[T.R.Rajkumar]

Thank you for the reply. I do not know how to code it in a module. Example 
code would be of great help. Is there any example in book?

You can use this for example :

http://www.ibiblio.org/g2swap/byteofpython/read/making-modules.html

And place it in the site-packages or modules/ folder in your application.

Good luck,

[web2py] session less connections

[icodk]

I have many sensors that reports periodically to a web2py application.
The sensors do not need to log in, they just POST a json string to specific 
controller function, get a few bytes in response and close the connection. 
However each time a sensor connect, a session file is generated. This 
create a lot of useless files. Otherwise the site has a standard user 
interface that requires login from users.
Is it possible  to avoid the session creation just for that controller 
function or do I need to make a session less app that update the same 
database ?

[web2py] Re: How to download (zip) file with jQuery ajax?

[Phillip]

I get the same result with the posted function, albeit your nuances 
appreciated.

To be thorough, I'll repost the updated function.

def download_that():

import zipfile

import cStringIO

import contenttype as c

vars = request.vars

tempfile = cStringIO.StringIO()

temparchive = zipfile.ZipFile(tempfile, 'w', zipfile.ZIP_DEFLATED)



fileIDs = vars.values()

try:

for file_id in fileIDs:

file = db.files[file_id].file

fileLoc = db.files.file.retrieve_file_properties(file)['path'] 
+ '/' + file

temparchive.writestr(db.files[file_id].file_name, open(fileLoc, 
'rb').read())



finally:

temparchive.close() #writes 

response.headers['Content-Disposition'] = 
'attachment;filename=files.zip'

response.headers['Content-Type'] = 'application/zip'

rtn = tempfile.getvalue()

tempfile.close()

return rtn

[web2py] Using as_list() as a performance boost

[Vinicius Assef]

Hi everyone.

I'm developping a function that wil be called through ajax and it accesses the 
DB, but I need it to be as fast as possible.

Would I expect the `as_list()` method be faster than the normal `select()`?
