我在pymysql和mysql中使用flask sqlachemy
我正在尝试使用flask_fixture将数据插入数据库时测试我的应用程序。
我想这去了数据库，但它返回一个错误
'Department' object has no attribute 'translate'
所以我不明白为什么会抛出该错误
from flask_login import (UserMixin, current_user, LoginManager)
from flask_dance.consumer.storage.sqla import OAuthConsumerMixin
from werkzeug.security import generate_password_hash, check_password_hash
from . import db
class Department(db.Model):
# this model handles everything to do with the department information
__tablename__ = 'departments'
id = db.Column(db.Integer, primary_key = True)
name = db.Column(db.String(64), nullable = False)
description = db.Column(db.String(300), nullable = False) ```
Here is the file I want to insert using `flask_fixtures`
[
{
"table": "departments",
"records": [{
"id": 8,"name": "Kinds","description": "all goods about kids"},
{"id": 9,"name": "panties", "description": "this is a women section"}
]
}
]
这里是抛出错误
