How to disable field in MongoEngine subdocument in Flask-Admin

February 08, 2018 flask, python

In the documentation there is an information about form_widget_args and form_subdocuments attributes of ModelView class. To do this task they can be used together:

class MyEmbeddedDoc(DynamicEmbeddedDocument):
    created = DateTimeField(default=datetime.utcnow)


class MyDoc(DynamicDocument):
    data = EmbeddedDocumentField(MyEmbeddedDoc)


class MyDocView(ModelView):
    form_subdocuments = {
        'data': {
            'form_widget_args': {
                'created': {'disabled': True}
            }
        }
    }
