在挂架中使用重定向时出错

Question

使用Pylons Verson 1.0:使用Pylons书中的FormDemo示例:

http://pylonsbook.com/en/1.1/working-with-forms-and-validators.html

我的控制器具有以下功能:

class FormtestController(BaseController):

    def form(self):
        return render('/simpleform.html')

    def submit(self):
        # Code to perform some action based on the form data
        # ...
        h.redirect_to(controller='formtest', action='result')

    def result(self):
        return 'Your data was successfully submitted.'

首先我注意到在书中作者指示要导入redirect_来执行以下导入:

from pylons.controllers.util import redirect_to

这似乎是不正确的,因为redirect_to存在于routes模块中,因此我将其更改为:

from routes import redirect_to

一切正常,没有更多的导入错误,但当我执行表单提交时,我看到以下回溯

---

h.redirect_to(controller='formtest', action='result')
target = url_for(*args, **kargs)
encoding = config.mapper.encoding
return getattr(self.__shared_state, name)
AttributeError: 'thread._local' object has no attribute 'mapper'

谁能帮我？

Answer 1

尝试:

from pylons import url
from pylons.controllers.util import redirect

# ...
redirect(url(controller='formtest', action='result'))

您可能最好使用当前的Pylons 1.0文档和1.0更新的QuickWiki教程,以及网站上的其他参考资料.
