python - DJango:格式化json序列化

Question

我有以下 DJango View

def company(request):
    company_list = Company.objects.all()
    output = serializers.serialize('json', company_list, fields=('name','phonenumber','email','companylogo'))
    return HttpResponse(output, content_type="application/json")

结果如下:

[{"pk": 1, "model": "test.company", "fields": {"companylogo": null, "phonenumber": "741.999.5554", "name": "Remax", "email": "home@remax.co.il"}}, {"pk": 4, "model": "test.company", "fields": {"companylogo": null, "phonenumber": "641-7778889", "name": "remixa", "email": "a@aa.com"}}, {"pk": 2, "model": "test.company", "fields": {"companylogo": null, "phonenumber": "658-2233444", "name": "remix", "email": "b@bbb.com"}}, {"pk": 7, "model": "test.company", "fields": {"companylogo": null, "phonenumber": "996-7778880", "name": "remix", "email": "a@aba.com"}}]

我的问题:1.我可以控制字段的顺序吗2.我可以更改字段名称吗3. 我期待在浏览器中看到带有缩进的结果，即看到这样的内容而不是一行长行:

[
  {
     "pk": 1, 
     "model": "test.company", 
     "fields": 
     {
         "companylogo": null, 
         "phonenumber": "741.999.5554", 
         "name": "Remax", 
         "email": "home@remax.co.il"
     }
  }, 
  {
     "pk": 4, 
     "model": "test.company", 
     "fields": 
     {
        "companylogo": null,  
        "phonenumber": "641-7778889", 
        "name": "remixa", 
        "email": "a@aa.com"
     }
  }, 
  ....
 }

]

Answer 1

你可以通过这种方式得到漂亮的格式:

return JsonResponse(your_json_dict, json_dumps_params={'indent': 2})
