Question

我跟着this Tutorial测试我的MySQL for Web.py Setup。

由于教程没有完整的源代码，我在这里发帖：

import web
import MySQLdb

web.config.debug = False

urls = (
  '/login', 'Login',
  '/reset', 'Reset',
)
app = web.application(urls, locals())
db = web.database(dbn='mysql', db='dbname', user='user', pw='password')

store = web.session.DiskStore('sessions')
session = web.session.Session(app, store,
                              initializer={'login': 0, 'privilege': 0})

def logged():
        if session.login==1:
            return True
        else:
            return False
def create_render(privilege):
    if logged():
        if privilege == 0:
            render = web.template.render('/Users/me/Desktop/cpage/Templates/reader')
        elif privilege == 1:
            render = web.template.render('/Users/me/Desktop/cpage/Templates/user')
        elif privilege == 2:
            render = web.template.render('/Users/me/Desktop/cpage/Templates/admin')
        else:
            render = web.template.render('/Users/me/Desktop/cpage/Templates/communs')
    else:
        render = web.template.render('/Users/me/Desktop/cpage/Templates/login')
    return render
class Login:
    def GET(self):
        if logged():
            render = create_render(session.privilege)
            return '%s' % render.login_double()
        else:
            render = create_render(session.privilege)
            return '%s' % render.login()
    def POST(self):
        name, passwd = web.input().name, web.input().passwd
        ident = db.select('example_users', where='name=$name', vars=locals())[0]
        try:
            if hashlib.sha1("sAlT754-"+passwd).hexdigest() == ident['pass']:
                session.login = 1
                session.privilege = ident['privilege']
                render = create_render(session.privilege)
                return render.login_ok()
            else:
                session.login = 0
                session.privilege = 0
                render = create_render(session.privilege)
                return render.login_error()
        except:
            session.login = 0
            session.privilege = 0
            render = create_render(session.privilege)
            return render.login_error()
class Reset:
    def GET(self):
        session.login = 0
        session.kill()
        render = create_render(session.privilege)
        return render.logout()

if __name__ == "__main__":
    app.run()

桌面上的目录cpage包含如下：

DBTest.py模板login.html会话

在模板中还有另一个login.html，只是为了确保它存在，因为我遇到的问题是：服务器能够从终端启动（我正在运行MacOSX Mavericks）但无论何时我输入localhost：port / login，它都会崩溃：

http://0.0.0.0:1234/

    raise AttributeError, "No template named " + name
AttributeError: No template named login

Answer 1

好吧，我自己想出来，可能是学习东西的最好方法。无论哪种方式，我都想向世界提供答案。

首先，教程中的代码看起来有点不同，所以post helped me a lot.

使用此代码后（或更好：合并）我遇到了同样的问题。

我最后不得不重新组织我的文件夹结构。将layout.html添加到Templates文件夹可以解决问题。使用正确的目录路径也很重要。

找不到Web.py模板
