如何使 Django 模型成为只读形式？

Question

我有一个 django 表单名称 "SampleForm"。我用它来接受用户的输入。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。但是表格是可编辑的我想让表格只读。有什么方法可以使整个表单只读吗？

Answer 1

class SampleForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(SampleForm, self).__init__(*args, **kwargs)
        instance = getattr(self, 'instance', None)
        if instance and instance.pk:
            for field in self.fields.keys():
                self.fields[field].widget.attrs['readonly'] = True

只要有一个实例可用于表单，这就应该使整个表单只读。

Answer 2

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

Answer 3

工作代码

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