Re: [web2py] Re: Chrome:LOAD and ajax problem

[tomasz bandura]

Hello,

After investigation, i added error handler to web2py_ajax_page and the
error's result was:


function AjaxFailed(result) {
  alert("FAILED : " + result.status + ' ' + result.statusText);
}

and the result:

result.status:0
result.statusText): 'error'

It looks rather as a jquery issue...

Regards,
Tomasz

In django, the derivaties are called Open Source Django Projects and 
described as stand-alone applications written using Django. They also have 
classifications into categories based on functionalities in the list. Is 
this something that can be useful to web2py?

That's roughly what http://www.web2py.com/appliances is supposed to be,

[web2py] Re: Can't run web2py because of socket.gethostbyname problem

[Mobility]

I am not getting host name. I can run web2py on local host. When I go to my 
test deployment machine with ML Server I first get an error saying that 
wsgihandler.py file does not have exec permission. After I give permission 
on the file, chmod a+x, it says gives me an error saying premature end of

That's good. I've been trying to reproduce it in a test case, and failing. I 
thought maybe that Storage needed to implement __contains__, but I couldn't

The same issue but with an installation script on CentOS. The web2py daemon 
does not seem to create the .w2p file, so the NEWINSTALL file remains 
whenever web2py is started and creating new apps from the admin fails. 

I'd like to start and stop the rocket server within the installation .sh 
script as a workaround, but there is no web2py.py option to start and stop 
the builtin server.

Perhaps I can download a stable welcome.w2p package during installation 
from somewhere and remove the NEWINSTALL. Would be that possible?

I didn't check the shell syntax, but you get the idea.

if [ -f NEWINSTALL -a -d applications/welcome ]; then
python -c "from gluon.fileutils import w2p_pack; 
w2p_pack('welcome.w2p','applications/welcome')"
rm NEWINSTALL

[web2py] Webservice for web widgets: security

[Tito Garrido]

Hi Folks,

I have created a jsonp function that will be used on a script so some other
people could use widgets with just 2 lines like:

http://example.com/widget/script.js";
type="text/javascript">

This script will call the jsonp function using:

$.getJSON(widget_url, function(data) {
  $('#example-widget-container').html(data.html);
});


How could I prevent people from execute my webservice funtion from another
"js" file or a modified version?

I have checked request.env variable but I didn't find anything that I could
say:

*This call is from a javascript located in example.com, otherwise ignore.*

Thanks in advance!

Ok, I'm starting to understand.  So looking at the manual

form2 = FORM(INPUT(_name='name', requires=IS_NOT_EMPTY()),

return dict(form1=form1, form2=form2)

I would have to assume that the hiddens are only generated
because of the call to FORM.accepted().  Should I assume then
that the 'formname' keyword is only necessary when there is
more than one form in the page?

Looks ok, I found this alternative (which is almost identical, but imports 
widget.py):

sudo -u uwsgi python$PREFIX -c "from gluon.main import save_password;from 
gluon import widget;save_password('$PW',443);widget.console()"


Borrowed from the ubuntu deployment script to create the admin password, 
adding the console() call from the web2py start
At least It works if tested separately

Thanks

[Anthony]

Correct. FORM.process() ultimately calls FORM.accepts(), which adds a 
"formname" attribute. When the form is serialized in the view, the 
FORM.xml() method calls FORM.hidden_fields(), which creates a _formname 
hidden field and, optionally, a _formkey hidden field (the latter is 
created when session is passed to .accepts() and is used to protect against 
CSRF and double submission). For a FORM object, _formname defaults to 
"default", and for a SQLFORM, it defaults to "[table_name]/create" or 
"[table_name]/[record_id]".

Yes, though as noted above, when the formname argument isn't specified, 
there will still be a default _formname.

[web2py] run code only if you are a worker

[Vincenzo Ampolo]

Hi,

I've an import that takes too much time and resources. Basically it sets
up a NLTK tagger.

I need this feature imported only if I'm runing as a worker. If I'm
running the webserver or the shell I don't need that import at all.

Is there a way to detect if I'm a worker when the models/modules are
imported?

Thank you.

[web2py] Apache vhost configuration for web2py with mod_wsgi and SSL

[Daniel Gonzalez]

Hi,

I am trying to setup an apache vhost with SSL to serve web2py. I have 
succeeded in setting up mod_wsgi, with the following vhost configuration 
file:


  ServerName www.example.com


  WSGIDaemonProcess web2py user=www-data group=www-data \
   display-name=%{GROUP}
  WSGIProcessGroup web2py
  WSGIScriptAlias / /var/www/web2py/wsgihandler.py


  
AllowOverride None
Order Allow,Deny
Deny from all

  Allow from all

  


  AliasMatch ^/([^/]+)/static/(.*) \
   /var/www/web2py/applications/$1/static/$2
  
Order Allow,Deny
Allow from all
  


  
Deny from all
  


  
Deny from all
  





Now I need to setup the SSL part. I am trying with this:

NameVirtualHost *:443

ServerName portal.wavilon.com


WSGIDaemonProcess web2py user=www-data group=www-data display-name=%{
GROUP}
WSGIScriptAlias   / /var/www/web2py/wsgihandler.py


 # static files do not need WSGI
 
 Order Allow,Deny
 Allow from all
 


# everything else goes to web2py via wsgi
 
 Order deny,allow
 Allow from all
 WSGIProcessGroup web2py
 


AliasMatch ^/([^/]+)/static/(.*) 
/var/www/web2py/applications/$1/static/$2



Order Allow,Deny
Allow from all




Deny from all




Deny from all



SSLEngine On
SSLCertificateKeyFile /etc/ssl/private/server.insecure.key
SSLCertificateFile/etc/ssl/certs/server.selfsigned.crt


# SSL workaround for MS Internet Explorer
BrowserMatch "MSIE [2-6]"  nokeepalive ssl-unclean-shutdown 
downgrade-1.0 force-response-1.0
BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown


But this is not yet working. Can somebody comment, or better yet, can 
somebody provide an example of a vhost configuration for mod_wsgi + ssl + 
web2py?

Thanks,

Re: [web2py] Webservice for web widgets: security

[Bruno Rocha]

I think you can generate a KEY in script.js (you need to generate this file
dynamically)

So you will have a key to check back when the widget gets rendered.

You might consider using CORS: http://www.html5rocks.com/en/tutorials/cors/

[web2py] Re: run code only if you are a worker

[Niphlod]

never had this kind of requirement, so at the moment there's no such 
possibility.
Just my 2 cents (and if this results unfeasible I'll think about more, 
please bear with me for a moment)

For my current understanding, if you put that "megacall" into modules, when 
the webserver is started (i.e. you are not a worker) the module is imported 
only at the first access.
Assuming that in fact this is what happens, this "workaround" is not 
feasible ?

Also, if you need "totally-separated" environments (i.e. you use some kind 
of functions and/or modules ONLY in workers and NEVER in the web 
application) why don't you use the "external" mode of the scheduler ?

i.e.

outside web2py folder , create tasks.py

import mysuperdupermodule
def mysuperfunction(args):
  mysupderdupermodule.dothatwork(args)

tasks = dict(mytask=mysuperfunction)


and then start the scheduler NOT in embedded mode: cd to the web2py.py 
folder and
python gluon/scheduler.py -u dburi -f applications/myapp/databases/ -t /path
/to/tasks.py

PS: in order to access the scheduler tables on the webapplication (i.e. you 
queue there your tasks) you still need to have a models/scheduler.py with 
from gluon.scheduler import Scheduler; mysched = Scheduler(db, migrate=False
)

That would remain a "dumb" call just to have the table definitions in place 
and to be able to access them.

[web2py] IS_DATETIME_IN_RANGE validation error datetime format

[Shane Tzen]

There seems to be a unexpected behavior regarding the form validation
error datetime format.

In languages/en-us.py, I redefined '%Y-%m-%d %H:%M:%S' to '%m-%d-%Y
%I:%M %p'.  views/web2py_ajax.html says var w2p_ajax_datetime_format =
"{{=T('%Y-%m-%d %H:%M:%S')}}";.

Even though the calendar widget generates the expected datetime
format, upon validation, if there is an validation error, the datetime
format doesn't seem to be translated (i.e. it's still %Y-%m-%d
%H:%M:%S).

I've also to set db.table.field.requires to
IS_DATETIME_IN_RANGE(format=T('%Y-%m-%d
%H:%M:%S'),minimum=datetime.datetime.now()) with no effect.  However,
if instead I set requires to IS_DATETIME(format=T('%Y-%m-%d
%H:%M:%S')), then the validation error message displays the proper
time format.

Please let me know if I'm doing something wrong.

Thanks.

[web2py] Re: run code only if you are a worker

[Anthony]

I think when you run web2py with the -K option, 
request.global_settings.scheduler exists and is set to the name/names of 
the apps passed after the -K option (otherwise, it should be None).

[web2py] Web2py service won't start on Windows

[joe]

Hello

I am running apache on a dedicated windows server (2008).  As of this 
morning, it was running successfully as a process.  But it needs to be a 
service, and that is causing me a 404 error.  Basically, apache runs just 
fine as a service, but when I install and start web2py as a service, it 
starts, and then immediately stops, no matter what I do.  Here is my 
options.py:

import socket, os
ip = socket.gethostname()
port = 443
password = ''
pid_filename = 'httpserver.pid'
log_filename = 'httpserver.log'
ssl_certificate = "
ssl_private_key = "
numthreads = 10
server_name = socket.gethostname()
request_queue_size = 5
timeout = 10
shutdown_timeout = 5
folder = os.getcwd()

[web2py] Re: Web2py service won't start on Windows

[LightDot]

My guess is that you have Apache and Rocket (web2py's internal web server) 
both claiming port 443 at the same time. Do you want to use Apache to run 
web2py or..?

Ales

[web2py] strange response.flash

[Martin Weissenboeck]

I have tried:* response.flash="Auswählen"* (German for "select") and I got *
"Ausw%C3%A4hlen"*. Looks like urllib.quote, but why?
And in some other contexts  I got "*Auswählen*" as expected. I could not
find any rule.

I am using the trunk from yesterday.

Then I wrote some test functions. I have written the results after each
block:

def flash1():
redirect (URL('flash1a', args=['hello there']))

def flash1a():
response.flash=request.args[0]
return dict(text='done')

Result:  *hello_there*  (with an underscore in place of the space)
--

def flash2():
redirect (URL('flash2a', args=['hello there äöü']))

def flash2a():
response.flash=request.args[0]
return dict(text='done')

Result: *Invalid request*. I thought "args" uses urllib.quote?
--

def flash3():
redirect (URL('flash3a', vars=dict(t='hello there äöü')))

def flash3a():
response.flash=request.vars['t']
return dict(text='done')

Result: *hello there äöü*  ok!
--

import urllib

def flash4():
response.flash='hello there äöü'
return dict(text='done')

Result:  *hello there äöü*  ok
--

def flash4a():
response.flash=urllib.quote('hello there äöü')
return dict(text='done')

Result: *hello%20there%20%C3%A4%C3%B6%C3%BC*  ok
--

def flash5():
redirect (URL('flash5a', args=[urllib.quote('hello there äöü')]))

def flash5a():
response.flash=urllib.unquote(request.args[0])
return dict(text='done')

Result*: invalid request*
--

def flash6():
return dict(load=LOAD('default', 'flash6a.load'))

def flash6a():
response.flash='hello there äöü'
return dict()

Result: nothing!!
--

def flash7():
return dict(load=LOAD('default', 'flash7a.load', vars=dict(t='hello
there äöü')))

def flash7a():
response.flash=request.vars['t']
return dict()

Result: nothing!

Some strange results, isn't it?

All functions again if someone wants to try it himself:

def flash1():
redirect (URL('flash1a', args=['hello there']))

def flash1a():
response.flash=request.args[0]
return dict(text='done')

def flash2():
redirect (URL('flash2a', args=['hello there äöü']))

def flash2a():
response.flash=request.args[0]
return dict(text='done')

def flash3():
redirect (URL('flash3a', vars=dict(t='hello there äöü')))

def flash3a():
response.flash=request.vars['t']
return dict(text='done')

def flash4():
response.flash='hello there äöü'
return dict(text='done')

import urllib

def flash4a():
response.flash=urllib.quote('hello there äöü')
return dict(text='done')

def flash5():
redirect (URL('flash5a', args=[urllib.quote('hello there äöü')]))

def flash5a():
response.flash=urllib.unquote(request.args[0])
return dict(text='done')

def flash6():
return dict(load=LOAD('default', 'flash6a.load'))

def flash6a():
response.flash='hello there äöü'
return dict()

def flash7():
return dict(load=LOAD('default', 'flash7a.load', vars=dict(flash='hello
there äöü')))

def flash7a():
response.flash=request.vars.flash
return dict()

Any answers welcome!
Regards, Martin

[web2py] Re: strange response.flash

[Anthony]

This issue is not with response.flash but with request.args. The characters 
allowed in args are fairly restrictive -- here are the regexes used: 
http://code.google.com/p/web2py/source/browse/gluon/rewrite.py#51, 
http://code.google.com/p/web2py/source/browse/gluon/rewrite.py#575.

In the LOAD() examples, try setting ajax=True and the flash should work.

[web2py] Re: Centos 5 script for Nginx with Uwsgi and Web2py

[Alan Etkin]

Updated the script to:

- Write port 443 admin password
- Create welcome.w2p package (for solving admin create app feature error)
- Patch Python2.7.3 code for sqlite3 issue before installing

It was tested with a clean CentOS 5.8 vbox and is working. Needs 
improvement: it stops a few times for user confirmation

{{if conditionA == True:}}
{{for obj in ListA:}}
{{=obj}}
{{pass}}
{{pass}}



This works fine. Now, if I add another condition to the if statement, that 
I know exists:

{{if conditionA == True and conditionB==True:}}
{{for obj in ListB:}}
{{=obj}}
{{pass}}
{{pass}}



It gives me no output but it definitely should. Am I missing something 
here? I can't see any similar examples in the docs

Are you sure that conditionB is a boolean value? For example, (1 == True) is 
True, but (2 == True) is False.

[adohertyd]

Yes that's correct. The data comes from a radio button so the 2 conditions 
are always true or false (boolean)

Just for laughs you could try

if conditionA and conditionB:

Re: [web2py] if statement with multiple conditions in view

[adohertyd]

Woops! I've done a double check, the results are not boolean. I've assigned 
'Yes' and 'No' to each button. Still though, the error remains. 

{{if conditionA=="Yes" and conditionB=="Yes"}}

returns nothing but 

{{if conditionA=="Yes"}}

returns output. The problem is definitely the multiple condition

Please try: if conditionB == "Yes"

and perhaps: if True and True

(just to make the test case dirt-simple)

[Anthony]

Multiple condition if statements work fine in views. Try:

{{if 'yes'=='yes' and 'yes'=='yes':}}

The problem is likely in your code -- conditionB probably isn't equal to 
"Yes" when you think it is. Perhaps if you show more code we can figure it 
out.

I'm sorry guys I'm an idiot. I've just spotted my mistake in the code. It 
was a naming error leaving ConditionB not being assigned. Sorry for wasting 
your time thanks for the help.

Cool but where do I've request available? It's not at import time but
i've a request object in web2py.py -M -S milo

So when can i know that request is a valid object?

Thanks Niphlod for your help but the workaround of letting staff like
it's now is not feasible or i should wait 2 mins for each shell i open.
The external scheduler can be a solution though. But I want to try this
request method first...

At least for cron jobs, web2py constructs a fake request object. Have a look at 
request.env for some distinguishing characteristics. Maybe request should have 
a documented standard way of determining the source of the invocation.

When you said "worker", I assumed you were using the web2py Scheduler -- is 
that the case? If so, you can put something like the following in the model 
or controller that does the import:

if request.global_settings.scheduler:
[do the time-consuming import]

If you're not using the Scheduler, what do you mean by "worker"?

Re: [web2py] Re: run code only if you are a worker

[Anthony]

In general, have a look at the contents of 
request.global_settings.cmd_options -- it includes the various command line 
options specified when starting web2py.

I was referring of a module in applications/milo/modules that is used in
a applications/milo/models

When the import is done, the request object is not yet created in either
web2py server or shell or worker (web2py.py -K milo)

It gets created elsewhere after. Because after the shell is loaded i've
a request object.

Btw I've fixed my issue using a class like this:

class Tagger(object):
tagger = None
@classmethod
def create(cls):
if not cls.tagger:
import nltk
from nltk.corpus import brown
brown_tagged = brown.tagged_sents()
cls.tagger = nltk.UnigramTagger(brown_tagged)

@classmethod
def get(cls):
if not cls.tagger:
cls.create()
return cls.tagger

When I call Tagger.get() the huge import is executed once only :)

Thanks anyway.

Sorry, it should be request.global_settings.cmd_options.scheduler. If you 
do:

python web2py.py -K milo

Then in the model where you important and instantiate the Tagger object, 
the request object will be available, and you should be able to do:

if request.global_settings.cmd_options.scheduler:
[do the import]

In that case, the import will only happen with the -K call.

[web2py] Re: web2py on appfog

[spiffytech]

Followup:

I contacted AppFog support via their live chat to get a few questions 
answered:

   - Confirmed: You can't buy more storage (yet). It's a priority for them, 
   though.
   - An app's instances don't all see the same copy of the filesystem. 
   That's less of a problem than the fact that:
   - Your writable filesystem isn't persistent. AppFog recommend it be 
   devoted strictly to your codebase, with any static assets being placed on 
   something like S3.
   - Confirmed: They don't provide cron. I attempted to use web2py cron in 
   my AppFog app, but I can't make it work. I haven't tried very hard to 
   figure out why.

I was also able to get my app running on their Rackspace instances- it 
seems their `af` command doesn't work right with the --debug flag, which I 
was using to see why things weren't working :P `af start ` worked fine.

Lastly, the Apache Benchmark numbers I presented last time lasted through 
at least Monday night. When I tested tonight, they had fallen to around 1 
second average load time- far more reasonable. I asked AppFog support about 
the high load times last weekend, and they couldn't pinpoint a specific 
issue, but said they had been fiddling with things in response to opening 
to the public and I might have just caught them at a bad time. I'll give 
them the benefit of the doubt on that, but I'd still keep an eye on those 
load times for a while before assuming an app will perform reasonably on 
their service. 

So, now that I got a Rackspace deployment working, and their hosting isn't 
slower than molasses, I'm a little more optimistic about AppFog.

[web2py] GAE Cloud SQL local dev server problem

[Alexei Vinidiktov]

Hello,

I'm need hep figuring out how to set up a local GAE development server with
MySQL.

MySQL connection parameters are specified via App Launcher application
settings: --mysql_user=root --mysql_password=xx --mysql_host=localhost
--mysql_port=3306

When I launch my web2py app with GAE Launcher on my local Windows box I get
this erorr message:


ERROR2012-08-04 06:28:43,515 dal.py:5962] DEBUG: connect attempt 0,

What does the following line do?

self.folder = folder or '$HOME/'+thread.folder.split('/applications/',1)[1]

If I comment out "or '$HOME/'+thread.folder.split('/applications/',1)[1]"
in DAL.py and relaunch the dev server, the application appears to be able
to connect to MySQL but then I get a different error message:

#

The vocabilis database does exist. It was created earlier when I connected
to MySQL from a non GAE environment.

If I specify a different non-existent database in the connection string,
then after relaunching the application vith the GAE Launcher I get this
error message:

###

###

So the application  appears to be unable to create the session table.

I'm running Windows, Python 2.7, web2py 1.99.7, MySQL 5.5
