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,应该使用许多主板名称和价格填充数据库。
我的models.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称为fillDB.py:
import sys
import os
if __name__ == "__main__":
sys.path.append('/home/waleedasif322/Documents/cb/computerbuilder_masterrepo/computerbuilder/')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "computerbuilder.settings")
from builds.models import BuildsTable
mobo = BuildsTable.objects.all()
print mobo
moboDB = open("db.txt", "r")
lines = moboDB.read().split('\",')
print lines
def main():
global lines
global BuildsTable
for item in lines:
try:
mobo = BuildsTable(moboListing="%s" % item[0])
except BuildsTable.DoesNotExist:
mobo = 1
try:
price_local = BuildsTable(moboListing="%s" % item[1])
except BuildsTable.DoesNotExist:
price_local = 1
"""
if(BuildsTable.objects.filter(
moboListing = mobo, price = price_local).exists() == False):
"""
mydb = BuildsTable(moboListing = mobo, price = price_local)
print mydb
mydb.save()
main()
如何用主板列表填充数据库?

最佳答案
问题是mydb
无法保存,因为您正在将BuildsTable
对象设置为整数字段。考虑一下:
try:
price_local = BuildsTable(moboListing="%s" % item[1])
except BuildsTable.DoesNotExist:
price_local = 1
# ...
mydb = BuildsTable(moboListing = mobo, price = price_local)
您可以将
price
设置为BuildsTable
而不是整数。这行不通。顺便说一句,您的其他try-catch也很可疑,您在其中设置了
mobo = BuildsTable(moboListing="%s" % item[0])
,然后将mobo
用作moboListing
的值。最后,您知道整个脚本是一个肮脏的hack。从脚本操作Django的正确方法是编写custom Django admin commands。确实并不难,您将获得更强大,更可靠的解决方案。
