[web2py:32455] Re: Newbie Question: Storing things in the the Session

[portly.shor...@googlemail.com]

Hi

yet again - many thanks for this. I now realise the difference in the
queries (that [0]).

Ah well, I'm learning Web2Py slowly but surely.

I must say that I'm very impressed with the prompt response
(especially for what is probably a very basic question).

Keep up the good work

cheers

[web2py:32454] sqlform using already existing tables...

[Arvind]

Hello,

I have already defined tables in a database.
I need to generate forms using sql form
in my code

db = DAL('sqlite://db.db')

db.define_table('logina',
Field
('uname',requires=IS_NOT_EMPTY()),
 )
It complains duplicate field uname.

If I create a new db, then it works fine by creating a database and a
table with that field. At this point, I can see that it makes a  file
in the database directory with that field description.

How can i use an already existing table ? I dont want to define a
table. just reuse the table.

thanks
Arvind

Ya, I downloaded many times, but still can't get it working.
Btw, 2 weeks before when i checked out the svn, it was working, but
later when i updated the svn, admin page showed the Internal Error.

And also 1 more problem I m having is, Opera shows the welcome page in

I updated and get this MySQL error on an inner join:
OperationalError: (1054, "Unknown column '8L' in 'where clause'")

request.args(0) is 8.  If I change request.args(0) to 1, the error
changes to:
OperationalError: (1054, "Unknown column '1L' in 'where clause'")

...and so on. Hope that makes sense. Using sqlite seems to work.

There is lots of new stuff in trunk, in particular in sql.py.

Hi John,
for now, it'll be too dificult to adopt this URI schema since we have
wiki hosted in different server than site.
In a near future we'll have only one server to host all web2py-related
apps so we can change URIs.
Yeh, cool URIs don't change...and I know that wiki.web2py.com isn't a
cool URI - so it'll change. :-)
But you can rest assured that I will place the redirecting "HTTP Moved
Permanently" when do it.

Thanks for that.

 Great work.

Just a small suggestion to remain in line with current wiki practices
that would make potential adopters less nervous.

There are good sound practical reasons to to make the wiki appear to
live off a directory that is part of the URL. For example
http://wiki.web2py.com/wiki. I know it looks ugly and redundant but it
is sound.

http://wiki.web2py.com could be made to redirect to http://wiki.web2py.com/wiki

This is from http://www.mediawiki.org/wiki/Manual:Short_URL

I like the way dokuwiki[1] gives with that.
It'll be nice to generate LaTeX. :-)

Do you have interest on implementing this feature? It is free

Here's my cut at a patch to return proper headers for css files. This  
does not address Eric's desire for a single controller solution for  
CSS files, which is a different issue, but it does eliminate the need  
for the __cssheaders() function.

 By the time the controller runs, the response has been set up as a
 standard html page. So we delete cookies and the default caching,  
 and
 use Expires caching (an hour as shown) so that, in theory anyway (I
 haven't tested this against browsers yet) the performance should be
 fairly close to static.

[Richard]

is that the proper way to do it, having a separate controller for each
operation? The routes approach sounds more flexible.

I think we have to distiguish:
Books and documentations.
docs are part of the code in soem way. should be easy, short, 
straightforward. should be included in the VCS.

Yes, if Alvaro would create a Sphinx sandbox on his box we could even 
use web2py to edit the Sphinx doc and the docstrings online.
like the numpy community.

I helped Bruce setup access lists in Moin, and I think this would be a nice
concept for this / "our" wiki:

ACL lists held in a page, so that people can be added by  people with
permissions - in Moin, I setup a Admin ACL, and a "CONTRIBUTOR" ACL  (admins
can edit either; contributors can edit pages / chpaters - a way to assign
sections for at least places where you want to generate a Sphinx doc - html
or LaTeX).

Just some thoughts...

That's correct - there was something I didn't like about how it was layed
out, and wanted it simpler - started changing things, then got layed off, so
just stopped thinking about it for the summer.
However,  I have recently seen that Bruce Eckel is thinking about using
MoinMoin for contributions to Python Pattersn & Idioms (people seemed ot
have a hard time ??? with editing Sphinx - though I can't imagine why - it's
the simplest basic thing to me), and I thought about how - with cron - that
a web2py reST blog would be a nicer solution (since Sphinx generation /
"publishing" could be done w/ cron).

In any case, one fundamental thing the blog would need is a "publish" state
for pages,  some way to "ignore" (at least) sphinx-specific markups, and a
way to generate a sphinx doc from a tree.

Sphinx has bugs?  the web2py sphinx has problems?  Not sure what you are

Sure:

Worksheet returns a single row - hope this helps. I'm really keen to

Hi Alvaro,
if you need help with the sphinxification send me a mail.
My current web2py project got stalled somehow. Therefore, please send me 
a direct mail if you have special questions to documentation. I am not 
readying this list every day.
Yarko wanted to add some docstring specs, but he hasn't made it so far.
The Sphinx-Project got stalled due to some bug/problem in the API doc 
generation.
I will try to trace it with the Sphinx project.

Many thanks for such a quick answer. A second question (if I may). I
have a second query that returns a single row - how would I store that
in the session as trying as_list gives me an error:

KeyError: 'as_list'.

many thanks (again).

p.s I've bought the PDF of the second version of the book but could
not find it in there.

[web2py:32424] Re: Why does this NOT pass validation? (bug?)

[mdipierro]

correct. multiple is intended to be used for reference fields that
store integers. You can replace:

IS_IN_SET(('Glasses', 'Soft Contacts','Hard Contacts', 'Other',
'None'))

with

IS_IN_SET(range(4),('Glasses', 'Soft Contacts','Hard Contacts',
'Other'))

None should not be an option becase you can select none of the items.

[web2py:32423] Re: form.custom.errors.field

[mdipierro]

Hi Thadeus,

we just need to talk about this more and get more opinions. I can be
convinced. The code you proposed does not show errors by default any
more.
That is a break of backward compatibility.

You also assume that people who do not want to display the default
errors would use one DIV for each error. Perhaps or perhaps not.

How about a new flag like

form.display_errors=True or False

and if false you can do {{=DIV(form.error.fieldname,_class='error')}}
in code?

[web2py:32422] Why does this NOT pass validation? (bug?)

[Thadeus Burgess]

It seems as if there is a space in the text, then it will not pass
validation if one of the options with a space is selected.

def test():
form = SQLFORM.factory(
Field('field', requires=IS_IN_SET(('Glasses', 'Soft Contacts',
'Hard Contacts', 'Other', 'None'), multiple=True, error_message="Must be in
set"))
)

if form.accepts(request.vars, session):
response.flash = "Accepted"
if form.errors:
response.flash = "Errors"

return dict(form=form)

[web2py:32421] Re: FORM factory

[Russell]

Personally, I like the way the widget renders the error by default -
it's pretty tidy and does what you want most of the time.  If you want
to remove the error from the widget you could look at the section
called "Switch off errors" on page 220 of the manual.

[web2py:32420] Re: form.custom.errors.field

[Thadeus Burgess]

But I do want to display errors... just not where web2py insists they
display.

And I think there is a solution here that will satisfy everybody, that kind
of thinking is NOT good for the growth web2py!!!

I am just not familiar enough with the base code, but I suppose I will get
familiar with it to find this solution that will satisfy everybody.

If you do now want to display errors automatically do

[portly.shor...@googlemail.com]

Hi - I am new to Web2py and think it is great but I'm stuck. Is there
a limit on what i can store in the Session? I want to store the the
results of a sql query (returning 40 records) in the session. When I
try I get an exception:

Traceback (most recent call last):
  File "gluon/main.py", line 419, in wsgibase
  File "gluon/globals.py", line 368, in _try_store_on_disk
  File "copy_reg.pyc", line 73, in _reduce_ex
  File "gluon/sql.py", line 537, in __getattr__
KeyError: '__getstate__'

any ideas?

many thanks

Portly

It was:

The idea of microapps on top of microblog engines is some kind of 
"cyborg approach". We can build a wrapper on top of any infraestructure 
and replace with progressive layers down to the base as we progress, so 
we can, for example, extend django powered jaiku engine with web2py.

Cheers,

[web2py:32413] go to different page on submit in T3

[Wes James]

I can see how to use onaccept/redirect to a different page standard
views and controllers, but with t3 how is this done?

Editing a T3 page, say you have:

{{=FORM( INPUT(_type='submit', _value='search'))}}

How would you submit to a different page.  By default it comes back to
the same page.

30 seconds later.

wait, never mind I just used {{=FORM( _action='next-page')}} and that worked

thx,

[web2py:32412] form.custom.errors.field

[Thadeus Burgess]

I am attempting to patch web2py to allow support for custom errors in custom
forms, so that the widgets to auto magically render the errors when using
custom form.

Desired functionality should behave such as "{{=form.custom.errors.field}}"
and would display "must contain a
value!"

The below patch provides this functionality, however, when using regular
form, it will not render the error div.

Perhaps there is a less intrusive method? Something that will still work
with just calling {{=form}}

I would think that the new errors DIV would need to be appended to the
components of the SQLFORM?

Could someone with more knowledge of the web2py innerworkings help me with
this?

[web2py:32410] Microapps on microblogs using web2py + OAuth (the cyborg approach for apps)

[Offray Vladimir Luna Cárdenas]

Hi all,

There is an idea about using small apps that can be created on top of 
microblog engines[1]. I would like to create that apps in web2py. The 
specific idea is to enrich a microblogging engine putting 
metainformation on messages to make it more accurate in educative 
context in similar way to what philtro[2] does for twitter. The idea is 
to get statistics, richer tags an even another interface. We tested 
several open source  microblog engines like Jaiku (which runs on top of 
the restrictive GAE --exclusion by countries, powered by google) and 
Yonkly (but running asp.net + SQL Express on Linux was the long way to 
go), so, for the moment, we're using present.ly as a microblogging app, 
because is the one with most of the features we want, the best user 
interface and has and API made using OAuth[3], so we can taker care 
about of things like data portability and other issues of a free/open 
web. The idea of microapps on top of microblog engines is some kind of 
cyborg approach. We can build a wrapper on top of any infraestructure 
and replace with progressive as we progress, so we can, for example, 
extend django powered jaiku engine with web2py. I previously had made 
some attempts to start with web2py, but this is the one that seems more 
interesting to me so any pointer about this idea would be appreciated.

You're welcome.

I think it's a generally useful capability, and I hope that there's a  
more elegant way of incorporating it into web2py. As I was saying  
somewhere else, a generic.css file doesn't really work (unless you're  
generating all your CSS content in controllers). At the very least,  
perhaps the logic (where?) that creates the default html headers could  
recognize that it's got a .css file and create css headers instead.

 When I tried serving dynamic CSS (I wanted to dynamically control

[web2py:32403] Use existing database tables?

[snorkel]

Hi,
I have a application currently in PHP and already have PostgreSQL
tables etc setup for it, is there a way to
effectively use web2py to create a new front end using a DB pool from
the dbutils package and use that pool from
a controller?   I don't want to create new models for the database.

I am currently using Pylons, but web2py looks a lot easier to use.

Thanks,

Snorkel

[web2py:32402] Re: FORM factory

[Thadeus Burgess]

I have to perform a nasty hack to get around the form.errors displaying on
each radio button!

Make sure to set error_message="". Now it won't display a divs for the
error.

Manually in my view,

{{if form.errors.has_key('field'):}}
You must enter a value into this field!
}}
{{=form.custom.widget.field}}

There has got to be an easier way?

[web2py:32401] Re: URLs in static files

[Julio]

This is good, specially if on your website you implement some sort of
"skinning" allowing the users to dynamically switch "layouts" using
the same css file, thanks for sharing this.

Just visit http://wiki.web2py.com/ register and visit
http://wiki.web2py.com/Page_name_you_want_to_create so post your code
and some comments about.

I should have commented it a bit first, but it's not all that subtle.

By the time the controller runs, the response has been set up as a  
standard html page. So we delete cookies and the default caching, and  
use Expires caching (an hour as shown) so that, in theory anyway (I  
haven't tested this against browsers yet) the performance should be  
fairly close to static.

When I'm actually working on the CSS, I reduce the Expires timeout to  
3 seconds (or whatever you like) so that my changes appear promptly.

Here's a slightly cleaner version:

def __cssheaders():
 '''
 edit default response headers for CSS
 serve text/css with no cookies, limited caching
 '''
 response.cookies = Storage()  # no cookies
 for header in ('Last-Modified', 'Expires', 'Pragma'):
if header in response.headers: del response.headers[header]
 response.headers['Content-Type']='text/css'
 response.headers['Cache-Control'] = 'max-age=3600, must-revalidate'
 response.headers['Cache-Control'] = 'max-age=3, must-revalidate'

[web2py:32396] [New] web2py wiki

[Álvaro Justen [Turicas]]

Hi folks,
I'm posting this to show you that we have a "new" wiki system.
Last weekend I changed some things in wiki app, like:
- Now we have real page names, like http://wiki.web2py.com/Page_name
- Some layout changes
- Simplification of some forms
- Included views that weren't there
- Fixed some bugs

And with Massimo's help we migrated it to my server - and so now I
have more flexibility to update the app.
Please use:
http://wiki.web2py.com/
(instead of http://www.web2py.com/wiki - it actually will redirect to
former URL)

All "active" pages that have links in the old way
(/wiki/default/page/an_ugly_uuid) were changed to new way.
All users are still in the database, none was changed in users' table.

Future plans:
- Move AlterEgo pages to wiki and create a "FAQ" page in wiki with a
list - please don't do it manually, I'll do a script to do this job
(probably next weekend);
- Add more wiki features that we don't have today;
- Better usability;
- Move to BitBucket.

If you want to contribute or use this wiki in your site, just check
out the code in:
https://code.launchpad.net/web2py-wiki/
If you have feature requests, bug reports or other issues related to
this app (like usability, hosting etc.) please let me know.

Let's create the better documentation project of a web framework!
Let's write about web2py! :-)

Thanks,

Yes, you are right. And now that we have this thread, someone how is

At least it should be documented how someone could add countries (it's
a field used a lot)

[web2py:32389] Re: how to import html helpers inside a module?

[Iceberg]

Sorry but IMHO:

1. adding a gluon/contrib/countries.py with a countries_list =
['United States', 'Afghanistan', ...] is good enough for reference,
and developers might change orders or languages before really use it.

2. adding a countries_widget is not that convincing, especially
because it is just one line of code (means not worthy to wrap as a
widget), if we already have the countries_list=[...]

3. adding a Field('country', 'countries') ... mmm... see point #2.

Just my 2 cents.

Yeap, that's the way I was first doing it but I am wondering what must
be imported so module code can work (because it's working when it's in
db.py).
Also, creating a Field('country', 'countries') would be (I think) a
nice addition. Should I submit a patch, Massimo?

[web2py:32380] Re: how to import html helpers inside a module?

[Iceberg]

Since you gonna import one homemade module anyway, why not just:

from applications.yourapp.modules.country import
country_names_as_a_list
db.define_table('shipping_info',
  Field('countries', _requires=IS_IN_SET(country_names_as_a_list))
  ...
  )

This way you don't force yourself to know something difficult (though
not that difficult if you really know widgets well).

I'm going to deploy in GAE, so I don't think https is an option. In
the out-of-the-box web2py passwords are not visible. I would like to
adopt the same but with user name rather than email. Is it possible?

BTW: I am able to get a web2py app pretty quickly; but this auth
customization is what I'm struggling with. Is there any link where it
is explained in detail (like what steps to take)? I've got the web2py
book & slides too.

I notice that if you don't match defined Field in SQLFORM.factory and

The length attribute of Field-string doesn't produce a desired width

[web2py:32377] Re: GAE Tutorial to Web2py

[murray3]

sorry for posting this again but it does not appear to show up in the
list of
postings!

I wondered if anyone had tried to use the xmpp functionality of GAE
for non chat i.e. application communications.

There are a number of ways of doing this using the various javascript
libraries (strophe, jajasc etc) but not sure if they work with
this initial xmpp offering from google? Also Strophe has a django
sample but again not sure if it will work with GAE as it is using
BOSH.

I think this is the future for web apps and it would be great if we
could
get web2py fully enabled to utilise this technology.

[web2py:32376] Re: how to import html helpers inside a module?

[Jon Romero]

ok, I've imported gluon.html but now it seems there is another
different error.

I am creating a country widget (it will display all countries in a
dropdown box).

So, in my db.py I have this:
from applications.appname.modules.countries import *
db.shipping_info.countries.widget = countries_widget

and in countries.py

from gluon.html import *
COUNTRIES=['United States', 'Afghanistan', ...]
def countries_widget(field, value):
return SELECT(COUNTRIES, _id=0)

and I get this error:
File "/home/darksun4/Sources/web2py/gluon/sqlhtml.py", line 595, in
__init__
inp = field.widget(field, default)
  File "/home/darksun4/Sources/web2py/applications/myapp/modules/
countries.py", line 4, in countries_widget
AttributeError: 'list' object has no attribute 'options'

If I place my widget code in db.py, everything works ok.

Also, what do you think about a db field, countries? Should I commit
something like that?

[web2py:32375] how to import html helpers inside a module?

[Jon Romero]

I have created a module (inside my application/modules) and I use
SELECT.
I tried importing gluon.tools but no go. All I get is this error:

NameError: global name 'SELECT' is not defined

[web2py:32373] A simple patch to provide upload progress

[AndCycle]

after read over this "thread [web2py:23034] Upload progress"
http://www.mail-archive.com/web2py@googlegroups.com/msg13111.html

I have looks around how other web framework done this,

in pylons's way, this require a WSGI middleware and URLmap,
unfortunately URLmap is impossible for web2py,
and wrap middleware like "gp.fileupload" or insert filer in cherrypy
also require lot's of hack,

in django's way, it hooks handler at input chain, which web2py doesn't
have,
but it just store the upload progress in cache, which is possible for
web2py,
so I made the patch to proof this works

I just made a proof of concept to provide upload progress,

part of code and idea taken from django snippets with some
modification
http://www.djangosnippets.org/snippets/678

 copystream(request.env.wsgi_input, request.body,
int(request.env.content_length))
 else:


maybe just wrap wsgi_input will make it pretty,

next is how to use it,

at controller, just require a function to respond json

def post():
#I need a from, give me give me
return dict(form=crud.create(db.foo_table))

@service.jsonrpc
def progress_report_by_id():
cache_key = 'X-Progress-ID:'+request.get_vars['X-Progress-ID']
return dict(
length=cache.ram(cache_key+':length', lambda: 0, None),
uploaded=cache.ram(cache_key+':uploaded', lambda: 0,
None),
)



at view you can do whatever you want,
this one is post.html for post function up there,

or just take javascript snippet part,

watch out "var progress_url",
you have to modify this to match your app/controller/function
somewhere

{{extend 'layout.html'}}

// Generate 32 char random uuid
function gen_uuid() {
var uuid = ""
for (var i=0; i < 32; i++) {
uuid += Math.floor(Math.random() * 16).toString(16);
}
return uuid
}

// Add upload progress for multipart forms.
$(function() {
$('form[enctype=multipart/form-data]').submit(function(){
// Prevent multiple submits
if ($.data(this, 'submitted')) return false;

var freq = 1000; // freqency of update in ms
var uuid = gen_uuid(); // id for this upload so we can fetch
progress info.
var progress_url = /poc/default/
progress_report_by

Looks like the problem is already addressed 3 weeks ago. But I did not

[web2py:32371] Internal Error in Administrative Interface

[Sujan Shakya]

I just checked out the web2py source from code.google.com.
Then I ran 'python web2py.py -a mypassword'
Then I visited http://127.0.0.1:8000/. This shows the welcome page.
But when I clicked on 'click here for the administrative interface'
link, I got 'Internal Error Ticket Issued' page. Clicking on the
ticket link opened another 'Internal Error' page.

Am I missing something ?

Thanks
