Question

新手在这里。我正在为使用从wrapsnet.org下载的csv的网站编写加载程序脚本。当我尝试运行加载程序时，我收到消息＆＃34; TypeError：int（）参数必须是字符串，类似字节的对象或数字，而不是＆＃39; list＆＃39;。＆＃34; < / p>

Loader.py：

import os, sys, string, csv, datetime, time, django, pytz

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "refugees.settings")

django.setup()

from reports.models import Country, State, City, RefugeeReport

from django.template.defaultfilters import slugify, urlize
from django.core.exceptions import ObjectDoesNotExist

reader = csv.reader(open("refugees0216.csv"), dialect=csv.excel)
next(reader)
for row in reader:

    refstate = row[0]
    refstate_slug = slugify(refstate)
    refstateid, refstateadded = State.objects.get_or_create(name=refstate, name_slug=refstate_slug)

    ref = RefugeeReport(country=reforiginid, state=refstateid, city=popcityid, year=row[1], city_total=row[6], state_total=row[2], country_total=row[4], all_countries=[7])
    print(ref)
    ref.save()

Models.py：

from django.db import models

class Country(models.Model):
    name=models.CharField(max_length=255)
    name_slug=models.SlugField()
    def __str__(self):
        return self.name

class State(models.Model):
    name=models.CharField(max_length=255)
    name_slug=models.SlugField()
    def __str__(self):
    return self.name
    def get_absolute_url(self):
        return "/reports/%s" % self.name_slug

class City(models.Model):
    state=models.ForeignKey(State)
    name=models.CharField(max_length=255)
    name_slug=models.SlugField()
    def __str__(self):
        return self.name
    def get_absolute_url(self):
        return "/reports/%s/%s" % (self.state.name_slug, self.name_slug)

        return "%s, %s from %s" % (self.city.name_slug, self.state.name_slug, self.year)
    def get_absolute_url(self):
        return "/reports/%s/%s/%s" % (self.city.name_slug, self.state.name_slug, self.year)

如果您有任何建议，我将不胜感激。

更新：用于打印所有变量的回溯

  File "loader.py", line 29, in <module>
    print(ref, country, state, city, year, city_total, state_total, country_total, all_countries)
NameError: name 'country' is not defined

Answer 1

我认为你在这一行上有错误：

  ref = RefugeeReport(country=reforiginid, state=refstateid, city=popcityid, year=row[1], city_total=row[6], state_total=row[2], country_total=row[4], all_countries=[7])

看看all_countries属性，我认为这是不正确的：

all_countries=[7]

将其更改为：

 all_countries=row[7]
