Question

Using Pylons verson 1.0:
Working on the FormDemo example from the Pylons book:

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

My controller has the following functions:

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.'

First I noticed that in the book the author indicates to import redirect_to you executing the following import:

from pylons.controllers.util import redirect_to

This seems to be incorrect, as redirect_to lives in the routes module so I changed it to this:

from routes import redirect_to

everything works fine, no more import error, but when I execute a form submit, i see the following traceback

---

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'

can anyone help me?

Try:

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

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

You might be better off using the current Pylons 1.0 documentation and the QuickWiki tutorial updated for 1.0, among other references on the site.
