尝试将其添加到类meta下的表单中：
1 2 3 | def __init__(self, *args, **kwargs): super(StepThreeForm, self).__init__(*args, **kwargs) self.fields['instrucciones'].required = False |
还可以使用此方法向字段添加其他属性：
1 2 3 4 5 | def __init__(self, *args, **kwargs): super(StepThreeForm, self).__init__(*args, **kwargs) self.fields['instrucciones'].required = False self.fields['instrucciones'].label = 'Instrucciones' self.fields['instructions'].help_text = 'Give instructions.' |
您甚至可以使用它来获取表单中的请求：
1 2 3 | def __init__(self, *args, **kwargs): self.request = kwargs.pop('request') super(StepThreeForm, self).__init__(*args, **kwargs) |
但您还必须将请求传递给视图：
1 2 3 4 | def get_form_kwargs(self): kwargs = super(ViewName, self).get_form_kwargs() kwargs['request'] = self.request return kwargs |
