Django 查询数据库返回JSON的实现

import json
from django.http import HttpResponse
from django.core import serializers
def db_to_json(request):
    scripts = Scripts.objects.all()[0:1]
    json_data = serializers.serialize('json', scripts)
    return HttpResponse(json_data, content_type="application/json")

[{
 "fields": {
  "script_content": "abc",
  "script_type": "1"
 },
 "model": "home_application.scripts",
 "pk": "03a0a7cf-567a-11e9-8566-9828a60543bb"
}]

import json
from django.http import HttpResponse
from django.core import serializers
def db_to_json2(request):
    # 和前端约定的返回格式
    result = {"message": 'success', "code": '0', "data": []}
    scripts = Scripts.objects.all()[0:1]
    # 序列化为 Python 对象
    result["data"] = serializers.serialize('python', scripts)
    # 转换为 JSON 字符串并返回
    return HttpResponse(json.dumps(result), content_type="application/json")

{
 "message": "success",
 "code": "0",
 "data": [{
  "fields": {
   "script_content": "abc",

  },
  "model": "home_application.scripts",
  "pk": "03a0a7cf-567a-11e9-8566-9828a60543bb"
 }]
}

from django.forms.models import model_to_dict
from django.http import HttpResponse
import json
def obj_json(request):
    pk = request.GET.get('script_id')
 
    script = Scripts.objects.get(pk=pk)
    # 转为字典类型
