我有一个Django表单名称 SampleForm。我用来接受用户输入的内容。现在，我想使用相同的表单在不同页面上向用户显示此信息。但是表格是可编辑的，我想使表格只读。有什么方法可以使整个表单变为只读状态？

推荐答案

伪代码（未经测试）：

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
