Re: [web2py] Is it possible to restrict a user to single login instance ?
All, Let me clarify a little - since lot of answer seemed to focus on MachineA Vs MachineB What I need is only one valid session from UserA at given point - so two sessions - one from Chrome and other from Firefox - both from MachineA - should be disallowed. (Not sure if it makes problem easy or difficult) *Theoretically* I am thinking following : in pre-login (if I can intercept login attempt) - put a code that checks whether user that is trying to login - has already logged in (and not logged out yet) If yes, do not allow the login (or somehow forcely invalidate other session - and allow this login attempt to go thru) *But I am not sure how this maps to web2py flow/hooks etc*.

Let me clarify a little - since lot of answer seemed to focus on MachineA Vs MachineB What I need is only one valid session from UserA at given point - so two sessions - one from Chrome and other from Firefox - both from MachineA - should be disallowed. (Not sure if it makes problem easy or difficult) You still need to be able to distinguish one machine/browser from another in order to know whether a given login request is coming from a different client. The user agent will tell you if a different browser is being used (though it can be spoofed, so this is not a security measure), but that won't help if someone is using the same browser on two different machines (also, what kind of app requires that users should not be able to log in from different browsers on the same machine?). And as already mentioned, there are limitations to using IP address to uniquely identify machines. *Theoretically* I am thinking following : in pre-login (if I can intercept login attempt) - put a code that checks whether user that is trying to login - has already logged in (and not logged out yet) If yes, do not allow the login (or somehow forcely invalidate other session - and allow this login attempt to go thru) Maybe add a session_id field to db.auth_user, and when a user logs in (a) check that field, and if it has a value, delete the session file associated with the existing ID (if it exists) and (b) store the new session_id. Note, this won't work with cookie based sessions -- in that case, you would instead have to check the session_id value stored in db.auth_user on every request in order to catch and invalidate the session cookie from the older session (this adds a db lookup to every request -- might want to cache these in RAM, though you may need to clean up periodically if there are a large number of users). Also, note that this doesn't protect against session hijacking. It only protects against multiple simultaneous logins (which would be using different sessions rather than sharing a single hijacked session).

if it's a module yes, it's the whole reason of having a module not to reevaluate it at every time. If you're debugging, though, it should be a function.

[web2py] Re: Semantic UI instead of bootstap
It's good for the widgets but not the grid. It looks better by itself than to mix with others like zurb and bootstrap. It's a tad bigger, and different kind of style. Out of the box, I personally did not find its styling as nice as zurb and bootstrap, and it requires to input quite a bit of code to produce. There was a widget that I couldn't get it to display properly, and there was no easy way to search for answers on stack overflow or google like the others (because it's much younger) I tried but gave up and went with another instead. That was when I needed to change my code and boy... it's an overhaul.

Is there a way to prevent this from happening?
Furthermore, in case of an update form the form does not indicate that an
image file has already been uploaded, the image
field is a browse button and the message 'no file selected'.
I read the book's part on an image blog and SQLFORM and uploads, in the
examples the image field shows a file link and an
option to delete just the image not the record. I did not get this to work
for I wasn't able to figure out how upload=URL('download')
works. In case of the img_logo table it has the following scr selector:
scr=“/myleonexus/image/download/img_logo.image.beca…67.png”
where myleonexus is the application, image is the controller, but download
is not a function in the image controller.
In case of you solution:
folder = 'nodeID' + str(nodeID)
db.img_logo.image.uploadfolder =
os.path.join(request.env.applications_parent, 'applications', 'dbmodel',
'static', 'uploads', folder)
Is it possible to use upload=URL('download') or not?
Best,
Annet

[web2py] GRID selectable inside component

expected. But from the component page it doesnt execute the callback.

When you say it somehow doesn't work, do you just mean the old session file remains, or is something else not working? Yes. Session file does not get deleted. The side effect of session file remaining on the disk is that if the hijacked session ID is used by the attacker - then somehow contents of the session file on the disk are reused (even if session contents from memory (Storage object) are cleaned) Thus allowing the attacker access to logged in page without actually having to login. So now I'm explicitly deleting the session file. BTW - which method gets invoked when session has expired ? Is there a hook where I can add the code to delete the session file - in addition to post_logout ? This may be better than too frequent cron job with session2trash script. -Mandar What I want is something like sessions2trash.py script - except that file should deleted right away - even if the session has *not* expired. Currently I'm using something like following. *Please suggest correct way to handle this* (I know this works only for file based sessions, but that is OK) def post_logout(user): try: import os os.unlink(response.session_filename) # Clear the session from disk except OSError: pass session.renew(clear_session=True) # Clear the memory/Storage object.

[web2py] Re: Apostrophe causes new column in PYFPDF
I have found the problem. It's not the HTML helpers that are escaping twise.
The problem is that gluon.contrib.generics.pyfpdf_from_html calls sanitize
on the input.
P(Row's).xml()
'pRow#x27;s/p'
from gluon.sanitizer import sanitize
sanitize('pRow#x27;s/p')
'pRowamp;#x27;s/p'
sanitize('pRow#x27;s/p', escape=False)
'pRowamp;#x27;s/p'
This is where things are being escaped twice. So this seems like a bug in
gluon.sanitizer.XssCleaner which shouldn't escape entities that are already
escaped.
Even after this bug is corrected, we would still have to unescape the input
at least in gluon.contrib.generics.pyfpdf_from_html before calling
pdf.write_html since the HTMLParser in fpdf isn't doing it.

It may be worth having web2py delete the file (or database record in the case of database based sessions) automatically upon session.renew(). Maybe submit a Google Code issue about this. BTW - which method gets invoked when session has expired ? Is there a hook where I can add the code to delete the session file - in addition to post_logout ? First, although login can expire, sessions themselves do not expire (they simply terminate when the browser session ends by virtue of the fact that the browser will no longer transmit session cookies for old sessions). In any case, there is no process that can monitor sessions/logins for expiration automatically (i.e., no place for a hook). The only events that the framework can respond to are requests, but an inactive client is not making any requests, so there would be nothing to trigger an expiration check. If you want to monitor logins for expiration and proactively delete session files or database records, you would have to run an external process (i.e., something like sessions2trash), perhaps using the scheduler or some other mechanism. To prevent session hijacking, keep all logged in activity (including the login itself) over HTTPS. If you're still concerned, delete the session file upon logout (as you are now doing) and run sessions2trash periodically. Trying to delete the session file at the precise instant of login expiration will add little to overall security.

Hi again,
So a friend of mine helped me solving the issue, on gluon/custom_import.py,
on line 82 we have to replace this line:
modules_prefix, globals, locals, [itemname], level)
With this one:
modules_prefix, globals, locals, [itemname*.encode('utf-8')*], level)
And that's all!.
Thanks for your support!

[web2py] What are .table files in sqlite databases?
Dear all, I am trying to backup my sqlite databases using its backup API: sqlite3 storage.db .backup db.bak I noticed it made a copy of storage.db. But how about all those .tables files. I search about sqlite and web2py, seems nothing came up about them. Using ls -l, I can tell most these .table files have not been modified for a long time. So no data is in them. Should I back up them or not? Thanks! -- Yi -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: What are .table files in sqlite databases?
Table files have nothing to do with sqlite. They are files generated by web2py with the table structure, to detect changes and perform migrations. You don't necessarily need to keep them in your backups, you can do a fake migration to generate them again. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: nested for loop and pass in view
The a element in the inner loop only references the question variable,
which is set in the outer loop. Perhaps instead of question, you menat to
put correct_questions[record].

Had to run the first for loop to get into the keys and then compared
values.
I've modified the code to do check if the question was answered correctly
in the controller and append the question id to a list. Still not
working... here is my controller:
def questions_for_people():
correctList = []
correct_questions = db((db.questions_answered.correct==on)
(db.questions_answered.answered_by==auth.user.id)).select(db.questions_answered.ALL,
groupby=db.questions_answered.question, distinct=True).as_dict()
for row in correct_questions:
for item in all_questions:
if correct_questions[row]['question'] == item['id']:
correctList.append(int(item['id']))
return dict(correctList=correctList)
and in my view:
ul
{{for question in all_questions:}}
{{if question['diff_level']==100 and question['id'] not
in correctList:}}

Hi Anthony,

In your original code, the inner loop looped over correct_questions, but in
the menu items, you did not reference the correct_questions item and
instead referenced the question item from the outer loop -- that is why you
saw the same menu item repeated multiple times.
I've modified the code to do check if the question was answered correctly

Why use .as_dict()? If you leave it as a Rows object, you can refer to
row.question instead of having to do correct_questions[row]['question'].
Also, what is all_questions? Do they come from another db table, and if so,
is it linked to db.questions_answered? Perhaps you could just do a single
db query (via a join) to get the data you need.
ul
{{for question in all_questions:}}

If nothing returns, then presumable question['diff_level'] never equals
100, as both if statements include that condition. Also, rather than
nesting the second if inside an else, you can simply use an elif.

[web2py] Refresh DIV onclick
I tried to search through most of the forums before submitting my question
but I couldn't seem to find what I was looking for.
When a user submits their answer I would like to do two things:
if it is accepted and its corrected I would like to refresh the page, but
if its not correct I would just like to refresh the div that has their
submitted answers.
my controller is:
def submit_answer():
answer=FORM('Answer: ',
INPUT(_name='answer', requires=IS_NOT_EMPTY()),
INPUT(_type='submit', _class='btn btn-primary',
_id=sub_button))
if answer.accepts(request,session):
#session.tabTracker = request.vars['chal']
answer_comp =
db(db.answers.id==int(request.vars['chal'])).select(db.right_answers.ALL).first()
if answer.vars['answer'] == answer_comp['answer']:
response.flash = 'Correct! Nice job!'
else:
response.flash = 'Incorrect answer'
elif answer.errors:
response.flash = 'Please submit your answer'
else:
response.flash = ''
return dict(answer=answer)
and my view:
{{=LOAD('board','submit_answer.load',
vars={'chal':question['id']},ajax=True)}}
The name of the div I would like to refresh is: div class=panel-heading
I've tried the response.js solution Anthony posted in another forum, but it
didn't seem to work.
I know web2py has a onclick= feature and I'm thinking thats the way to go,
but not sure how to structure it

[web2py] Re: Refresh DIV onclick
UPDATE: This works well for me after the form submits: redirect(
request.env.http_web2py_component_location,client_side=True)
That came straight from the book, but its when the student gets a question
wrong is where I'm running into trouble. I'd like to just refresh the div
so they could continue to enter answers.
