flask-admin: заполнить таблицу из SQL-запроса

Question

Я хочу заполнить таблицу из пользовательского запроса SQL. Я не имею ни малейшего представления, как это сделать, отсканировал документы на флеш-админ и гуглил, но ничего не получается.

моя модель БД:

class Attrib(db.Model):
    __tablename__ = 'attribs'
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(255, u'utf8_unicode_ci'), nullable=False, unique=True)
    persistent = db.Column(db.Integer, server_default=db.FetchedValue())
    parent = db.Column(db.String(256, u'utf8_unicode_ci'), server_default=db.FetchedValue())
    ts = db.Column(db.DateTime, nullable=False, server_default=db.FetchedValue())


class Entry(db.Model):
    __tablename__ = 'entries'
    id = db.Column(db.Integer, primary_key=True)
    node_id = db.Column(db.ForeignKey(u'nodes.id', onupdate=u'CASCADE'), nullable=False, index=True)
    attrib_id = db.Column(db.ForeignKey(u'attribs.id', onupdate=u'CASCADE'), nullable=False, index=True)
    value = db.Column(db.String(256, u'utf8_unicode_ci'), nullable=False, index=True)
    ts = db.Column(db.DateTime, nullable=False, server_default=db.FetchedValue())
    attrib = db.relationship(u'Attrib', primaryjoin='Entry.attrib_id == Attrib.id', backref=u'entries')
    node = db.relationship(u'Node', primaryjoin='Entry.node_id == Node.id', backref=u'entries')

    __tablename__ = 'nodes'
    id = db.Column(db.Integer, primary_key=True)

мои просмотры модели:

Все это хорошо работает в том, что я могу выполнять операции CRUD и тому подобное, но я остаюсь абсолютной загадкой, как заполнить "обзорную" таблицу следующим sql. так где / как я могу выполнить этот запрос?
