[web2py] Re: Front end framework

[Massimo Di Pierro]

I do not know how much different 4 and 5 are. Only the names of the classes 
in the forms may be an issue. I would recommend you try it with BS 5 and if 
you run into any issue it may be possible to address it with a new adapter 
or, maybe easier, a few lines of JS.

I think it will always be experimental. I do not want to take any 
responsibility for breaking your local installation. :-)

[web2py] web2py 2.26.1 released

[Massimo Di Pierro]

Changelog:
- adds support of python up to version 3.11
- fixes a bug with serialization of headers introduced in version 2.25.1
- improves handling of unstable db connections in the scheduler

I remind you that py4web has been out for 5 years now as successor of 
web2py.
It has the same template language and dal as web2py but it is a lot faster.
It has a better grid, form handling, and auth integrations.

Massimo

[web2py] web2py 2.25.1

[Massimo Di Pierro]

Hello everybody,

A new version of web2py, 2.25.1, is out. 

It contains some bug fixes, #2468 #2468 #2236, http headers sanitization, 
and fixes this vulenarbility https://jvn.jp/en/jp/JVN80476432/ (to be 
published soon).

The vulnerabily does not affect most users. It is only in the optional 
MessageBoxHandler for logging when using Tkinter. I do know think anybody 
is was using it.

I am reviewing some old PRs and I may have another version out today 
including those fixes as well. Sorry I have been slow but as you know, I am 
spending more time on py4web than web2py these days. 

Massimo

 Good Morning,

 We are using IIS 10 with web2py 2.23.0.

 When I try to pack the welcome application (or any other), using 
 pack_all I get a 403 error.
 When I try to pack the welcome application (or any other), using 
 pack_custom, it first displays the file selector and when I click on 
 download as .w2p I get a 403 error.

 This seems to be related to the open_redirect changes.  I tried 
 putting the 403 error related code from the admin\default.py 
 controller in 
 comment, but it still is giving the error.  

 Kind Regards,
 David

[web2py] web2py 2.23.0 released

[Massimo Di Pierro]

Hello Everybody,

My apologies for not being as engaged in this group as I used to be.

web2py 2.23.0 was released.

It includes:
- DKIM support to emails
- More configuration options for 2-factor authentication
- Fixed an open redirect vulnerability
- Some bugs fixes.

Thanks everybody who contributed, especially Leonel.

As you noticed the pace of changes in web2py is very slow. Once again I 
recommend that you take a look at py4web, also based on pydal and the same 
template language and helpers as web2py. Yet it is much faster and designed 
from scratch to work with python 3.

Massimo

[web2py] Re: deploy web2py with gunicorn, Nginx y HTTPS

[Massimo Di Pierro]

Gunicorn creates processes, not threads so if you have multiple CPUs is 
takes advantage of them. Threads in python do not work as well because of 
the GIL and some times make things worse.

[web2py] Re: Pillow not imported by web2py-win

[Massimo Di Pierro]

can you try "pip install pillow" instead of putting it in 
C:\Users\Dave\web2py_win\web2py_win_2.21.1_py27\web2py\site-packages 
Not all packages like to be there and it can create problems.

[web2py] Re: wev2py 2.22.1 is out

[Massimo Di Pierro]

I am very confused by this. I cannot find any change that could cause this 
change of behavior. Let me summarize to make sure I am understanding.

You observed a change of behavior between 2.21.1 and 2.22 1.
The change of behavior only manifests when you declare a default app in 
routers.py
The change of behavior consists of the fact that, if you upload a file 
using a form, the link to download the file does not work.
You can confirm that the file is there and the link works if no default app 
in routers is provided.

Is this all correct? If yes. I will debug more. If you could provide a 
minimalist app to reproduce it would save me some time.

Massimo

[web2py] Re: belongs DAL syntax to search word contains in list:reference type Field

[Massimo Di Pierro]

this should work:

nested_select = 
db(db.address.address.contains('boulevard'))._select(db.address.id)
rows = db(db.customer.address.belongs(nested_select) ).select()

Notice the _select instead of select makes it a nested select.
Without _ it would give the same result with two explicit selects.

[web2py] Re: sqlhtml changes for sqlform.factory, not nice, 2.15.4 versus 2.18.5

[Massimo Di Pierro]

Looking at latest version 2.21. The change you mention is only for create 
forms, not edit forms. It basically say if a field is readable and not 
writable and has not value, it should not be displayed. It seems the 
correct behavior to me. Maybe in 1.18 the same logic was incorrectly 
applied to edit fors as well? Do not remember. Please try the latest.

 we are using sqlform.factory a lot, but the way fields are shown/behave 
 was changed from
 2.15.4
 fields = [f.name for f in table if  (ignore_rw or f.writable or 
 f.readable) 
 and (readonly or not f.compute)]
 to
 2.18.5
 fields = [f.name for f in table if (ignore_rw or f.writable or 
 (f.readable and f.default)) and not f.compute]

 so in 2.15.4 it was no problem to have an edit form with fields like
 readable=True, writable=False, default=""
 this field having an empty string was shown disabled, great as expected.

 in 2.18.5
 this field will not be shown anymore, we need to set default=" " like 
 this, which is
 not very useful.

 Is this a bug or feature, or is there a NEW common way to have empty 
 readonly fields in an
 edit form

 Many thanks for any help!

[web2py] Re: this not runs . Field('materials', 'list:string','reference malzemeler')

[Massimo Di Pierro]

Hello Cassio,

the Field constructor takes a name and a type. The type can be 
"list:reference malzemeler" (assuming you have a table malzemler). Also if 
you want the value to display something other than the id of a referenced 
record, you have to specify a record format for the referenced table. In 
your case for example db.define_table("malzemler", Field("name"), 
format="%(name)s").

If you want dropdowns in multi-lists you may want to consider using 
requires=IS_IN_DB(db, table.id, table.namefield, multiple=True) and use 
something like 
http://www.web2pyslices.com/slice/show/1395/jquery-multi-select-widget

Notice that all of this is very old. If you need a complex interface I 
would highly recommend using Vue.js and create your own UI and use py4web 
for backend api. That will work much better and be more customizable.

Massimo

[web2py] Re: Guidelines for choosing web2py or py4web

[Massimo Di Pierro]

I started both projects so I have an opinion on this topic. :-)

Use py4web.

web2py started in 2007 and it is now 14 years old. We learned a lot from it 
and py4web was thought of a successor.

py4web and web2py share:
- the same DAL
- the same validators
- the same template language (but a faster implementation)
- the same default multi-threaded web server (rocket3) but both work with 
any.
- almost equivalent helpers DIV, SPAN, etc (but simpler, faster, less 
gotcha, must be imported)
- similar web based IDE
- similar internationalization system (T) but better pluralization 
capabilities
- similar SQLFORM/Grid API called Form/Grid but more customizable and 
faster.
- both can run multiple apps behind one framework instance.

py4web is better than web2py because:
- it is at least 10x faster
- it is designed for Python 3
- you can "pip install py4web" and that is all you need to do
- no gotchas when using third party libraries
- it does not eval code at every request but uses normal python modules 
(every app is a module)
- it uses a routing syntax similar to bottle/flask
- it has an extensible Auth mechanism.
- it has better documentation (uses read-the-docs/sphinx)
- it has a much smaller code base and it is more modular

py4web lacks (when comparing to web2py):
- @auth.requires_login() decorators because we use a different mechanism 
@action.uses(auth.user)
- auth groups and permission because we handle groups and permissions with 
DAL Tags on users.
- CAS (because we have not finished implementing it) but we have better 
Oauth2 support, including Google, Facebook, and Ockta.

Gotchas:
- there is not request.args and request is the bottlepy/ombott Request 
object.
- auth.user is now called auth.current_user (auth.user is a Fixture) and 
this confuses people a bit.
- the web IDE and appadmin equivalent logic is more spartan and we are 
still improving it.

web2py is very stable has has not been touched in months.
py4web is still evolving we make commits almost every day.
I have ported my old apps to py4web without too much trouble.

Massimo

Example of py4web app:

from py4web import DAL, Field, action
from py4web.utils.form import Form

db = DAL("sqlite::storage.db")
db.define_table("thing", Field("name"))

@action("thing", method=["GET", "POST"])   # create form with postbacks
@action("thing/", method["GET", "POST"])  # edit form with postbacks
@action.uses(db, "index_template.html")  # specify the template file
def thing(id=None):
   form = Form(db.thing, id)   # same as SQLFORM(db.thing, 
request.args(0)).process()
   return dict(form=form)

[web2py] Re: 2to3

[Massimo Di Pierro]

you can use json-rpc2 with py4web but it is not built-into the framework. 
It does not need to be. I will post an example.

py4web has jwt auth support although the syntax is a different.

py4web is not as mature as web2py but very mature. The pros are the speed, 
the cleaner/leaner implementation and works better with third party 
modules. At this time more development is going into py4web than into 
web2py.

I think web2py remains the only choice for python2. If you are moving to 
python3 than you have a choice.

[web2py] web2py 2.21.1 is OUT

[Massimo Di Pierro]

Hello everybody, 

first of all my apologies to you all. I have been absent from this list for 
some time, mostly because busy with py4web.

I made a new release (2.21.1) of web2py which includes mostly small bug 
fixes but no new features. Please report any problem.

At this point web2py has been stable for long time so we are not planning 
to add features.

py4web on the other side is growing fast. It now has Auth, 
internationalization, Form, Grid and it is 20x faster than wb2py. pyDAL 
woks the in the same way as in web2py. I insist you should check it out and 
consider moving you code. It is easy and we will help.

Massimo

[web2py] Re: pyDAL looks abandoned?

[Massimo Di Pierro]

yes Peewee is more actcie but I would not say pydal is abandoned. pydal is 
more mature and there were commits as recent as last week. In my opinion it 
needs very little work and I am reluctant to change things. Many of the 
issues are requests for new features, some are how to, or support for 
exhotic features. There are also many issue that have been fixed but the 
issue has not been closed. When I have time I will take a pass and close a 
bunch.

I do not think there are many bugs in pydal that need fixing excecpt for 
the need to support google cloud storage in py3.

Re: [web2py] Re: WAF2PY 1.0

[Massimo Di Pierro]

py4web apps are not required to use vue. The auth page currently uses vue 
and some of the examples do but we are rolling out a new version of Auth 
that does not.

[web2py] Important about py4web

[Massimo Di Pierro]

There has been a lot of progress in py4web. 

Aside for the fact that it is faster and leaner than web2py it has the 
following features:
- simple pip install
- uses same pydal syntax as web2py
- uses same templates as web2py
- has Form, Grid, Auth, Flash, T, Cache, Dashboard & Tickets (need more 
work but all usable)
- out of the box support for SSO/OAuth2 including Google and Okta.

The pace of development of py4wb is much higher than web2py at this time.
We will continue maintain both and there is a fair amount of overlap.
Maybe some of the new py4web features can also be backported to web2py.

There are only 126 members in the google group, compared to 7900 here. You 
do not want to miss the boat.

[web2py] py4web grid

[Massimo Di Pierro]

For some people, the lack of a server side form/grid in py4web has been 
problem and reason not to move.
We now have a prototype:

https://github.com/web2py/py4web/issues/228

Could use some help testing and feedback.

Did you get it from github?
There was a recent change that maybe could have caused this:

https://github.com/web2py/web2py/commit/cf76978a390a70dfc36d3bfe64818fc0cc7226f3

Could you please revert it and see if it fixes your problem?

[web2py] Re: Column auth_user.id not found BUT the column exists.

[Massimo Di Pierro]

Somehow the table in db contains the field but the model does not.
We need to see you model.

Yes. Only on PostgreSQL, MySQL and Firebird. Assuming the feature has not 
been broken over time, I do not know of anybody who used it.

[web2py] Re: streamed pyfpdf is stored with wrong fileencoding when using python3

[Massimo Di Pierro]

Try a few things things:


1) set content type to "application/*pdf"*
2) set content type to "application/*pdf**; charset=latin1"*

*3) *

*from io import BytesIOreturn BytesIO(pdf.output(dest='S'))*

[web2py] Re: check url agrs / vars after #

[Massimo Di Pierro]

You cannot because the browser does not send those to the server. Your only 
option is to inject some JS in the page that reads it from 
window.location.hash and POST to an API, after the page is loaded.

[web2py] Re: [py4web] - how to disable some auth actions?

[Massimo Di Pierro]

Some of this is now done.
Please help test it:

[X] Enable and disable 
plugins 
  

[X} Enable and disable 
actions 
  

[X] Require passwords of various 
complexity  


[x] Force logout after x hours 
(WIP)   
  

[X] No re-use of the last n 
passwords   
 

[ ] Force new password on first login 
(WIP)   
   

[ ] Two-factor authentication for users with 'administrator' 
access  


[ ] Lock account after x failed login 
attempts.   
   

[ ] Force new password every x days.  

You need to copy this form _scaffold/common.py

auth = Auth(session, db, define_tables=False)
auth.use_username = True
auth.registration_requires_confirmation = settings.VERIFY_EMAIL
auth.registration_requires_approval = settings.REQUIRES_APPROVAL
auth.allowed_actions = ['all']
auth.login_expiration_time = 3600
auth.password_complexity = {"entropy": 50}
auth.block_previous_password_num = 8
auth.define_tables()

And you also need the new _scaffold/static/components/auth.js and auth.html 
copied into your own app


Instead of a minimum complexity (entropy) you ca specify a min length, 
number of required upper/lower case chars, and number special chars.

auth.password_complexity = {"min": 8, "upper": 1, "lower": 1, "number": 1, 
"special":1}

Personally I think this is EVIL. This is against the most recent NIST 
recommendations. An entropy of 50 is better. It forces long passwords that 
are easier to remember.

Re: [web2py] Re: Beginners question on Authentication ...

[Massimo Di Pierro]

Hello Jon,

unfortunately the documentation has been lagging. Recently we are putting a 
lot more efforts into py4web which, as you understood, is the natural 
successor of web2py. py4web is much cleaner and much faster. The Auth side 
is not quite as battle tested but we plan to release a new and improved 
Auth for py4web in a couple of weeks, maybe sooner. It is not quite true 
that py4web lacks the equivalent of web2py's grid. It is just different. 
py4web is designed for APIs and provides a mtable that generates grids 
client-side based on the APIs. There is a lot of new and better stuff in 
py4web which is undocumented but I will prioritize the py4web documentation.

Massimo

sorry again for the trouble with your questions. First post is always

[web2py] Re: [py4web] - how to disable some auth actions?

[Massimo Di Pierro]

Yes we should have these all but one. Will put it on the todo list. 
Rearranging in order of priority with some comments below:

1) Require passwords of various complexity (WIP= Work In Progress)
2) Force logout after x hours (WIP)
3) No re-use of the last password (WIP)
4) Force new password on first login (WIP)

5) Two-factor authentication for users with 'administrator' access
6) Lock account after x failed login attempts.
7) Force new password every x days.

NO) No sequential passwords (for example, can't change your password from 
'password1' to 'password2').
This is not possible because the server does not know the previous 
password, only the salted hash of it.
If a site enforces this, that site is storing your password in the clear 
and I'd recommend you not use it.

[web2py] Update on web2py binaries

[Massimo Di Pierro]

First of all thanks to Nico Zanferrari for all his work on creating new 
binaries. It took me a while but I have now incorporated them into my 
deployment process. You can find them here:

https://web2py.com/examples/static/nightly/web2py_win_py27.zip
https://web2py.com/examples/static/nightly/web2py_win_py37.zip
https://web2py.com/examples/static/nightly/web2py_osx_py27.zip
https://web2py.com/examples/static/nightly/web2py_osx_py37.zip

There are still not linked but please check them out. If they work for you, 
I will link them as official binaries.
For more info on the build process

https://github.com/nicozanf/web2py-pyinstaller

I then have have a process on my VM that unpacks and repackages them when a 
new web2py version is released. That is why I need help in testing them. 
Making sure the re-packaging did not break anything.

Thanks.

Massimo

[web2py] Re: Standard way of removing X-Powered-By: web2py http header?

[Massimo Di Pierro]

yes. This can be in the user's code:

response.headers['X-Powered-By'] = 'xping'

[web2py] Re: [py4web] - how to disable some auth actions?

[Massimo Di Pierro]

Let me give some thought to this. Only complication is a mechanism for 
sever to tell auth.js that some pages should be available.

[web2py] Re: py4web in Google App Engine route app

[Massimo Di Pierro]

There are two problems here:
1) you cannot symlink in an action because it must be done once and only 
once.
2) You cannot have paths like /_default because they are absolute paths

Assuming this is a linux or OSX machine you should do from the shell

$ rm -rf apps/_default
$ ln -s apps/myapp apps/_default

You only need to do this once.

 Have you pip installed py4web in the past?

 Can you cut and paste all of your terminal commands and output here to 
 recreate the problem?

[web2py] Re: how to expire sessions in py4web

[Massimo Di Pierro]

Session and login information are not same. The latter is stored in the 
former. When you logout it clears the login info in the session but does 
not clear the session. There is no need. You can of course do 
session.clear() if you want.

Sessions tells py4web (or web2py) that you are the same user as before. 
auth tells who you are and what you are authorized to do.

[web2py] Re: web2py upgrade from 2.16.1

[Massimo Di Pierro]

If you upgrade web2py to the latest and you continue to use python 2.7 
everything should work as expected. We do continue to promise python 2.7 
backward compatibility (and this is all that we promised).

If you chose to upgrade to python 3.7 than your app will probably no longer 
work. You will have to convert them from python 2.7 to 3.7. This is not 
web2py specific. We do not require that you do that. Yet the Python 
language developer have made the choice of no longer supporting python 2.7 
and therefore you should upgrade.

All we offer is, 1) if you port your apps, web2py will still work with 
them. 2) we offer py4web as a framework build specifically for python 3.7 
which supports a lot of the same APIs and is faster.

On second thought. This should be default because can be an information

[web2py] Re: Future of web2py

[Massimo Di Pierro]

It will continue fix bugs. I will add new features as long the same 
features overlap with py4web.
Honestly web2py has not needed much attention in a while.
I do recommend that people move their apps to py4web simply because I 
believe the latter is better.

[web2py] Re: py4web translations

[Massimo Di Pierro]

You have to pass T to the view

@action('index')
@action.uses('index.html', T)
def index():
 return dict(message="hello world", T=T)
# in view  [[=T(message)]]

or 

@unauthenticated
def index():
 return dict(message="hello world")

and it is all automatic. Need the latest common.py from scaffold.

[web2py] Re: PY4WEB socketIO

[Massimo Di Pierro]

It would be trivial to implement it like flask does. 

You can do it right now using the bottlepy way:
https://pypi.org/project/bottle-websocket/
or
https://github.com/marlboromoo/bottle-socketio-example
py4web uses bottle under the hood.

The problem is that I would like something better than that.
I am not convinced it would work well in a cloud setting o when you have 
servers behind a load balancer.

Imagine you have two chat clients connected to two servers. If your client 
posts a chat message, how does one server notify the other server to notify 
the other client? This is the hard problem to solve. I am not interests in 
toy examples. py4web will have this.

Massimo
