hi,
thanks! That solved my ~ problem.
Unfortunately for my öäü (chars above 128 and below 255 in latin-1) I
still need to overcome 2 challenges:
1. re.U must be supplied to compile or match to take advantage of
unicode interpretation of \w.
I could shift compile into the routes.py. Is it acceptable?
I think so, yes.
2. at some point before match call args have to be subjected to
decode('utf-8') to become unicode
Any suggestions?
I'd like to do this right, but I'm a little confused. Do we need to consider
Punycode, for example? Or is that just for domain names?
what I mean is very trivial:
***
*** 915,925
def validate_args(self):
'''
check args against validation pattern
'''
for arg in self.args:
! if not self.router._args_match.match(arg):
raise HTTP(400, thread.routes.error_message %
'invalid request',
web2py_error='invalid arg %s' % arg)
def update_request(self):
'''
--- 939,949
def validate_args(self):

for arg in self.args:
! if not
self.router._args_match.match(unicode(arg,'utf-8')):
raise HTTP(400, thread.routes.error_message %
'invalid request',
web2py_error='invalid arg %s' % arg)
This makes the validation pass. The args are still passed down to
application as char and have to be again converted there into Unicode.
Ideally framework should make it happen once.

hi,
of directory traversal attacks (~ specifically).
how exactly?
I am talking about arguments and only arguments.
I agree that ~ in case of application/controller/method makes no sense
In case of static agree 100%, but that is different control path.
If you enable the parametric router, you'll get the kind of args handling
you want, with the added feature that you can rewrite the args validation
regex.
The arguments are just that, arguments. If you put such a blanket
statement about arguments in url, should you also do it for forms? At
the end these are also arguments and someone may take it 1:1 and feed
into 'open'.
It is up to the controller to decide what to do with args. I believe
nobody takes anything what comes from browser (args or form elements)
and try to use it as argument of the 'open'. In case of web2py, DAL
delivers already a perfect mechanism to take whatever comes and
convert into reasonable name:
filename=db.table.field.store(content,whatever_convoluted_name_we_get).
To be specific about the args filtering:
agrs must match:
regex_args = re.compile(r'''
(^
(?Ps
( [\w@/-][=.]? )* # s=args
)?
/?$) # trailing slash
''', re.X)
what I suggest is:
regex_args = re.compile(r'''
(^
(?Ps
( [~\w@/-][=.]? )* # s=args
)?
/?$) # trailing slash
''', re.X|re.U)

[web2py] Re: list of usernames
Thank you Anthony.
I will need to exclusively modify the variable status on other
occasions. So I am not sure I really want computed fields. Is that
true ?
So I decided to try an onvalidation function and I ended up with :
def status(form):
form.vars.status = [0]*len(form.vars.to)
def write():
form = SQLFORM(db.message)
if form.accepts(request.vars, session, onvalidation=status):
response.flash = 'Got it'
It seems to work.
Is it ok ? If I have understood correctly, onvalidation is called
after validation and before insert. Like this I am sure
forms.vars.to does not contain anything fishy or dangerous.
Thanks,
Archibald

All this works very nicely.
Maybe the default format for auth_user should also be documented.
Let's say I have the following table :
db.define_table('message',
Field('to', 'list:reference auth_user'),
Field('status', 'list:integer'))
I want status to be a list of 0 as long as to, but
db.message.status.default = [0]*len(db.message.to.default) does not
work.
db.message.to.default represents the default value for the 'to' field (which
you have not set), not the actually values being inserted. Anyway, I don't
think the default for one field can reference the values of another.
There are a few other options. You could use a computed field (though by
default that won't display in a form, if you need that). If inserts/updates
will always be handled via form submissions, you could us a form
onvalidation function or a custom validator. You could also just do
default=[0]*len(request.vars.to), since upon form submission, the values
submitted to the 'to' field will be stored in request.vars.to (note, the
values stored in request.vars will be the unvalidated values). See here for
more

[web2py] Re: Nested functions problem?
I tried:
Controller:
def imagetext():
id=request.args(0)
image=db((db.bedrijfimagelink.bedrijf_id==id).select(db.imagelink.link).first()
text=db(db.hptext.bedrijf_id==id).select(db.hptext.tekst).first()
return dict(image=image,text=text)
View:
div id=component
{{=LOAD('locator','imagetext.load',args=283,ajax=True,target='component')}}
/div
and the second view locator/imagetext.load:
{{if image:}}
div id=banner style=text-align:center; height: 120px;
{{=IMG(_src=URL('static','init/images/banners/%s' % image.link),
_width=696px, _height=120px)}}
/div !-- banner --
{{pass}}
{{if text:}}
div class=oneColLayout
div style=margin: 24px 36px 0px 36px
{{=XML(text.tekst)}}
/div !-- box --
/div !-- oneColLayout --
{{pass}}
But the div displays Loading... instead of the text and the image.
I also tried:
Controller:
def businesscard():
if not len(request.args):
redirect(URL('default','error'))
else:
id=request.args(0)
...
functions=db(db.function.bedrijf_id==id).select(db.function.ALL).first()
...
if functions.image:
image=db((db.bedrijfimagelink.bedrijf_id==id).select(db.imagelink.link).first()
if functions.text:
text=db(db.hptext.bedrijf_id==id).select(db.hptext.tekst).first()
return dict(..,image=image,text=text)
View:
div id=component
{{if image:}}
div id=banner style=text-align:center; height: 120px;
{{=IMG(_src=URL('static','init/images/banners/%s' % image.link),
_width=696px, _height=120px)}}
/div !-- banner --
{{pass}}
{{if text:}}
div class=oneColLayout
div style=margin: 24px 36px 0px 36px

/div !-- oneColLayout --
{{pass}}
/div !-- component --
...
div id= footer
{{=A('Lesrooster',callback=URL('timetable','timetable',args=[company.id]),target='component')}}
/div !-- footer --
Which generates the following link:
a onclick=ajax('ini/timetable/timetable/283',[],'component');return
false;href=#nullLesrooster/a
.. and address in the browser:
http://127.0.0.1:8000/init/locator/businesscard/283#null
... but doesn;t work either.
The problem with Cliff's solution (and all the examples at w3c) is
that the image and text are part of the first page, I cannot have the
vistor click a button to display the image and text.
I hope there is a way to get this to work ..

[web2py] SQLTABLE param headers=None bug - Web2py 1.99.2 (2011-09-26 06:55:33) stable
Hi
I think I found a bug with the headers with the above version, which
when headers=None generates a unsubscriptable error at line 2061:
if isinstance(headers[colname],dict):
This error can be fixed by the following changes added to line 1966 of
sqlhtml.py:
if not headers is None:
for c in columns:#new implement dict
if isinstance(headers.get(c, c), dict):
coldict = headers.get(c, c)
attrcol = dict()
if coldict['width']!=:
attrcol.update(_width=coldict['width'])
if coldict['class']!=:
attrcol.update(_class=coldict['class'])
row.append(TH(coldict['label'],**attrcol))
elif orderby:
row.append(TH(A(headers.get(c, c),

[web2py] Re: Nested functions problem?
The timetable link now works:

I have no idea why it didn't work ... So I am left with the problem of
loading the image and text the first time the locator/businesscard
page opens.

Maybe these are just typos, but looks like you've got an extra ( at the
beginning, and your select is coming from a different table than the query.
div id=component
{{=LOAD('locator','imagetext.load',args=283,ajax=True,target='component')}}
/div
No, don't put the LOAD helper inside a div. The LOAD helper creates its own
div with the id of the 'target' argument. The above will create a div with
id='component' inside another div with id='component' (which isn't allowed).
Also, whenever a component fails to load properly, always check to make
sure the action itself is returning something -- you can do that by going
directly to the URL of the component: /yourapp/locator/imagetext.load
div id= footer
{{=A('Lesrooster',callback=URL('timetable','timetable',args=[company.id]),target='component')}}
/div !-- footer --
Which generates the following link:
a onclick=ajax('ini/timetable/timetable/283',[],'component');return
false;href=#nullLesrooster/a
.. and address in the browser:
http://127.0.0.1:8000/init/locator/businesscard/283#null
Hmm, does the link really have no space between the end of the onclick and
the href (i.e., ...false;href)? If so, see if you can hand code that link
and add a space. If that's the issue, there may be a bug in the A() helper.

[web2py] Re: list of usernames
This is probably the easiest way to go. You could use a computed field, but
then if you want the computed field to appear in an update form, you have
to explicitly list it (along with all fields you want to appear). Note, if
you instead used request.vars.to to set the field default, that wouldn't
present any danger in terms of the contents of request.vars.to not being
validated, because you're only using the length of request.vars.to. It
would only be an issue if the validation of request.vars.to could result in
it passing validation but its length changing as a result of that.

You probably have some CSS or Javascript somewhere that is telling the
browser to display the URL for links in parentheses after the link text.
Something like this:

[web2py] Re: Nested functions problem?
Hi Anthony,
Maybe these are just typos, but looks like you've got an extra ( at the
beginning, and your select is coming from a different table than the query.
My bad, I stripped the query because it's much longer, and the entire
query isn't needed to get the picture.
This:
{{=LOAD('locator','imagetext.load',args=company.id,ajax=True,target='component')}}
so, without the div id=component/div, results in weird
behaviour. When I first visit the page, the div just displays
Loading..., when I click the lesrooster link, the image link and the
text display as is:
image:link: imagename.png
text:text: h4Texttextext/h4 ...
.. and when I click the lesrooster link again, the timetable displays.
Also, whenever a component fails to load properly, always check to make
sure the action itself is returning something -- you can do that by going
directly to the URL of the component: /yourapp/locator/imagetext.load
http://127.0.0.1:8000/init/locator/imagetext.load/283
displays:
image:link: imagename.png
text:text: h4Texttextext/h4 ...
http://127.0.0.1:8000/init/locator/imagetext/283
displays:
image:link: imagename.png
text:text: h4Texttextext/h4 ...
.. but in the generic view.
div id= footer
{{=A('Lesrooster',callback=URL('timetable','timetable',args=[company.id]),target='component')}}
/div !-- footer --
This works alright now.
I am stuck getting the image and text bit to work.
When I put a imagetext link on the page:
{{=A('Imagetext',callback=URL('imagetext',args=[company.id]),target='component')}}
... and put these back in the view: div id=component/div
The business card is being displayed correctly. But I cannot have
visitors click a link to display the image and text.
is there another way to fix this?
Kind regards,
Annet.

[web2py] Re: list of usernames
Thank you Anthony !
Is the length len always defined in Python ?
I couldn't find much tools in the documentation to query lists of
references apart from the contains operator.
For example, let's have the following message table :
id / to / status
1 / steve,jimmy / 0,2
2 / john,julia / 1,2
3 / julia,peggy / 0,1
I want to get the rows where Julia is in to and where her status
is 0 (in this particular case, that is row n°3).
With the contains operator I only know how to get the rows where
Julia is in to (that is row n°2 and n°3).
Should I write raw SQL ?

I will need to exclusively modify the variable status on other

true ?
So I decided to try an onvalidation function and I ended up with :
def status(form):
form.vars.status = [0]*len(form.vars.to)
def write():
form = SQLFORM(db.message)
if form.accepts(request.vars, session, onvalidation=status):
response.flash = 'Got it'
It seems to work.
Is it ok ? If I have understood correctly, onvalidation is called
after validation and before insert. Like this I am sure
forms.vars.to does not contain anything fishy or dangerous.

All this works very nicely.
Maybe the default format for auth_user should also be documented.
Let's say I have the following table :
db.define_table('message',
Field('to', 'list:reference auth_user'),
Field('status', 'list:integer'))
I want status to be a list of 0 as long as to, but
db.message.status.default = [0]*len(db.message.to.default) does not
work.
db.message.to.default represents the default value for the 'to' field
(which
you have not set), not the actually values being inserted. Anyway, I
don't
think the default for one field can reference the values of another.
There are a few other options. You could use a computed field (though by
default that won't display in a form, if you need that). If
inserts/updates
will always be handled via form submissions, you could us a form
onvalidation function or a custom validator. You could also just do
default=[0]*len(request.vars.to), since upon form submission, the
values
submitted to the 'to' field will be stored in request.vars.to (note,
the
values stored in request.vars will be the unvalidated values). See here

[web2py] curious DAL timeout issue
I'm a recent fan of web2py, having adopted it for some major
institutional projects in global agriculture. So far, so good - very
happy - but I have a recurring curious low level database error which
I'm not sure how to fix.
I've already tried trapping my web2py data model in a try... except
block, inside a loop to retry the database connection (about 20 times,
or so I think), but this doesn't seem to help. The database
connection often works... it is just that when the MySQL connection is
idle for too long, or when a fresh connection is requested for a new
user session, something fails... DAL doesn't handle it.
Here's the background: I'm running web2py in an NGINX server via uwsgi
(which generally works fine - configured based on good advice online).
However, this server runs within an Amazon Web Services (AWS) EC2
server and accesses a MySQL instance running non-locally as a AWS
Relational Database (RDB) server.
I'm using a DAL pool_size of 10.
Here's the error message:
Operational Error: (2013, 'Lost connection to MySQL server during
query')
Traceback (most recent call last):
File /opt/web2py/gluon/main.py, line 506, in wsgibase

I hope someone can suggest something here. Do I need to tweak some
MySQL client parameter, or does someone have some advice about Amazon
RDB usage practicalities in such a situation?

Are you talking about the timetable link? How is that returning the

Also, below you noted that visiting the imagetext.load URL directly yields
that same content, so it looks like the problem is the imagetext.load view
isn't returning what you want, so you'll have to debug that function and
view.
I am stuck getting the image and text bit to work.

If you're using components, rather than using the callback/target arguments
to A(), use the regular _href argument and the cid argument -- that will
load the _href as a component into the div identified by cid (make sure the
URL uses the .load extension if you've got a .load view for timetable).
See
https://docs.google.com/spreadsheet/ccc?key=0Ajy6-Ewiiuo6dGlqckdOUnB5Yl9OSmd0bV9fN0lvSlE.
The initial LOAD should automatically load the imagetext, and clicking the
link should replace that with the timetable component.
If you're still having trouble, I suggest you post a minimal application
that reproduces your problem.

And why the object could not be a query that can return a list of records having the state you are looking for?? Richard On Mon, Oct 24, 2011 at 8:25 PM, Triquetra trique...@triquetradevelopment.com wrote: No, I don't think this helps, unless I'm misunderstanding something (which is possible). When using auth.add_permission(group_id, 'name', 'object', record_id) the CRUD permissions are only enforced if the object is a table (according to the book). So, even assuming one could pass a column as the object (to enable field based access control), the web2py access system will not automatically enforce CRUD permissions on this object (like it would with tables or records). This level of access control would require additional manual enforcement in the controllers. This doesn't help with state based permissions either. The issue here is that permissions may change depending upon the state of the object. Workflows are a good example. If A is in group author and E is in group editor, a workflow may demand that A has full CRUD rights until the article is submitted for editing, then A only has read rights over the SAME record and editor group gets read and update rights only after submission of the article for editing. Same record, same groups, same users -- different permissions based on the state of the record (which could be indicated by the content of a field). On Friday, October 21, 2011 3:54:26 PM UTC-4, Triquetra wrote: I'd like to see web2py's access control beefed up (thus permitting easy development of workflows, among other things). Specifically, the current web2py RBAC has two levels of granularity: table and record (row). This should be extended to include field(column), type(controller), and context(state). auth.add_permission(group_id, 'name', 'object', record_id) In the above, 'object' can be any user-defined object, not just a DB table (record_id is only relevant if the object is a table). Does that help? Although the type(controller) access control is currently implemented via decorators in web2py, this is restricted to coders. You don't have to use decorators. You can directly check for permissions via auth.has_membership() and auth.has_permission().

According to the doc it would need something like this to work: auth.has_permission(group_id, 'read', 'table123', field123 == 'something') This would lead to check if a user as the permission read on table123 when field123 has the value something... It would be great if it is possible...

Richard On Mon, Oct 24, 2011 at 8:25 PM, Triquetra trique...@triquetradevelopment.com wrote: No, I don't think this helps, unless I'm misunderstanding something (which is possible). When using auth.add_permission(group_id, 'name', 'object', record_id) the CRUD permissions are only enforced if the object is a table (according to the book). So, even assuming one could pass a column as the object (to enable field based access control), the web2py access system will not automatically enforce CRUD permissions on this object (like it would with tables or records). This level of access control would require additional manual enforcement in the controllers. This doesn't help with state based permissions either. The issue here is that permissions may change depending upon the state of the object. Workflows are a good example. If A is in group author and E is in group editor, a workflow may demand that A has full CRUD rights until the article is submitted for editing, then A only has read rights over the SAME record and editor group gets read and update rights only after submission of the article for editing. Same record, same groups, same users -- different permissions based on the state of the record (which could be indicated by the content of a field). On Friday, October 21, 2011 3:54:26 PM UTC-4, Triquetra wrote: I'd like to see web2py's access control beefed up (thus permitting easy development of workflows, among other things). Specifically, the current web2py RBAC has two levels of granularity: table and record (row). This should be extended to include field(column), type(controller), and context(state). auth.add_permission(group_id, 'name', 'object', record_id) In the above, 'object' can be any user-defined object, not just a DB table (record_id is only relevant if the object is a table). Does that help? Although the type(controller) access control is currently implemented via decorators in web2py, this is restricted to coders. You don't have to use decorators. You can directly check for permissions via auth.has_membership() and auth.has_permission().

[web2py] Domain Masking and Internet Explorer

I used domain forwarding with masking on stressrelief.drsommers.com to point to http://goodsexnetwork.com/stressrelief. On Internet Explorer, this hinders the login function -- when you enter username/ password, the browser simply throws you back to the login page (with no error message).

causes the error, for some reason when there is an argument in that

[web2py] Re: sqlform.grid
Thanks Bruno. Adding in the css for grid actually spoilt things. I have managed to get a good looking grid for CDs with graphics using smartform.grid, but the base.css messes this up. See ukjazz.net/albums for a demo. This is a slightly confusing table as the column headings our out of place, however I need them there for sorting. I tried solidtable and this did not help. I think what I have got is probably as good as I am going to be able to use whilst still having the other benefits of using a table. By using the css for the paginator I sorted out the page number along the bottom.

[web2py] Re: list of usernames
That's what I was thinking. list: type fields are good if you just need to store a list of things associated with a given record and retrieve the list when the record is retrieved, but they aren't necessarily easy or efficient for querying the data (depending on the application). If you really want to stick with the list: fields, I suppose you could do a select to get the Julia records, and then use some Python code to further filter the records based on status. You might also be able to create either a computed or virtual field that concatenates name and status into a new list, and query that. Depending on how many records you're dealing with, though, it might be more efficient to go with a more normalized data structure.

The way your domain masking works is that a frameset is set up at the masking URL (stressrelief.co.nr), and your actual site is placed inside a frame. In that case, apparently IE doesn't pass the session cookie back to your application. See http://adamyoung.net/IE-Blocking-iFrame-Cookies. It's probably not a good idea to use domain masking anyway (the address bar won't show any of your internal URLs -- nothing can be bookmarked).
