[web2py] Re: scheduled task not committing

[Leonel Câmara]

That's fine Jeremy there's no issue here.

"In models, views and controllers there is no need to ever call commit or 
rollback explicitly."

There's no scheduler mentioned there.

Do note that this is also in the documentation:

Remember to call db.commit() at the end of every task if it involves 
inserts/updates to the database. web2py commits by default at the end of a 
successful action but the scheduler tasks are not actions.

This is basically for the same reason that you need to commit if you do 
this kinds of things in a web2py shell, this is just code running in a 
web2py environment. Lets look at what the book says:

Notice that scripts/functions executed in the web2py environment require a 
manual db.commit() at the end of the function or the transaction will be 
reverted.

[web2py] Re: Running threads in Scheduler process

[Niphlod]

techinically any scheduler worker is a fresh process spawned with 
multiprocessing.Process, so spawning a thread, albeit counterproductive, is 
allowed.
I'm not that sure that launching a process from inside a spawned process 
play wells with input/output buffers. 
In any case, using multiprocessing.Popen spawns a new thread already under 
the hood

Thanks Vinicius,

it worked.

if it couldn't find the value, it raised this error:

 list index out of range

Is the below way acceptable way of preventing the error message? Or is 
there a shorter way?

try:
num_recs = int(grid.element('.web2py_counter')[0].split()[0])
except Exception, e:
num_recs = 0
else:
if num_recs > 1:
response.flash = T('The same zip code exists for more than one 
country. Choose one.')


thanks

You got almost there.

Try this:

num_recs = int(grid.element('.web2py_counter')[0].split()[0])
if num_recs > 1:
response.flash = T('The same zip code may exist for one or more countries')
return dict(grid=grid)

[web2py] Re: IS_IN_DB validation error

['DenesL' via web2py-users]

The second parameter of IS_IN_DB should be a set not a query:

query: (geo_item.f_collection_id == geo_collection.id) 

set: db(geo_item.f_collection_id == geo_collection.id) 


IS_IN_DB(db, db(geo_item.f_collection_id == geo_collection.id 

),...)

Been there, done that. Not so easy to spot.

[web2py] scheduled task not committing

[Jeremy Martin]

Okay, so I have a strange issue. I have a simple database update in a 
function in a file called "scheduler.py" in the "models" folder. When I 
call this function from my website running on Apache, works great, no 
problem. 

However, when a scheduled task runs it (i.e. something like 
"/usr/bin/python /opt/web-apps/web2py/web2py.py -K myapp &" in rc.local on 
centos), the database doesn't get updated. Moreover, if that database 
update runs in a loop, it's only the LAST update that doesn't get committed 
to the database, as if there was an implicit commit before every update 
statement.

My fix is to simply call "db.commit()" after my update, but I don't 
understand why I need to do that. Again, it works great when, for example, 
someone clicks on a link on a webpage, but the same function doesn't give 
the same results when called from the scheduler. The documentation states, 
"In models, views and controllers there is no need to ever call commit or 
rollback explicitly." So I'm puzzled.

per below
TR("Asset Custom

Then i assign the metadata value to a new variable as per below
assetcustomfield = request.vars.metadata

But when i am using this variable to post to a script it creates the 
following quotes around the value as per below
"{'type':'bugs','weight':'250'}"

How can i remove the "" around the variable??

[web2py] Running threads in Scheduler process

[Bilal Hasan]

Before I tested this out (I'm running on production environment), I wanted 
to ask would it be okay to spawn threads in the scheduler function?

Since I need to split some tasks using the Linux command line.

What would be the best way to do this?

Using the threading library? Or just run a bunch of subprocess Popen calls 
and not wait on those to return?

Any help or feedback ointing me into the right direction on how to use the 
scheduler with threads would be appreciated.
Thanks.

[web2py] IS_IN_DB validation error

[John Smidt]

Im currently creating a website for a geology museum. Each exhibit in the 
museum contains different collections (or categories) of minerals, and each 
collection has a handful of individual minerals that are being shown at 
this museum. The part that I am currently working on is to allow an admin 
to select a featured image of a specific item in each collection via a drop 
down box within the collection table. However, the validation of this field 
is acting up. Here is the code:

db.geo_collection.f_featured_img.requires=IS_IN_DB(db, 
(geo_item.f_collection_id == geo_collection.id),lambda row: '%s' % 
row.f_name)

The comparison in this line of code (geo_item.f_collection_id == 
geo_collection.id) is not working, stating that I am unpacking too many 
values. 

Here is the traceback:

Traceback (most recent call last):
  File "/home/SIRI/web2py/gluon/restricted.py", line 217, in restricted
exec ccode in environment
  File "/home/SIRI/web2py/applications/mqr/models/db_wizard.py"

row.f_name)
  File "/home/SIRI/web2py/gluon/validators.py", line 497, in __init__
(ktable, kfield) = str(field).split('.')
ValueError: too many values to unpack


I believe that the tuple "(ktable, kfield)" is the reason why I'm unpacking 
too many values, since it requires one table and one field, and I have a 
table and *two* fields. The question that I have is 
*how can I reference these items in my table without breaking the code?*
Some extra info, I have tried to change the IS_IN_DB to IS_IN_SET, but 
received an error stating that " 'Query' 
object does not support indexing".

Any information would be greatly appreciated.
Thank you,
John

db.define_table('invocados',
Field('modulo_servico', 'string', label='Módulo (Serviço)', 
default=IS_LENGTH(2)),
Field('servico', 'string', default=IS_LENGTH(8)),
   )


*Controller*

fields=(db.invocados.modulo_servico, 
db.invocados.servico)Invocados=SQLFORM.grid(db.invocados.modulo_servico != 
db.invocados.modulo_consumidor, details=False, fields=fields, 
groupby=(db.invocados.modulo_servico | db.invocados.servico) , paginate=15)


I'm trying to count all records grouped by modulo_servico and servico. I've 
tried:

fields=(db.invocados.modulo_servico, db.invocados.servico, db.invocados.count())

but it doesn't work.


Can somebody help?

[web2py] how to get count (number of records) from grid.element('.web2py_counter')

[Alex Glaros]

how to retrieve the number records in grid.element('.web2py_counter')?

I'm looking for something like
if grid[0][0] > 1:
response.flash = T('The same zip code may exist for one or more 
countries')

Thanks,

Alex Glaros

[web2py] Re: IOError(11, 'Resource temporarily unavailable')

[Calvin]

I have an error handler within web2py that provides the error trace. 

One hypothesis offered was that nginx is closing the socket as uwsgi is 
taking too long to serve data. I've increased the keepalive_timeout 
parameter from 60 to 600 but this does not help. Where else could the 
problem be?

[web2py] Re: console.log on page reload?

[Tom Campbell]

Thank you, Derek, but I'm still flummoxed. I added this new script tag to 
web2py_ajax.html:

console.log('loaded ' + Date.now())

But I'm getting this message even when I use LOAD(). So I'm trying to 
understand whether I am placing this code in the wrong location or what, 
because I think it shouldn't be redrawing the page. The XHR record output 
seems to confirm this.

FWIW the actions are called this way from menu.py:

response.menu = [
('Demo', False, '', [
(T('New task'), False, URL('default', 'new')),
(T('Show all tasks'), False, URL('default', 'all')),
]),
]

You don't need that, just do this...

[web2py] console.log on page reload?

[Tom Campbell]

Working on a single-page app and trying to ensure that only part of the 
page gets refreshed. Doing some tests using LOAD() that look like this:

*file default/new.html:*

{{extend 'layout.html'}}
{{=LOAD('default', 'new.load',ajax=True)}}

*file default/new.load:*

{{if 'message'in globals():}}
{{=message}}
{{pass}}
{{=form}}

I added this detection code to* web2py_ajax.html*:



But the refresh seems to be called every time I choose the action. However, 
when viewing the console output in Chome I get the hoped-for message 
starting with:

RELOADED Thu Oct 01 2015 15:36:45 GMT-0700 (PDT)

etc.

[web2py] Re: how to access external API

[Alex Glaros]

thanks Leonel,  

I get the logic but it didn't work in my configuration, however I'm very 
happy to have it work with the extra "dict" term.  

Appreciate for your patience.  It's my introduction to API and JSON.  

great to have these explanations!

[web2py] Re: how to access external API

[Leonel Câmara]

Alex I think you're slightly confused, let me explain.

This was the original controller function I suggested.

def locateme():
import json
from gluon.tools import fetch
location_data = json.loads(fetch('http://ipinfo.io/%s/json' % request.
client))
return location_data

Note that it returns location_data, what is location data? Well it's a dict 
because that's what the API returns and the json module takes care of that 
for us.

In web2py, controller functions that return dicts make the keys in that 
dictionary available in the view. So in the view you shouldn't be acessing 
location_data directly you should be accessing its keys. 

To further illustrate I could rewrite locateme like this

def locateme():
import json
from gluon.tools import fetch
location_data = json.loads(fetch('http://ipinfo.io/%s/json' % request.
client))
return dict(city=location_data[u'city'], region=location_data[u'region'], 
country=location_data[u'country'],)

But this would be superfluous because location_data is already a dict I can 
perfectly well return.

[web2py] Re: Wizard inside a LOAD

[Niphlod]

proposed fix:

gluon.main : 
just after setting web2py-component-command, set a new 
web2py-component-origaction header = request.url

web2py.js : 
in ajax_page, inside oncomplete, just before web2py.trap_form, handle it

var origaction = xhr.getresponseheader('web2py-component-origaction');
action = (typeof origaction != 'undefined') ? origaction : action;

and it works.
Just for completeness, same type of handling in updatePage to change the 
w2p_remote of the cid to web2py-component-origaction

Of course, this stands as long as there's really no method to extrapolate 
on the oncomplete callback the "final url" that has been loaded, in which 
case, no gluon.main changes necessary.

[web2py] Re: Wizard inside a LOAD

[Niphlod]

umpf. the behaviour is reproducible.
The thing is, handling component redirects with ajax as normal redirects is 
bad because ajax just follow the same convention as browsers and it's 
impossible to intercept a get wich follows a redirect from a normal get in 
any way.

For now the proposed fix/workaround is to pass an explicit _action to the 
FORM, which will prevail if explicitely found.
Its quite easy because _action=URL() gets things done pretty quickly and 
painless.

Now, for the "real fix", we'd have either to add an header to every ajax or 
we won't be able to distinguish a 200 from a 302+200.
I'm open to possible solutions not involving add an header to every ajax 
request.

As Leonel said, you should access it with "city" directly.

This works.  But is it good programming?

in controller, convert into a dict:

location_data = dict(json.loads(fetch('http://ipinfo.io/%s/json' % 
request.client)))

in view:

  {{=location_data['city']}}

sure, it is the same

maybe I need to define the globals or location_data as a dict?

as a work-around, I can read location_data as string, but seems that a
simple answer might be available

I can see that your file is named locate_me.html, is your function
in the controller has the same name ?..

As a learned lesson, you need to make sure of its availability :

{{city = globals().get('city', '')}}

in the view. I guess you will have the same error with the other
variables.

Good luck,

[web2py] interpolate table name

[Anthony]

You cannot treat Python code like a string. In this case, though, you can use 
dictionary syntax:

db[table_name].validate_and_insert()

[web2py] interpolate table name

[Mark Billion]

Following up on my last post--this fails:

db.%s.validate_and_insert(...) %var_containing_table_name

Any thoughts on how to interpolate?

return draw()

[web2py] Re: Migration of java/tomcat backend

[Leonel Câmara]

I definitely think web2py is much more productive than that stack. However, 
it's worth considering if the migration is worth it. In my company we still 
support one app that has a backend like that, I always wanted to migrate it 
because it's the only thing still using Java. Frankly, even though it 
annoys me that I have to keep running tomcat on my server and some Java 
knowledge in my head, I could never justify it because the changes to the 
backend are so rare.  
  
So, really, the first caveat, is it worth it? Are you going to make a lot 
of changes to the backend?  
  
Then, if you'll be migrating one endpoint at a time you will also have to 
deal with routing the requests. You can avoid it completely by running the 
web2py and java versions completely side by side, in different URLs, and as 
the web2py version gains more functionality you can update the mobile app 
to use the web2py version. In a bunch of iterations you would have 
everything converted and you would always be able to downgrade the users to 
the previous version of the app if something went wrong. Of course the 
better option, if you have people experienced configuring the webserver or 
you're willing to learn, is changing the webserver config so that the new 
requests for a given endpoint go to web2py without any changes to the 
mobile app, which is preferable as it's much faster to switch back if 
something goes wrong.   
  
Another thing to watch for are table migrations, make sure to have them 
disabled as you probably don't want web2py changing the tables for the 
application during this transition phase.

Good luck!

[web2py] Re: Matplotlib

[Laurent Lc]

I found something :

In a controller (the import is done in a model) :

def mychart():
return dict(a=IMG(_src=URL('draw'+'.png')))

def draw():
x = [datetime.date(2014, 1, 29), datetime.date(2014, 4, 15), 
datetime.date(2014, 3, 29)]
y = [2, 4, 1]

fig, ax = plt.subplots()
ax.plot_date(x, y, markerfacecolor='CornflowerBlue', 
markeredgecolor='white')
fig.autofmt_xdate()
ax.set_xlim([datetime.date(2014, 1, 26), datetime.date(2014, 5, 1)])
ax.set_ylim([0, 5])
body = cStringIO.StringIO()
plt.savefig(body)
return body.getvalue()

View:
{{=a}}

Now how to run this code if put the function draw in a model (as done in 
the examples given)

thank you

[web2py] Re: how to access external API

[Leonel Câmara]

That's not problem in python 2 a string like this u'' just means it's 
unicode you can convert it to utf-8 but there's no need.

If you notice how I do it in my example I use the dict the API returns as 
the dict my controller returns, so you access it's keys directly in the 
view.
