class DeployApplyForm(ModelForm):
    	//project = forms.ChoiceField(choices=Project.objects.filter(prj_mgr='').value_list('id','name'))
    	//使用上述代码会报can't assign must be a instance，所以要使用下行代码
        project = forms.ModelChoiceField(queryset=Project.objects.filter(prj_mgr=''))
        bgn_time = forms.DateTimeField(initial=datetime.datetime.now().strftime("%Y-%m-%dT%H:%M:%S"), label=u'开始',
                                       input_formats=['%Y-%m-%dT%H:%M:%S'], widget=forms.DateTimeInput(
                attrs={'type': 'datetime-local', 'emptyTips': u'请选择时间', 'step': '1'}))
        end_time = forms.DateTimeField(initial=datetime.datetime.now().strftime("%Y-%m-%dT%H:%M:%S"), label=u'结束',
                                       input_formats=['%Y-%m-%dT%H:%M:%S'], widget=forms.DateTimeInput(
                attrs={'type': 'datetime-local', 'emptyTips': u'请选择时间', 'step': '1'}))
    
        class Meta:
            model = DeployApply
            fields = '__all__'
