我试图在一个比Flask-Sec的文档中给出的示例更有条理的应用程序中使用Flask-Security。
使用格式：
\proj
__init.py__
views.py
models.py
config.py
我在models.py中设置了Quickstart代码。据我所知，这是一个非常精确的副本。
from proj import db
##################################### USERS AND ROLES ############################################
roles_users = db.Table('roles_users',
db.Column('user_id', db.Integer(), db.ForeignKey('user.id')),
db.Column('role_id', db.Integer(), db.ForeignKey('role.id')))
class Role(db.Model, RoleMixin):
id = db.Column(db.Integer(), primary_key=True)
name = db.Column(db.String(80), unique=True)
description = db.Column(db.String(250))
class User(db.Model, UserMixin):
id = db.Column(db.Integer(), primary_key=True)
email = db.Column(db.String(255), unique=True)
password = db.Column(db.String(255))
active = db.Column(db.Boolean())
confirmed_at = db.Column(db.DateTime())
roles = db.relationship('Role', secondary=roles_users, backref=db.backref('users'), lazy="dynamic")
#Setup Flask security
user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)
然而，当所有的事情都说完了，我得到了这个追溯：

答案 0 :(得分：0)
所以它说“没有这样的表”。您是否检查过您是否真的拥有该表并创建了数据库？
这样写：“pip install flask-migrate”
然后复制粘贴此脚本：
from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy
from flask.ext.script import Manager
from flask.ext.migrate import Migrate, MigrateCommand
from app.models import *
from flask.ext.security import UserMixin, RoleMixin
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///app.db'
db = SQLAlchemy(app)
migrate = Migrate(app, db)
manager = Manager(app)
manager.add_command('db', MigrateCommand)
roles_users = db.Table('roles_users',
db.Column('user_id', db.Integer(), db.ForeignKey('users.id')),
db.Column('role_id', db.Integer(), db.ForeignKey('roles.id')))
class Role(db.Model, RoleMixin):
__tablename__ = "roles"
id = db.Column(db.Integer(), primary_key=True)
name = db.Column(db.String(80), unique=True)
description = db.Column(db.String(255))
class User(db.Model, UserMixin):
__tablename__ = "users"
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(255), unique=True)
password = db.Column(db.String(120))
active = db.Column(db.Boolean())
last_login_at = db.Column(db.DateTime())
current_login_at = db.Column(db.DateTime())
last_login_ip = db.Column(db.String(100))
confirmed_at = db.Column(db.DateTime())
current_login_ip = db.Column(db.String(100))
login_count = db.Column(db.Integer)
roles = db.relationship('Role', secondary=roles_users,
backref=db.backref('users', lazy='dynamic'))
connections = db.relationship('Connection',
backref=db.backref('user', lazy='joined'), cascade="all")
def __str__(self):
return '<User id=%s email=%s>' % (self.id, self.email)
class Connection(db.Model):
__tablename__ = "connections"
id = db.Column(db.Integer, primary_key=True)
user_id = db.Column(db.Integer, db.ForeignKey('users.id'))
provider_id = db.Column(db.String(255))
provider_user_id = db.Column(db.String(255))
access_token = db.Column(db.String(255))
secret = db.Column(db.String(255))
display_name = db.Column(db.String(255))
full_name = db.Column(db.String(255))
profile_url = db.Column(db.String(512))
image_url = db.Column(db.String(512))
rank = db.Column(db.Integer)
if __name__ == '__main__':
manager.run()
之后写：
python db_migrate db init
python db_migrate db migrate
python db_migrate db upgrade
然后使用“nano app.db”检查它，您应该看到创建的数据库和表格。
