The validate and authenticate_form decorators don't seem to play nice together. This is my template:
<html>
<title>Test</title>
<body>
${h.secure_form('/meow/do_post')}
<input type="text" name="dummy">
<form:error name="dummy"><br>
<input type="submit" name="doit" value="Do It">
${h.end_form()}
</body>
</html>
And this is the controller:
开发者_如何学JAVAimport logging
from pylons import request, response, session, tmpl_context as c, url
from pylons.controllers.util import abort, redirect
from ocust.lib.base import BaseController, render
import formencode
import formencode.validators
from formencode import htmlfill
from pylons.decorators import validate
from pylons.decorators.secure import authenticate_form
class MeowForm(formencode.Schema):
allow_extra_fields = True
dummy = formencode.validators.NotEmpty()
class MeowController(BaseController):
def index(self):
return render('/index.mako')
@authenticate_form
@validate(schema=MeowForm(), form='index')
def do_post(self):
return 'posted OK'
If validation fails, the form is re-rendered using htmlfill.render by the @validate decorator, but this strips out the authentication token, so a 403 CSRF detected error is shown the next time the form is submitted.
The authentication token seems to be stripped because @authenticate_form deletes the authentication token from request.POST.
If this is used instead:
@validate(schema=MeowForm(), form='index', force_defaults=False)
it works fine. Is there anything bad that can happen if force_defaults is set to False? The docs for htmlfill seem to recommend it be set to True when the defaults "are the result of a form submission".
@validate(schema=MeowForm(), form='index')
@authenticate_form
def do_post(self):
You need to change order of decorators, authenticate decorator must be last
