Question

我正在将JSON数据加载到“我的数据库”中，但给我错误- TypeError - the JSON object must be str, not 'list'

from django.shortcuts import render

# Create your views here.

import json
from .models import Movie

def detail(request):

    with open('movie_data.json', encoding='utf-8') as data_file:
        json_data = json.loads(data_file.read())
        print(type(json_data))

    json_dict = json.loads(json_data)
    for movie_data in json_dict:
        movie = Movie.create(**movie_data)
        # movie and genres created

Json文件-movie_data.json

[
  {
    "99popularity": 83.0,
    "director": "Victor Fleming",
    "genre": [
      "Adventure",
      " Family",
      " Fantasy",
      " Musical"
    ],
    "imdb_score": 8.3,
    "name": "The Wizard of Oz"
  },
  {
    "99popularity": 88.0,
    "director": "George Lucas",
    "genre": [
      "Action",
      " Adventure",
      " Fantasy",
      " Sci-Fi"
    ],
    "imdb_score": 8.8,
    "name": "Star Wars"
  },
]

我认为json应该转换为字典。我怎样才能做到这一点。我不知道是什么问题。我正在读取json文件。应该是字符串文件吗？

Answer 1

您不需要致电json.loads()两次。删除第二个呼叫。

Answer 2

如上所述，json.loads()不需要两次。并且当您在json_data = json.loads(data_file.read())使用它时，它会被构造成词典列表。

JSON对象必须为str，而不是“ list”-TypeError
