[web2py] LOAD form deferred by jQuery UI tabs -- how to?
So I'm designing the world's greatest user interface and I happened on the idea of making my numerous SQLFORMs easier to navigate by using jQuery UI tabs and the load ajax feature. Conceptually, what I want to do should be simple. Load the form using =LOAD, but only when the tab is clicked on. When the user clicks on another tab, another SQLFORM is ajax-loaded, and so forth. Both jQuery UI and the web2py LOAD features work perfectly alone. I can even use the LOAD function with jQuery tabs as long as I don't try to use the beforeLoad event to load the form. I just can't figure out the javascript secret sauce to get them to play together. I'm really impressed by the power of the web2py LOAD function. The contributor really knew what he was doing! If I can just understand its underpinnings a little better I can use it for more than the simple case in the book. --

load calls web2py_component(), that is defined in web2py_ajax.js . Look at that if you're looking to an integration with your code.

The easiest way is probably via a custom form:
http://web2py.com/books/default/chapter/29/07#Custom-forms.
Another option -- each table row or div containing a field input has an id
that starts with [tablename]_, so you could use a jQuery selector like:
jQuery('[id^=tutor_]').hide()
That will hide all table rows whose id's start with tutor_, which should
be all the field inputs in the form.

What I'd like to do is hide ALL the elements in the SQLFORM if the
radiobutton is unchecked, and show all the elements if it's checked.
So I have something like this:
script
jQuery(document).ready(function(){
jQuery('#tutor_biography__row').hide();
jQuery('#tutor_is_tutor').change(function(){
if(jQuery('#tutor_is_tutor').attr('checked'))
jQuery('#tutor_biography__row').show();
else jQuery('#tutor_biography__row').hide();});
});
/script
What I'd like to do is not just hide one field, but hide all the
fields if the radio button is unclicked.
Is there a shortcut to do this or must I input all the rows manually?
Also, another thing I'd like to add in the jQuery is, if the radio
button was checked, filled out, and then unchecked, I want the values to
not be stored but to be erased. I assume I'd have to add something like
.val('') but I'm not sure where to do that.

[web2py] About crud.update to edit or update a user's profile info !
Hello web2py users,
I am in the process of completing the edit profile option for the web app
members and I am experiencing a particular problem that is causing me a
headache !
in the profile controller, I am using the following function to update a
user's profile :
def editprofile():
table = db.auth_user
form= crud.update(table,request.args(0))
return dict(form=form)
and in the view, just to test this function, I am starting out with a
simple view with no customization like :
{{extend 'profile/userlayout.html'}}
h4This is editprofile /h4
{{=form}}
in db.auth_user there is the picture or avatar for the user among other
fields
First observation ) When a user updates his profile, all other fields gets
updated ... except the picture field ! ???
Second ) the fields that used checkboxes as widgets when the user was
registering on the site do not show as checked on the edit profile view !
So :
the user's profile keeps the old picture and old thumbnail even after
uploading a new one to replace the old
the new picture uploaded does not even make it to the table nor to the
upload folder ! ... however, I do get the message that the uploaded pic was
re-sized but ... it is not there !
and I wish to have that same picture to show up on the edit profile page
before the submit (update) button is pressed !
And why doesn't the checkboxes show their status or value when in edit

any assistance on this will be greatly appreciated !

[web2py] Re: LOAD form deferred by jQuery UI tabs -- how to?
The LOAD helper simply generates HTML like the following: script type=text/javascript!-- web2py_component(/test/comment/post.load,c282718984176) //--/scriptdiv id=c282718984176loading.../div So, a div with a particular id is created, and the web2py_component() Javascript function (defined in /static/js/web2py.js) is called with the id of that div. Instead of using the LOAD helper, you can manually create a div and set up an event handler that calls web2py_component() when the tab is clicked.

[web2py] Re: Transactions in Web2Py over Google App Engine.
I found this: https://developers.google.com/appengine/docs/python/datastore/overview#Cross_Group_Transactions For example, to increment a counter field in an object, you need to read the value of the counter, calculate the new value, and then store it back. Without a transaction, it is possible for another process to increment the counter between the time you read the value and the time you update it, causing your application to overwrite the updated value. Doing the read, calculation, and write in a single transaction ensures that no other process can interfere with the increment.

Put everyone in the auth_user table and use groups. That could save you
heaps of time down the line. Otherwise I can imagine you'll start
reinventing what's already available to you in web2py. Use the framework
and the force will be with you!
If you need to keep lots of different info depending on what group they are
in, then you can always think about splitting that into different tables,
but only as a last resort.

if form.accepts(request.vars,session):
open(os.path.join(request.folder,'uploads','filename.wav'),'wb').write(form.vars.myfile.file.read())

{shutil.copyfileobj(request.vars.myfile.file,open(os.path.join(request.folder,'static','filename.txt'),'wb'))},

with small files it works, with a 200mb file it gives an error.
Anyone can help me understand this problem? The max file size I need to
upload is 500mb. It will be used by only one person, with a login, so there
is no need to a complex mechanism, and files need to mantain the same name.
I just need the upload to work.

Unfortunately when I submit one of the two forms, all the values are deleted and apparently there is no submission. If then I submit that form a second time, it seems to work. The problem is for sure related to the presence of two components, since if I embed just one of them everything works fine. Am I missing something? Cheers, David --
Re: [web2py] Re: About crud.update to edit or update a user's profile info !
thank you for the response Massimo, I do agree with your thoughts regarding the vulnerability exposed upon a new registration ! that can easily be arranged by adding an additional table to manage all users profile pics ! ... that way, a user can only upload his avatar ( or picture ) only when they are already registered and when they decide to edit their profile, they will be able to upload their own pic ... However, I still foresee the same problem, when it comes to edit that profile pic, with the crud.update for that eventual userimage table that will referenced the appropriate auth_user table record... I come to realize that there are many issues or challenges regarding pictures, uploading pictures, *viewing pictures upon uploads before submitting or updating a form (or crud)* etc .. throughout the web2py forum This is a matter that needs to be addressed head on, through a slice or a how to article, we know that it certainly involves ajax ... but many before me had experienced that problem and though out this web2py user forum, no effective solutions or how tos really stands out .. there is no solid approach to this ! .. if there is one, then I have not found it ! ...or if someone knows ... please point me in a that direction ! Can someone stand up take the time and share or write a good slice about this ! ... a lot of users will benefit from this ! .. the few slices that exist about file uploads and ajax are not well explained or outdated or simply do not work ! thank you Don --
Re: [web2py] Two components + two forms
Do the two components point to the same action, or do they contain forms with same formname? Either case that would not work because multiple forms in the same page must have different formnames?

[web2py] Re: SQLFORM.grid and classes on GAE
this seems to me like a bug in polymodel on GAE. my guess is that the
proper implementation would be to have 2 tables, location_outdoor and
location_indoor in the GAE database. does this seem correct to you?
i can't guarantee my speed right now...but i can look into the DAL and see
if i can find a problem with polymodel on GAE. can you file a ticket in
google code as well so we don't forget?

HI cfh
You're right. As far as I can see in the datastore viewer there is only
one table. There is also a class value available.
I did try a few more things (resetting local datastore and removing the
entries in index.yaml) but I'm not able to access all three tables using
the following controller:
@auth.requires_signature()
def form():
table = request.args(0)
if not table in db.tables(): redirect(URL('error'))
db[table].id.readable = False
form = SQLFORM.grid(db[table],args=request.args[:1],
user_signature=True)
return dict(form=form)
When I do call
http://localhost:8080/init/location/form/location_outdoor?_signature=xxx'
I receive:
AttributeError: 'location' object has no attribute 'country'
When I call
http://localhost:8080/init/location/form/location_indoor?_signature=xxx'
I receive:
AttributeError: 'location_outdoor' object has no attribute
'location_outdoor'
Right after resetting the datastore I'm able to access 'location,
'location_outdoor' and 'location_indoor'. Once I create an indoor or
outdoor location I'm not able to access the other form anymore. The
'location' form is still available.
I'm trying to store all location information (outdoor / indoor) in one
polymodel. I do want to take advantage of having to have only one reference
between devices and locations.
Any suggestions?
Greetings

about that last one, when you access the GAE datastore viewer (as provided
by GAE), what is the name of the table/model that is stored there? does it
store location_indoor and location_outdoor, or just location with optional
fields? (i'd personally expect the former, but your experience sounds like
the latter).
for your other questions see the example under this heading

- Is there a way to create a generic controller (using SQLFORM.grid)
which is able to create outdoor or indoor locations (display either
location_outdoor or location_indoor fields)?
I'm thinking of a select field where I can select the class. Depending
on the class it will show the available fields.
I should be able to modify the SQLFORM.grid to get view and edit
operations to use the correct class. But what about the create operation?
- How can I add an extra field to the SQLFORM.grid view form which
displays the location? I would like to add a field which does contain a
generated QR-code.
- Why are the indexes in index.yaml always called location and not
location_outdoor and location_indoor? I'm often receiving the error
message that location_indoor does not contain 'city', which is true.

Another option -- each table row or div containing a field input has an
id that starts with [tablename]_, so you could use a jQuery selector like:
jQuery('[id^=tutor_]').hide()
That will hide all table rows whose id's start with tutor_, which
should be all the field inputs in the form.

Is there a shortcut to do this or must I input all the rows manually?
Also, another thing I'd like to add in the jQuery is, if the radio

to
not be stored but to be erased. I assume I'd have to add something like
.val('') but I'm not sure where to do that.

[web2py] Bug when rendering nested dictionaries as JSON? -- depends on specific values of keys
I've found a strange behavior in 1.99.7 (which is the same in 2.2.1 except
for a code cleanup issue). This is either a bug or I'm confused (don't
rule that out). This is a long message -- I thought it was important to
include a detailed demo of the phenomenon.
The idea of generic views is wonderful -- a controller function can return
a dict; and based on the extension used to request the page, data is
returned using the formatting logic of the generic view of that type. This
works well and is demonstrated clearly in section 10.1.1 of the book. A
simple example:
In default.py
def test():
return dict(status='200 OK')
Then from a unix command line
$ curl -L 'http://localhost:8000/default/test.load'
200 OK
$ curl -L 'http://localhost:8000/default/test.xml'
?xml version=1.0 encoding=UTF-8?documentstatus200 OK/status/
document
$ curl -L 'http://localhost:8000/default/test.json'
{
status: 200 OK
}
## note in JSON, I made a change in gluon / serializers.py to add indents
So far so good. But something bad happens when the dictionary is nested:
In updated default.py
def test():
return dict(response=dict(status='200 OK'))
requesting ...test.json creates an error file in my app/err folder
Traceback (most recent call last):
File /Users/chris/dev/hsmaster/web2py_v1.99.7/gluon/main.py, line 508,

596, in run_view_in
badv = \'invalid view (%s)\' % response.view
AttributeError: \'dict\' object has no attribute \'view\'
Observations
The book says Any dictionary can be rendered in HTML, XML and JSON as long
as it only contains python primitive types (int, float, string, list,
tuple, dictionary). so this seems in-bounds. json.dumps (serializer
users) has no problem with nested dicts.
This may be a clue -- if we service-enable the same function and call
differently ...
@service.json
def test():
return dict(response=dict(status='200 OK'))
... the result is fine ...
$ curl -L 'http://localhost:8000/default/call/json/test'
{
response: {
status: 200 OK
}
}
or if we don't service-enable it, call like we did the first time, but
change the name of the top-level key like this:
def test():
return dict(blahblah=dict(status='200 OK'))
... the result is fine too ...
$ curl -L 'http://localhost:8000/default/test.json'
{
blahblah: {
status: 200 OK
}
}
Conclusion
After a long Wingare debugging session, I think this code is the proximate
cause of the problem:
in gluon / main.py / serve_controller():
...
page = run_controller_in(request.controller, request.function,environment
)
if isinstance(page, dict):
response._vars = page
for key in page:
response._view_environment[key] = page[key] ### AAA
run_view_in(response._view_environment)
page = response.body.getvalue()
...
Basically it appears that the line marked AAA overwrites data in the
response._view_environment structure with data from the dict the test()
function returns. The problem only happens when a key in the top level
(not nested) of the dict matches an existing key in
response._view_environment. response._view_environment has 129 keys: A B
BEAUTIFY ... auth cache crud ... response request service etc.) and when
one of these is in common with the dict being rendered, the value of
dict[key] overwrites it.
The traceback above was from gluon / compileapp.py / run_view_in() -- that
relies on response._view_environment['response'] to have a key 'view',
which is present before line AAA; but gone after
-- response._view_environment['response'] has been clobbered.
Remediation
In my debugging, I changed line AAA to be a pass statement and nothing bad
happened. I don't know if that is the right approach or not. The same
little block of code I showed above (from main.py) also occurs twice in
compileapp.py. I don't know enough to judge whether eliminating line AAA
as I did is a good idea or not; or if it should be done in some or all of
the three location.
Request
Can someone say if my solution is on the right track; and why the dict is
being merged with the response? Maybe the right approach for a different
payload -- but dicts can't avoid using these keys. view, title, status, db
-- these are pretty common keys.
Best regards and thanks --

[web2py] Re: Why does 'group' field cause web2py to stall?
That name is probably a reserved word in the database engine you're using.
Every DBMS has a list of words that are off-limits for use as object
(table, field, index, function etc.) names. GROUP is a pretty common one
because of the GROUP BY operation. Take a look at gluon /
reserved_sql_keywords.py for a list per DBMS.
If you care about DBMS portability, a good practice is to instantiate your
DAL object with option check_reserved='all' -- this will prevent you from
using table / field / etc. names that conflict with your current DBMS or a
future one you may move to someday (one of the reasons I really like web2py
-- have moved between 4 DBMSs with no code changes!)
