[web2py] Re: Need a little help with DAL
Are you using SQLite? Did you initially forget to define workers as an
integer field, enter some data, and then convert it to an integer field?
What happens if you start with a fresh db?

[web2py] CSRF consideration for running web2py with pure JS interface
Hi, We are creating our frontend using angular.js and the API layer is in web2py. The web2py documentation says - web2py prevents CSRF as well as accidental double submission of forms by assigning a one-time random token to each form. So how will that work in the instance of a pure JS frontend ? Will I need to implement something on the client side to enable it ? The initial request will go to the web2py app, which will send back the index.html, which will contain the js script as an include. This will load the js interface during the initial request. After this all calls will be ajax calls to the server, to return back JSON. Also I will be using the web2py authentication/authorization for securing the API. So would I be breaking any web2py compatibly in this regard or with any other security concerns ? Thanks, Murtaza --
[web2py] Re: A Web2py CMS like Joomla ?
On Wed, 13 Jun 2012 02:23:35 -0700 (PDT) Andrew awillima...@gmail.com wrote: I have started doing some trials with both instantpress and movuca, and I would have to say that it is not a question of which is better, each has a different focus and I've enjoyed using both (I'm still learning and still have heaps of questions though). I've decided to use (wx)python instead of D for our multi-platform project, so being already in Python-world it really makes sense to forget about PHP and use Python framework. Here we prefer full-stack one and between Django an Web2py, the latter wins in all the aspects except the number of ready apps...and here we think about blog/CMS ones. In Django there is Django-CMS, FeinCMS, Mezzanine...(there are more, but just picked 1st three from the below mentioned URL)... having blog engines and/or ecommerce packages nicely integrating with them. There is another aspect of the game: Django-CMS has (according to http://www.djangopackages.com/grids/g/cms/) 1654 repo watchers and 525 repo forks, FeinCMS (384/110) and Mezzanine (662/176). All of them are actively developed, there are submitted tickets which are commented by the devs and we can say there are communities developed around the projects. Otoh, situation with the two web2py CMS-es (there is also w2cms but not with much activity) is the following: 1) InstantPress: 18 followers, 0 forks, last commit 5 months ago, 5 (new) issues and not a *single* comment from the developer 2) Movuca CMS: 80 watchers, 14 forks, active development, 9 issues and *every* issue is commented by the main developer. I cannot judge the quality of the code itself, but it is pretty obvious which project build community around it. It's clear that web2py is simply too young and/or small to compare in numbers of apps within the Django community, but I'm sure it would be possible to focus on one CMS platform which is (more) focused on end-users (as it was already expressed in this thread) and make it actively developed, maintained sufficient flexible in order that all sites developed by it would not look as WP with Kubrick theme. Is there any interest for it? Personally, InstantPress looks more appealing to me as 'general' CMS/blog app in comparison with Movuca which seems to be more focused towards social networking, but I simply do not feel confident to invest time in learning the former. It could be that there is simply no interest within web2py community to build such thing, but the list referenced in wikipedia article ( http://en.wikipedia.org/wiki/Web2py): quote Applications built on Web2py Movuca CMS and Social Network Engine. Instant Press Blog platform. Ourway Social networking site. NoobMusic A rock music website. LinkFindr Network diagnostic tool.

Re: [web2py] Re: Making a field non-editable, but writable using SQLFORM
I understand the proposed procedure is as follows: 1. change db table field to writable 2. make the form as needed 3. change back db table field to not writable Suppose there are two concurrent users now, A and B, and they execute the above procedure. The concurrent scheduling is done by the server; one possible sequence is: A 1, B 1, B 2, B 3, problem occurs A 2, A 3. At the point of problem occurs, the db field is not writable and so the form will not be correct. On Tue, Jul 17, 2012 at 12:46 PM, Anthony abasta...@gmail.com wrote: Can you elaborate?

[web2py] Change in behaviour of cache
I have some code that works as follows
@cache('key', 60, cache_model=cache.ram)
@cache('key', 60, cache_model=cache.disk)
def f()
do stuff
return dict()
I do the dual cache thing since the ram cache is not shared between
processes that get spawned by Apache.
The recent changes to gluon/cache.py involving
particularly
File C:\src\web2py\gluon\cache.py, line 477, in tmp
action.__name___ = func.__name__
AttributeError: 'CacheAction' object has no attribute '__name__'
causes this to fail since the first @cache is a cache of a CacheAction
which by this stage does not yet have a __name__
I've added a __name__ = 'dummy' to the CacheAction __init__ but that feels
like a bad solution.
So
Suggestions?

I had to to do something similar a couple of years ago (between several waste water plants and the control center) and ended using a similar approach to what nick name said: - In the control center I used mysql - In the waste water plants I used a sqlite database per day (initializating the database every day at 00:00 and backing up the previous file in another directory) - Every record in the plants had a datetime stamp - The plants just send the sqlite files gzipped (and splitted in small bits because my connection was really bad) and the control center just received the bits, joined them, unziped the sqlite files and import their data into mysql using the plant-datetime as key to avoid duplicated items.

[web2py] Adding cancel button - form submission
Hello,
I have added a CANCEL button to my SQLFORM.
Form submission prevents the correct working of it.
I have tried to avoid form submission with this code :
def new_guest_contact():
form = SQLFORM.factory(...)
form[0][-1][1].append(TAG.BUTTON('Cancel',_onclick='ajax(%s,[],:eval);return
false' %URL(r=request,f='new_contact')))
if form.process().accepted:
...
redirect(URL(r=request,f='new_contact_part'))
elif form.errors:
response.flash = 'form has errors'
else:
response.flash = 'Create new guest'
return dict(form=form)
If I click the cancel button now, nothing happens anymore.
Any help is welcome.
Thanks

[web2py] Re: TAKE 2: Web2py + (jython / modjy) + Tomcat 6
I know this thread is a little old, but I really agree getting web2py going on a servlet container would be awesome. I followed Andrew's excellent example from the previous post, BUT i worked around the root url redirect issue by simply renaming the web2py folder to 'ROOT' (which, by convention, Tomcat will then serve from '/') Like this: Tomcat_HOME |__webapps |__ROOT | |__WEB-INF Anyway, I think I got closer than Andrew's attempt because (yay?) I got a real web2py ticket error. The contents of the web2pyticket was: (dp1 S'code' p2 S'' p3 sS'output' p4 S'' p5 sS'snapshot' p6 (dp7 sS'layer' p8 S'Framework' p9 sS'traceback' p10 S'Traceback (most recent call last):\n File C:\\Users\\duncanjm\\Documents\\various\\tomcat\\tomcat7\\webapps\\ROOT\\WEB-INF\\lib-python\\gluon\\main.py, line 475, in wsgibase\nsession.connect(request, response)\n File C:\\Users\\duncanjm\\Documents\\various\\tomcat\\tomcat7\\webapps\\ROOT\\WEB-INF\\lib-python\\gluon\\main.py, line 475, in wsgibase\nsession.connect(request, response)\n File C:\\Users\\duncanjm\\Documents\\various\\tomcat\\tomcat7\\webapps\\ROOT\\WEB-INF\\lib-python\\gluon\\globals.py, line 507, in connect\nresponse.cookies[response.session_id_name] = response.session_id\n File C:\\jython2.5.2\\Lib\\Cookie.py, line 579, in __setitem__\nself.__set(key, rval, cval)\n File C:\\jython2.5.2\\Lib\\Cookie.py, line 572, in _BaseCookie__set\n M.set(key, real_value, coded_value)\n File C:\\jython2.5.2\\Lib\\Cookie.py, line 450, in set\nif != translate(key, idmap, LegalChars):\n File C:\\jython2.5.2\\Lib\\string.py, line 491, in translate\nreturn s.translate(table, deletions)\nTypeError: translate() takes 2 arguments (2 given)\n' p11 s.

It will bring you back to the precedent page, in my use case, I direct the
user on a crud.read page where the user can edit the record (crud.update).
Then if don't want make change anymore there is a cancel hyperlink that
bring back the user on the crud.read page.

Re: [web2py] Re: [web2py-dev] Asyncronous Application Sync
I would set a Dropbox shared folder on both machines (there is a server dropbox.py for linux) So create a script which copies the .sqlite in to Dropbox folder. On city machine a scheduled task read records on sqlite and import new records directly to mysql. You are going to need a 'signal' field on every record. I am using 'N' for new, 'U' for updated, 'D' to deactivate. In this scenario it is not a good idea to delete any data, so use the is_active bool to change the status for deactivated. In the other side you can have the city machine exporting on to the sqlite database the records that should go to the forest. Also, you need to set a sqlite-status table, or file to be readed on both sides before any transaction occurs. (to avoid race condition) The better solution would be a mysql master-slave structure. But if yoi have connection issues you can go with a home made queue. http://zerp.ly/rochacbruno Em 17/07/2012 08:49, José Luis Redrejo Rodríguez jredr...@debian.org escreveu: I had to to do something similar a couple of years ago (between several waste water plants and the control center) and ended using a similar approach to what nick name said: - In the control center I used mysql - In the waste water plants I used a sqlite database per day (initializating the database every day at 00:00 and backing up the previous file in another directory) - Every record in the plants had a datetime stamp - The plants just send the sqlite files gzipped (and splitted in small bits because my connection was really bad) and the control center just received the bits, joined them, unziped the sqlite files and import their data into mysql using the plant-datetime as key to avoid duplicated items.

Re: [web2py] Re: Recommendations on model file size (database tables)
Yeah that is what I was just sharing. My site was slow I have over 200 models now. My setup is: models/controller/action/db.py - In here it includes a function define_tables(db, tables = [], migrate=False, fake_migrate=False) The define_tables is a function that I put somewhere else out side of models and it is if statements checking: First if the table in tables already exists in db.tables if so skip the table generation. Other wise checks if I have a definitions for that table if I do define it. This has helped increase the speed of the site a lot. I am still doing some other major optimizations like just hitting the front page of the site does 53 requests to the server I want to drop that at least in half.

The fact that you don't have sudo installed tells me you might have chosen the wrong instance type. I'd say stop that instance (unless you have critical data or code on that box) and start a new micro 64-bit micro instance with 64-bit Ubuntu. Once you are in the instance via ssh, run: sudo script_name_here.sh it should prompt you for your password, and then proceed to install.

[web2py] Re: CSRF consideration for running web2py with pure JS interface
CRSF only works if you use SQLFORM. Do you? Then it depends on how to use
it. The workflow is the following
1) visit the page
{{=SQLFORM().process()}} generate the html for and injects some hidden
fields in it
2) you submit the form
{{=SQLFORM().process()}} check the hidden fields and accepts of rejects
the submission
If you use SQLFORM (even if via ajax) you must make both calls, retrieve
and display the hidden fields.

Hi,
We are creating our frontend using angular.js and the API layer is in
web2py. The web2py documentation says -
web2py prevents CSRF as well as accidental double submission of forms by
assigning a one-time random token to each form.
So how will that work in the instance of a pure JS frontend ? Will I need
to implement something on the client side to enable it ?
The initial request will go to the web2py app, which will send back the
index.html, which will contain the js script as an include. This will load
the js interface during the initial request. After this all calls will be
ajax calls to the server, to return back JSON.
Also I will be using the web2py authentication/authorization for securing
the API. So would I be breaking any web2py compatibly in this regard or
with any other security concerns ?

Current features: - one-time-only tasks - recurring tasks - possibility to schedule functions at a given time - possibility to schedule recurring tasks with a stop_time - can operate distributed among machines, given a database reachable for all workers - group_names to divide tasks among different workers - group_names can also influence the percentage of assigned tasks to similar workers - simple integration using modules for embedded tasks (i.e. you can use functions defined in modules directly in your app or have them processed in background) - configurable heartbeat to reduce latency: with sane defaults and not t many tasks queued normally a queued task doesn't exceed 5 seconds execution times - option to start it, process all available tasks and then die automatically - integrated tracebacks - monitorable as state is saved on the db - integrated app environment if started as web2py.py -K - stop processes immediately (set them to KILL) - stop processes gracefully (set them to TERMINATE) - disable processes (set them to DISABLED) - functions that doesn't return results do not generate a scheduler_run entry - added a discard_results parameter that doesn't store results no matter what - added a uuid record to tasks to simplify checkings of unique tasks - task_name is not required anymore - you can skip passing the function to the scheduler istantiation: functions can be dinamically retrieved in the app's environment So, your mission is: - test the scheduler with the app and familiarize with it Secondary mission is: - report any bug you find here or on github ( https://github.com/niphlod/w2p_scheduler_tests/issues) - propose new examples to be embedded in the app, or correct the current docs (English is not my mother tongue) Once approved, docs will be probably embedded in the book ( http://web2py.com/book) Feel free to propose features you'd like to see in the scheduler, I have some time to spend implementing it. --

idloc = request.post_vars.id
id,column = idloc.split('.')
value = request.post_vars.value
db(db.WSProb.id == id).update(**{column:value})
return value
It seems jeditable submits its values through request.post_vars instead of
using request.args
I also modified the update clause so it would work with passing a column
name in as text.
I am using the source 1.7.1 version of jeditable from the

With minimal testing this seemed to allow you to update the numbers and

Re: [web2py] Re: Recommendations on model file size (database tables)
Just think about it loading a page that queries from one table, and models that define 200 tables. For that single query 200 tables must be define with the default web2py setup. This isn't rocket science to know it will be wasting a lot of resources and slow down performance every extra function call will cause performance problems on a high traffic website. Lets not forget with every model definition it will use more memory. Another performance problem is translations for sites with a lot of translations strings as the entire dictionary must be loaded into memory. This part I am still thinking whether having a different file per action would be worth it to improve speed.

$(this).children(:selected).attr(value);$(this).trigger($(this).attr(id)

return dict(..., conditional_field_trigger_selected_event_js

# In view
{{if request.args(0)=='SOMETHING':}}
script type=text/javascript
var conditional_field_trigger_selected_event_js =
{{=XML(conditional_field_trigger_selected_event_js)}}
eval(conditional_field_trigger_selected_event_js);
/script
{{pass}}
But, still curious to know if there is security issue with javascript
eval(); the way I use it.
The purpose of this is to use lazy_option_widget plugin (
http://dev.s-cubism.com/plugin_lazy_options_widget) without having to use
suggest widget that is a dependency of lazy_option_widget... Since
lazy_option_widget only need selected event to be trigger on by suggest
widget, giving it trigger event from a default web2py dropbox allow to
eliminate the dependency.
In the future I would implement a custom dropbox widget that support
trigger selected event. Thought it could be nice to have a option in the
default web2py dropbox widget to activate and deactivate as needed selected
trigger event, but don't know if it a good idea.
Thanks to answer.

(I suppose they also apply to other Auth functions in general):
1. In a controller, if I do:
def register():
return dict(form=auth.register())
with the following settings in a model:
auth.settings.registration_requires_verification = True
auth.settings.register_next = URL (...)
Everything works as expected, i.e. the verification email is sent after
the registration form is processed, and the user gets re-directed to a
different page. However, as soon as I do sth like:
def register():
form = auth.register()
if form.process().accepted:
session.flash = 'Registration form processed, please check your
email'
elif form.errors:
response.flash = 'Registration form contains error(s)'
else:
response.flash = 'Please fill in the registration form'
return dict(form=form)
*Both verification email and re-direction stop working even though the
form processed successfully* (a record is inserted, the form clears
itself, and a flash message 'Success!' appears). I wonder what causes this
breakdown? I am using the trunk version of web2py.
2. How much customization can we do with the form returned by
auth.register()? I know we can add add fields to it (a few different ways),
but there are many other things one may want to adjust. For example, I am
able to do sth like:
form.element(_type='submit')['_class'] = '...'
to change the class of its elements. How do we change the class for the
whole form? How do we change the label for each field? How do we adjust the
position of each field? How do we position the whole form on the page? etc.
Thanks in advance!

Re: [web2py] Re: Recommendations on model file size (database tables)

The conditional models are good, but the problem is the fact that they are not reusable, when you need the same table on multiple controllers, or you have to define it globally, or you have to repeat the definition on every sub model. I think having a module with functions or classes to define the tables are better, and qhen you have this, you dont need to use submodels, because you can run each desired function/class direclty on the controller.

But, still curious to know if there is security issue with javascript
eval(); the way I use it.
The purpose of this is to use lazy_option_widget plugin (
http://dev.s-cubism.com/plugin_lazy_options_widget) without having to use
suggest widget that is a dependency of lazy_option_widget... Since
lazy_option_widget only need selected event to be trigger on by suggest
widget, giving it trigger event from a default web2py dropbox allow to
eliminate the dependency.
In the future I would implement a custom dropbox widget that support
trigger selected event. Thought it could be nice to have a option in the
default web2py dropbox widget to activate and deactivate as needed selected
trigger event, but don't know if it a good idea.
Thanks to answer.

Sorry, only percentage is supported.
Pt and Em and any other unit is not supported.
I'll try to add better error messages and documentation, sorry for the issue.
I find this remarkable; this ordinary HTML; web2py encourages the use of
HTML helpers. web2py is easy to use, requires few dependencies, etc. etc.
But what a fight to create a simple table-based PDF! :-( And I'm still
experimenting in the layout stage. My final report will be much larger and
include nested tables (that are already rendering fine in HTML, but not in
pyfpdf / html2pdf).
Sorry, but definitively your report is out of scope of html2pdf /
pyfpdf right now.
Please remember, the current implementation is a basic HTML parser to
do *basic* reports.
Nested tables are not supported and I don't think they will in the near future.
If I could get some funding maybe I could spend more time enhancing this.
Should I bite the bullet and install Reportlab? It'll be harder to get
started, more complicated to install maintain (this will have to go on
multiple machines). The idea of a simple web2py project was very attractive
for these reasons.
AFAIK Reportlab doesn't even have a html2pdf conversor.
If you switch to reportlab, you will have to code your report using PlatyPlus.
You should consider they commercial licence that includes paid support
for this kind of issues.
As you said, the html2pdf recipe is a simple web2py project
Maybe you have to go with third-party tools like Pisa (xhtml2pdf) or
use built-in pdf conversion of chrome-browser, or pdf printers.

Just curious:
There is a special reason to not simply return the needed dicts?

[web2py] Import CSV in appadmin to update database
I would like to know how I would add an import csv (from excel) option to appadmin that would update multiple database tables (one of them a relational/intermediate table). For example, the CSV file would look like this (in excel) ID | posttitle |category | 1 | title1 | cat1, cat2| 2 | title2 | cat2, cat3| 3 | title3 | cat1, cat3| Uploading this would update table 1 with the ID and posttitle, and also the intermediate/relational table with the relationship between posttitle and category (as described here: http://web2py.com/books/default/chapter/29/6#Many-to-many). I'm new to web2py and couldn't find anything in the book, also the questions previously asked already had a good grasp of what to do add a CSV upload feature. I'd appreciate any help as I'm not really sure where to start with this, thanks! --
[web2py] Re: Jeditable and SQLTables
Thanks Brent,
Appreciate that, but the main issue is that the controller does not called
from jQuery. i.e. from this line
jQuery('.EDit').editable({{=URL('update')}},{
There no post vars.
(have also used a brute force updates to confirm that it doesn't fire)
If we can only find out why.
(thinking is a fundamental concept that I'm missing)
Will give that another go today, but would be grateful for any hints.

the update() function in the controller:

idloc = request.post_vars.id
id,column = idloc.split('.')
value = request.post_vars.value
db(db.WSProb.id == id).update(**{column:value})
return value
It seems jeditable submits its values through request.post_vars instead of
using request.args
I also modified the update clause so it would work with passing a column
name in as text.
I am using the source 1.7.1 version of jeditable from the
sitehttp://www.appelsiini.net/projects/jeditable.
With minimal testing this seemed to allow you to update the numbers and
display the updated value.

Sorry for the delay - first chance to delve into this again. Still no

Do you have a quick example that works (just a cut and paste one would

[web2py] Re: CSRF consideration for running web2py with pure JS interface
I don't think there are any SQLFORMs. It's all custom Ajax calls. I'm guessing your JavaScript library (angular, in this case) needs to take care of it? Presumably you could still use SQLFORM to generate the _formkey value, send it to the client, and have the client send it back with the form submission. This doesn't require using web2py's default form serialization in the view. It's probably only worth doing it this way if you are using SQLFORM on the server side for processing. Anthony --
[web2py] Re: Foreign Key fields as null?
You should probably make it a reference field. By default, if you don't
specify any requires, you'll automatically get an IS_IN_DB validator as
well as a represent attribute that displays whatever is specifying by the
format attribute of the referenced table. However, if you specify your
own validator(s), then you don't get any default represent -- so just add
your own explicit represent:
db.define_table('dog',
Field http://127.0.0.1:8000/examples/global/vars/Field('name'),
Field http://127.0.0.1:8000/examples/global/vars/Field('owner', db.
person,
requires=IS_EMPTY_ORhttp://127.0.0.1:8000/examples/global/vars/IS_EMPTY_OR
(IS_IN_DB http://127.0.0.1:8000/examples/global/vars/IS_IN_DB(db,
'person.id', '%(name)')),
represent=lambda id, row: db.person(id).name),
format = '%(name)s')

When I have the above code, a foreign key will be stored in the database, but
all views of that key will be rendered as the numerical value of the foreign
key, and not the name. In the table definition, if I just have *db.person*
instead of requires = *IS_EMPTY_OR*(*IS_IN_DB*(db,db.person)), It requires
the field.
Are there any workarounds?

Thanks, Massimo, I'm happy to say that I now have a *working*** web2py install in Tomcat*!

Woot! :) For clarity: I commented out lines 450/451 in the Jython Cookie.py file: #if != translate(key, idmap, LegalChars): #raise CookieError(Illegal key value: %s % key) *So the remaining bits of work I need to do is check up on the details of making a JDBC connection to sqlite instead of driver-based.

It is possible. Yet there is some overhead because SQLFROM is built on top of helpers. It will create a representation of the form even if it unused. It may work to create a SQLFORM light that only does what you need. It can be done in a few lines of code.

Re: [web2py] Re: CSRF consideration for running web2py with pure JS interface
Yes it will be only ajax calls and I will not be using SQLFORM. I am presuming this is the mechanism you use for preventing CSRF attacks - 1) Generate a unique value for every form that is sent to clientside. 2) Assign this value to _formkey, and also store it in the session. 3) When the user submits the form back compare the value in the _formkey and the session. 4) If the value matches then its a valid request, otherwise its an attack. If you are using the above mechanism - 1) How do you know which formkey to compare to which key in the session. As you have generated multiple form keys and stored them in session, one for each form. I was thinking of this scheme for CSRF protection - 1) Generate a CSRF protection token and set it on client side during the first request. 2) On every subsequent ajax call the client will grab the token and post it with the data. (client side double submit) 3) The server will compare the returned cookie value with the POST request, to verify if it is a valid request.

I am presuming this is the mechanism you use for preventing CSRF attacks - 1) Generate a unique value for every form that is sent to clientside. 2) Assign this value to _formkey, and also store it in the session. Yes, but _formkey is stored along with the _formname, so it is associated with a particular form (which answers your question below). 3) When the user submits the form back compare the value in the _formkey and the session. 4) If the value matches then its a valid request, otherwise its an attack. If you are using the above mechanism - 1) How do you know which formkey to compare to which key in the session. As you have generated multiple form keys and stored them in session, one for each form. As noted above, a _formkey goes with a particular _formname. That means if multiple forms with the same name have been loaded in the browser (e.g., in separate tabs, or even on the same page), only the last form generated will work (because its _formkey will have overwritten the _formkey of any previously generated form with the same name). We've discussed allowing multiple formkeys for the same formname, so if a user opens a second tab and then goes back to the first tab to submit a form, the submission will work rather than failing. Note, the _formkey mechanism is intended to prevent double form submission in addition to CSRF (though you can protect against double submission on the client via JS as well). I was thinking of this scheme for CSRF protection - 1) Generate a CSRF protection token and set it on client side during the first request. 2) On every subsequent ajax call the client will grab the token and post it with the data. (client side double submit) 3) The server will compare the returned cookie value with the POST request, to verify if it is a valid request. Sounds reasonable. Anthony --
