[web2py] time field in DAL? when I retrieve it, it gives me as nontype instead of time type.
I tried to compare by doing
{{=row.start_hour request.now.time()}}br/
start_hour is defined as 'time'
error :
TypeError: can't compare datetime.time to NoneType
How can I convert time field to be time type? so I can compare them.
Also, one last question is how can I show times in different timezone?
Do I need to use pypt?
thank you.

Re: [web2py] 2.6, 2.7, 3.2, PyPy ... wich one to use?
As far as I understand, Web2py is developed using 2.5 features. So, the framework itself officially supports v2.5 and this is good. But it doesn't mean you cannot use 2.7 to develop your application based on the framework. I, personally, always use the latest Python stable release. There's no reason to use a past one when you develop your apps. Unless you can't upgrade your production environment. -- Vinicius Assef On Thu, Mar 29, 2012 at 7:38 AM, Sergi Pons Freixes sachiel2...@gmail.com wrote: 2012/3/29 Jonathan Lundell jlund...@pobox.com: Latest 2.7.

[web2py] Re: Dynamically create form ?
More generally, all web2py HTML helpers (including FORM and SQLFORM) act
like Python lists with respect to their components, so you can use all the
Python list methods, including .insert and .append. Helpers also act like
Python dictionaries with respect to their attributes (i.e., named
arguments), so you can used dictionary methods like .update for attributes.
Subscripting works as expected as well.
See http://web2py.com/books/default/chapter/29/5#HTML-helpers.

Re: [web2py] 2.6, 2.7, 3.2, PyPy ... wich one to use?
I thought 2.5 was the recommended option for web2py. From the book: ...on Python versions 2.4, 2.5, 2.6, and 2.7 That's not quite correct, as 2.4 is no longer supported. although officially it only supports 2.5 so that we can guarantee backward compatibility for applications. I'm not quite sure what that's supposed to mean. Perhaps it simply means that if you develop an app targeted at 2.5, you are guaranteed to be able to run that app anywhere web2py itself can run (i.e., down to 2.5), but if you develop an app targeted at 2.7, it will only run on 2.7 (and therefore not everywhere web2py can run). If that's what is meant, it could probably be stated better. It's not really an issue of backward compatibility of the app, I think. Anthony

[web2py] Re: Check to delete:False
SQLFORM takes delete_label and separator arguments. Previously (at least up to 1.99.2), delete_label defaulted to Check to delete:, and the separater was not appended. At some point since 1.99.2, it was changed -- now delete_label defaults to Check to delete, and separator (which defaults to : ) is appended. I think this was done (a) to correct the problem with the missing space after the : in the original label and (b) to make the separator for the delete record label consistent with the other labels. The default behavior is the same as before (except for the inclusion of the trailing space), but if you were doing something other than the default, the output could change. It looks like you might have separator=False, so False is getting appended to the label. If you just remove any explicit delete_label and separator arguments, you should get what you're looking for.

[web2py] Re: Python Negative Popularity
I'm not convinced that the stats you cite about Python are statistically meaningful over a one-year period (2.45% decline?). But it seems to me that on the web the key issue is browser integration. JavaScript is the default language of the web because browsers all interpret it internally. PHP, you'll notice, also saw a small decline in these stats. I think that's related to the desire to do as much as possible in the browser (client-side). As long as that is the push, and as long as Python doesn't have client-side support built-in, it will always be in a second-class position on the web. I actually think that one of the strengths of Python is that it doesn't have to run on a server--it can work equally well with a native local interpreter. But so far in web development we have treated it as a drop-in replacement for PHP (and so as server-dependent) rather than as a language to run locally on the client. That said, I think the expansion of the Python web ecosystem beyond Django can't but help the language's profile. This is not to slam Django, but as long as a language is perceived as a one-framework show (like Ruby and rails) it will tend to have trouble making converts.

[web2py] Tracking/Tracing actions
Hello,
I am working on a secure documentation system that should support file
uploads but also to give the ability to trace user actions like
download/upload of files. This should be integrated in the portal itself so
that the administrator doesn't need to parse web log files and trace users
and IP's. Example:
user Malkovich submitted a file: report.docx with hash: 102310239123123 at
2012.03.27 10:12:45 (GMT)
user BigFatCat downloaded the file: report.docx (id: 1201010121)
at 2012.03.27 12:11:05 (GMT)
...
So, I just said what I have and I want, so now let me tell have I done
about this:
in the model:
...
db.define_table('attachment',
Field('name', requires=IS_NOT_EMPTY()),
Field('filename'),
Field('description'),
Field('doc_type',
requires=IS_IN_SET(['text','report','image','other']), default='other'),
Field('hash', 'string'),
Field('file','upload'),
format='%(name)s')
db.define_table('logs',
Field('message','string', requires=IS_NOT_EMPTY()),
Field('full_description','text'),
Field('action', 'string',
requires=IS_IN_SET(['create','remove','download','upload',
'edit','other']),default='download'),
Field('attachments', 'list:reference attachment', notnull=False),
Field('user', 'list:reference auth_user'),
Field('happened_on','datetime', default=datetime.datetime.now()))
...
in the controller:
def hash(file):
return hashlib.md5(open(file).read()).hexdigest()
@auth.requires_login()
def insert_file():
form = SQLFORM(db.attachment, upload=URL('download'), fields=['name',
'description', 'file'])
if request.vars.file!=None:
form.vars.filename = request.vars.file.filename # not sure about
this one...
form.vars.hash = hash(file)
if form.process().accepted:
db.logs.insert(message='file submitted',
full_description=forn.vars.hash, action='upload', attachments='',
user=auth.user.id, happened_on=request.now)
response.flash = 'form accepted'
elif form.errors:
response.flash = 'something went wrong, try harder'
record = db.attachment(request.args(0)) or redirect(URL('index'))
return dict(form=form)
...
This is not yet working but don't think I am on the right track? Tips?
Thank you

[web2py] Re: Versions earlier than 1.77.1?
Unfortunately the code blows up with current web2py - something about 'updateable' views no longer being allowed. What does updateable views mean? Are you talking about generic views? If so, they can be enabled via the following in a model file: response.generic_patterns = ['*'] Though for security reasons, it's not recommended to be quite so liberal with allowing generic views. See http://web2py.com/books/default/chapter/29/10#Generic-views. If that's not the issue, have you actually tried version 1.77 (or other later versions) -- even if you app doesn't work with 1.99, it might work with some other earlier version. Anyway, perhaps Massimo has older versions available somewhere. Anthony

[web2py] Re: How to Save Query in Session
I think it would be nice to have a way to serialize DAL queries. The problem is should the serialization be database dependent or not. If database dependent it is easy because we can just store the SQL. Yet it would not work for noSQL. My dream has always be to have a non-database-dependent serialization. This would allow creation of a proxy adapter so that two instances of DAL can query each other.

[web2py] Using routes.py as a dispatcher for URL shortener app
hi all,
So I am coding a little app that acts as a sort of url shortener (like
bit.ly).
Visiting *myapp.com/tcgata* will search my database for an URL linked to '
tcgata'
My reading of the documentation suggests that this can be achieved using
pattern-based URL rewriting in routes.py. As such I made the following file:
routes_in = (
('.*[a-zA-Z0-9]{6}', '/catchAll'),
)
#in default.py
def catchAll():pass
where catchAll is a controller function that will glean the search string
('tcgata') from the request object and redirect to the relevant URL (or 404
if not found). Currently it is a passed function.
However, the redirection doesn't seem to be working for me. When I visit
myapp.com/tcgata i get an error page saying *'invalid function
(default/tcgata)'*.
Where am I going wrong? Is it a routing issue? a regex issue? I am sure it
is something simple I am missing, but I think I need some extra eyes to
find it.
Furthermore, if there is an easier way to do what I am seeing to achieve, I
am all ears!
thanks in advance

[web2py] Re: Python Negative Popularity
I'm not an expert in statistics but 2.45% decline is a lot because that relates to the whole language ecosystem. If you look at the numbers specific to Python, it means a drop from ~7% to ~3% which is about 50% decrease concerning what Python was a year ago. Now, this a metric, it's value,it's meaning and importance are something else. I know in a web2py group we are easily interpreted as biased but Massimo is very right on the constraint of Python to Django. Not technically because Python is probably the language with more alternatives on this but politically. The multicore advancement is not a Python specific problem. While python may not be prepared for that from scratch it is as well prepared (or better) when compared to its competitors. Also, Erlang and Scala are still a long way from becoming major choices. Finally, Javascript is winning everyday more steam. It's one those causes where programming languages are not there to help programmers, it's programmers that are helping them ;) On Thursday, 29 March 2012 17:26:48 UTC+1, Massimo Di Pierro wrote: I believe the non-backward compatibility of Python 3.0 and the monopolization of major conferences by Django (which was great 5 years ago but it loses to most of the other frameworks by now) are part of the cause.

[web2py] Re: Using routes.py as a dispatcher for URL shortener app
Having recently completed my own personal URL shortener app on web2py, the
trick was using pattern based routes at the root level. Actually, even for
a fairly complex work-related app we had to use the root-level routes.py as
well. Specially with an URL shortener, you want to have the URL as small as
possible (else it sorta defeats the purpose), so you are going to need
something along the lines of:
routes_in = (
(r'^/?$', r'/app_name/default/index'),
(r'^/(?Purl[^/]*)/?$', r'/app_name/default/index/\gurl'),
)
in your root-level routes.py The drawback is that you will lose access to
all other apps (including admin) but that can be a good thing for public
deployments.

hi all,
So I am coding a little app that acts as a sort of url shortener (like
bit.ly).
Visiting *myapp.com/tcgata* will search my database for an URL linked to '
tcgata'
My reading of the documentation suggests that this can be achieved using
pattern-based URL rewriting in routes.py. As such I made the following file:
routes_in = (
('.*[a-zA-Z0-9]{6}', '/catchAll'),
)
#in default.py
def catchAll():pass
where catchAll is a controller function that will glean the search string
('tcgata') from the request object and redirect to the relevant URL (or 404
if not found). Currently it is a passed function.
However, the redirection doesn't seem to be working for me. When I visit
myapp.com/tcgata i get an error page saying *'invalid function
(default/tcgata)'*.
Where am I going wrong? Is it a routing issue? a regex issue? I am sure it
is something simple I am missing, but I think I need some extra eyes to
find it.
Furthermore, if there is an easier way to do what I am seeing to achieve,
I am all ears!
thanks in advance

Good point, Anthony. I forgot they are evaluated in order. So you can declare them explicitly before the generic pattern and achieve the same result.

I have another view default/index.csv that renders the variables (e.g. as a,b,c) and this downloads ok as a file (with filename index.csv) if I visit the url ../default/index.csv I added a form to index.html, with a submit button called 'download', in the index controller, if the user has clicked the 'download' button, I am trying to use response.view or response.render to do the equivalent of manually visiting the url that ended in '.csv' Various failed attempts so far, I either get a view on the screen with 'None', or view not found, or currently:- if request.vars.btn == 'download': response.view = 'default/index.csv' return locals() else: return locals() the above causes the index.csv to be displayed in the browser with html,header and body tags (which are not in the view), how do I get this 'view' to be downloaded as a file named 'index.csv' !?

This is not a problem for web applications. I also think the drop to be significant although not necessarily a long term trend. Python could rebound easily by: - extending the life of 2.x with 2.8 (including as much goodies from 3.x as possible but backward compatibility) and promising LTS - merging stackles and/or gevent - including a standard request/response objects in the libraries - include the request library as replacement for urlib/urlib2 - provide a windows distribution which includes PIL/NumPi/SciPy and is not commercial - stop the Django community from monopolizing every forum (it is still losing to Rails and therefore not the future) and emphasize diversity. - stop the purists who do bash Python projects that are working and popular for not being Pythonic (whatever it means, you do not hear of Java projects not being Javonic). - go back to target schools. I was at PyCon and it is mostly a recruiting place where consultants advertise themselves and their companies. Very few talks are technical. Meanwhile many schools are moving away from Python in favor of JavaScript. This makes no sense to me but perhaps there is something that can be done.

[web2py] Email verification for user registration
Hi Group, I am trying to implement a fairly standard procedure for user registration: after a user submits his/her email address, an email is sent, and by clicking on the link contained in that email, the user is registered. How do we implement this without writing anything to the DB until the user has clicked on the link in the email? This should work even if the user closes the browser and confirms his/her registration a few days later. I have a custom user account/authentication table, so would like to use that for this. Is there any example I can follow? Thanks.

Re: [web2py] Login username fake ending character
If i am correct this will not work because it should be:
1. check last character
2. remove last character
3. do db validation
I think onvalidation does db validation and then 12.
Db validation will not pass because usernames are stored without last
character (as stated in first post).
Not sure if I am right but should be easy to check :)

[web2py] Re: Versions earlier than 1.77.1?
That's one thing about web2py is that it's stated backwards compatible
throughout the documentation. The error you're having is being thrown by
the sql server. If your view is comprised of multiple base tables, your
update statement needs to only affect one of those tables at a time. So if
there are three tables in your view, you need to have three update
statements.

Though for security reasons, it's not recommended to be quite so
liberal with allowing generic views. See

If that's not the issue, have you actually tried version 1.77 (or

[web2py] Re: Smarttable SQLFORM.grid
I get what you are saying. I wrote a function (not on web2py, but it's
javascript...)
// this will capture the 'enter' key when pressed inside the text box, so
searching works better.
function IEKeyCap(e)
{
if (e.keyCode == 13) {dsCustomers.filter(myFilterFunc)};
}
function FilterData()
{
dsCustomers.filter(myFilterFunc);
}
function StartFilterTimer()
{
if (StartFilterTimer.timerID)
clearTimeout(StartFilterTimer.timerID);
StartFilterTimer.timerID = setTimeout(function() { StartFilterTimer.timerID
= null; FilterData(); }, 100);
}
and here was my html that fired it...
input class=searchbox onkeyup=StartFilterTimer(); type=text
name=srch id=srch
This was using the Adobe Spry framework, but it's essentially the same.
When you press a key, it starts the timer (for 100ms). If the timer was
already going and you press another key, it restarts the timer.
After 100ms, it then calls the filter function. If they press enter
(keycode 13) it will also call the filter function.
I think the problem here is that the SQLFORM.smartgrid isn't AJAX, in that
when you click 'search' instead of just reloading the grid with the
filtered data, it just redirects you (to the exact same page you're on) and
shows you the filtered data.
The only way I know to do it with AJAX is to write my own smartgrid, or use
Adobe Spry Framework because it's awesome - and you can just tell web2py
that you want that dict as a json.

[web2py] How to use web2py auth using JavaScript+ajax?
I need to do a major rework in order to move client-side functionality to the browser and using Javascript to get more responsive client side experience with no refresh etc. That means web2py will give a rich server side functionality and all client work to be performed via JavaScript and Ajax. I made several tests and see this integration working just perfect. I successfully implemented auth with web2py. Now I need to make possible login/logout with just Javascript and Ajax snd calling web2py auth remotely. How to implement it so that I get the same functionality with sessions, etc? Assuming this is working, then how to retain the users' session state? Thanks in advance,
[web2py] Re: Python Negative Popularity
Guido is working for Google. GAE is having Python as a primary language - e.g. all libraries are implemented on Python first, Java and Go next. So we get a priority for Python. So from GAE point of view you better use Python to have an advantage. If not using GAE what alternatives we have? PHP is not secure and is outdated. Google refuses to use it on GAE for security reasons. Javascript is the only possibility for the client side, node.js makes it possible for server side. Java is bloated, inefficient, etc. So basically it boils down to two options: Javascript and Python.

I am confident the 'id' will work, but it doesn't address the other

The next thing I will try is to do some db interaction without forms or

Can you help me?
Is it better is_in_set or sqlform.factory?
[web2py] Storing class instances in sessions... or somewhere
I have an existing application that I am trying to get running as AJAX with web2py (locally, but eventually to run on GAE). The application makes use of class instances to store much of the data which would be used for user sessions. I understand that session can't be used to store class instances but for the time being I want to keep the instances for each session (about 200K of data). Sooner or later I guess I will need to save this data in the data store, but at the moment I'm trying to get a prototype up and running and reworking the code to get the data into/out of a database is more pain than I can face atm. The instances are pickleable (well, cPickle doesn't complain) My options seem to be: * cache in ram using the session id as a key and * dumping the instance to a string, saving the string to session (on GAE will this be the same as cache.ram?) Are there other approaches? What's the best way to go about this? Also, in the next update of the documentation, this would be a useful detail to include on the session related sections. Thanks in advance Brendan
[web2py] Re: pop-up verification
Take a look at this: http://web2py.com/books/default/chapter/29/7#FORM
Specifically this example:
db.define_table('numbers',
Field('a', 'integer'),
Field('b', 'integer'),
Field('c', 'integer', readable=False, writable=False))
def my_form_processing(form):
c = form.vars.a * form.vars.b
if c 0:
form.errors.b = 'a*b cannot be negative'
else:
form.vars.c = c
def insert_numbers():
form = SQLFORM(db.numbers)
if form.process(onvalidation=my_form_processing).accepted:
session.flash = 'record inserted'
redirect(URL())
return dict(form=form)
What you want to do is write your own validator, so that it will check if
the data is already in the database, and if so, modify the form such that
there is an extra checkbox 'i am sure that i know that this is already
there'.
Perhaps that will help?

Last question of the day, I promise...
So, I have data that exists in my database. If a user enters a value

How do I interrupt my current function to do so without leaving the page
and losing data?

[web2py] Re: Date field mask or another value
is certainly a valid year. 99 could be a valid calendar month,
depending on your calendar. You should probably specify what the valid
range of values are.
Try the IS_MATCH with a regex.

Hi,
I want a field (may be string,date or number, no prob) to have a
format of MM (valid year and month) or if it is left null, to be
99. How Could I accomplished that?
I have tried :
Field('A0514_DT_FIN','date',notnull=True, label= 'Dt Fim (MM)',
default= '99')
and then the check:
db.tb0514_bihc_consultor_nivel.A0514_DT_FIN.requires =
IS_EMPTY_OR(IS_DATE(format=T('%Y%m'), error_message='formato deve ser
MM! ou vazio'))
It does not work as 99 is not a valid month and is not a valid
year.
Any ideas?
[web2py] Re: Email verification for user registration
Web2py has some functionality built-in that may work for you. In a model file: auth.settings.registration_requires_verification = True I don't know the exact behavior.
[web2py] Re: Agree on some terms before registration
add a boolean field to the registration page and require it to be true
auth.settings.custom_fields['auth_user'].append(Field('agree','boolean',requires=IS_NOT_EMPTY(error_message='you
must agree this')))

Re: [web2py] Tracking/Tracing actions
I need to create a form that submits files and at the same time, stores the
user who did it, the name of the file, its hash, the time. Other things like
his IP address, his web client would be interesting as well.
I see two ways:
1) some sort of method tracing (a decorator maybe) that informs me what calls
have been done to some controller
2) include in the uploading form, insertions to the database that also keep
track of what has been done (the solution I'm trying)
While I want to keep files metadata stored on the database, I want them to be
stored on the file system. So how can I create a form that uploads the file and
stores all this metadata on the database (including getting the filename, its
hash,...)?

Hello,
I am working on a secure documentation system that should support file
uploads but also to give the ability to trace user actions like
download/upload of files. This should be integrated in the portal itself so
that the administrator doesn't need to parse web log files and trace users
and IP's. Example:
user Malkovich submitted a file: report.docx with hash: 102310239123123 at
2012.03.27 10:12:45 (GMT)
user BigFatCat downloaded the file: report.docx (id: 1201010121) at
2012.03.27 12:11:05 (GMT)
...
So, I just said what I have and I want, so now let me tell have I done about
this:
in the model:
...
db.define_table('attachment',
Field('name', requires=IS_NOT_EMPTY()),
Field('filename'),
Field('description'),
Field('doc_type', requires=IS_IN_SET(['text','report','image','other']),
default='other'),
Field('hash', 'string'),
Field('file','upload'),
format='%(name)s')
db.define_table('logs',
Field('message','string', requires=IS_NOT_EMPTY()),
Field('full_description','text'),
Field('action', 'string',
requires=IS_IN_SET(['create','remove','download','upload',
'edit','other']),default='download'),
Field('attachments', 'list:reference attachment', notnull=False),
Field('user', 'list:reference auth_user'),
Field('happened_on','datetime', default=datetime.datetime.now()))
...
in the controller:
def hash(file):
return hashlib.md5(open(file).read()).hexdigest()
@auth.requires_login()
def insert_file():
form = SQLFORM(db.attachment, upload=URL('download'), fields=['name',
'description', 'file'])
if request.vars.file!=None:
form.vars.filename = request.vars.file.filename # not sure about this
one...
form.vars.hash = hash(file)
if form.process().accepted:
db.logs.insert(message='file submitted',
full_description=forn.vars.hash, action='upload', attachments='',
user=auth.user.id, happened_on=request.now)
response.flash = 'form accepted'
elif form.errors:
response.flash = 'something went wrong, try harder'
record = db.attachment(request.args(0)) or redirect(URL('index'))
return dict(form=form)
...
This is not yet working but don't think I am on the right track? Tips?
Thank you
