如何使Django模型形成Readonly？

Question

我有一个django表单名称"SampleForm".我用来从用户那里获取输入.现在我想使用相同的表单在不同的页面上向用户显示此信息.但表单是可编辑的我想让表单只读.有没有办法让整个形式Readonly？

伪代码(未测试):

class ReadOnlyFormMixin(ModelForm):
    def __init__(self, *args, **kwargs):
        super(ReadOnlyFormMixin, self).__init__(*args, **kwargs)
        for key in self.fields.keys():
            self.fields[key].widget.attrs['readonly'] = True

    def save(self, *args, **kwargs):
        # do not do anything
        pass

class SampleReadOnlyForm(ReadOnlyFormMixin, SampleForm):
    pass
