如何在 django 中进行统计

Question

我正在使用 django fobi 来允许用户创建自己的表单。我想根据这些表格制作一些报告和统计数据。

我有一个工作 python 代码，但我不知道如何在 django 工作模板中“翻译”该代码。

数据如下：

saved_data = '''
  [
       [{
           "label": "Question 1?",
           "html_name": "question_1",
           "first_name": "John",
           "last_name": "Doe",
           "email": "john@doe.com",
           "answer": "Yes"
         }, {
           "label": "Question 2?",
           "html_name": "question_2",
           "first_name": "John",
           "last_name": "Doe",
           "email": "john@doe.com",
           "answer": ["Red", "White"]
       }],
       [{
           "label": "Question 1?",
           "html_name": "question_1",
           "first_name": "Jane",
           "last_name": "Mary",
           "email": "mary@jane.com",
           "answer": "No"
         }, {
           "label": "Question 2?",
           "html_name": "question_2",
           "first_name": "Jane",
           "last_name": "Mary",
           "email": "mary@jane.com",
           "answer": ["Red", "Black"]
         }]
  ]

'''

data = json.loads(saved_data)

answer = {}

for x in data:
    for y in x:
        if type(y['answer']) is list:
            for an in y['answer']:
                answer.setdefault(y['label'], {})\
                    .setdefault('answer', []).append(an)
                answer.setdefault(y['label'], {}).setdefault('full_name', []).append(y['first_name'] + ' ' + y['last_name'])
                answer.setdefault(y['label'], {}).setdefault('email', []).append(y['email'])
        elif type(y['answer']) is str:
            answer.setdefault(y['label'], {})\
                .setdefault('answer', []).append(y['answer'])
            answer.setdefault(y['label'], {}).setdefault('full_name', []).append(y['first_name'] + ' ' + y['last_name'])
            answer.setdefault(y['label'], {}).setdefault('email', []).append(y['email'])

for questions, answers in answer.items():
    print('\n', questions)
    counting = Counter(answers['answer'])
    for key, value in counting.items():
        print(key, value)
        for answer in zip(answers['full_name'], answers['answer']):
            if key == answer[1]:
                print(answer[0])

我怎样才能使它在 django 1.11 模板中工作？

Answer 1

您需要将其从view 传递到template。例如，您可以使用基于函数的视图来包装该逻辑并将其放入 views.py。您必须在 urls.py 中添加一个路由并让该视图返回一个模板。

在模板中，您可以for 循环遍历答案项并根据需要显示它们。
