python - 在 Get 请求中返回对象时出现 AttributeError '' 对象没有属性 'get'

Question

这是请求网址:GET/api/v1/companies/profile/?name=TestFirma 我对 django 比较陌生，这是我第一次尝试在 django 中使用 GET 请求传递参数。

我已经使用记录器进行了测试，名称(TestFirma)实际上传递给 get_object。

我不明白为什么 Company 应该有一个 get 方法？我在这里误解了什么？

def get_object(request, name):
    name = request.GET.get('name', '')
    if name is not None:
        company = Company.objects.get(name=name)
        return company

我假设您想要返回 Company 对象的 JSON 响应。如果这就是您想要的，那么您应该序列化该对象，然后将其作为 HttpResponse 对象返回。

import json

from django.http import HttpResponse
from django.core import serializers

def get_object(request, name):
    name = request.GET.get('name', '')
    if name is not None:
        obj = Company.objects.get(name=name)
        company = serializers.serialize('json', [obj,])
        struct = json.loads(company)
        data = json.dumps(struct[0])
        return HttpResponse(data, content_type='json')
