Question

这个问题是关于在选择器的选择中正确呈现html。这是我的代码：

models.py

from django.db import models
class Test(models.Model):
    area = models.FloatField(choices=((0, '0 mm&sup2;'), (0.5, '0.5 mm&sup2;')), default=0)

views.py

from django.shortcuts import render_to_response
from django.template import RequestContext
from django.forms import ModelForm
from models import Test

class TestForm(ModelForm):
    class Meta:
        model = Test

def test(request):
    form = TestForm()
    return render_to_response('test.html', RequestContext(request, {'form': form}))

的test.html

{{ form.area }}
{{ form.area|safe }}
{% autoescape off %}{{ form.area }}{% endautoescape %}

以上三个选项均未成功将选择器选项正确显示为0mm²而非0 mm²。怎么解决这个问题？

使用mark_safe函数使Django不会在模板中转义字符串

from django.utils.safestring import mark_safe
from django.db import models
class Test(models.Model):
    area = models.FloatField(choices=((0, mark_safe('0 mm&sup2;')), (0.5, mark_safe('0.5 mm&sup2;'))), default=0)

django：在选择器选项中呈现包含html的模板字段
