pylons.config and development.ini
Hello,
In file: envinronment.py,
def load_environment:
- I set up a few configuration variables like
config['my_var1'] = u'something'
config['my_var2'] = u'something2'
# I want that every var has been unicode type.
Last time I moved a few above variables to development.ini, but now I
have a little problem with encoding
because I have to every variable that become from ini to decode('utf-8').
There exists some way to automatically convert or load variables from
ini as unicode?
Best Regards,
Tomasz Narloch

My example:

[...]
try:
String(not_empty=True, min=2).to_python(value['company']) #
raise KeyError
except formencode.Invalid, e:
errors.update({'company': unicode(e)})
[...]
class UserFormUpdate(formencode.Schema):
allow_extra_fields = True
individual = StringBool(if_missing=False, if_empty=False)
[...]
company = String(max=128, if_missing=None, strip=True), # -- The
error is a comma!!!, but I can create pyc and use it
[...]
chained_validators = [GoodUserForm()]
This file can be compile, but it is not works as expected.

Re: problem with routes rule
c pisze:
hello everyone!
i'm new to pylons and routes and i'd encountered a problem trying to
configure routes to my needs.
i'd like to have admin panel section in my site (with subsections like
overall settings, gallery settings etc.), and wanted an urls too look
like that:
www.example.com/panel/overall/save - that would trigger action save of
controller panel_gallery
I use that configuration:
map.connect('/panel/overall/{action}/{id}',
controller='panel/overall', action='index', id=None, _minimize=True)
www.example.com/panel/gallery/add - that would trigger action add of
controller panel_gallery
you maybe add also:
map.connect('/panel/{action}', controller='panel_auth', action='index',
_minimize=True)
for
www.example.com/panel
And create controller command:
$ paster controller panel/gallery
List of files:
controllers/panel_auth.py
controllers/panel/gallery.py
after reading routes manual I wasn't able to come up with a solution
i'd be grateful for any suggestions

I think the problem is in @authenticate_form.
This function/decorator remove request.POST['_authentication_token'].
Htmlfill doesn't have this value and set empty string.
Ex:
html = render('/my_template.mako') # - _authentication_token is set
return htmlfill.render(html, defaults=request.POST, errors=errors,
force_defaults=False) # - without force_defaults=False
_authentication_token will be cleared.

Re: Routes and Controllers

One more thought...
Would it be necessary to add an entry to Routes for each controller?
Or, can one (or just a few) entries be added which contain dynamic
parts?

In my project, there are a number of controllers (and corresponding

here are the locations of three controllers:
/myproject/controllers/ai/q01.py
/myproject/controllers/ai/q23.py
/myproject/controllers/ai/w02.py
How should Routes be set up so that the following URL is mapped to the

http://www.somedomain.com/ai/q01
Would the following be correct (assuming it's placed higher in the

map.connect('/ai/{controller}/{action}')
Maybe it is not the best routes but it's works:
map.connect('/error/{action}', controller='error')
map.connect('/error/{action}/{id}', controller='error')

map.connect('/admin/page/{action}/{id}',

Redirect with additional headers for ajax

Sometimes I need to redirect page from example: index to index2
The problem is when I get index with request.is_xhr == True and have to
redirect to index 2.
In next page request.is_xhr == False.
jQuery do not add 'X-Requested-With': XMLHttpRequest' to redirected page.
Is some possibility to add headers with XMLHttpRequest to method of
controller:
[...]
# add header
return redirect_to('page/index2')
and then would be works when I check request.is_xhr?

Re: Pylons with gzip compression?

Maybe it is? I know that above example from book works but compressing the same static css and js each request is not that I need. How can I add cache for this gziped file?

Re: sqlalchemy objects in beaker cache

Hi,
Is it safe to cache objects getting from sqlalchemy session query in
beaker cache?
I was done that but in that way I loose connection with sqlalchemy
(Session) so
from ... import User
from ... import t_user
mapper(User, t_user,
properties={
'roleList': relation(Role, backref='userList')})
us = User()
#us - to backer_cache
now if you want us.roleList you get error
and if you change
us.username = 'other_name'
Session.commit()
then it not affected any change
Above is only my experience.

This is little not secure maybe so create in config variable:
routes = dict(panel='/panel/login', admin='/admin/login')
and put:
input type=hidden
name=if_error_back_to value=panel /
in form and check if request.POST['if_error_back_to'] in routes then
redirect to routes[request.POST['if_error_back_to']]
this is more flexible and secure.

Hello, Tomasz,

Authentication ;-)
But how can you check referer for prefix:
referer: /order/index2 = translate to /order/login
referer: /admin/ = translate to /admin/login
referer: /panel/= translate to /panel/login
It could be something like that:
def loginurl_func(environ):
if environ['beaker.session']['referer'].endswith('/order/index2'):
return '/order/login'
elif environ['beaker.session']['referer'].endswith('/admin'):
return '/admin/login'
else:
return '/panel/login'
I'm not sure how much safe is to use endswith. Maybe it is more
reasonable to use some routes method to parse referer.
2) will be option to set:
referer /order/index2 = translate to
/order/other_method_name_for_login # not default name for method to login
referer /admin/= transate to /admin/login # as usual
It's up to you to control options. You have function (loginurlfunc)
and you can do anything you want with that.
That is good for me.
I always set referer to relative link so I can
if environ['beaker.session']['referer'] == '/order/index2':
but it's not matter.
When you publish new version, today or tomorrow or ...?
Thanks for your time

Re: Problem with Authkit 0.4.2 and Pylons 0.9.7rc4 on Apache2 and mod_wsgi 2.3
I check your authauth middleware. Maybe I will like it. That I need. For users I need only authenticated but for admins I need authorized also. User can buy some products from shop or go to own panel (customers area panel) but admins do not only (admin area). Admins - table admin in database [authkit at now] - I have plan to change this to your authauth middleware. Users - table user in database [actually I have written my own authenticated function, pure but working, without middleware] My question: 1. I need download authform-middleware and authorize-middleware or only authorize-middleware? 2. At now I can't use easy_install so where is the best place for this libs? Maybe on pylons .../lib/authorize-middleware/ and .../lib/authform-middleware/ at the moment?

authauth middleware details
I start to learn authauth
1) I have one login form for client to panel
and second if someone want to buy something then go step by step and
next can login or create new account (different url, design)
There is a variable:
authform.loginurl= /panel/login
How sholud I change it if I want different authform.loginurl for one page?
Code from authform.py:
[...]
def process(self, environ, start_response):
baseurl = self.baseurl or construct_url(environ,
with_query_string=False, with_path_info=False)
params = dict(paste.request.parse_formvars(environ))
session = environ[self.session_middleware]
authenticated, data = self.is_authenticated(environ,
params['username'], params['password'])
if authenticated:
session['REMOTE_USER'] = params['username']
if data:
session['x-wsgiorg.user_data'] = data
if 'referer' in session:
redirect_url = session.pop('referer')
else:
redirect_url = self.baseurl + self.loggedin_url
start_response('301 Redirect', [('Content-type',
'text/html'), ('Location', redirect_url)])
return []
else:
session['x-wsgiorg.auth_error'] = data
+if 'loginurl' in session:
+ loginurl = session.pop('loginurl')
+else:
+ loginurl = self.loginurl
+
+start_response('301 Redirect', [('Content-type', 'text/html'),
('Location', loginurl)])
-start_response('301 Redirect', [('Content-type', 'text/html'),
('Location', self.loginurl)])
return []
[...]
2) Where can I put @authenticate_form?

1) Wrong place for middleware. Add it under # CUSTOM MIDDLEWARE HERE
line. Much better place. At least immediately after if
asbool(full_stack): line.
It's done. I place it after # CUSTOM MIDDLEWARE HERE
2) Next problem is that you set full_stack to false in deployment.ini.
Why? Actually it is the biggest problem.
Okey, it's done
3) You shoud disable debug in deployment.ini. There is no reason to
run application in debug mode under WSGI.
It's misunderstanding, I have had set debug = false on deployment.ini
HTH.
Result:
Instead Apache 404 error now I get pylons 404 error on page.
The same error exist in logs.
Error come from mod_wsgi.c:
while ((item = PyIter_Next(iterator))) {
if (!PyString_Check(item)) {
PyErr_Format(PyExc_TypeError, sequence of string
values expected, value of type
%.200s
found, item-ob_type-tp_name);
Py_DECREF(item);
break;
}
but I don't understand way.
As well, you might find my authauth middlewares more usable for you
http://trac.sandbox.lt/auth/wiki/AuthFormMiddleware,
http://trac.sandbox.lt/auth/wiki/AuthorizeMiddleware.
Maybe I check it.
That's different
from AuthKit a little bit but at least I will be able both answer and
fix your problems if you will have them.
Thanks,
Best Regards
