Hi ,
i am a newbie in Web2pyI have more than 1 lakh records in database
table1 and i am displaying that table through an SQLFORM.grid.The problem
is the corresponding WebPage for this table1 is taking more than 15 seconds
to open.Is there a way we can solve this performance issue??.Kindly
help..
Default.py

[web2py] Re: Converting Field of a SQLFORM.grid to local timezone of a user.....

User will set the timezone offset in table x, for a particular name. There
is one thread continuously running in background in the server which will
save the servertime as local time using datetime.datetime.now() in table y
for the name.
And finally this data displayed by using SQLFORM.grid on the UI.
Problem facing:
We have to convert the local time saved for the name field as per saved
timezone_offset in x table and display on the grid without modifying
anything on database level.
It means suppose for name ='Alex' timezone_offset was being saved as -5 in
x table and suppose server running on different timezone lets say on +5.30
so for name Alex server will save the servertime in +5.30 format as it is
the local time for the server but when it will be displayed on the
grid servertime should first get converted to Alex timezone_offset which is
set as -5 and then display on the grid.
Can anyone please suggest me how can I achieved in web2py? Is there any way
to achieve it using SQLFORM.grid()?
Thanks.

[web2py] Converting Field of a SQLFORM.grid to local timezone of a user.....
Hi, I have a table x, with fields name,place,timezone offset.And another table y which references to table x and has an additional field 'timezone',which displays the timezone of the server its fetching the values from.I want to convert the timezone of the server,to the timezone of the local user,by using the offset of from table x,Kindly suggest a way to show the converted time in a grid,such that we don't have to convert for all the records in the table y.Only the shown page records should be converted .Converting all the records might slow the process.So,one page will have 20 records,all the records its displaying should be converted to user's local timezone.When the user, paginates to another page,those 20 set of records shuld be converted that moment and shown.Is it possible.Kindly tell a way if this can be achieved. -- --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

Re: [web2py] Create SQLFORM with one of its field's as ajax enabled
Hi Richard,
Thanks for the answer.
Actually i am able to achieve Ajax enabled text box in an
SQLFORM...But the problem is the sqlform is auto generated by the
SQLFORM.grid for that database.
The code for SQLFORM which is working for normal tables is:
DB.py
db.define_table('tag',Field('name'),Field('campus'),Field('timezone'))
def tag_data():
result = {}
result['name'] = 'Neha'
result['campus'] = 'Orion'
result['timezone'] = 'America/newyork'
db.tag.insert(**result)
db.commit()
db.define_table('timezone_list',Field('countries'))
def timezone_list_data():
result = {}
result['countries'] = 'Ireland'
db.timezone_list.insert(**result)
db.commit()
def timezone_bulk():
db.timezone_list.bulk_insert([{'countries':'Africa/Abidjan'},
{'countries':'Africa/Accra'}, {'countries':'Africa/Addis_Ababa'},
{'countries':'Africa/Bamako'},{'countries':'America/Argentina/Buenos_Aires'},
{'countries':'America/Argentina/ComodRivadavia'},
{'countries':'America/Argentina/Rio_Gallegos'},
{'countries':'America/Cambridge_Bay'},{'countries':'America/Chicago'},{'countries':'America/Costa_Rica'},{'countries':'America/Detroit'},
{'countries':'Indian/Antananarivo'},{'countries':'Indian/Mahe'},{'countries':'Indian/Maldives'},{'countries':'Indian/Reunion'},
{'countries':'US/Hawaii'},{'countries':'US/Pacific'},{'countries':'UTC'},{'countries':'Zulu'},
{'countries':'Singapore'}])
db.commit()
DEFAULT.py
def month_input():
form=SQLFORM(db.tag)
return locals()
def month_selector():
if not request.vars.timezone:
return ''
pattern = request.vars.timezone.capitalize() + '%'
selected = [row.countries for row in
db(db.timezone_list.countries.like(pattern)).select()]
return ''.join([DIV(k,
_onclick="jQuery('#tag_timezone').val('%s');
jQuery('#suggestions').hide(); " % k,
_onmouseover="this.style.backgroundColor='yellow'",
_onmouseout="this.style.backgroundColor='white'",
).xml() for k in selected])
def timezone_list_dataF():
timezone_list_data()
def timezone_bulkF():
timezone_bulk()
month_input.html
{{extend 'layout.html'}}
{{=form}}
#suggestions { position: relative; }
.suggestions { background: white; border: solid 1px #55A6C8; }
.suggestions DIV { padding: 2px 4px 2px 4px; }
jQuery("#tag_timezone").keyup(function(){
jQuery('#suggestions').show();
ajax('month_selector', ['timezone'], 'suggestions')});
But i have to generate the same result for an auto generated
SQLFORM.Actually we are using an sqlform.grid which has an inbuilt option
for ADD.And on clicking on that an autogenerated SQLFORM for adding inputs
opens.Now the goal is to add another field in that page which is ajax
enabled.Can we do it?.Kindly helpThanks in advance..

def initNewLines(self):

''' given a string return a list with the indices of each \n character

result = []

But it still doesn't seem to work. If I change it to self.newlines = [],
web2py pickles the session fine.

When I visit the controller pages, the entries are properly added and retained. When I call via AJAX, the entries are not, despite being added locally (eg printing the elements to console after adding). I thought it might be that I am trying to add request.vars in the ajax call, but it doesn't remember even string literals being added. Confused... ahhh... But when I add another (primitive) variable to the session and change that within the (server side of the) ajax call everything starts working properly. So, presumably web2py doesn't notice changes to the instance so chooses not to update session, changing the primitive causes it to update all the session variables including the instance.

The class I have been testing is supposed to accumulate elements like a set. The first one I add (in the controller for the view for debugging) gets stored in the instance fine, and it seems to persist when I save the instance to session. However, when I add other elements (in a separate function called by the javascript) to that instance they get added while in the function, but don't seem to persist in the object saved in the session. It is like the instance is a local variable initialised from what is first stored by the controller.

[web2py] Storing class instances in sessions... or somewhere
I have an existing application that I am trying to get running as AJAX with web2py (locally, but eventually to run on GAE). The application makes use of class instances to store much of the data which would be used for user sessions. I understand that session can't be used to store class instances but for the time being I want to keep the instances for each session (about 200K of data). Sooner or later I guess I will need to save this data in the data store, but at the moment I'm trying to get a prototype up and running and reworking the code to get the data into/out of a database is more pain than I can face atm. The instances are pickleable (well, cPickle doesn't complain) My options seem to be: * cache in ram using the session id as a key and * dumping the instance to a string, saving the string to session (on GAE will this be the same as cache.ram?) Are there other approaches? What's the best way to go about this? Also, in the next update of the documentation, this would be a useful detail to include on the session related sections. Thanks in advance Brendan

When I try to hook up web2py: python2.5 dev_appserver.py web2py the app starts, but fails when I load the page in a browser: ERROR2011-03-23 23:00:16,549 dev_appserver.py:3285] Exception encountered handling request Traceback (most recent call last): File "/data-current/programming/python/gae/google_appengine/google/ appengine/tools/dev_appserver.py", line 3245, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict) File "/data-current/programming/python/gae/google_appengine/google/ appengine/tools/dev_appserver.py", line 3186, in _Dispatch base_env_dict=env_dict) File "/data-current/programming/python/gae/google_appengine/google/ appengine/tools/dev_appserver.py", line 531, in Dispatch base_env_dict=base_env_dict) File "/data-current/programming/python/gae/google_appengine/google/ appengine/tools/dev_appserver.py", line 2410, in Dispatch self._module_dict) File "/data-current/programming/python/gae/google_appengine/google/ appengine/tools/dev_appserver.py", line 2320, in ExecuteCGI reset_modules = exec_script(handler_path, cgi_path, hook) File "/data-current/programming/python/gae/google_appengine/google/ appengine/tools/dev_appserver.py", line 2216, in ExecuteOrImportScript exec module_code in script_module.__dict__ File "/data-current/programming/python/gae/web2py/web2py.py", line 9, in os.chdir(path) AttributeError: 'module' object has no attribute 'chdir' Any ideas on what's going on/how to fix? web2py version is most recent stable from the website this morning (1.94.5) Python version is Python 2.5.5 (r255:77872, Mar 24 2011, 09:36:33), but I get the same failure using python2.6 Brendan
[web2py] Help with setting up Web2py environment
Hi I have migrated an existing application onto web2py as a proof of concept and I'm looking at how I take it/web2py further. The main things I'm wondering about are: * what's the right way to do logging in web2py? My test server is running apache2/wsgi. * what's the right way to use svn (do I just import the whole web2py directory structure)? * what's the right way to debug applications? python web2py.py -S ? * is Eric useable as an ide? * any traps for young players? Thanks in advance Brendan

[web2py:20706] Re: forms in web2py
I think I've messed it up. I would like to explain my problem once
again clearly.
in controllers/identity.py:
def getcities():
citystr = request.vars.values()[0]
if citystr == "Delhi":
output = "city1, city2" # list
elif citystr == "Tamil Nadu":
output = "city2, city3" # list
elif citystr == "Andhra Pradesh":
output = "city4, city5. city6" # list
else:
output = "Bombay"
return output
def index():
form=FORM(TABLE(
TR("State:", SELECT("Andhra
Pradesh","Delhi","Tamil Nadu",_name="States",
_id="States",default="Andhra Pradesh",_onchange="ajax('/Test/default/
getcities',['States'],'handle')",requires=[IS_NOT_EMPTY()])),
TR(DIV(_id="handle")),
TR("District", SELECT({{=handle}}, _name="Choose",
_id="district", default="", requires=[IS_NOT_EMPTY()]
return dict(form=form)
What i'm trying to do here is: I've built a form to enter the states
and based on the option selected by the user, I'm generating another
option list. So in the first options menu, the user input will be sent
to geticities() function using ajax which will return a json object
list of cities beloging to that input entry. Now when I use that list
(handle) in DIV tag, I'm able to display list. But I'm not able to use
that list to populate the options in second SELECT tag as shown above.
Its giving me an error on writing so. Had i written that code for the
form in a View using html, i wud not have faced these problems. Since
I'm using the SELECT tag here, I'm facing these problems.

[web2py:20506] Re: forms in web2py
in Controller/index.py:
def getcities():
citystr = request.vars.values()[0]
if citystr == "Delhi":
output = "Hyderabad"
elif citystr == "Tamil Nadu":
output = "Chennai"
elif citystr == "Andhra Pradesh":

TR("District", SELECT("","asfas","safee",
_name="Choose", _id="district", default="", requires=[IS_NOT_EMPTY
()]
return dict(form=form)
This is how i've written a form with ajax to auto-populate SELECT
boxes. But in the above code, if i want to use the "handle" variable
and display it as an option in SELECT box, I'm not able to do that. If
i return a list into the "handle" variable then how do i populate the
list in SELECT box. Please reply me asap.
Thanks,
Nazgi.
