Question

我有一个包含变量的json字符串。

"country": {
    "name":"England",
    "city":"London",
    "description":"This country has a land mass of {{ info.1 }}km² and population is big as <span class=\"colorF88017\">{{ info.2 }} millions</span>.",
    "info":[
        null,
        [130395],
        [5479]
    ]
}

如您所见，这些变量链接到json文件中的列表。但是，当我在模板html中进行操作时：{{ country.description }}不会显示info.1 or info.2包含的内容。它只是将所有内容显示为文本。

如何显示字符串中变量的值？

from django.template.loader import render_to_string
def country_info(request):
    context = {}

    show = request.GET.get("show")
    if show:
        context["country"] = get_country_json()

    return render(request, 'country_info_index.html', context)

谢谢

使用render_to_string传递诸如follow之类的参数

description_template.html:
This country has a land mass of { info.1 }km² and population is big as <span class=\"colorF88017\">{ info.2 } millions</span>.

在render_to_string中使用此模板

from django.template.loader import render_to_string
template_name = "description_template.html"
description = render_to_string(template_name, 
  context={
     "info": description
  }
)

或使用f字符串

description =  f"This country has a land mass of { info.1 }km² and population is big as <span class=\"colorF88017\">{ info.2 } millions</span>."
