[web2py] Re: An enhanced BEAUTIFY class
This is a better keyfilter for the new BEAUTIFY than the one I
provided as it allows a key to be an empty string.
keyfilter=lambda key=' '.join([x.capitalize() for x in
key[2:].split('_')]) if key[1:2]=='_' else key
I have updated a web2py slice with information about using the new
BEAUTIFY at http://www.web2pyslices.com/main/slices/take_slice/58

Thanks Massimo
The keyfilter example you provided does not work but this one does
with the current BEAUTIFY in the trunk
keyfilter=lambda key=' '.join([x.capitalize() for x in
key[2:].split('_')]) if key[1]=='_' else key
A typical view file is now
{{extend 'layout.html'}}

You try to achieve two things:
1) As you say if the key starts with a_, this is removed. This is a
trick to make sure elements are sorted as you like them.
2) You capitalize the words and replace _ with spaces.
I think these are wrong solution to the problem. Look into trunk. The
new BEAUTIFY now takes two optional named arguments: sorted,
keyfilter.
You can do what you want with
BEAUTIFY(dict(),keyfilter=lambda key: ' '.join([x.capitalize() for
x in key.split('_')[1:]) if key[1:2]=='_' else key)

There is choice. In the four line example code I posted (which is from
a web2py slice) the keys are only changed if the second character is
an underscore.
I accept there is little enthusiasm. It is ironic because I think
there is potential to generalise an approach (such as with functional
hooks as mentioned) and show the framework working in a way that
would generate more interest from the Python community (no web2py at
PyCon). If there was a suitable hook then there would be no need to
modify the BEAUTIFY class in the web2py core.

I don't have the skills or time to make the site pretty. If I start to

What I would really prefer in web2py is a hook in BEAUTIFY and other
helpers so I could bypass them and not have my changes overridden
every time I do an upgrade. Even a hook in a low level inherited base
class would be enough, if using the hook would enable the name of the
helper to be determined and to override the helper. However I reckon
this is too much to ask!

Hi John,

Beautify is only a prototyping testing thing for most so it's
making
something prettier that no one will see. But it's still better, so
why
not? +1

People say there is some magic in web2py.
Here is some real magic now in trunk that I am sure you have never
seen.
Caveats:
0) requires latest trunk (bzr 1603, hg 175:e42b559254f6)
1) this is an experiment, not sure it is a good idea
2) this is the first function in web2py that REQUIRES jQuery
3) works but I am not yet convinced it should stay there
4) even if it stays, I am sure the API should stay
Example:
### assume this model
db.define_table('target',Field('name'))
if not db(db.target.id0).count():
db.target.insert(name=Klingon)
db.target.insert(name=Romulans)
db.target.insert(name=Borg)
db.target.insert(name=Borg2)
db.define_table('photon_torpedo',Field('target',db.target))
### assume this action in controller default.py
def launch():
db.photon_torpedo.target.represent=lambda target: target.name
return dict(new_torpedo=crud.create(db.photon_torpedo),
launched_torpedos=db().select(db.photon_torpedo.ALL))
So far nothing new.
Now append to the model or insert at top of controller the following:
from gluon.sqlhtml importAutocompleteWidget
db.photon_torpedo.target.widget=AutocompleteWidget(request,db.target.name,db.target.id)
No need to define any callback action

[web2py] Re: session.flash not displayed anymore
I just figured out that it only happens if I do a redirect to the page
from which the controller was called.
It happens like this:
- A link on a page home is clicked to access a page book but in
the book controller because some conditions are not met, I set a
message using session.flash('message') and do a redirect to home. It
goes to home but no message is displayed.
On the other hand, if the redirect is set to a page different from
home, then the message is displayed.
What should I do? Is the redirect not appropriate in the case we go
back to the calling page?

[web2py] Re: how to display date and time nicely?
IMHO, the example's code is good, but not cool enough to be put in the
book. Every programmer saw those ordinary if...elif...elif...else
cliche in their first program language book before. People can
probably write their own if...elif...else in less time, than STFW or
RTFM to find our prettydate().
So, we need some extra flavor to compensate the time a guy spent to
find our prettydate(). How about making it i18n-friendly? Something
like this.
class PrettyDate(object):
def __init__(self,T):
self.T=T #
def __call__(self, d):
dt = datetime.now() - d
if dt.days = 2*365:
return self.T('%d years ago') % int(dt.days / 365)
elif ...:
..
Then, in the model we can initialize an instance by:
prettydate = PrettyDate(T)
In controller we can do:
prettydate(d)
Of course developers need to localize their own language strings in
their own environment.

Caveats:
0) requires latest trunk (bzr 1603, hg 175:e42b559254f6)
1) this is an experiment, not sure it is a good idea

[web2py] Re: How to deploy my first app
Brian, Thank you for your detailed instructions. I managed to get stunnel working, though it is a lot more complicated than I thought originally. On the windows server, the stunnel.conf file is setup as server mode and redirect port 8443 to 8000. On the client side, I also have to set up another stunnel as client mode and redirect 127.0.0.1:80 to 192.168.1.11 - server's IP address. As this server will be facing public, I cannot expect people to set up stunnel in their machine in order to access my website. I was expecting a tool which runs on the server side to do port redirection, and then when I type in http://server_ip:8443 from another machine, it will route me to my target app. (note: I did NOT set up any SSL certificate to get stunnel working) Also with stunnel, I still cannot access the target app without entering the admin password, I cannot find any response.menu_auth to remove. I also have another mac which I tried to set up stunnel, but when I run sudo stunnel3 I got the following error: anyone familiar with mac can give some tips on how to solve this: inetd mode must define a remote host or an executable Cheers Al On Feb 12, 8:09 am, Brian M bmere...@gmail.com wrote: Al, You'd want to get rid of the edit menu when you Go Live that's just there as a convenience while you're creating things. Just use this (or remove response.menu_edit from menu.py which does it once for all): response.menu_edit = None If you don't want auth menu either do response.menu_auth = None If you want to use the built-in server and be able to access on both port 80 and port 443 (SSL) without running two web2py server instances you could perhaps use a tunnel program likestunnel(www.stunnel.org). Set it up to listen on port 443 (or really any port) and re-direct to localhost:80. This way you should be able to get at admin and tickets - as far as web2py is concerned you're accessing from the local machine so tickets should work, but because it's tunneled it's also secured as it goes to your remote computer. To get the general user to automatically go tohttp://myserver/myfirstapp when they type inhttp://myserver/you can either work with routes or just take the lazy route and replace the welcome app's default/index with a redirect to whatever the home page of myfirstapp is. Of course this will break the welcome app, but do you really want/need it when deployed anyway? #in the Welcome application's default.py controller def index(): redirect(URL(a='myfirstapp', c='default', f='index')) Setting up web2py as a Windows Service is easy enough:http://www.web2py.com/AlterEgo/default/show/77 ~Brian On Feb 11, 9:54 am, Al albertsec...@gmail.com wrote: Thank you for your input.

[web2py] website not working
Hi guys! I've been trying to access the web2py website for the last couple of days, with very little success. Most of the time I get a The connection was reset message, and if somehow I get a connection, the navigation is very slow.

[web2py] Re: How much memory does web2py need on Unix
Well, I gave this a try, and ended up with 404 errors.
fcgihandler.py suggests adding to lighttpd.conf
server.error-handler-404 = '/test.fcgi'
This does not help, nor does
server.error-handler-404 = /error-handler.fcgi
( There no files on my system named *.fcgi, so I do not see how this
could help )
I suspect my problem might be with this line
$HTTP[host] =~ (^|\.)example\.com$ {
Since I am running on a VPS I only have an IP address.
I tried
$HTTP[host] == 100.101.102.103 {
and
$HTTP[remoteip] == 100.101.102.103 {
and
#SERVER[socket] == 100.101.102.103 {
and some other variations on this, but nothing helps.

[web2py] Long running tasks queue
Hello, I have a screen scraper that I would like to call from web2py. I currently have a controller method that calls it and updates data in the DAL. The problem is, the number of users of this app is growing quickly. I need to queue the updates so I don't overwhelm the server that it is scraping. I would like a cron script to fire off daily and set the queue in motion. I would like to limit the queue to update 5 users or so per minute.

[web2py] Re: session.flash not displayed anymore
Thank you Massimo,
I have tried it but nothing seems to have changed.
Here is what I have:
-
def firstpage():
return dict()
def secondpage():
session.flash=response.flash
session.flash=T('You cannot view the secondpage, you are back to
the firstpage!')
redirect(URL(r=request,f='firstpage'))
return dict()
and in firstpage.html:
{{=A('Link to secondpage',_href=URL(r=request,f='secondpage'))}}
-
The flash message is not displeayed though.
But if I change the redirect to another page, let us say 'pagethree',
then the flash message is displayed when 'pagethree' is displayed..

Usually this problem is caused by double redirect. Try add

I just figured out that it only happens if I do a redirect to the page

It happens like this:
- A link on a page home is clicked to access a page book but in
the book controller because some conditions are not met, I set a
message using session.flash('message') and do a redirect to home. It
goes to home but no message is displayed.
On the other hand, if the redirect is set to a page different from
home, then the message is displayed.
What should I do? Is the redirect not appropriate in the case we go
back to the calling page?

something like this could be really nice for browsing the function

If you use a StringListProperty to store all the ngrams (eg: web2py,

[web2py] Re: routes for subdomain
Jon, you right. If the example.com and all *.example.com prefixed
domains are mapped to the same web2py app it shouldn't really matter
if the host is rewritten. But then you have to be careful and don't
use relative urls when linking between the prefixed and non-
prefixed parts.
The rules I proposed are still a bit incorrect, as the case of not
default/public and not prefixed controllers is not handled correctly.
And the proper out routing is only possible when all prefixes are
explicitly enlisted. Here is the doctest with extended rules:
http://pastebin.com/f3969be47.
PREFIXES = [dashboard, forum, tracker]
routes_in = (('.*:https?://([a-z]+)\.example\.com:.* /(.*)', r'/init/
\1/\2'),
('/([a-z]+)/(.*)', r'/init/\1/\2'),
('/(.*)', r'/init/public/\1'))
routes_out = (('/init/public/(.*)', r'/\1'),
('/init/('+'|'.join(PREFIXES)+')/(.*)', r'/\2'),
('/init/(.*)', r'/\1'))

[web2py] Limiting to a single process
I'm running a background database processing task, and I only want to
have ONE task running so I don't have to worry about race conditions.
What is the best way to do this?
I run this task from a cron @reboot. It runs this script:
while True:
time.sleep(10)
process_queue()
I'm worried that I might accidentally run two web2py processes at the
same time, each starting a cron job, and then I'd have two running and
mess up my data. So I want this script to check to see if another one
is currently running, and if so, to give up.
I considered making an entry in a database like
background_task_running = true, but how can I guarantee that it gets
set to false if my web2py crashes? I don't want to have to manually
reset that field all the time.
Is it best to see if this process is currently running on the machine,
with os.system('ps aux | grep background_work.py'), but this isn't
cross-platform, and won't work if the process is running on another
machine. Is there a way to check if another of these processes is
connected to the postgresql database?

[web2py] Re: How much memory does web2py need on Unix
Hi Raven
The name fcgihandler.py is just the name of a web2py start up file
passed to Python.
The name fcgihandler.py should not or need not appear anywhere in the
lightttpd.conf file, since there is no need to give lighttpd the
responsibility to start up web2py as an independent process.
What lighttpd needs to know is where the UNIX socket is that is
configured for use by web2py in fcgihandler.py. The name that
ligthttpd.conf uses to tell the rest of lighttpd.conf to use the UNIX

[web2py] Difficulty with a form
I have created a form using SQLForm. I am using a db query to select a single row from a db table, and I want to make changes to it. However, when I submit, some of the data disapears in the submit. This happens to also prevent the form from submitting as that data that disapears is very important. Here is what I have: DB table company with fields name and title DB table user with fields name and title, and a foreign key of company id When I use SQLForm(db.user, session.currentUserID) and submit this form, the company_id field is null, even though before I submitted the field in the DB has a 2 in it. Note that I have not actually generated the field in a view. So I imagine that any field that is not in the view is submitted as NULL. Is this a bug? I believe any field that you don't use in a view should just be re-submitted with the same data that was in the field before. Whats going on here? Why does the field go empty? Is there a way to manually set a value to the field before it submits? -- You received this message because you are subscribed to the Google Groups web2py-users group.

Re: [web2py] Re: How much memory does web2py need on Unix
I was reviewing this threadand wow! very nice explanation and presentation of playing video streaming via web2py. Many thanks John, your thoughts looks like very interesting. Alex El 14/02/2010 3:12, John Heenan escribió: Thanks for your comments also. Yes .flv and other video files will play with Lightttpd using normal media players, for example, using JW Player in kpax/static/ mediaplayer.swf . It is even possible to use players while the actual video file is hosted on another server to where the main site and player is hosted. It is really more of a browser issue unless seek based streaming is desired. The video files I host on http://www.zgus.com are on Amazon S3 servers because the traffic costs are lower this way and because VPS disk space usage is kept lower. In fact, as mentioned in http://groups.google.com/group/web2py/msg/e273fa31c779c44c , I think it would be a good idea to allow large uploaded files to automatically transferred across to other servers. Keeping large files on otherg severs is the 'enterprise way'. There is mature python infrastructure, s3cmd, to allow file transfer to Amazon S3 servers, as indicated in the link. There is another meaning for streaming which basically means being able to seek anywhere into the video file without downloading the entire file into the browser cache. Lighttpd supports this type of streaming 'out of the box'. Apache does not. YouTube uses Lighttpd and supports this type of streaming (provided the video file has the necessary meta data). Having a web server that supports seek based streaming is not enough. For this type of streaming a compliant media player is required and video files need to have meta data installed. There is a coherent presentation on this type of streaming, on what needs to be done to video files and a video example at http://flowplayer.org/plugins/streaming/pseudostreaming.html John Heenan On Feb 14, 1:44 am, mdipierromdipie...@cs.depaul.edu wrote: Very well done.

get install mod_wsgi on ubuntu 8.04.
Ubuntu still has a quite old mod_wsgi version in the main repository,
possibly even on mod_wsgi 1.X given you are using ancient ubuntu 8.04.
The latest mod_wsgi version is 3.1 and if can you should use that.
If you weren't using an ancient version of mod_wsgi I would have
suggested you change the configuration line:
WSGIDaemonProcess web2py user=www-data group=www-data
to:
WSGIDaemonProcess web2py user=www-data group=www-data display-name=%
{GROUP} maximum-requests=5000 inactivity-timeout=60
The 'display-name' option with that value will cause the process to be
listed in 'ps' output as '(wsgi:web2py)'. That way is easier to
identify separately from core Apache server processes. This option was
only added in mod_wsgi 2.0.
The 'maxiumum-requests' option would cause daemon process to be
shutdown and restarted after 5000 requests. That way if you do have a
problem with cache cleaning or Python object reference counting cycles
which cant be broken by the Python garbage collector, then you at
least throw everything away and start over again every so often.
The 'inactivity-timeout' option is another way of forcing a process
shutdown and restart to reclaim memory and start over. In this case if
no requests are received in 60 seconds since the last request and so
application is idle, it will shutdown and restart the process. This
option was only added in mod_wsgi 2.0.
To check which version of mod_wsgi is running you can look at the
startup messages for Apache, presuming ubuntu hasn't hacked the
startup message to disable display of Apache module information. The
message will be of the form:
Apache/2.2.2 (Unix) mod_wsgi/1.0 Python/2.3.5 configured
If you can't find that in main Apache error log from time when Apache
last restarted, then you will need to work out which version is
installed from the ubuntu packaging system.
Now that fixed the BEAUTIFY but the problem is no longer as severe as
before but I do see one process (the multi-threaded one) consume more
memory than everything else.
Which is the mod_wsgi daemon process which holds the web2py instance.
It will obviously be bigger, but if it keeps growing then you likely
have an issue with the application. There has never been any issue
with mod_wsgi which would see such memory growth.
If you were using mod_wsgi 2.X (preferably 2.5 or later), then those
options to WSGIDaemonProcess would at least allow it to recover itself
whil you sort out what the real problem is.

Look at process 6320. It is using way more memory than any other one.
Eventually it will fill the ram. Seems like a memory leak. Only one
process does it. I will it and another process takes his place.
What is going on?
I have never seen this problem before. Looks like a memory leak and
seems related to this:
http://www.paulstimesink.com/post/2005/05/21/memory-leak-in-apache/
Likely unrelated because for you it is affecting only one process.
For now I am following their suggestions and we'll see.
Presuming you are now running mod_wsgi, post your Apache configuration
snippet for how you set mod_wsgi up.
Specifically, confirm that you are using daemon mode? Also indicate
which version of mod_wsgi you are using.
If you have an incremental memory growth problem because of web2py,
there are various things one can do in mod_wsgi daemon mode
configuration to combat the issue until you work out the real cause.
So long as you are using daemon mode, that you are using prefork MPM
is not a big deal.

If you use a StringListProperty to store all the ngrams (eg: web2py,
web2p, web2, web, we, w) then it could match partial words.

startup messages for Apache, presuming ubuntu hasn't hacked the
startup message to disable display of Apache module information. The
message will be of the form:
Apache/2.2.2 (Unix) mod_wsgi/1.0 Python/2.3.5 configured
If you can't find that in main Apache error log from time when Apache
last restarted, then you will need to work out which version is
installed from the ubuntu packaging system.
Now that fixed the BEAUTIFY but the problem is no longer as severe as
before but I do see one process (the multi-threaded one) consume more
memory than everything else.
Which is the mod_wsgi daemon process which holds the web2py instance.
It will obviously be bigger, but if it keeps growing then you likely
have an issue with the application. There has never been any issue
with mod_wsgi which would see such memory growth.
If you were using mod_wsgi 2.X (preferably 2.5 or later), then those
options to WSGIDaemonProcess would at least allow it to recover itself
whil you sort out what the real problem is.

Look at process 6320. It is using way more memory than any other one.
Eventually it will fill the ram. Seems like a memory leak. Only one
process does it. I will it and another process takes his place.
What is going on?
I have never seen this problem before. Looks like a memory leak and
seems related to this:

Ubuntu still has a quite old mod_wsgi version in the main repository,
possibly even on mod_wsgi 1.X given you are using ancient ubuntu 8.04.
The latest mod_wsgi version is 3.1 and if can you should use that.
If you weren't using an ancient version of mod_wsgi I would have
suggested you change the configuration line:
WSGIDaemonProcess web2py user=www-data group=www-data
to:
WSGIDaemonProcess web2py user=www-data group=www-data display-name=%
{GROUP} maximum-requests=5000 inactivity-timeout=60
The 'display-name' option with that value will cause the process to be
listed in 'ps' output as '(wsgi:web2py)'. That way is easier to
identify separately from core Apache server processes. This option was
only added in mod_wsgi 2.0.
The 'maxiumum-requests' option would cause daemon process to be
shutdown and restarted after 5000 requests. That way if you do have a
problem with cache cleaning or Python object reference counting cycles
which cant be broken by the Python garbage collector, then you at
least throw everything away and start over again every so often.
The 'inactivity-timeout' option is another way of forcing a process
shutdown and restart to reclaim memory and start over. In this case if
no requests are received in 60 seconds since the last request and so
application is idle, it will shutdown and restart the process. This
option was only added in mod_wsgi 2.0.

[web2py] Problem with example in the book.
I have been working on section 3.6 of the book but cannot get past the
initial database sample. When I enter the following into db.py and
click on 'database administration' I get an error. The code entered
is:
*
db = DAL(sqlite://storage.db)
db.define.table('image',
Field('title'),
Field('file','upload'))
db.define.table('comment',
Field('image_id', db.image),

db.comment.email.requires = IS_EMAIL()
db.comment.body.requires = IS_NOT_EMPTY()
db.comment.image_id.writable = db.comment.image_id.readable = False
When clicking 'database administration' I get the following error:

Before I added the database code from section 3.6 I was able to access
the database administration for the initial tables.
Does anyone have suggestions on where I should be looking? I thought
I might be missing sqlite (haven't used Python on a while), but that
is built-in now.

A line with fcgihandler.py should appear once. If appears more than

Hi Raven
The name fcgihandler.py is just the name of a web2py start up file
passed to Python.
The name fcgihandler.py should not or need not appear anywhere in the
lightttpd.conf file, since there is no need to give lighttpd the
responsibility to start up web2py as an independent process.
What lighttpd needs to know is where the UNIX socket is that is
configured for use by web2py in fcgihandler.py. The name that
ligthttpd.conf uses to tell the rest of lighttpd.conf to use the UNIX
soscket is an arbitrary name. The suffix .fcgi does not need to appear
anywhere in lighttpd.conf, it is just a convention.
Maybe I should provide a link to a complete lighttpd.conf file
inhttp://www.web2pyslices.com/main/slices/take_slice/57
It might be difficult to escape from an attitude that web servers are
essentially used as dumb pipes by Python frameworks and as such need
to stay 'out of the way' with minimal involvement.

As a fail safe for a runaway process, you can set yet another option
to WSGIDaemonProcess to trigger a process shutdown and restart. This
option is:
cpu-time-limit=300
That is, once the process has consumed a total of 300 seconds of CPU
time it will automatically restart it. This option was added in
mod_wsgi 3.0.
Although it will curtail a blatant runaway process, normal processes
will obviously still eventually accumulate CPU time through normal
use, so it will also act as a periodic restart trigger for a process
even under normal operation. That is similar to how maximum-requests
option would also trigger a restart but based on number of requests.

problem with cache cleaning or Python object reference counting cycles
which cant be broken by the Python garbage collector, then you at
least throw everything away and start over again every so often.
The 'inactivity-timeout' option is another way of forcing a process
shutdown and restart to reclaim memory and start over. In this case if
no requests are received in 60 seconds since the last request and so
application is idle, it will shutdown and restart the process. This
option was only added in mod_wsgi 2.0.
To check which version of mod_wsgi is running you can look at the
startup messages for Apache, presuming ubuntu hasn't hacked the
startup message to disable display of Apache module information. The
message will be of the form:
Apache/2.2.2 (Unix) mod_wsgi/1.0 Python/2.3.5 configured
If you can't find that in main Apache error log from time when Apache
last restarted, then you will need to work out which version is
installed from the ubuntu packaging system.
Now that fixed the BEAUTIFY but the problem is no longer as severe as
before but I do see one process (the multi-threaded one) consume more
memory than everything else.
Which is the mod_wsgi daemon process which holds the web2py instance.
It will obviously be bigger, but if it keeps growing then you likely
Re: [web2py] Re: first gae app
I think this fixes it:
in a form this gets entered

a validation rule with this in it does the trick :)
a[3:-2].split(',u')

it now looks like

StringListProperty is a native gae type now supported by web2py:

http://groups.google.com/group/web2py/browse_thread/thread/7d284c9fa4...
To get around the like problem you can do something like this:
Model.all().filter('ngrams =', word).filter('ngrams ', word +

Check out Thadeus's code for a full example.
There's also info how to do this in the docs:

hi wes,
something like this could be really nice for browsing the function
docstrings. Do you intend to take it further?
If you use a StringListProperty to store all the ngrams (eg: web2py,
web2p, web2, web, we, w) then it could match partial words.

Hi Raven
The name fcgihandler.py is just the name of a web2py start up file
passed to Python.
The name fcgihandler.py should not or need not appear anywhere in the
lightttpd.conf file, since there is no need to give lighttpd the
responsibility to start up web2py as an independent process.
What lighttpd needs to know is where the UNIX socket is that is
configured for use by web2py in fcgihandler.py. The name that
ligthttpd.conf uses to tell the rest of lighttpd.conf to use the UNIX
soscket is an arbitrary name. The suffix .fcgi does not need to appear
anywhere in lighttpd.conf, it is just a convention.
Maybe I should provide a link to a complete lighttpd.conf file
inhttp://www.web2pyslices.com/main/slices/take_slice/57
It might be difficult to escape from an attitude that web servers are
essentially used as dumb pipes by Python frameworks and as such need
to stay 'out of the way' with minimal involvement.

I suspect my problem might be with this line
$HTTP[host] =~ (^|\.)example\.com$ {
Since I am running on a VPS I only have an IP address.
I tried
$HTTP[host] == 100.101.102.103 {

[web2py] batch upload of legacy files
Greetings, I am migrating a legacy application to web2py. Part of the legacy data is a large ( 50,000) collection of attachments - files of all different types, that were uploaded in various ways to the legacy application (typically as email attachments) and need to appear in the new web2py application. I can copy the physical files into the uploads directory of the web2py application, and I can insert appropriate rows into the attachment table in the database. Are there any special considerations that need to be addressed? The biggest question is: do the filenames *have* to comply with the filenames generated by web2py's upload functionality (table.field.uuid.b16encode.ext), or can I keep the existing filenames (e.g. image1.jpg, readme.txt, problem.bmp, sample.csv)? If I must conform to web2py's naming convention, what is the easiest way of constructing the uuid part of the filename (I have a separate data migration script written in Python that already migrates most of the other legacy data)?
