Flask 如何通过 appbuilder 将字段设置为只读

Question

我用什么替换文本字段，我知道我用我试图设为只读的字段替换了 field2。我得到：

NameError: name *'TextField' is not defined*

Define/override只读字段像这样，先定义一个新的只读字段：

from flask_appbuilder.fieldwidgets import BS3TextFieldWidget

class BS3TextFieldROWidget(BS3TextFieldWidget):
    def __call__(self, field, **kwargs):
        kwargs['readonly'] = 'true'
        return super(BS3TextFieldROWidget, self).__call__(field, 
**kwargs)

接下来使用您的新小部件覆盖您的字段：

class ExampleView(ModelView):
    datamodel = SQLAInterface(ExampleModel)
    edit_form_extra_fields = {'field2': TextField('field2',
                                widget=BS3TextFieldROWidget())}

确保在文件顶部声明了它
