[web2py] Re: Err 24: too many files open

[dederocks]

Thank you Paolo for the benchmark!
In my case, I start at 107, and at the end of the process the count is at 
672!! nginx on the other hand is stable around 55.
And the culprit is (drums ...): redis! The large majority of the files 
opened are the redis port.
Extract from lsof:
uwsgi   2128 www-data  511u  IPv4  62305  0t0 TCP 
localhost:56632->localhost:6379 (ESTABLISHED)
uwsgi   2128 www-data  512u  IPv4  62536  0t0 TCP 
localhost:56661->localhost:6379 (ESTABLISHED)
uwsgi   2128 www-data  513u  IPv4  62361  0t0 TCP 
localhost:56639->localhost:6379 (ESTABLISHED)
uwsgi   2128 www-data  514u  IPv4  62377  0t0 TCP 
localhost:56641->localhost:6379 (ESTABLISHED)
uwsgi   2128 www-data  515u  IPv4  62392  0t0 TCP 
localhost:56643->localhost:6379 (ESTABLISHED)

Does someone know how to fix this?

But still looking for a simple way to avoid keeping the same values in

dederocks, I've just tried to run lsof -p  on a ubuntu server 
running web2py
In my case, it returns 138 opened files among libraries, sockets and so on; 
the most opened file is /dev/zero, opened 55 times.

just ensure that the user running apache has rw permissions on the web2py

@roberto: the uwsgi process is then indeed eating all the CPU - but I'm not 
sure it means uwsgi is the culprit, at least at this stage (could be the

Is there in linux a way to know who opened which file and when? lsof gives 
only the process, not the time.

Re: [web2py] www.web2py.com link does not resolve - is site down?

[Massimo Di Pierro]

Strange. They are the same app and same server, just different processes. 
They all seem to be up now.
One issue I have discovered is that pythonanywhere ignores regex in static 
files in config and therefore it lets web2py serve static files. Some 
static files are large and this cause processes to occasionally run out of 
memory and fail until re-started. I am working with PythonAnywhere to 
figure out how to properly deal with serving static files.

[web2py] Appending for validation using jQuery.

[Prasad Muley]

Hello All,
I am newbie web2py programmer. I tried to do custom validation 
 using jQuery but not gettng expected result. Code is as followed:

*Model-db.py*

db.define_table('taxpayer',
Field('name'),
Field('married','boolean'),
Field('spouse_name')
)
# I don't want use IS_NOT_EMPTY() in this table

*Controller-default.py*

def taxer():
grid=SQLFORM.grid(db.taxpayer,user_signature=False)
if request.args(0) in ['edit']:
form=grid.update_form
if form.process(hiderrors=False).accepted:
response.flash=form.vars
return dict(grid=grid)

*
*
*View- default/taxer.html*

{{extend 'layout.html'}}
{{=grid}}

jQuery(document).ready( function(){
var flag=0
jQuery('.web2py_form').submit(function(){
//Getting value from tracker status
var get_name=jQuery('#taxpayer_name').val()
if(get_name =="") {
if(flag==0) {
   //alert("Please Enter valid Name");  WORKING
   jQuery("
Please Enter 
Valid Name
").appendTo("#taxpayer_name__label")  // WORKING
   jQuery("
Please Enter 
Valid Name
").appendTo("#taxpayer_name") // NOT WORKING
  flag=1
}
return false
}
});  
});


Please help me for this.
I want to display error message for 'name' field as IS_NOT_EMPTY() does.
It successfully does for taxpayer_name__label even as well as 
taxpayer_name__row but isn't working for taxpayer_name id.

Re: [web2py] Re: [web2pyy] Mysql 2 Mongodb

[Alan Etkin]

Note: If you are restoring data with the DAL method import_from_csv_file 
(not the Table class method) using id_map={}, which is the method that 
should be used to keep references in sync, you should not have issues 
keeping reference values. I have tested it with a trivial db (a few records 
and a list:reference table field) and it worked. AFAIK, appadmin does not 
provide an interface to make dumps of or loading the entire database, but 
it is really simple to use them in a web2py shell.


BTW: I have noticed that there is a problem on database the dump method 
(DAL's export_to_csv_file) and filed this issue. 

http://code.google.com/p/web2py/issues/detail?id=1605

With that change, you should be able to move data across databases without 
problems (yet not preserving id values).

Neither you can (or should) with other adapters, for example, postgres. Here's 
section of the book about that issue:



"... In order to make a record uniquely identifiable across databases, they 
must:
 *  have a unique id (UUID),
 *  have an event_time (to figure out which one is more recent if multiple 
copies),
 *  reference the UUID instead of the id.
..."


Agreed, but because mongodb is a nosql you could push this away to the 
developer. (What I am not abviously)


> ... Because you have no relation between the records anymore.

There's a possible bug with the import feature or the mongodb adapter. Maybe 
you can file an issue in the project page adding as many info as possible to 
reproduce the problem. While changing the id numbers, the id references should 
be preserved between records.


I am going to see if I can create a testcase to reproduce the error, maybe its 
because of the order of the data in db.py


> 
#I am curious about the reason, would het not be smarter to just keep the 
original id's ? Afterall mongodb uses _id. So it does not bite. 


I did so forget about that :-) Thanks for reminding me. 


And thanks for taking the time to answer me. Its very much appreciated.

[web2py] Re: sqlform.factory multiple requires problem

If you use IS_IN_DB it will automatically check if is not empty.

The function IS_IN_DB, if used inside list brackets [IS_IN_DB(...,...)] 
will not show the dropdown. This is the correct behavior.

[web2py] Re: Need Apache help for "uploads" directory

[Joe Barnhart]

Well it's entirely possible I don't understand my problem.

Running on my macbook locally everything works like a charm.  On the "play" 
deployment server, which uses Apache, the script that deletes files after 
processing fails because it lacks "permission" (according to the web2py 
error log).  Also, when uploading the files Apache goes to 100% cpu and 
stays there, consuming RAM until I get tired of watching.  Admittedly, they 
are very large files (~200MB) but I don't see why Apache should consume >2G 
of RAM while spinning in some kind of loop.

Everything is set up as in the book and messages here -- I used Debian 
Linux for the play server and used www-data for the user and group, and put 
web2py under /home/www-user/.  The website works fine in all other ways, 
but just has issues uploading/downloading files from my web page file 
loader.

I must say this web deployment step is much harder than using web2py to 
create the site!

[web2py] Re: Multi column constraint

[villas]

Did you try the 'requires' separately,  eg

db.define_table('ts_mileage_rate',
Field('customer_id', 'reference ts_customer', 
required=True, notnull=True),
Field('mileage_rate_year', 'integer', required=True, 
notnull=True))

db.ts_mileage_rate.mileage_rate_year.requires=IS_NOT_IN_DB(db(db.ts_mileage_rate.customer_id
 
== request.vars.customer_id),
  'ts_mileage_rate.mileage_rate_year')

[web2py] Re: Need Apache help for "uploads" directory

[Niphlod]

there are no special permissions because apache can't serve the uploads 
directory by itself. Remember that "uploads" is not the same as "static". 
The uploads are interely managed by web2py.

it's a problem on the layers "at the base" of web2py, such as the os, nginx

Re: [web2py] Multi column constraint

[Richard Vézina]

Your code seem ok, maybe traceback could help... Or you can look at the
line poited by the traceback... Maybe you forgot "db." somewhere in front
of ts_mileage_rate

Can't say from you code, because it seems ok there. I thought it was caused
by the IS_NOT_IN_DB at first but I don't think so.

Good luck.

[web2py] Web2Py + TurnkeyLinux and Apache

[james c.]

I easily deployed my Web2Py app "with just a few clicks" through the 
TurnKeyLinux Hub onto Amazon EC2. The Web2Py Admin console shows that the 
app is running with Apache. However, it seems to still be running on Rocket 
from an error message related to SSL. Any SSL connection attempt is 
ignored. The Web2Py deployment recipes provide a length list of commands to 
deploy Apache, but I expect that the TKL Web2Py appliance has already taken 
care of that. Is there a web2py configuration parameter that "points" to 
Rocket Server or Apache?

thanks in advance for any advice, James

Re: [web2py] Behavior Driven Development in Web2Py

[Richard Vézina]

Hello Clarke,

There is lettuce :

http://net.tutsplus.com/tutorials/python-tutorials/behavior-driven-development-in-python/

Recently Vinicius make an aptempt to make it easier to Unit Test with
pytest and web2py :
https://groups.google.com/d/msg/web2py/CHfZTr5xHso/lZlGW5tPk6EJ

More of unittest, but I think that people here if they write test do
unittest, don't remember having read something about BDD on this list...

Cheer.

Re: [web2py] Re: [web2pyy] Mysql 2 Mongodb

Neither you can (or should) with other adapters, for example, postgres. 
Here's section of the book about that issue:

"... In order to make a record uniquely identifiable across databases, they 
must:

   - have a unique id (UUID),
   - have an event_time (to figure out which one is more recent if multiple 
   copies),
   - reference the UUID instead of the id.

..."
> ... Because you have no relation between the records anymore.

There's a possible bug with the import feature or the mongodb adapter. 
Maybe you can file an issue in the project page adding as many info as 
possible to reproduce the problem. While changing the id numbers, the id 
references should be preserved between records.

I am curious about the reason, would het not be smarter to just keep the

I don't think it is a good idea because that way, DAL would have to deal 
with two auto-generated record identifiers (adding redundant and confusing 
id fields) for any database operation.

[web2py] Behavior Driven Development in Web2Py

[Clarke Bishop]

I've been doing the online course, CS169x, from Coursera. The course uses 
Ruby/Rails, but I like Python better. They picked Rails because they said 
it was the best for programmer productivity. Maybe once you get way down 
the learning curve, they are right. However, I find all the Rails "magic" 
to be confusing and hard to debug.

So, I started looking for Rails for Python, and it seems Web2Py is the 
answer!

I do understand MVC, and have learned some Python, but I am still more of a 
newbie than not.

Here's my question. Are there behavior driven development tools for Web2Py? 
Like Cucumber for Rails. I had not known about this approach before, and 
learned a lot from the link below:
https://www.youtube.com/watch?v=bAu9j0nHOYw&feature=player_embedded

Actually, I think Cucumber could be used with Web2Py — I don't think it is 
Rails-specific. Still, I'm wondering if there is a more Web2Py-friendly 
tool.

Thanks for any ideas or pointers,

 Clarke

[web2py] Re: discovered something cool in web2py DAL

[Derek]

I believe that example of counting contains is in the book, so to anyone 
who didn't read the book this is new, however, the example was kind of 
confusing. I remember reading about it on the newsgroup that someone 
couldn't understand what was going on. You give a good example of how to 
rewrite that part of the book.

[web2py] discovered something cool in web2py DAL

[VP]

Maybe this was obvious, but I never thought I could do this kind of queries 
in DAL.  

Okay, let's say I have 2 tables:

Tags = db.define_table('tag', Field('name'))
Post = db.define_table('post', Field('title'), Field('tag', 'reference 
tag'))


Now, doing a join is easy using the query *(db.post.tag == db.tag.id)*

But if I have the following 2 tables, where a post might have many tags:

Tags = db.define_table('tag', Field('name'))
Post = db.define_table('post', Field('title'), Field('tag', 'list:reference 
tag'))

How do I select tags that occur in posts?  It turns out that this can be 
done very nice using the query:  *db.post.tag.contains( db.tag.id )*
*
*
I have used "contains", but I had thought that the argument for it must be 
a constant (e.g. a specific tag such as "news"), not something like 
db.tag.id.

Nice.

Counting tags occurrence (e.g. if you want to have a tag cloud) turns out 
to be quite simple:   *db( db.post.tag.contains(db.tag.id) 
).select(db.tag.ALL, db.tag.id.count(), groupby=db.tag.name)*

Nice!!

@auth.requires_login() has to be applied separately to each function you 
want to protect. David asked about protecting an entire controller. To 
avoid having to repeat the same decorator on every function in the 
controller (possibly forgetting when you add a new function), you can 
instead protect the entire controller with a single line at the top.

You can also do it in a model file to protect the entire application, but 
in that case you should add some logic to exclude /default/user from the 
check -- otherwise, users won't be able to get to the login page.

[web2py] Link to default value for db table field

[shapovalovdenis]

Hi!

Let's say I've following table defined:
db.define_table('page',
   Field('is_index', 'boolean'),
   Field('title', 'text', default=''),
   Field('block_content', 'text', default=''),
   Field('block_ad', 'text', default=''),
   Field('block_footer', 'text', default=''),
   format='%(title)s'
}

I've inserted several pages (rows) in it.

What would be the best way for block_footer to have the same value as in 
'index' rows, i.e. like the footer on many (if not all) pages of a web site 
stays the same.

Basically I'm looking for a way to reference index row's footer value in 
other page's block_footer filed leaving a possibility for customization in 
case some page would require a different footer.

Or if you want to get the automatic redirect and messaging behavior of the 
@auth.requires_login() decorator, you can use this trick:

# At the top of the controller
auth.requires_login()(lambda: None)()

auth.requires_login() returns a decorator that takes a function and returns 
another function -- above just passes a dummy lambda function to the 
decorator and then calls the resulting function to run the requires_login 
code. Works with the other Auth decorators as well (all of which ultimately 
call auth.requires(), which is the method that produces the decorator).

[web2py] Need Apache help for "uploads" directory

[Joe Barnhart]

So a central part of my website is a repository of files/objects that are 
added and removed.  I've chosen to use the "uploads" folder in my 
application directory, with additional feature of scattering the files into 
subdirectories (because I expect a LOT of them).

I'm trying the stock apache2 setup from the book but I find it has no 
provision for permissions on the uipload directory.  I copied the setup for 
the "static" directory and was able to put files in the directory, but I 
can't delete files from the directory within my site.

Has anyone worked out the changes needed to the stock Apache2 setup that 
accommodates the upload directory?  Seems like it would be a nice 
addition/update to the book setup.

[web2py] strange decimal form field comparison result

[黄祥]

hi folks,

i have a decimal form field that validate during submit (running on web2py 
2.5.1):

e.g. on controller
def product():
grid=SQLFORM.grid(db.product, onvalidation=__onvalidation_product)
return locals()

def __onvalidation_product(form):
*if form.vars.price_list >= form.vars.selling_price:*
form.errors.selling_price = 'Selling Price must Greater than Price 
List'

when i insert price_list = 3 and selling_price = 3 the notification appears 
in the form field  prevent the data to be inserted. i think, it should be : 
when i insert price_list = 3 and selling_price = 3 the notification not 
appears and the data can be inserted

but
def __onvalidation_product(form):
*if form.vars.price_list > form.vars.selling_price:*
form.errors.selling_price = 'Selling Price must Greater than Price 
List'

when i insert price_list = 3 and selling_price = 3 the notification not 
appears and the data can be insert. i think, it should be : when i insert 
price_list = 3 and selling_price = 3 the notification appears to prevent 
the data to be inserted

is there any mistake in my logic or code above?

thanks and best regards

It seems that static/js/jquery.js is the problem.  Replacing the file in 
the working app with the one from the Welcome app, breaks things.

[web2py] Re: Failing to execute python script from the Windows CMD

[Massimo Di Pierro]

If you use the binary distribution you do not need "python" and you should 
call web2py with:

> web2py.exe -S myApp - M -R applications/myApp/scripts/myAppScript.py

but since you have python installed, you should follow Anthony's advice and 
run web2py form source.

 If your browser is set to English it is in Eglish 
 If your browser is set to Italian it is in Italian (traduzione di 
 Giovanni Cannata) 

 I do not have other translations but I can enable them if you have 
 them. Let me know.

[web2py] Re: [web2pyy] Mysql 2 Mongodb

[Mike Veltman]

I am just playing around with mongodb and web2py 

I noticed that when I just make a web2py dump of my mysql db and then upload it 
to mongodb some of the "joins" now just rec id's are right and some are newly 
generated. 

Also would it be possible to keep id to be web2py specific and to use _id for 
mongodb ? 




 
I was wondering if it was a bug. In this case in the setup table the pointers 
to the frame work fine, but the pointers in the setupprofile named lparprofile 
do not exist anymore in the lparprofile table.

Sorry I am a bit slow, being busy.

But I did upload it from csv file. So  it should keep the reverences. But it 
did not do so for all tables.

Also I concluded that because all the references are replaced by mongodb id's 
it is not possible to say dump a table  with references in one database and 
then restore it on mongodb. Because you have no relation between the records 
anymore. You replaced the web2py id's in mongodb with mongodb id's.

I am curious about the reason, would het not be smarter to just keep the 
original id's ? Afterall mongodb uses _id. So it does not bite.
