以django形式显示布尔模型字段作为单选按钮，而不是默认的复选框 [英] Display a boolean model field in a django form as a radio button rather than the default Checkbox

问题描述

这是我怎么做的，以单选按钮Yes和No显示一个布尔模型字段。

This is how I went about, to display a Boolean model field in the form as Radio buttons Yes and No.

choices = ( (1,'Yes'),
            (0,'No'),
          )

class EmailEditForm(forms.ModelForm):

    #Display radio buttons instead of checkboxes
    to_send_form = forms.ChoiceField(choices=choices,widget=forms.RadioSelect)

    class Meta:
    model = EmailParticipant
    fields = ('to_send_email','to_send_form')

    def clean(self):
    """
    A workaround as the cleaned_data seems to contain u'1' and u'0'. There may be a better way.
    """

    self.cleaned_data['to_send_form'] = int(self.cleaned_data['to_send_form'])
    return self.cleaned_data

正如你在上面的代码中可以看到的，我需要一个干净的方法来转换输入字符串到整数，这可能是不必要的。

As you can see in the code above, I need a clean method that converts input string to an integer, which may be unnecessary.

做一个更好和/或djangoic的方法。如果是这样，那么如何？

Is there a better and/or djangoic way to do this. If so, how?

而不，使用 BooleanField 似乎引起更多的问题。对我来说似乎很明显但不是。为什么是这样的。

And no, using BooleanField seems to cause a lot more problems. Using that seemed obvious to me; but it isn't. Why is it so.

推荐答案

使用 TypedChoiceField 。

class EmailEditForm(forms.ModelForm):
    to_send_form = forms.TypedChoiceField(
                         choices=choices, widget=forms.RadioSelect, coerce=int
                    )
