kha*_*mel 12 python flask flask-security blinker
我正在尝试使用user_registered信号,以便在用户使用flask-security注册时为用户设置默认角色,如以下链接所示:在Flask Security中设置默认角色
在我的搜索中,我可以看到在烧瓶安全性中已经解决了这个问题:没有从烧瓶安全性,Fix - user_registered信号问题获得信号
我已尝试以下方法来证明处理程序是否收到信号而没有任何运气:
@user_registered.connect_via(app)
def user_registered_sighandler(sender, **extra):
print("print-user_registered_sighandler:", extra)
然而,即使用户注册并且应该发送信号,也不会被调用.
如果它有助于我设置flask-security配置如下:
app.config['SECURITY_REGISTERABLE'] = True
app.config['SECURITY_CONFIRMABLE'] = False
app.config['SECURITY_SEND_REGISTER_EMAIL'] = False
app.config['SECURITY_CHANGEABLE'] = True
app.config['SECURITY_SEND_PASSWORD_CHANGE_EMAIL'] = False
来自Flask-Login和Flask-Principal的信号正在为我工作,因为我设法确认以下代码片段在发送信号时成功打印:
@user_logged_out.connect_via(app)
def on_user_logged_out(sender, user):
print('USER LOG OUT: made it in',user)
@identity_changed.connect_via(app)
def identity_changed_ok(sender,identity):
print('Identity changed:',identity)
对于我的设置,我使用python 3.3(anaconda)并使用以下内容:Flask == 0.10.1,flask-login == 0.2.11,flask-principal == 0.4.0,flask-security == 1.7.4,信号灯== 1.3.看了瓶子登录和烧瓶安全的信号,我不知道为什么烧瓶安全信号不起作用.
编辑:
如果我print(user_registered.receivers)在我的应用程序中添加路线,它将显示我有一个接收器:{139923381372400: <function user_registered_sighandler at 0x7f42737145f0>}.如果我把这个相同的print语句放在flask-security的registerable.py之前,user_registered.send(app._get_current_object(),user=user, confirm_token=token)那么它就没有列出接收器:{}
EDIT2:
问题似乎与使用python 3.3有关.我创建了一个python 2.7环境,user_registered代码按预期工作.
完整代码重现:
from flask import Flask,render_template
from playhouse.flask_utils import FlaskDB
import os
from flask.ext.security import Security, PeeweeUserDatastore
from flask.ext.security.signals import user_registered
from flask.ext.login import user_logged_out

app = Flask(__name__)
app.config['ADMIN_PASSWORD']='secret'

app.config['DATABASE']='sqliteext:///%s' % os.path.join(app.config['APP_DIR'], 'blog.db')
app.config['SECRET_KEY'] = 'shhh, secret!'
app.config['SECURITY_REGISTERABLE'] = True
app.config['SECURITY_CONFIRMABLE'] = False
app.config['SECURITY_SEND_REGISTER_EMAIL'] = False
flask_db = FlaskDB()
flask_db.init_app(app)
database = flask_db.database
class BaseModel(Model):
class Meta:
database=flask_db.database
class User(BaseModel, UserMixin):
email=CharField()
password=CharField()
active = BooleanField(default=True)
confirmed_at = DateTimeField(null=True)
def is_active(self):
return True
def is_anonymous(self):
return False
def is_authenticated(self):
return True
class Role(BaseModel, RoleMixin):
name = CharField(unique=True)
description = TextField(null=True)
class UserRoles(BaseModel):
user = ForeignKeyField(User, related_name='roles')
role = ForeignKeyField(Role, related_name='users')
name = property(lambda self: self.role.name)
description = property(lambda self: self.role.description)
user_datastore = PeeweeUserDatastore(database, User, Role, UserRoles)
security = Security(app, user_datastore)
@user_registered.connect_via(app)
def user_registered_sighandler(sender,**extra):
print("print-user_registered_sighandler")
@user_logged_out.connect_via(app)
def on_user_logged_out(sender, user):
print('USER LOG OUT: made it in',user)
@app.route('/')
def index():
print(user_registered.receivers)
return render_template('base.html')
database.create_tables([User,Role,UserRoles], safe=True)
app.run(debug=True)
base.html模板:
<!doctype html>
<html>
<head>
<title>Blog</title>
</head>
<body>
<ul>
{% if current_user.is_authenticated() %}
<li><a href="{{ url_for('security.logout',next='/') }}">Log out</a></li>
<li><a href="{{ url_for('security.register') }}">Register</a></li>
{% else %}
<li><a href="{{ url_for('security.login',next='/') }}">Login</a></li>
<li><a href="{{ url_for('security.register') }}">Register</a></li>
{% endif %}
{% block extra_header %}{% endblock %}
</ul>
</body>
</html>
如果导入user_registered更改为以下内容：
from flask.ext.security import user_registered
那么信号将按 python 3.3 中的预期工作，并user_registered_sighandler在用户注册时调用该函数。
该user_registered信号在文件中导入__init__.py以确保烧瓶安全，因此它也可以在包的顶层使用。
