Django中的RadioSelect（）小部件的模板呈现问题

Question

我想通过使用Django中提供的RadioSelect（）小部件呈现一个（默认）单选按钮，但每当我使用它时，输出都是空白的。但是，如果我让django窗体加载默认渲染器，而不是使用选项打印出下拉框。我在这里粘贴我为此编写的代码摘要。

# In models.py 

AUDIO_SETTING_CHOICES = (
         ('RESTART', 'Play audio from the beginning.'), 
         ('CONTINUE', 'Continue playing previous audio (if same).'), 
    ) 

audio_setting = models.CharField(max_length=20, choices=AUDIO_SETTING_CHOICES, default='RESTART') 

# In forms.py 

class ChapterItemForm(forms.ModelForm): 
    def __init__(self, user=None, *args, **kwargs): 
     self.user = user 
     super(ChapterItemForm, self).__init__(*args, **kwargs) 

     self.fields['audio_setting'] = forms.ChoiceField(label="How to play the audio?", 
                 widget=forms.RadioSelect()) 

# In template 
<Form> 
... 
audio setting: {{ form.audio_setting }} <br /> 
... 

所以对我可能是做错了任何指针？

你不传递任何选择的ChoiceField

self.fields['audio_setting'] = forms.ChoiceField(choices=AUDIO_SETTING_CHOICES, label="How to play the audio?", widget=forms.RadioSelect())
