Django Queryset格式

如何在此模型表单中创建查询集。这是我的密码

Class Sample(forms.ModelForm):  
    class Meta:  
        model = Customer  
        fields = ('name','address',)  
        widgets = {  
            'name' : Select(attrs={'class':'span2'}),  
            'address' : TextInput(attrs={'class':'span4'}),  
             }  
        queryset = {'name': User.objects.filter(type_id=1)}  

这是使用queryset的正确方法吗？请帮帮我

多谢各位

Class Sample(forms.ModelForm):  
    class Meta:  
        model = Customer  
        fields = ('name','address',)  
        widgets = {  
            'name' : Select(attrs={'class':'span2'}),  
            'address' : TextInput(attrs={'class':'span4'}),  
             }  

    def __init__(self, *args, **kwargs):
        super(Sample, self).__init__(*args, **kwargs)
        self.fields['name'].queryset = User.objects.filter(type_id=1)
