Question

我收到错误TypeError：字符串索引必须是整数.Traceback说

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Users/XXX/testapp/app/views.py", line 164, in <module>
    user1 = User.objects.filter(user_id=row_data['user_id']).exists()
TypeError: string indices must be integers

我写了

#coding:utf-8
from django.shortcuts import render
import xlrd
from .models import User

book = xlrd.open_workbook('../data/excel1.xlsx')
sheet = book.sheet_by_index(1)

def build_employee(employee):
  if employee == 'leader':
     return 'l'
  if employee == 'manager':
     return 'm'
  if employee == 'others':
     return 'o'

for row_index in range(sheet.nrows):
  rows = sheet.row_values(row_index) 
  is_man = rows[4] != ""
  emp = build_employee(rows[5])
  user = User(user_id=rows[1], name_id=rows[2], name=rows[3], 
              age=rows[4],man=is_man,employee=emp)
  user.save()

files = glob.glob('./user/*.xlsx')

for x in files:
    if "$" not in x:
      book3 = xlrd.open_workbook(x)
      sheet3 = book3.sheet_by_index(0)
      cells = [
    ]
      data_dict = OrderedDict()
      for key, rowy, colx in cells:
         try:
            data_dict[key] = sheet3.cell_value(rowy, colx)
         except IndexError:
            data_dict[key] = None

      for row_number, row_data in data_dict.items():
          user1 = User.objects.filter(user_id=row_data['user_id']).exists()
          if user1:
             user1.__dict__.update(**data_dict)
             user1.save()

我真的不明白为什么会发生这个错误，因为我知道data_dict是字典类型，所以我使用items（）进行迭代。我也无法理解哪些索引必须是整数。我怎么能解决这个问题？我该怎么写呢？ data_dict就像

OrderedDict([('user_id', '1'), ('name', 'Blear'), ('nationality', 'America'), ('domitory', 'A'), ('group', 1)], [('user_id', '1'), ('name', 'Blear'), ('nationality', 'America'), ('domitory', 'A'), ('group', 1)], [('user_id', '1'), ('name', 'Blear'), ('nationality', 'America'), ('domitory', 'A'), ('group', 1)])

TypeError：字符串索引必须是整数，我使用items（）进行迭代
