[web2py] Re: PostgreSQL migrate / fake_migrate_all failure with relation does not exists
Hi Tom,
wiki's tables are not present.
You have to include them during the migration, probably you have defined
the wiki object in a controller?

This will happen for any relation trying to commenting them out etc.
Running a fake_migrate_all and the problem still persists, so I can not
find a way around manually modify my PostgreSQL schema at the moment.
Any suggestions?

Assuming the first line is in a call to the URL() function and the view in

response.get_vars.

[web2py] Custom validator - pass record id to validator for update operations
Hello all, I am developing a web2py application and I am writing the logic to control stock of certain items. To that end, I wrote a custom validator which is working fine when creating new sale items. Now the problem arises when updating these sale items, because I would need to know the actual record being updated to adjust the logic in this cases. I could get this information through ._before_update method, but how would I pass it to the validator ? I am not sure if this is the best way to do it. I will appreciate any help on this matter!

[web2py] Subclassing IS_IN_SET - one piece missing.
Hi,
I wanted to create a validator which creates a dropdown of users in a
certain auth group.
I figured I could shortcut this by inheriting from IS_IN_SET, see class
below.
This works fine for SQLFORMS in create mode (drop dow with just what I want
to see) and for read-only mode (I see the user name, not the id) , but for
a SQLFORM in edit mode which is pointing at an existing record, it doesn't
pre-select the entry in the options drop-down.
Any ideas on how I go about getting this to work, or is there a simpler
solution?
If you use this validator in the DAL, you can see the result the admin
pages, so you have an easy way to test if you want to play around with it.
Thanks,
class IS_USER_IN_GROUP(IS_IN_SET):
A validator that can be used like requires = IS_USER_IN_GROUP()
Provides a drop down of users in that group.

labels = []
staff_groups = db((db.auth_user.id==db.auth_membership.user_id)
(db.auth_group.id==db.auth_membership.group_id))
rows = staff_groups(db.auth_group.role ==
group_name).select(db.auth_user.ALL,
orderby=db.auth_user.first_name|db.auth_user.last_name)
for user in rows:
keys.append(user.id)
labels.append('%s %s' % (user.first_name, user.last_name))
IS_IN_SET.__init__(self, keys, labels)
def formatter(self, user_id):
hits = db(db.auth_user.id == user_id).select()
if len(hits) == 1:
user = hits.first()
return '%s %s' % (user.first_name, user.last_name)

[web2py] Re: Custom validator - pass record id to validator for update operations
Hi Clara, I think (someone please correct me if I'm wrong -- and have a look at my other question posted just after this :D) that the validator has no access to the record. But because you can set the validator on a field at any time, one solution is to chang your validator class so it knows about the record id, and only assign the validator to the table's field just before you need to use it in a form, but after you have obtained the record id. class MY_VALIDATOR(IS_IN_SET): def __init__(self, record_id=None): self.record_id = record_id #whatever your validator does def __call__(self, value): if value == self.self.record_id: #whatever def some_controller_url(): record_id = request.vars.record_id #Override the validator set in models (if any) with this validator which does have knowledge of the record db.my_table._my_field.requires = MY_VALIDATOR(record=record_id) form = SQLFORM( db.my_table, record=record_id) ...#Table will be built with a validator which knows about your record :) Does this make sense?

Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
Sorry about the delay. I recently installed pgbouncer. I let postgresql
max_connection set to 80, and configure pgbouncer with a max_client_conn of
1000 and a default_pool_size of 20.
Now when I check pg_stat_activity I can see different amounts of idle
connections per app, more accordingly with that app's traffic. What I mean
is that I can see more connections for the apps with higher volumes of
traffic and less connections for the apps with lower volumes of traffic.
What I still don't understand is the max_connections setting of
postgresql vs the max_client_conn of pgbouncer. For what I've read in
[1] and [2] it's ok to set those variables for example in the way I did,
leting postgresql max_connections in an appropiated value (in my case,
using pgtune, 80 max_connections) and using a high value for
max_client_conn on pgbouncer configuration.
What isnt' clear to me is: what will happen when one of the apps has more
than 20 active connections to pgbouncer and requests keep coming in? The
ideal (for me, in this case) would be that next requests just stay waiting
(browser saying waiting for domain.com).
In the other hand, related to Michele comment, right now I have every flup
server running with max-procs set to 1, this is how my lighttpd virtual
hosts look like:
$HTTP[host] == diarioprimicia.com.ar {
server.document-root = /var/www/diarioprimicia
server.dir-listing = disable
server.error-handler-404 = /diarioprimicia.fcgi
server.kbytes-per-second = 256
connection.kbytes-per-second = 128
accesslog.filename = /var/log/lighttpd/diarioprimicia_access.log
fastcgi.server = (
.fcgi = (localhost = (
check-local = disable,
max-procs = 1,
socket = /var/tmp/lighttpd/diarioprimicia.sock,
bin-path = /var/www/diarioprimicia/diarioprimicia.fcgi)
)
)
}
Then the file indicated by bin-path contains the following:
#!/usr/bin/python
import sys
import gluon.main
from flup.server.fcgi_fork import WSGIServer
application=gluon.main.wsgibase
WSGIServer(application).run()
Another strange thing I see (strange for me, because I don't fully
understand in) is that, regardless of setting max-procs to 1, when I use
pgrep to check for fastcgi processes I can see exactly 5 processes for
every app.
I'm sorry to mix all this stuff in this post, if you think that I should
move it to other forums, let me know.
Thank you very much!

Yes in deed. I've restarted the webserver and the database server.
Recently I've tried setting pool_size to 1 for every app, that is, for
every website. Restarted postgresql and webserver (lighttpd). And then I
used this SQL statement to check the total count of connections for every
database (or what it is the same, for every app, because every app has its
own database):
select datname, count(*) from pg_stat_activity group by datname order by
datname;
Just to remind, I have around 13 apps running, that is, 13 websites, 13
databases.
With this new configuration of every app using a pool size of 1, I
restarted the database server and the webserver, and then I ran the
previous SQL statement to see the total connections for every app, and I
see 5 idle connections for every app, that is, for every website that has
some visitors browsing the site.
A couple of the websites almost never have visitors, so, for those
websites, there were no idle connections. Then I go to the homepage of
those websites, rechecked connections, and there I see 5 idle connections
for those websites.
I already checked and re-checked the code of my app to be shure that I'm
setting pool_size parameter correctly.
In the other hand, I've been testing pgbouncer on localhost, reading
about it, and I'll be setting it for production. For what I've read,
independently of the postgresql max connections, I can set pgbouncer to a
max_client_conn of 2000 (for example) with a default_pool_size of 20. Then
all the apps connect to pgbouncer, and pgbouncer will multiplex connections
to postgres. However I don't want to mix things in this post, regardless of
pgbouncer, I would like to understand why I can't get to work web2py's
pooling mechanism.
I'm really grateful for your help! I'll continue trying to figure it
out. Any comment or suggestion will

Hi,
I have a weird bug that seems to be triggered when using the multiprocessing
module, if web2py is launched from another directory.
I've tried to isolate the issue. To reproduce the issue, take a clean
web2py source tarball, and make the following changes:
1. to the end of *applications/welcome/controllers/default.py* add the
lines:
import alpha
def bravo():
return alpha.charlie()
2. create a new file *applications\welcome\modules\alpha.py* with the
following content
from multiprocessing import Process, Manager
def delta(output):
output.append('Hello, world!')
def charlie():
output = Manager().list()
p = Process(target=delta, args=(output,))
p.start()
p.join()
return output[0]
3. run it normally,
d:\code\temp\web2pypython web2py.py
... hit *http://127.0.0.1:8000/welcome/default/bravo
http://127.0.0.1:8000/welcome/default/bravo* ... everything works
4. change the current working directory, and relaunch
d:\code\temp\web2pycd ..
d:\code\temppython web2py\web2py.py
and you get an error. An unhelpful ticket, but the console has the
following traceback:
Traceback (most recent call last):
File string, line 1, in module
File D:\Python27\lib\multiprocessing\forking.py, line 380, in main

ImportError: No module named web2py
If it helps, I put a print statement before File
*D:\Python27\lib\multiprocessing\forking.py*, line 489, and it printed
out:
['d:\\code\\temp\\web2py\\web2py']
Something is causing the path to add the directory web2py twice!
If I run the code from one directory above that:
d:\code\tempcd ..
d:\codepython temp\web2py\web2py.py
then the following is printed:
['d:\\code\\temp\\web2py\\temp\\web2py']
Again the path is repeated twice.
Can anyone help me understand what is causing this issue? What is a
potential fix?
If it helps, the real bug got triggered when running web2py behind Apache
on Windows (modwsgi), since the wsgi script was launched from some random
Apache directory.

Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
@lisandro: michele is right.. the pool_size parameter calculation are accurate only if there's one process per app. web2py can't coordinate pools among different processes... also, max_client_conn is exactly the maximum number of connection the pgbouncer process will allow coming in. Once over the max, others will be queued. What pgbouncer does is exactly what web2py does if it runs in a single process and with a single DAL connection: it keeps n connections open to the backend and recycles connections coming in. Once full, the latest coming in needs to wait for a connection to be freed. -- 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.

Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
What you have here is lighttpd starting 1 forking flup server. The
important part is this:
from flup.server.fcgi_fork import WSGIServer
With that you have a python interpreter for each request, up to a maximum.
The default is 5 spare children, the default maximum is 50.
Under lighttpd is also possible to use fcgi_single and max_procs = 5 with
similar results [I'd expect a slightly bigger memory footprint].
Since you have a forking/multiprocess configuration, you need to have a
single connection in the web2py connection pool so pool_size=1 is what you
need, anything more is just a waste of resources and postgres connections.
The max number of open connections should be (max_num_wsgi_proc[flup] *
pool_size[web2py DAL]) * (max_procs[lighttpd] * num_applications[lighttpd]).
About pgbouncer, IMHO you should use it only if you have n client and m max
postgresql connections, and you have n m. To speedup things you can use
memcache/redis and/or a more complex setup with pgpoolII and multiple
postgres backends.

Sorry about the delay. I recently installed pgbouncer. I let postgresql
max_connection set to 80, and configure pgbouncer with a max_client_conn of
1000 and a default_pool_size of 20.
Now when I check pg_stat_activity I can see different amounts of idle
connections per app, more accordingly with that app's traffic. What I mean
is that I can see more connections for the apps with higher volumes of
traffic and less connections for the apps with lower volumes of traffic.
What I still don't understand is the max_connections setting of
postgresql vs the max_client_conn of pgbouncer. For what I've read in
[1] and [2] it's ok to set those variables for example in the way I did,
leting postgresql max_connections in an appropiated value (in my case,
using pgtune, 80 max_connections) and using a high value for
max_client_conn on pgbouncer configuration.
What isnt' clear to me is: what will happen when one of the apps has more
than 20 active connections to pgbouncer and requests keep coming in? The
ideal (for me, in this case) would be that next requests just stay waiting
(browser saying waiting for domain.com).
In the other hand, related to Michele comment, right now I have every flup
server running with max-procs set to 1, this is how my lighttpd virtual
hosts look like:
$HTTP[host] == diarioprimicia.com.ar {
server.document-root = /var/www/diarioprimicia
server.dir-listing = disable
server.error-handler-404 = /diarioprimicia.fcgi
server.kbytes-per-second = 256
connection.kbytes-per-second = 128
accesslog.filename = /var/log/lighttpd/diarioprimicia_access.log
fastcgi.server = (
.fcgi = (localhost = (
check-local = disable,
max-procs = 1,
socket = /var/tmp/lighttpd/diarioprimicia.sock,
bin-path = /var/www/diarioprimicia/diarioprimicia.fcgi)
)
)
}
Then the file indicated by bin-path contains the following:
#!/usr/bin/python
import sys
import gluon.main
from flup.server.fcgi_fork import WSGIServer
application=gluon.main.wsgibase
WSGIServer(application).run()
Another strange thing I see (strange for me, because I don't fully
understand in) is that, regardless of setting max-procs to 1, when I use
pgrep to check for fastcgi processes I can see exactly 5 processes for
every app.
I'm sorry to mix all this stuff in this post, if you think that I should
move it to other forums, let me know.
Thank you very much!

I suggest to work around the problem by setting the number of threads

Yes in deed. I've restarted the webserver and the database server.
Recently I've tried setting pool_size to 1 for every app, that is, for
every website. Restarted postgresql and webserver (lighttpd). And then I
used this SQL statement to check the total count of connections for every
database (or what it is the same, for every app, because every app has its
own database):
select datname, count(*) from pg_stat_activity group by datname order
by datname;
Just to remind, I have around 13 apps running, that is, 13 websites, 13
databases.
With this new configuration of every app using a pool size of 1, I
restarted the database server and the webserver, and then I ran the
previous SQL statement to see

If by two web2py apps you mean two different web2py installations (with the web2py code duplicated, so that they can run different versions of web2py, for example), then I can say: we recently followed this tutorial: http://www.techshinobi.com/index.php/multiple-web2py-instances-with-uwsgi-emperor-and-nginx/ and it worked for us. If your two web2py apps can share the web2py code, and you can arrange the routing staff to your satisfaction, you don't even need that. Have you tried to just define several sites in /etc/nginx/sites-available, one of them as in the web2py book, two of them like in the default nginx site?

Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
Thank you very much Niphlod and Michele for your help! Now I have a more
clear understanding of all this. I understand now why I was seeing 5
fastcgi processes regardless of the max-procs configuration (that was
because I was using fcgi_fork, and I was actually seeing one process and
its 5 children).
Michele, abount using pgbouncer when having more clients connections than
max postgresql connections, I think that's my case (correct me if I'm
wronk). All the sites I'm hosting are news sites, and ocassionally some of
them have sudden spikes in traffic. The last time one of the sites
presented a high peak on traffic, connections reached the postgresql
max_connections limit and, therefor, **all** the applications started
throwing intermitent HTTP 500 errors.
So I started my research to see what could I do to **avoid compromising
some apps when one of them is getting high traffic**. Above all, I want to
be able to **control the limits for every app**. I started setting
server.kbytes-per-second and connection.kbytes-per-second for every app.
However that didn't resolve the problem of high database connection
requests.
With the last info you gave me, I think now I can achieve my goal playing
around a little with this settings (please correct me if I'm worng):
- max-procs for the fastcgi of every app: I could set it to 1 for apps
with lower traffic, and set it to a higher value for apps with higher
traffic (of course, always checking stats to see what happens).
- pool_size pgbouncer parameter: I mean modifying this value for every
database, using a larger pool for apps with higher traffic, and viceversa.
The cool stuff here is that with pgbouncer I can check stats of clients,
pools, etc. My goal here is to set a limit for an app, and if a new
connection is requested but the pool is full, the client keeps waiting
until a connection is freed (no http 500 error).
I'll be trying these changes and I'll be posting here the results.
As always, any comment is really appreciated. Thank you again for the help!

Re: [web2py] Re: Displaying blob image on login page
I've tried both solutions and it's not working here
1) decode is giving me following error.

class 'binascii.Error' Incorrect padding
2) Second option is not working.
I've printed image path but it didn't display on login page.

[web2py] dummy database to hold legacy db
Hi, I manage data from different people and display selected data on page. Therefore I work with a lot of legacy databases. I can automatic extract tables from these external dbs, then put them into a list of DAL objects. How can I unify the tables into one single db? Then the controller will see one dummy_db. when a request is made to dummy_db.table_one , the request will be wired to the real DAL object. I am not sure how I should proceed, any idea to share?

[web2py] web2py doesn't retrieve the latest user-memberships from ldap.
Hi Guys, I've a small question regarding the auth-module when using ldap. I know that when a user doesn't exist in the web2py tables, web2py will retrieve the user along it's membership into the db upon his first login. However i've noticed that web2py doesn't uypdate this info when the user is already known, but the memberships in ldap has been changed. Is this normal behaviour? And are there any known work-around for this? With kind regards.

[web2py] Re: PostgreSQL migrate / fake_migrate_all failure with relation does not exists
Using the wiki as an example was a bit stupid.
This happens to all my tables with a foreign key.
The tables exist, but it happens when i add a field.
As I understand fake_migrate it regenerates the meta data in databases.
So if I first fake_migrate on the database that is exactly the same as my
models.
I expect turning on migrate to true to do nothing after the fake migrate.
But it throws the error for every single table that have a foreign key.
I have tried to empty the databases directory before the fake_migrate, but
I'm still stuck.
It still works on my production server. Copying to local with nothing
changed throws the error as soon as I turn on migrate. (Also after fake
migrate)
I also downloaded and renamed the databases files from the server, to see
if that would work.
Thinking about it now, I have not fully deleted and recreate the entire
local/develop pg_database / before import. Will try that next.

Hi Tom,
wiki's tables are not present.
You have to include them during the migration, probably you have defined
the wiki object in a controller?

Running a fake_migrate_all and the problem still persists, so I can not

Any suggestions?

[web2py] Re: form warning
Thank you Massimo,
here is my situation:
I would like to check if LastName and FirstName already exist in database
and warn user but allow him to proceed (there are people with sam name and
lastname).
The idea is to issue a warning when user have just these two fields filled
so that he do not fill whole form and finally find out that a person is
already in database.
Is javascript on client side with ajax call my best bet?
Any sugestions?

It depends on where you want to do. Personally I would not do this inside

[web2py] long running rpc call
Hi, We're making a number of rpc calls to other services using jsonrpc, and a few of them are particularly long running. I'd rather not use the scheduler, but instead was wondering if I could associate a jsonrpc httpclient in python to the current context so that longer tasks wouldn't block other incoming requests. I tried initially to just do a setattr on current (it's thread local storage as far as I understand), but that doesn't seem to work. Anyone have better ideas? Or am I just doing this completely wrong.
