嘗試在數(shù)據(jù)庫中為我的表創(chuàng)建此模型，但是在查看表時遇到此關(guān)鍵錯誤，然后又出現(xiàn)此錯誤，我懷疑這是將數(shù)據(jù)添加到表中的問題的鏈接，對您有很大幫助贊賞。我還在視圖模塊中創(chuàng)建了一個視圖，但是它只是模型之間的簡單連接，我列出了字段，我將包含appbuilder所需的視圖，views.py：class PView(ModelView):    datamodel = SQLAInterface(Profile)    list_columns = ['id', 'name', 'properties']appbuilder.add_view(PView, "X", icon="fa-envelope", category="X")models.py：class Profile(Model):    __tablename__ = 'profile'    id = Column(Integer, primary_key=True)    name = Column(String(100), nullable=False)    properties = Column(JSONB, nullable=True)    def __repr__(self):        return self.name追溯：Traceback (most recent call last):  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask/app.py", line 1982, in wsgi_app    response = self.full_dispatch_request()  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask/app.py", line 1614, in full_dispatch_request    rv = self.handle_user_exception(e)  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask/app.py", line 1517, in handle_user_exception    reraise(exc_type, exc_value, tb)  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask/_compat.py", line 33, in reraise    raise value  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask/app.py", line 1612, in full_dispatch_request    rv = self.dispatch_request()  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask/app.py", line 1598, in dispatch_request    return self.view_functions[rule.endpoint](**req.view_args)  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask_appbuilder/security/decorators.py", line 26, in wraps    return f(self, *args, **kwargs)  File "/Users/adam/myapp/venv/lib/python3.6/site-packages/flask_appbuilder/views.py", line 478, in list    widgets=widgets)
