Django模型对象到Javascript数组

Question

这个问题以前被问过几次，但在回答完之后我无法得到结果。我有一个Django模型。我将模型转换为JSON字符串：

    from django.core.serializers.json import DjangoJSONEncoder
    from django.core import serializers
    from .models import MonthData

    #Returns multiple rows
    monthData = MonthData.objects.filter(project=id)
    #Convert models to JSON string
    monthDataStr = serializers.serialize("json", monthData,cls=DjangoJSONEncoder)

在我的模板中，我想将JSON字符串转换为Javascript数组：

^{pr2}$

但是Javascript无法进行转换。JSON生成的字符串如下所示：

有没有一种标准的方法可以让Django模型的JSON字符串更“Javascript友好”？如果没有，有什么解决办法？在

如果我所要做的不是最佳实践，那么如何将Django模型数据发送到Javascript而不必逐行或逐值发送呢？在

Answer 1

我设法让它工作起来。我要做的就是：

var monthData = {{monthData|safe}};

不知怎么的JS发现它是一个没有解析任何东西的对象！在
