在金字塔文档中,Sqlalchemy Dispatch Tutorial使用虚拟数据security.py.我需要使用mysql数据,所以我实现了这样:
我的登录代码
@view_config(route_name='login', renderer='json',permission='view')
def user_login(request):
session = DBSession
username = request.params['username']
password = request.params['password']
sha = hashlib.md5()
sha.update(password)
password = sha.digest().encode('hex')
user = session.query(Users).filter(and_(Users.username==username,Users.password ==password)).count()
if(user != 0):
headers = remember(request, username)
return HTTPFound(location = '/index/',
headers =headers)
else:
print "error"
以上使系统记住将使用的用户名security.py.下面,我使用它来获取用户所在的组.
from .models import (
DBSession,
Users,
)
def groupfinder(userid, request):
session = DBSession()
for instance in session.query(Users).filter(Users.username==userid):
group = 'group:'+instance.group
lsth = {'userid':[group]}
return lsth.get ('userid')
这是使用金字塔授权的最佳方式吗？
我正在关注http://developer.chrome.com/trunk/apps/first_app.html上的Google Chrome网络应用开发,并且网络应用未启动.当我点击页面上的应用程序图标时,它会关闭标签页.我已经从github下载了示例应用程序和插件,但是当我看到控制台时它们也没有工作我得到了这个错误,请不要在chrome:// flags中启用实验API.
Uncaught TypeError: Cannot read property 'onLaunched' of undefined
我已将Chrome浏览器更新为22.0.1229.79版.我的manifest.json文件是
{
"name": "Hello World!",
"description": "My first packaged app.",
"manifest_version": 2,
"version": "0.1",
"app": {
"background": {
"scripts": ["background.js"]
}
},
"icons": {
"16": "calculator-16.png",
"128": "calculator-128.png"
}
}
还有我的background.js文件
chrome.app.runtime.onLaunched.addListener(function() {
chrome.app.window.create('window.html', {
'width': 400,
'height': 500
});
});
有人能指出我哪里出错了吗？
我试图在金字塔框架中使用金字塔烧杯,它只是不工作它创建会话对象但我不能用线访问它们
@view_config(route_name='load_qli', renderer='json')
def load_qli(request):
request.environ['beaker.session']
它给出以下错误
KeyError
KeyError: 'beaker.session'
我的development.ini文件看起来像这样

session.secret = customerssecret
session.cookie_on_exception = true
和init.py这样

sqlalchemy.url = sqlite:///%(here)s/tutorial.db
进入这个
sqlalchemy.url = mysql://root:22password@localhost/alchemy
当我试图跑
../bin/pserve development.ini --reload
它给了我以下错误

<span class="help-block">

我的问题是,password_confirm字段并不总是由金字塔框架呈现,因此它显示下面的错误
chameleon.utils.NameError
NameError: password_confirm
我理解我想使用tal:条件,但我尝试的一切都失败了.有人可以帮助我,我想如何去做一些不会总是在模板中呈现的变量.
我试图使用正则表达式从python中的字符串中删除@tags但是当我尝试这样做时
str = ' you @warui and @madawar '
h = re.search('@\w*',str,re.M|re.I)

它仅输出第一个@tag.
@warui
