Django - 如何翻译表单字段的静态选择

问：

我有一个表格，可以在多语言文本中更新用户的详细信息。在性别下拉列表中，它不会翻译性别选择，如下所示：

我尝试在 model.py 文件中使用选项。我在 .po 文件中看到它们。它仍然不起作用。我做错了什么？gettext_noop

model.py

from django.utils.translation import gettext_noop
Account_sex = [('male',gettext_noop('Male')),('female',gettext_noop('Female'))]  #List of tuples with choices. First one is what's stored in DB and second what is shown in html.

class Account(AbstractBaseUser):
    first_name = models.CharField(max_length=50)
    email = models.EmailField(max_length=100, unique=True)
    sex = models.CharField(max_length=10, blank=True, null=True, choices=Account_sex, default='male') 

view.py

@login_required(login_url='login')
def edit_profile(request):
    if request.user.is_authenticated:
        current_user = Account.objects.get(id=request.user.id)
        form = EditProfileForm(request.POST or None, instance=current_user)
        if form.is_valid():
            form.save()
            messages.success(request,("Your profile has been updated!"))
            return redirect('dashboard')

        return render(request, 'accounts/edit_profile.html',context={'form':form}) #
    else:
        messages.success(request,('You must be logged in!'))
        return redirect('login')

edit_profile.html

<div class="col col-auto form-group">
 <label>{% trans "Sex" %}</label>
 {{ form.sex }}
</div>
