynapseAccounts(models.Model):
     user = models.ForeignKey(User, on_delete=models.CASCADE)
     name = models.CharField(max_length=100, default='Bank Account')
     account_id = models.IntegerField(default=0)
     account_class = models.CharField(max_length=50, default='Checking')
     bank_name = models.CharField(max_length=150, default='DefaultBank')
     create = models.DateTimeField(auto_now_add=True)

这是完整的堆栈跟踪

Answer 1

在我看来，您的 account_id 字段 (account_id = models.IntegerField(default=0)) 正在接收不是整数的数据。

你确定node_json['_id'] 返回一个整数吗？因为您使用该值来设置 node_id，然后在创建 account_id 字段时使用该值。

注意：5a00e02cf9bd86003463aa53 看起来像 id，但不是整数。
