[web2py] Re: Uploading images
Hello Alan, Thank you very much for your answer. Finally, based on your note ( ... renames uploaded files (to prevent directory traversal attacks) ...), in the difficulty of the changes, and taking into account that the rename is not very necessary in fact, I've decided not to change the name of the uploaded files. Now I upload and retrieve the images with the code Massimo gave me and the download() function you say. Thank you very much for the help!

[web2py] subforms / formsets / form cloning imprementation
Hello everybody! I'm quite new to Python and web2py, but I consumed all of web2py's wonderful documentation at the last few days and I'm quite amazed at this wonderful framework. But there's a feature that I need that I couldn't find a way to easily implement it. The application that I'm developing requires extensive use of form cloning within a single web page, done dynamically at the client side. I'm not really sure how to call this technique, so I found a bit hard to find information regarding this at this mailing list's archive. What I want to accomplish can be easily understood viewing the screenshots from this tool: http://www.mdelrosso.com/sheepit/ I already have my own (ugly) jquery code to create the forms dynamically, and of course I could validate it manually on web2py's side, but I was looking into an easier implementation using something like FORM or SQLFORM. Like I said, I'm very new to web2py and python, and I have no idea how django works, but I think I need to accomplish something similar to this: https://docs.djangoproject.com/en/dev/topics/forms/formsets/ I tried searching this mailing list archive and I found a couple of discussions from people trying to do the same thing, but I didn't find a solution. https://groups.google.com/forum/#!topic/web2py/ssaSj6v9Wu8/discussion https://groups.google.com/d/topic/web2py/UK8NZ1VMlNk/discussion But these are threads from 2011 There's also this guy asking something similar a couple of months ago: https://groups.google.com/d/topic/web2py/IPMz4FylT2k/discussion and http://stackoverflow.com/questions/13215902/web2py-possible-to-submit-multiple-forms-with-a-single-submit-button/13215926#13215926 but the solution presented didn't seem very elegant. Anyway, I would really appreciate any help on this. Thanks, Henrique. --

[web2py] self join on postgres
Hi all, I've problems on defining self join queries on postgres, the query,
works on sqlite, is defined as follows:

end = db.record.with_alias('end')
query = ((start.station_id == 11)

The table is:

[web2py] Re: cpdb errors
hum... you should just remove the quotes around the connection strings
(options -y and -Y) since they are already strings when passed in.
Otherwise, argparse will do this: ' sqlite://storage.sqlite' and then
dal will not be able to open the DB.
So, no quotes, should fix the problem.
-y sqlite://storage.sqlite -Y postgres://postgres:password@
localhost:5432/db_target
I haven't run this in a long time, but just tried it and it ran just fine.
Note, the -d option is pointing to a recent dal.py which i simply dumped
in the /Users/mart directory.
I don't have a windows machine, but I think i can find one at work tomorrow
and see if it behaves differently.
guimauve:src mart$ python cpdb.py -f db_storage/cvs -d /Users/mart -y
sqlite://auth_storage.sqlite -Y sqlite://storage2.sqlite -F db_storage/cvs_2
gluon path not found
creating tables...
exporting data...
importing data...
done!
Attention: do not run this program again or you end up with duplicate
records
guimauve:src mart$
BTW - @ user backseat: Perhaps a little late, but I just noticed now...
same goes for you, the quotes need to be removed.
If the manual says sqlite://storage.sqlite for options -y and -Y, then
that should be simply be corrected.
Hope it helps,
Mart

the first message is expected because of this import:

It wants to assume that that gluon is already loaded as part of the
web2py environment (or as part of some other environment, like Aptana for
example) and that you already have /gluon in your path (maybe even hard
coded). If the gluon path is not set, well, you will get that gluon path
not found message and the -d option will be expected. Because the -d
option is expecting a *relative* path, your cmd line args will look
different depending on the environment in which you are running the script.
Hum... I guess being relative is relative ;)
So, as an example, if you were to run this cmd from a simple bash shell
(outside of any dev environment, or outside of a web2py context), you would
simply cd and drill down into .../blabla/.../web2py/scripts/. In which
case, your -d option would look like this:
-d ../gluon.
I just did this, and it all worked fine:
macMart:Documents mart$ cd Aptana\ Studio\

sqlite://storage.sqlite -Y sqlite://storage2.sqlite -F ../../db_storage2

[web2py] registration issue with web2py 2.3.2
After upgrading to 2.3.2, my custom user registration breaks. I have
auth_user password encoded as follows in my user's model:
...
Field('password', 'password',
readable=False,
label=T('Password'),
requires=[CRYPT(), IS_LENGTH(512, 6)],
),
...
During registration, I create the register_form like so in my controller:
register_form = SQLFORM.factory(
...
db.auth_user.password,
Field('password2', 'password',
label=T(Verify password'),
requires=db.auth_user.password.requires,
),
...
)
During form acceptance, the form is validated by this:
def validate_registration(form):
...
if form.vars.password != form.vars.password2:
form.errors.password = form.errors.password2 = T(
'Passwords do not match')
...
return form
The problem is the passwords aren't the same. I'm assuming the problem is
the requires=CRYPT(), which actually encrypts the password twice, producing
two different results for password and password2. How would I get CRYPT()
to product the same result for both passwords? Do I need to pass in the
hmac_key or salt? Or not run CRYPT() at all?

I don't see it as an issue, but I'd consider merging those css files into one, to reduce the amount of requests that need to be made.

[web2py] Help integrating s-cubism uploadify widget
Hi I am having problems integrating this plugin
http://dev.s-cubism.com/plugin_uploadify_widget in to my form.
In my Models.py I have
from plugin_uploadify_widget import (
uploadify_widget, IS_UPLOADIFY_IMAGE, IS_UPLOADIFY_FILENAME,
IS_UPLOADIFY_LENGTH
)
db.define_table('video',
Field('userinfo', db.auth_user, default=auth.user_id, readable=False,
writable=False),
Field('title', length=64, requires = IS_NOT_EMPTY()),
Field('trailer', 'upload', IS_LENGTH(550*1024*1024,
error_message='filesize exceeds 550 megabytes'), autodelete=True),
Field('video', 'upload', IS_LENGTH(550*1024*1024,
error_message='filesize exceeds 550 megabytes'), autodelete=True),
Field('created_on','datetime',default=datetime.datetime.today(),
writable=False,readable=False))
The core
##
# Inject the uploadify widget
# The requires needs custom validators.
db.video.trailer.widget = uploadify_widget
db.video.trailer.requires = IS_EMPTY_OR(IS_UPLOADIFY_LENGTH(3012024))
# Inject the another uploadify widget with different requires
db.video.video.widget = uploadify_widget
db.video.video.requires = IS_UPLOADIFY_LENGTH(3012240, 1)
But I am not sure what to do from here. How do I get the plugin to replace
the regular form area for uploads. My controller consists of this
@auth.requires_membership('admin')
def video():
videos = db(db.video.id0).select()
form = SQLFORM(db.video)
if form.accepts(request,session):
response.flash = 'You have successfully created a new video'
return dict(form=form,videos=videos)
elif form.errors:
response.flash = 'Please correct the highlighted fields'
return dict(form=form,videos=videos)
#form = LOAD('plugin_uploadify_widget', args='ajax', ajax=True)
return dict(form=form,videos=videos)
Any ideas?

[web2py] Re: self join on postgres
Hi Niphlod, yes it solved the problem.
Now I have an other problem, I need to make a self left join, but limited
to 1 match only. Namely, I've just need to make the join only for the first
matching row. I've tried something like:
rows = db( query ).select(start.gathered_on,start.mac,start.id,
end.gathered_on, end.mac, end.id,
start.gathered_on.epoch(),
end.gathered_on.epoch(),
orderby=start.gathered_on.epoch(),
left= start.on(start.mac == end.mac),
groupby=start.id,
cacheable = True)
This actually works on sqlite but on postgres failed because on postgres
you can group only onto the field expressed in the select. Moreover, even
if on sqlite it works, It select the wrong rows.
Online I have found this post:
http://archives.postgresql.org/pgsql-novice/2011-01/msg00069.php
and now I am trying to understand how to define a sub_select with the
limitby=1 to carry out the left join.
Any idea ?

Paolo

using field.represent or the new filter_out parameter ... docs aren't there

However, for computations like MARKMIN, the better choice is to store in
another computed field the result, so you don't spend cpu cycles on
rendering over and over the same thing every time.

[web2py] Re: self join on postgres
If I understand correctly the problem it's a matter of using windowing
functions, that are not available on all db engines and far too complicated
to expose a consistent api by the DAL.
Picking out the first match only doesn't quite explain what you need in
detail (maybe it can be worked out without windowing functions in a
particular case) can you please make an example of real data to start
with and what you want the resultset to return ?

Thanks. Concerning saving the computed result, would that be another field
which saves the post in HTML and using that field when rendering pages? I
wouldn't think rendering markmin to HTML would be of an consequence on CPU
load. I think the complication involved in storing the same data in two
formats in the database as well as the database size would be something I'd
want to avoid.

[web2py] Re: Is it possible to define how a field is rendered in the DB model?
represent only affects how the value is displayed in forms (including read-only forms) and the grid, whereas filter_out is applied when the database result is parsed into the Rows object, so it affects everywhere the value might be used or displayed. represent is often used with reference fields, which typically makes more sense than using filter_out because although you may want to display the reference field differently, you probably still want to retain the original id value as well (filter_out replaces the original value with the transformed value).

[web2py] Re: Is it possible to define how a field is rendered in the DB model?
it's completely up to you. Try to do some tests though. Unless you're
storing millions of markmin fragments, having a row holding 0,2 KB of
markmin source or 0,2+0,4 of markmin source + html at the end of the day
means adding few megs up.
On the other end, a reddited blog post having to render the markmin to 1M
users may speed down your app a bit.
On the far end, caching the html of the page in ram or in memcache or in
redis in the controller will be the best possible solution but again,
it depends on the app.

Thanks. Concerning saving the computed result, would that be another field
which saves the post in HTML and using that field when rendering pages? I
wouldn't think rendering markmin to HTML would be of an consequence on CPU
load. I think the complication involved in storing the same data in two
formats in the database as well as the database size would be something I'd
want to avoid.

However, for computations like MARKMIN, the better choice is to store
in another computed field the result, so you don't spend cpu cycles on
rendering over and over the same thing every time.

[web2py] Re: self join on postgres
after a full day at work I may lack the usual fantasy, but what you're trying to do can't be even achieved by a relatively simple windowed function What you're trying to do is recursing. way out of DAL reach (if you want to do it in a single query) Trying to explain better Real data helps. For every station_id record with the same mac address you want to find the min gathered_on record from the same table (with another station_id) and subtract it for every next possible match. One thing is requiring 2013-01-21 11:23:35;a;127167;2013-01-21 11:23:45;a;127168 2013-01-21 11:23:00;a;127169;2013-01-21 11:23:45;a;127168 That can be accomplished by something like this select * from ( selectstart_point.gathered_on,start_point.mac,start_point.id, end_point.gathered_on,end_point.mac,end_point.id, row_number() over (partition by start_point.id order by end_point. gathered_on) as filter_field from record as start_point inner join record as end_point on start_point.mac = end_point.mac and start_point.gathered_on = end_point.gathered_on where start_point.station_id = 13 and end_point.station_id = 14 ) as q where q.filter_field = 1 because for the record 127167 the next record with another station_id is 127168, but then for the 127169 you don't want the 127168, you want 127170 because 127168 has been booked before by 127169. Honestly, (beware of the lack of fantasy :P) I'd do a loop in python instead of using recursing in the db itself unless you have zillions of windows (i.e. you have 1000 station_id = 13 and 1000 station_id = 14, and 1000 distinct station_id), just because it's more readable than what it would be needed in raw sql --

[web2py] Re: cpdb errors
Hi Simon, Yes, that looks like a CSV error message. Possibly, the CSV format is missing something expected... I would say that the problem occurs when converting from CSV. I would suggest that you take a look at Massimo's CSVStudio @https://code.google.com/p/csvstudio/ i think it has something that will convert your CSV cols and rows to a model by generating db.define_table(...) Never the less, I will keep looking and see what turns up. I ran these on either a Linux flavour or MacOS... Unfortunately, I wasn't able to find a usable windows box today. I didn't run this against entire web2py filesets, I simply pointed to a location on my laptop, dumped different versions of dal.py there replacing them with what ever version I found - some old some more recent)... But they all worked. I hope this helps, Mart :) On Monday, January 7, 2013 4:05:40 PM UTC-8, Simon Ashley wrote: Thanks Mart, That's sort of fixed it, but starting to get additional issues with the auth tables. https://lh4.googleusercontent.com/-HAmuqaTtnd0/UOtg3XU7NHI/AG8/LpeAt3Dm15w/s1600/copy+database2.png Think have seen this before with csv imports and have gotten around by deleting suspect areas from the import source files.

[web2py] Re: subforms / formsets / form cloning imprementation
i have an (untested) idea...plugging together a few things i have used before - you could create templates of field sets using handlebars: http://handlebarsjs.com/ then you can via JS add them to the page based on user interaction. - you can use hidden fields to provide some meta data on the form. - remembering that in your controller you define your SQLFORM *before* you process it, you could check for the presence of your hidden fields in request.vars, and based on their values initialize your SQLFORM to match the sub-forms that were added to the form. then when you call .process it will check all those fields as well. i don't know if that is a great idea or not (we recently solved this problem at my workplace but i think ended up using handlebars and manual form processing)it's a thought we considered and still might try! christian On Sunday, January 6, 2013 11:02:01 PM UTC-8, Henrique Pantarotto wrote: Hello everybody!

[web2py] Re: registration issue with web2py 2.3.2 [CLOSED]
Alright, I think I got this figured out. Issue is 2-fold. First, IS_LENGTH
validator is executed after CRYPT() runs, so it fails. Moving IS_LENGTH to
the array position before CRYPT() and changing password2 validator to
... requires=IS_EQUAL_TO(request.vars.password) ... causes things to work.

...
During registration, I create the register_form like so in my controller:
register_form = SQLFORM.factory(
...
db.auth_user.password,
Field('password2', 'password',
label=T(Verify password'),
requires=db.auth_user.password.requires,

During form acceptance, the form is validated by this:
def validate_registration(form):
...
if form.vars.password != form.vars.password2:
form.errors.password = form.errors.password2 = T(
'Passwords do not match')
...
return form
The problem is the passwords aren't the same. I'm assuming the problem is
the requires=CRYPT(), which actually encrypts the password twice, producing
two different results for password and password2. How would I get CRYPT()
to product the same result for both passwords? Do I need to pass in the
hmac_key or salt? Or not run CRYPT() at all?
