如何在Django上使用Chartjs中的实用程序

我有一个简单Django项目，它在一个确定的页面上显示一些图表，所以当我尝试从Chartjs复制一些示例时，我看到它们使用了Utils模块，当我在views.py文件中进行同样的调用时，它最终返回错误，因为 *Utils没有在任何地方定义 *

@staff_member_required
def chart(request, year):
    persons = Persons.objects.filter(time__year=year)
    grouped_purchases = purchases.annotate(price=F('item__price')).annotate(month=ExtractMonth('time'))\
        .values('month').annotate(average=Sum('item__price')).values('month', 'average').order_by('month')

    sales_dict = get_year_dict()

    for group in grouped_purchases:
        sales_dict[months[group['month']-1]] = round(group['average'], 2)

    DATA_COUNT = 7;
    NUMBER_CFG = {count: DATA_COUNT, min: -100, max: 100}

    return JsonResponse({
        'title': f'Persons {year}',
        'data': {
            'labels': Utils.months({count: 7}),
            'datasets': [{
                'label': 'Amount ($)',
                'backgroundColor': Utils.CHART_COLORS.red,
                'borderColor': colorPrimary,
                'data': Utils.numbers(NUMBER_CFG),
            }]
        },
    })

这是html文件的头

<head>
    <title>Statistics</title>
    <script src="https://cdn.jsdelivr.net/npm/chart.js@2.9.4"></script>
    <script src="https://code.jquery.com/jquery-3.5.1.min.js" crossorigin="anonymous"></script>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-v4-grid-only@1.0.0/dist/bootstrap-grid.min.css">
  </head>

我知道Utils是一个JavaScript文件，我不能在Python中导入它，有什么方法可以解决这个问题吗？

Utils是由chart.js自己编写的文件，它没有随库一起提供，所以除非你自己实现它，否则你不能使用它。
