{'test': <Test: BOFEGRI_CGC_M: 2c942c01f8bfds498581a5d47d75fc020b-Started>, 'answers': <QuerySet [<TestQuestionAnswer: 2c942c01f8b4498581a5d47d75fc020b: question nr. 3, answer nr. 1, correct True>, <TestQuestionAnswer: 2c942c01f8b4498581a5d47d75fc020b: question nr. 3, answer nr. 2, correct False>, <TestQuestionAnswer: 2c942c01f8b4498581a5d47d75fc020b: question nr. 3, answer nr. 3, correct False>, <TestQuestionAnswer: 2c942c01f8b4ds98581a5d47d75fc020b: question nr. 3, answer nr. 4, correct False>]>, 'test_question': <TestQuestion: 2c942c01f8b4498581a5d47d75fc020b: nr=3>, 'test_button_list': [[{'number': 1, 'answered': False, 'correct': False}, {'number': 2, 'answered': False, 'correct': False}, {'number': 3, 'answered': False, 'correct': False}, {'number': 4, 'answered': False, 'correct': False}, {'number': 5, 'answered': False, 'correct': False}]], 'view': <tests.views.DifficultTestView object at 0x7f44e7e9c550>, 'form': <TestForm bound=False, valid=Unknown, fields=(AnswerRadioButton1;AnswerRadioButton2;AnswerRadioButton3;AnswerRadioButton4)>}

在我看来：

context = self.get_context_data()
        print(self.get_context_data())
        html = render_to_string('difficult_test.html', context)

        if self.request.is_ajax():

            return http.JsonResponse({"html":html, "context":context})
        return response

如果我尝试序列化，我会收到以下响应：TypeError: is not JSON serializable

【解决方案1】：

如果您想问如何序列化 python 对象，那么 'pickle' 内置库允许该功能。

例子：

import pickle

mapping = {'earth': [432, 762, 3297]}

result = pickle.dumps(mapping)
print(result)
