自定义RadioSelect

您好，我有一个带有 ChoiceField 的表单，其小部件设置为 RadioSelect

Now 以覆盖默认的 html 输出，需要像这样子类化 RadioFieldRenderer：

class SimpleRadioFieldRenderer(forms.widgets.RadioFieldRenderer):

    def render(self):
        """Outputs widget without <ul> or <li> tags."""
        return mark_safe(u'\n'.join([u'%s'
                % force_unicode(w.tag()) for w in self]))

现在一切都很好，除了我希望能够从模板一次渲染 1 个单选按钮。像这样的事情：

{{ form.myfield.0 }}}

或者也许将它挂在小部件本身上：

{{ form.myfield.field.widget.0 }}

令我烦恼的是 RadioFieldRenderer 已经实现了 __get_item__ 来获取一个 RadioInput。问题是渲染器不包含数据，小部件也不包含数据。我真的不想乱搞 Field 和 BoundField。

我需要在每个单选按钮之前/之后注入 html，并且我希望它在模板中完成。从代码来看，这很容易。

欢迎任何想法。

Hello I have a form with ChoiceField whose widget is set to RadioSelect

Now to override default html output one needs to subclass RadioFieldRenderer like this:

class SimpleRadioFieldRenderer(forms.widgets.RadioFieldRenderer):

    def render(self):
        """Outputs widget without <ul> or <li> tags."""
        return mark_safe(u'\n'.join([u'%s'
                % force_unicode(w.tag()) for w in self]))

All is good now except I'd like to be able to render 1 radio button at a time from template.
Something like this:

{{ form.myfield.0 }}}

Or perhaps hanging it onto widget itself:

{{ form.myfield.field.widget.0 }}

What bugs me is that RadioFieldRenderer already implements __get_item__ to get just one RadioInput. The problem is that the renderer does not contain data, neither does the widget. And I'd really hate to mess with Field and BoundField.

I need this to inject html before/after each radiobutton and I'd like it to be done in the template. From the code it would be easy.

Any ideas are welcome.
