Django错误：TypeError:int（）参数必须是字符串或数字，而不是“BuildsTable”

Question

我正在尝试将对象保存到数据库，但出现错误：

TypeError: int() argument must be a string or a number, not 'BuildsTable'

我有一个单独的脚本，应该填充我的数据库与许多主板的名称，和价格。在

我的模型.py看起来像这样：

from django.db import models

# Create your models here.

class BuildsTable(models.Model):
    id = models.AutoField(primary_key=True)
    moboListing = models.CharField(max_length=200)
    price = models.IntegerField()

我的数据库填充文件名为填充数据库.py公司名称：

^{pr2}$

如何用主板列表填充数据库？在

Answer 1

问题是mydb无法保存，因为您正在将BuildsTable对象设置为一个整数字段。考虑一下这个：

try:
    price_local = BuildsTable(moboListing="%s" % item[1])
except BuildsTable.DoesNotExist:
    price_local = 1
# ...
mydb = BuildsTable(moboListing = mobo, price = price_local)

好了，将price设置为BuildsTable，而不是一个整数。这行不通。在

顺便说一句，您的另一个try-catch也很可疑，您设置mobo = BuildsTable(moboListing="%s" % item[0])，然后使用mobo作为moboListing的值。在

最后，你知道整个脚本是一个肮脏的黑客。从脚本操作Django的正确方法是编写custom Django admin commands。这其实并不难，而且您将获得更健壮、更可靠的解决方案。在
