python - Django 将错误列表输出为字符串而不是 html

Question

我正在尝试自定义 django 中的默认错误列表。我试过关注 the docs ，但问题是假设的 html 被输出为文本而不是 html:

我不太确定为什么会这样，因为代码几乎是从文档中复制粘贴的。代码:

表格.py

class DivErrorList(ErrorList):
    def __str__(self):
        return self.as_divs()

    def as_divs(self):
        if not self: return ''
        return '<div class="test">%s</div>' % ''.join(['<div class="error">%s</div>' % e for e in self])

View .py

def addUser(request):    
    add_user_form = AddUserForm()
    messages.warning(request, 'message')

    if request.method == 'POST':
        add_user_form = AddUserForm(request.POST, error_class=DivErrorList)

        if add_user_form.is_valid():
            user = add_user_form.save()
            customer_group = Group.objects.get(name = 'group_name')
            user.roles.add(customer_group)
            messages.success(request, 'message')
            return redirect('users')

        else:
            messages.error(request, 'message')

    context = {
        'add_user_form': add_user_form,
    }

    return render(request, 'users/backend/user/user_add.html', context)

html

<div class="w-full mt-6">
    {% include 'components/typography/form_label.html' with label='Gjenta passord' %}
    {{ add_user_form.password2 }}
    {{ add_user_form.password2.errors }}
</div>

您需要将字符串标记为“安全”，即:

return '<div class="test">%s</div>' % ''.join(['<div class="error">%s</div>' % e for e in self])

应该是

return mark_safe('<div class="test">%s</div>' % ''.join(['<div class="error">%s</div>' % e for e in self]))

mark_safe 的来源:

from django.utils.safestring import mark_safe
