[web2py] Re: new plugin - web2py Form Wizard - PowerFormWizard

[niknok]

In the validation example,  I entered a single character in the Bio
and was allowed to proceed to the next field despite the
db.person.bio.requires = IS_LENGTH(minsize=5, maxsize=200). You  made
a note about "Client side validation is not supposed to validate
everything!", is this included in that exception?

A few suggestions:
* How about using "description" or "details" instead of the "legend"
keyword at it seems to be more appropriate for said function.

• As default behavior, instead of the default "X" errorImage beside
the step title, how about using an exclamation point icon to indicate
that this step needs attention and then in the specific field with an
error use the "X" icon instead.


The other day you answered my query re modal windows with a reference
to easyframework.com + web2py.

I pray that you have plans of adding that feature to your
PowerFormWizard Plugin (or perhaps turning this into a "PowerForms"
plugin to truly enable feature-full forms in Web2py?

Cheers and many thanks for your many contributions to the web2py
community.

Re: [web2py] Invalid view in 1.97.1

[Bruno Rocha]

By default, generic views will be disabled, it is a security issue,

but you can active at your own risk.

in any model file include


response.generic_patterns = ['*']


And it will enable all generic views.


Massimo needs to update the example app to get this working again.

[web2py] Invalid view in 1.97.1

[Gary Herron]

I'm getting an occasional "invalid view" error since I upgraded to 
1.97.1.  Since  it was on a web site I was experimenting/learning with, 
I thought it might be my problem, but I no longer think so.


On controllers with no corresponding view, there is supposed to be a 
generic view which handles the formating of the page -- but that seems 
to have gotten lost in 1.97.1 -- in at least some cases.


Here is a page right out of web2py.com which (I'm pretty sure) used to 
work, but now exhibits this error:

Visit
http://web2py.com/examples/simple_examples/hello6
and get
invalid view (simple_examples/hello6.html)

Any clues, fixes, explanations would be welcome.

Thanks,

Re: [web2py] SECOND TRY TO GET IT ON THE LIST how redirect without propagate the .load extension?

[Anthony]

OK, I forgot the underscore before 'action' (I also forgot to include 
request.args in the form action URL) -- I think this should do it:
 
form.update(_class='no_trap', 
_action=URL('default','create_fvte.html',args=request.args))
 
 
Note, adding the .html extension to create_fvte above ensures that when the 
form is submitted back to this function, the extension will be .html, which 
is the extension that will be passed to the redirects.
 
Also, you should remove the following from create_fvte:
 
else:
response.flash = T('please fill out the form')
 
 
The problem with that is that when you redirect to the /creation URL, it 
reloads your components, and the response.flash from the components 
overrides the session.flash that was passed to the /creation page. Instead, 
put the following in the creation() function:
 
if not request.args:
response.flash = T('please fill out the form')
 
 
That will flash 'please fill out the form' when the /creation page is loaded 
without any arguments, but not otherwise.
 
With those small changes, I believe it all works as you want now.

[web2py] Re: Disabling Input Validation/Output Incoding

[Anthony]

Also, I think all the escaping is done by web2py's template engine, so you 
could avoid the escaping by skipping use of templates. To do that, have your 
controller action return a string of (unsafe) HTML instead of a dictionary 
of values to pass to a view -- the HTML string will be returned as the 
response to the browser without any sanitizing.

Anything you put inside XML() will not be escaped (unless you set its

Re: [web2py] SECOND TRY TO GET IT ON THE LIST how redirect without propagate the .load extension?

[Richard Vézina]

I don't find it's that hard... I think it should be as simple to perform
redirection with the components than it is with the standard forms... But
there is a other level of complexity here with the Tabs plugin and it
becomes tricky to test it, I become mix up sometime  ;-)

[pbreit]

I switched it to this which saves the data and shows the empty form again:

if table == 'ref_fnaregistry':
redirect(URL('default', 'create_fvte.load', 
args='ref_fnaregistry'))

I would very strongly advise simplifying your app. This is far more 
complicated than it needs to be and I suspect you will continue to run into 
a lot of hard to solve problems like this.

It's not your problem, but it's 'http_referer'; it got misspelled somewhere 
back in the mists of Internet time.

It's an absolute URL, so URL() won't do anything useful with it. You'll need 
something more like _href=request.env.http_referer.

Alternatively, you can parse it and pull out the bits that you need to pass to 
URL() (assuming that the referring page is in your app).

Generally speaking, I think you're better off tracking the referral chain 
internally, rather than relying on http_referer.

[web2py] Disabling Input Validation/Output Incoding

[David Schoenheit]

Hi,

I am using web2py to write an intentionally vulnerable web app in
order to demonstrate basic cross site request forgery and cross site
scripting attacks for educational purposes. I'm running into some
problems where web2py is automatically html encoding my output and
preventing the intended attacks from working. Is there a way to

So far I have tried the following in the template file:
{{=A('Back', _href=URL(request.env.http_referrer))}}

Trying to supply the http_referrer through a dict does not work either.

I'm certain I must be overlooking something...

[web2py] Calculate field value only once

[DanB]

Sorry for the repeat question, but I'm trying to figure out how to
create a calculated field that only populates when the record is
originally created (i.e. calculate on create, but do not recalculate
on update). Same question as here:

http://groups.google.com/group/web2py/browse_thread/thread/1b29979f2c63f225/085221abcb401ff0?lnk=gst&q=calculated+field#085221abcb401ff0

Is there a way to do this "out of the box"? Or is it just better to
write a function that checks for an existing value before running and
returning the calculation.

Thanks in advance!

P.S. *Amazing* framework! Just got started and I'm loving every new

[web2py] How to prevent eclipse from formatting sections of python embedded in your .html files.

[Dave]

This is my first post here. Hopefully I'm posting where I should and
that this hasn't been covered already. I am hoping that someone else
has a better solution.

Using eclipse to edit .html files that have embedded python can be a
little frustrating if you (like me) have a habit of pressing ctrl+shift
+f to ask eclipse to format the file for you. Sections of embedded
python code that look like this:
{{...}}
{{...}}
{{...}}
{{...}}

will end up looking like this:
{{...}}{{...}}{{...}}{{...}}

One way to prevent eclipse from playing with the code is by  doing
this:

{{=XML("<" "/pre>")}}
{{...}}
{{...}}
{{...}}
{{...}}
{{=XML("<" "pre>")}}


Does anyone know of a better way to achieve this result?

Thanks!

Re: [web2py] SECOND TRY TO GET IT ON THE LIST how redirect without propagate the .load extension?

Sorry, the **dict() isn't really needed -- you can just do:
 
form.element('form').update(_class='no_trap', 
action=URL('default','create_fvte'))
 
 
Actually, in the URL() call above, you might be better off doing 
'create_fvte.html' to ensure it doesn't use the .load extension, which would 
then propagate to the redirect (unless you explicitly specify .hmtl in the 
redirect).

Yes, that's the same issue as has been discussed before regarding generic 
views and is not unique to that slice. Due to a potential security issue, 
generic views are now disabled by default and can be enabled by specifying 
response.generic_patterns. The 'welcome' app includes a statement in db.py 
that enables all generic views, but only for local requests.
 
Also, response.generic_patterns is not getting passed to non-ajax 
components, so generic views aren't working at all for non-ajax components, 
unless you explicitly set response.view='generic.[extension]'. This problem 
will be fixed soon.

Try this:

The _class='no_trap' should turn off the trapping of the form, and the

gets submitted back to the create_fvte function rather than the parent page 
(i.e., the index function). Because the form will not be submitted via ajax, 
the redirect should work as usual and reload the entire page.

[web2py] Re: web2py and async monkey patching

[graeme]

I tested with Eventlet and Gunicorn with Eventlet workers, and both
can be made to work. I loaded the page in two web browsers
concurrently rather than calling from the console, but I think I can
assume that this is immaterial?

Eventlet monkey patching only works if it is called before any imports
of the patched libraries happen, so it cannot just be dropped into
anyserver.py as is, but it is trivial to write a script to use it.

For Gunicorn, there is a bug in the gunicorn method (incidentally, it
is also called gnuicorn) in anyserver.py (too many arguments given to
Arbiter init) which stops it working at all. I could not find the docs
I needed to fix it, so I wrote this in a file called
web2py_eventlet.py:

from eventlet import monkey_patch
monkey_patch(all=True)
import gluon.main
app = gluon.main.wsgibase

and ran gunicorn with

gunicorn -w 1 -k eventlet web2py_eventlet:app

it also works fine.

It is possible to monkey patch psycopg to be always async as well, but
I do not think this will work with web2py as the connection.commit()
and connection.rollback() methods will not work as expected.

That brings me to another problem. I wonder if it is worth bothering
with an async web server, given that the database is going to require
a thread or process per concurrent request anyway. Is there anyway
around that? Does a request need to tie up a database connection while
waiting for something else to happen?

ajax_trap has always been ignored when ajax=True -- in other words, when 
ajax=True, the component will always trap forms submitted. Actually, it 
looks like you can override that by adding a 'no_trap' class to your form. 
But in that case, the form will get submitted to the parent page controller 
function, not to the original controller function that generated the form, 
and you probably don't want that. You may be able to explicitly set the form 
action to post to the component action, and along with setting 
class='no_trap', that might solve your problem.

Re: [web2py] SECOND TRY TO GET IT ON THE LIST how redirect without propagate the .load extension?

[Richard Vézina]

ajax_trap is ignored and assumed to be True if ajax=True.

Earlier tests with orther versions had a different behavior and I conceived
ajax_trap=False as a kind of two purposes option. On one hand when
ajax=False it could be use to keep the next form into ajax... And when
ajax=True it works as a mean to stop trapping the next form into ajax.

I would like to have the validator trapped but not the next form... It was
working like that before but not anymore...

Re: [web2py] SECOND TRY TO GET IT ON THE LIST how redirect without propagate the .load extension?

[Richard Vézina]

I don't understand that from the book :

ajax_trap=True means that any form submission in the DIV must be captured
and submitted via Ajax, and the response must be rendered inside the DIV.
ajax_trap=False indicates that forms must be submitted normally, thus
reloading the entire page. ajax_trap is ignored and assumed to be True if
ajax=True.

Let me explain a bit my problem :

I use jQuery UI Tabs with a component into a couples of tabs and I manage
those component with a unique function since the differents form-table
passed like this crud.create(request.args(0)...

So I redirect if form submit like this :

if form.accepts(request.vars, session):
session.flash = T('form accepted')
request.extension = None
if table == 'ref_fnaregistry':
#redirect(URL(request.application,c='default',f='index.html'))
redirect(URL(request.application,c='ref',
f='creation.html',args=1))
elif table == 'ref_vregistry':
redirect(URL(request.application,c='ref',
f='creation.html',args=2))
elif table == 'ref_tregistry':
redirect(URL(request.application,c='ref',
f='creation.html',args=3))


But the URL in the nav url box not change that let me think that the
redirection is trap into ajax... Then there is a other sign with the
calendar that show up but not return any date on clic...

If I redirect on :
redirect(URL(request.application,c='default',f='index.html')) I get the
whole site into my first tab...

ajax_trap isn't related to redirects -- it only applies when ajax=False -- 
in that case, when ajax_trap=True, it tells web2py to trap form submissions 
in the component and post them to the component's action rather than to the 
parent page's action

[web2py] Re: matplotlib image map using web2py

[G]

To follow up, if I were to go about this in a brute force manner, by
simply saving the dynamically generated figure to a randomly generated
file and then passing that file to an AREA MAP / IMG tag, where in the
web2py directory structure would be the recommended place to do so? I
suppose using the SQLLITE database might be a natural option. Any
opinions? Are there any examples of doing something like this? I
suppose it's vaguely similar to a photo album application, except the
photos are dynamically created and deleted after use.

Hello,

I have problem with propagation of load extension I think with redirect that

Calendar plugin not working correctly on redirected pages...

Here what I found about my problem :
http://groups.google.com/group/web2py/browse_thread/thread/67e2a28a2e8ec7d6?pli=1

I tried what Jonathan suggested in the threads : request.extension=None but
it seems that .load still propagate... First the url that I pass in my
redirect should appear in the navigation address bar. Second the validator
don't show up on a redirected form that fail...

Help please ;-)

Only web2py model, controller, and view files have access to the web2py 
globals -- in a module, you have to explicitly import web2py stuff. You 
could do:
 
from gluon import *   # to get all the web2py globals
 
or
 
from gluon.dal import DAL, Field  # for just the DAL stuff
 
 
If you're importing from outside web2py, make sure the web2py folder is in 
your sys.path. Or, since the DAL can be used independently of the web2py 
framework, you could just copy the /gluon/dal.py file to wherever you want 
to use it.

Yes, as of 1.96.1, you can use regular Python import statements to import 
from the app's /modules folder, and local_import is deprecated (and I think 
may not work if your modules import other modules).
 

>  And running a module in the controllers directory doesn't seem to give it

No, just putting a module in the controllers directory wouldn't give it 
access to the DAL or any web2py globals. When a request comes in, the 
particular controller requested is executed in an environment with all the 
web2py globals defined, but that wouldn't apply to a module dumped in the 
controllers folder.

If you're not creating an app that receives requests and just want to use 
the DAL as a module with your robot scripts, you can probably just pull out 
the dal.py file and use it as a standalone Python module, importing as 
usual.

[web2py] Use the ORM for a robot?

[Nick Arnett]

I'm just getting to know Web2Py after working with Django a fair bit.  I
have robots that gather data that I would like to insert using the Web2Py
ORM, but I can't quite figure out the right way to do that.  If I put the
bot scripts in the modules directory, I don't seem to have access to the
ORM.  When I run a module in the controllers directory, I can import from
the modules directory with a simple import even though the documentation
seems to say that I should use local_import... which doesn't work.  And
running a module in the controllers directory doesn't seem to give it access
to the ORM, either.

So... I'm lost and not finding the answer in the docs.  In Django, I would
just put the appropriate imports in the robot scripts, but I get that that's
not the Web2Py way!

Can anybody point me to an example of this sort of thing - inserting data
that isn't coming from a request - or give me an idea of the right way to
organize it into the Web2Py structure?

Thanks in advance.

Nick

This depends on which router you use. The parametric router will continue to 
handle the old (unshortened) URLs just fine.

[web2py] Re: new plugin - web2py Form Wizard - PowerFormWizard

[blackthorne]

yes! awesome!

just came to my mind having such a system for multiple forms/wizards
managed by the db. So you could easily add forms like that in your app
and manage them. Good for more complex apps like SAP.

Strange this did not work.


But Bruno's solution did.

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

Re: [web2py] routes and SEO question

[Bruno Rocha]

In default.py just create a function called default.

def default():
if request.args(0):
redirect(URL("default", request.args(0))

This will act as a proxy.

[web2py] Re: CAS

[Massimo Di Pierro]

Try use the latest web2py with

Auth(cas_provider='http://default/user/cas')

and it should be smart about passing over field values.
Ina ny case CAS can be customized a lot. Loot at the code examples in

gluon/contrib/login_methods/cas_auth.py

If you want to test specifically whether 'form' was returned in the dict of 
the controller action (as opposed to possibly being defined in a model

Not yet in plugin, but, That's all Java Script, so you can raise the method
by hand.

Is there a public JS method:

$.fn.stepy.step(2, '#powerformwizard');

and you can change the _id on form creation.

I will think about to include it in plugin.

[web2py] Re: conditions in HTML Helper TABLE

[Anthony]

Helpers are callable objects that take arguments, and you cannot use an if 
statement as an argument in Python. However, you can use a conditional 
expression, so the following should work:
 
*[TR(TD(row.DBQuery.ExampleName), _class='Test1' if row.DBQuery.Value==1 
else 'Test2') for row in query]
 
 
See 
http://docs.python.org/reference/expressions.html#conditional-expressions.

[web2py] Re: proven hosting sites for web2py

[blackthorne]

well, I have to disagree.
Not that I wouldn't think like with your experience. I just have to
say that I have a webfaction account with around 3-4 apps at the most
cheap plan which is really low and It's working very well. Until now,
I had a great experience with them, almost 2 years have passed. Now I
am more apprehensive by your negative comments, but still would
recommend webfaction.

[web2py] conditions in HTML Helper TABLE

[Christian Degenkolb]

Hi

is it possible to use conditions in HTMl Helpers like TABLE()?

for example I build a HTML table with

tablehelper = TABLE(
TR( TD(TD(B("Example"))),
*[ TR(  TD( row.DBQuery.ExampleName) ) for row in query]
)

now is it possible to do something like?
tablehelper = TABLE(
TR( TD(TD(B("Example"))),
*[ TR(  TD( row.DBQuery.ExampleName), if row.DBQuery.Value == 1:
_class='Test1' else: _class='Test2' ) for row in query]
)

I couldnt find anything in the manual regardding this problem.

[web2py] Localising decimal values in form fields

[tomtom5]

I'm currently diving into web2py and got a problem localising input/
output of Decimal/Double form fields according to the users (browsers)
locale. I understand the mechanism of internationalising messages with
T(..), but that doesn't seem to help me further. What I need is, that
for example a german user may input a decimal value as 123.456,78
while an american user will use 123 456.78 as input/output format. I
found methods to define the decimal separator char in the constructor
of the IS_DECIMAL_IN_RANGE validator, but this is very rudimentary and
will not be user-locale aware. Is there a way to solve the problem out
of the box or should I create new validators or widgets for such a
task?
Thanks for advise

[web2py] Re: Empty database default values?

[Ross Peoples]

The default, if not specified is always None (NULL). Some DBAs will argue 
for and against storing NULL values in a database, but I personally use 
NULLs simply because they allow more flexibility. For example, say you have 
a text field in one of your tables. This text field should be set by the 
user, even if the text is empty, the user should set it. This would be 
stored as '' (empty string) in the database. So now, if you wanted to go 
through the database to find records where this text field as never been 
set, all you have to do is search for None.

That may not be the best example, but you may find lots of cases where you 
can use None (NULL) to your advantage. A better example might be for a time 
clock. You have a start_date and end_date. If end_date is None, then you 
know that person hasn't clocked out yet.

It's all a matter of personal preference.
