我正在努力修改cookiecutter Flask应用。
在基于flask-script的manage.py管理模块中,我正在尝试创建一个添加管理员用户的新任务'create_admin'。
@manager.command
def create_admin():
"""Creates the admin user."""
db.session.add(User(
email="ad@min.com",
password="admin",
admin=True,
confirmed=True,
confirmed_on=datetime.datetime.now()
)
)
db.session.commit()
我已将其添加到列表末尾,您可以看到:
manager.add_command('server', Server())
manager.add_command('shell', Shell(make_context=_make_context))
manager.add_command('db', MigrateCommand)
manager.add_command("urls", ShowUrls())
manager.add_command("clean", Clean())
manager.add_command("create_admin", create_admin())
我有一个'用户'模型,如下所示:
class User(UserMixin, SurrogatePK, Model):
__tablename__ = 'users'
username = Column(db.String(80), unique=True, nullable=True)
email = Column(db.String(80), unique=True, nullable=False)
#: The hashed password
password = Column(db.String(128), nullable=True)
created_at = Column(db.DateTime, nullable=False, default=dt.datetime.utcnow)
first_name = Column(db.String(30), nullable=True)
last_name = Column(db.String(30), nullable=True)
active = Column(db.Boolean(), default=False)
is_admin = Column(db.Boolean(), default=False)
confirmed = db.Column(db.Boolean, default=False)
confirmed_on = db.Column(db.DateTime, nullable=True)
def __init__(self, username, email, password=None, **kwargs):
db.Model.__init__(self, username, email=email, **kwargs)
if password:
self.set_password(password)
else:
self.password = None
当我尝试运行新功能时:
$ python manage.py create_admin
Traceback (most recent call last):
File "manage.py", line 57, in <module>
manager.add_command("create_admin", create_admin())
File "manage.py", line 46, in create_admin
confirmed_on=datetime.datetime.now()
TypeError: __init__() takes at least 3 arguments (3 given)
(flask_mini)
我做错了什么?
编辑:
File "C:\envs\r2\myflaskapp\myflaskapp\models\user.py", line 31, in __init__
db.Model.__init__(self, username=username, email=email, **kwargs)
File "c:\envs\virtalenvs\flask_mini\lib\site-packages\sqlalchemy\ext\declarative\base.py", line 525, in _declarative_constructor
(k, cls_.__name__))
TypeError: 'admin' is an invalid keyword argument for User
答案 0 :(得分:1)
您的drawableSize
课程采用User()
位置参数:
username
但你没有通过:
def __init__(self, username, email, password=None, **kwargs):
作为第一个参数传递一个:
db.session.add(User(
email="ad@min.com",
password="admin",
admin=True,
confirmed=True,
confirmed_on=datetime.datetime.now()
)
)
我将db.session.add(User(
'admin',
email="ad@min.com",
password="admin",
is_admin=True,
confirmed=True,
confirmed_on=datetime.datetime.now()
)
)
更正为admin
;您只有一个is_admin
字段。
请注意,您只能将字段值作为关键字参数传递给SQLAlchemy基类:
is_admin
