[web2py] Email as username
Hello list, I have an old application build two years ago and it uses email adress as the username, so you don´t need a different username. Now I´d like to do the same on a new application but I don´t know what to change to do this. Any ideas? Kenneth

Hi Kenneth, remove the 'username' field from the auth_user table. Also see Chapter 8 http://web2py.com/book/default/chapter/08 on custom tables. I think in the past w2p only used email by default.

[web2py] Re: Email as username
Even easier - as I only saw now (always worthwhile to reread the book every so often) (w2p book Ch 8) To start using Auth, you need at least this code in a model file, which is also provided with the web2py welcome application and assumes a db connection object: from gluon.tools import Auth auth = Auth(globals(), db) auth.define_tables(username=False) Set username=True if you want auth to user username for login instead of email.

[web2py] problems with conditional login redirection on on_failed_authorization
on_failed_authorization can be a URL or a function.
I'm think I could use this to achieve conditional login redirection.
A use case would be service calls returning a simple string (or a JSON
or an XML reply to non-validated requests), while still allowing for
regular (non-service requests) to be redirected to a login page.
This is useful for command-line clients (as a recent post argues) and
desktops clients, but also to browser based RIA apps (e.g. Pyjamas
based, Flex,...) where session expiration could lead to wanted
redirections (as is mentioned in
http://www.web2pyslices.com/main/slices/take_slice/48 ).
I would see this as something as simple as:
[in models/db.py]
private_service = Service(globals()) # PRIVATE - for json,
xml, jsonrpc, xmlrpc, amfrpc
public_service = Service(globals())# PUBLIC - for json,
xml, jsonrpc, xmlrpc, amfrpc
...
auth.settings.allow_basic_login = True
def failedAuthHandler():
if request.function == 'private_call':
redirect(URL(f='public_call', args='failed_login'))
else:
redirect(URL(request))
auth.settings.on_failed_authorization = failedAuthHandlerandler
[in controllers/default]
@private_service.jsonrpc
def jsoncount():
return dict(response=response.session_id_name, now=request.now)
@public_service.jsonrpc
def failed_login():
return dict(error='Failed login')
def public_call():
return public_service()
@auth.requires_login()
def private_call():
return private_service()
However, I'm unable to make this code work.
From the command line, if I issue a call with basic auth, with good
credentials, such as:
import jsonrpc
sv =
jsonrpc.ServiceProxy(http://GOOD_USER:GOOD_PASS@127.0.0.1:8080/json_auth_test/default/private_call/jsonrpc;)
sv.jsoncount()
{'now': '2011-01-30 10:31:21', 'response': 'session_id_json_auth_test'}
But bad credentials don't work as expected:
import jsonrpc
sv =
jsonrpc.ServiceProxy(http://GOOD_USER:BAD_PASS@127.0.0.1:8080/json_auth_test/default/private_call/jsonrpc;)
sv.jsoncount()
Traceback (most recent call last):
File stdin, line 1, in module
File

From the browser using an url with or without credentials, for both:
.../default/private_call/jsoncount
.../default/public_call/failed_login
I get:

Am I on the right track?
How could this be achieved?

[web2py] Is Web2py the right choice for me?
I just discovered web2py. I'm wondering if web2py is the right choice for me. Would greatly appreciate any input :) A little background is that I'm a PHP user and a 3D artist. So Python has always been on the top of the to-learn list because it can be used with MAX and MAYA. I recently was given an assignment to create a website for internal use across our LAN network. I'm given a HUGE amount of time so I am using this opportunity to eventually learn Python. Here are some of the specifications of my current assignment and I really would really love to know if web2py provides functionality to make them happen without much fuss. - username and password will be authenticated against Windows Acrive Directory - User group also determines by Active Directory groups. - Everything else will be in MySQL. - A lot of real time drag-and-drop using javascript on the front end. The back end will have to be able to respond to a lot of small requests and update database accordingly. Everything else are generic web stuff so my main concern is only the 4 specs mentioned above. Thank you very much! best regards, Panupat. :)
[web2py] deploying one app to different regions in the world
I have never configured an app like this so I have no idea how this is done. So, any help or pointer is greatly appreciated. Basically, I have an app. If it is hosted in the US, then access in Asia will be slow. And conversely, if it is hosted in Asia, US access will be slow. So, I think the best strategy is to host it both in Asia and the US. Ideally, this will be transparent to users. The simplest configuration I can think of this having 2 domains: domain1.com and domain2.com; each being hosted in US and Asia, respectively. And depending on users' geolocation based on IP addresses, they will be redirected to either domain. Two problems: 1. the appearance of domain1.com and domain2.com is not transparent enough. Is there a better way? 2. maintaining consistency between the 2 databases. Does web2py have support for replications of one app like this? Thanks.

[web2py] Re: Is Web2py the right choice for me?
Welcome Panupat Other users may have more to say on this issue, anyway ... web2py has pluggable login methods. One is gluon/contrib/login_methods/ ldap_auth.py. It contains an example of how to use it. It will allow you to login using Active Directory using LDAP. More complex is the issue with groups. Web2py has its own mechanism for creating groups and checking membership. There is a third party python module to get Active Directory groups and membership (http://timgolden.me.uk/python/ ad_cookbook.html#find_a_user_quick). Somehow you need to put the two together. One option is to extend the class Auth in gluon/tools.py and overload methods add_group, del_group, add_membership, del_membership, has_membership to use the active directory APIs internally. Another option is to use Auth as it is an periodically runs a background script that syncs the web2py database with the ative directory once. I am sorry but if there is a simpler solution I have not seen one. Massimo On Jan 30, 4:25 am, Panupat panup...@gmail.com wrote: I just discovered web2py.

Re: [web2py] Re: Deployment Confusion
AS I said,I know only two host options where you can simply put the files there and everything runs without the need of configuration. ['Google App Engine', 'webfaction'] In other shared hosts you need to follow some deployment instruction: I guess this slice works for godaddy http://www.web2pyslices.com/main/slices/take_slice/76 or if you have a VPS you can use deployment script on /scripts folder, or follow this slices (deppending on your VM setup) http://web2pyslices.com/main/slices/take_slice/110 http://web2pyslices.com/main/slices/take_slice/98 Here in Brazil, we have a shared host (kinghost.com.br) that has 'One Click Install for web2py' in control panel, but I dont know any other.

About 1 I am sure Jonathan has something to day because of the new routing features. About 2. Make sure your database tables have a UUID field.

[web2py] Re: Change in URL args handling
I don't think that they'll be any cleaner or shorter either way. The only way you'll get trailing slashes (if we end up supporting them) is by asking for a URL with empty trailing args. If you don't want trailing slashes, then don't add empty args. Hi, I was mainly thinking of incoming urls being appended with slashes externally and that we could ignore them, but as it has been pointed out, a trailing slash already gives an empty arg, so I suppose we have to keep that. Anyhow, it sounds like your thought process has covered all the bases! :) Thanks. D

The only way you'll get trailing slashes (if we end up supporting them) is by asking for a URL with empty trailing args. If you don't want trailing slashes, then don't add empty args. Hi, I was mainly thinking of incoming urls being appended with slashes externally and that we could ignore them, but as it has been pointed out, a trailing slash already gives an empty arg, so I suppose we have to keep that. Anyhow, it sounds like your thought process has covered all the bases! :) As it stands right now (in the trunk), we're not keeping the empty arg with a trailing slash, mainly because this appears to be a bug in the current implementation (which generally treats empty args as an error).

If you want the values to be evaluated on insert, just do Field(...,default=lambda: f()) What's the difference between using default=lambda: f() and just using default=f (assuming f is defined as a function somewhere)? Is it just that lambda: f() guarantees you get something with type = FunctionType (so, for example, default=lambda: datetime.datetime.now() would work even though type(datetime.datetime.now) is BuiltinFunctionType and not FunctionType), or is there some other reason to prefer the lambda version?

My problem is that if I don't use good credentials in the command line

suggests that the failedAuthHandler I'm using in
auth.settings.on_failed_authorization is not working.
[in models/db.py]
def failedAuthHandler():
if request.function == 'private_call':
redirect(URL(f='failed_login')) # just a regular action
# or alternatively:
redirect(URL(f='public_call', args=['jsonrpc', 'failed_login']))

Since using failed_login as a regular action or as a public_call
makes no difference. is this the correct way to use
auth.settings.on_failed_authorization = function ?

on_failed_authorization can be a URL or a function.
I'm think I could use this to achieve conditional login redirection.
A use case would be service calls returning a simple string (or a JSON
or an XML reply to non-validated requests), while still allowing for
regular (non-service requests) to be redirected to a login page.
This is useful for command-line clients (as a recent post argues) and
desktops clients, but also to browser based RIA apps (e.g. Pyjamas
based, Flex,...) where session expiration could lead to wanted
redirections (as is mentioned in
http://www.web2pyslices.com/main/slices/take_slice/48).
I would see this as something as simple as:
[in models/db.py]
private_service = Service(globals()) # PRIVATE - for json,
xml, jsonrpc, xmlrpc, amfrpc
public_service = Service(globals()) # PUBLIC - for json,
xml, jsonrpc, xmlrpc, amfrpc
...
auth.settings.allow_basic_login = True
def failedAuthHandler():
if request.function == 'private_call':
redirect(URL(f='public_call', args='failed_login'))
else:
redirect(URL(request))
auth.settings.on_failed_authorization = failedAuthHandlerandler
[in controllers/default]
@private_service.jsonrpc
def jsoncount():
return dict(response=response.session_id_name, now=request.now)
@public_service.jsonrpc
def failed_login():
return dict(error='Failed login')
def public_call():
return public_service()
@auth.requires_login()
def private_call():
return private_service()
However, I'm unable to make this code work.
From the command line, if I issue a call with basic auth, with good
credentials, such as:
import jsonrpc
sv =
jsonrpc.ServiceProxy(http://GOOD_USER:GOOD_P...@127.0.0.1:8080/json_auth_test/default/private_call/jsonrpc;)
sv.jsoncount()
{'now': '2011-01-30 10:31:21', 'response': 'session_id_json_auth_test'}
But bad credentials don't work as expected:
import jsonrpc
sv =
jsonrpc.ServiceProxy(http://GOOD_USER:BAD_P...@127.0.0.1:8080/json_auth_test/default/private_call/jsonrpc;)

[web2py] Re: CSV import broken?
Forcing ID's in GAE is a bit harder, and i don't think that web2py has support for that yet. also note that once the database gets to be of significant size the import/export features will have to be written to run as taskqueue tasks on GAE so that they can run for 10 minutes instead of 30 seconds for web based requests. if you are only using GAE consider looking at the GAE bulk import/export tools. they fix ID's, and can run on infinitely large datasets. http://code.google.com/appengine/docs/python/tools/uploadingdata.html

[web2py] Bugfix for CheckboxesWidget
This patch fixes the CheckboxesWidget as a replacement for the
MultipleOptionsWidget in list:reference fields.
list:reference fields use the IS_IN_DB(...,multiple=True) validator. Its
options() method returns possible choices a list of string tuples (key,
label) to be used in HTML option tags and checkboxes. So the widget has to
convert the current values of the reference field to strings as well before
comparing them to the string keys returned by options() - see value=(k in
values).
Without the conversion the checkboxes won't show the current values - there
won't be any check marks.

[web2py] Re: problems with conditional login redirection on on_failed_authorization
sorry this is subtle to spot, but authentication and
authorization is a different thing and it's managed differently
whether you are allowing basic login or not I did an incorrect
assumption making my tests and replying before
if you try with the decorator @auth.requires_membership('aaa') it
should work , but if you are protecting the page with
@auth.requires_login() the default behaviour is to redirect the user
to the login page.
I think that you may want to use
auth.settings.on_failed_authentication instead of
auth.settings.on_failed_authorization
This is because on_failed_authorization is called only when:
- you are allowing only basic login (if the user specified username
and a password and he's not allowed to see a resource, than he's not
authorized)
- if he's yet logged in and he's not allowed to see a resource
(permission, group, etc not matching)
on all the other cases the real thing happening is that the user is
not authenticated (not yet logged in or anonymous), thus the function
on_failed_authorization is not called.
To sum up briefely, on_failed_authentication gets called before
on_failed_authorization in your case.

Re: [web2py] Re: Is Web2py the right choice for me?
Web2py can do all this with a bit of work as shown already. I am curious about your 3d skills as I have been looking for some people to help create a game similar to the old wizardry but using a web-based interface. If you interested in side project like this, drop me a personal email and we can look into it together.

One is gluon/contrib/login_methods/ ldap_auth.py. It contains an example of how to use it. It will allow you to login using Active Directory using LDAP. More complex is the issue with groups. Web2py has its own mechanism for creating groups and checking membership. There is a third party python module to get Active Directory groups and membership (http://timgolden.me.uk/python/ ad_cookbook.html#find_a_user_quick). Somehow you need to put the two together. One option is to extend the class Auth in gluon/tools.py and overload methods add_group, del_group, add_membership, del_membership, has_membership to use the active directory APIs internally. Another option is to use Auth as it is an periodically runs a background script that syncs the web2py database with the ative directory once. I am sorry but if there is a simpler solution I have not seen one. Massimo On Jan 30, 4:25 am, Panupat panup...@gmail.com wrote: I just discovered web2py. I'm wondering if web2py is the right choice for me. Would greatly appreciate any input :) A little background is that I'm a PHP user and a 3D artist. So Python has always been on the top of the to-learn list because it can be used with MAX and MAYA. I recently was given an assignment to create a website for internal use across our LAN network. I'm given a HUGE amount of time so I am using this opportunity to eventually learn Python. Here are some of the specifications of my current assignment and I really would really love to know if web2py provides functionality to make them happen without much fuss. - username and password will be authenticated against Windows Acrive Directory - User group also determines by Active Directory groups. - Everything else will be in MySQL. - A lot of real time drag-and-drop using javascript on the front end. The back end will have to be able to respond to a lot of small requests and update database accordingly. Everything else are generic web stuff so my main concern is only the 4 specs mentioned above. Thank you very much! best regards, Panupat. :)
