如何在django中插入Checkbox

Question

你好我想用复选框字段创建数据但是当我使用widget RadioSelect时数据无法保存在数据库中

这是forms.py

class VehicleAttribute(forms.ModelForm):
    OPERATION = [('production','Production Vehicle'),('supporting','Supporting Vehicle')]
    PAYLOAD_METER = [('yes','Yes'),('no','No')]
    NUMBER_STRUT = [('0','0'),('3','3'),('4','4')]

    operation = forms.ChoiceField(widget=forms.RadioSelect, choices = OPERATION)
    payload_meter = forms.ChoiceField(widget=forms.RadioSelect, choices = PAYLOAD_METER)
    number_of_strut_pressure = forms.ChoiceField(widget=forms.RadioSelect, choices = NUMBER_STRUT)

    class Meta:
        model  = Vehicle_attribute      
        fields  = ['operation','payload_meter','number_of_strut_pressure']

这是views.py

def data_vehicle_add(request):
    if request.method == "POST":
        form = VehicleAttribute(request.POST)
        if form.is_valid():
            post = form.save(commit=False)
            post.save()
            return redirect('data_vehicle_add.html', pk=post.pk)
    else:
        form = VehicleAttribute()
    return render(request,'data_vehicle_add.html', {'form':form}, context_instance=RequestContext(request))

你可以帮我解决这个问题吗？
