[web2py] Re: reddit again
Agree. Web2py has achieved a good ever growing userbase momentum now. 2 years ago there were like 6 threads created/updated daily in this Google groups discussion, Currently, its like 4-5 times that number. We are not the same skinny new kid on the block anymore. There is no need to hijack other frameworks' threads. Guerrilla marketing tactics worked well but now we can move on with seduction, atracting users instead of 'stalking' them. Disclaimer: I am proud web2py fan since 2008.

[web2py] GSOC 2011 - BioChemical Reaction Network Visualization - web2py
Hi web2py coders, I am very happy to tell you that my group - Theoretical Biophysics at the HU-Berlin - got selected for a mentoring program for the GSOC2011 (http://code.google.com/soc/). We want to create an new layout algorithm for biochemical reaction networks, a visualization of the reaction network using SVG and SBGN and a web based (js) SVG editor for the reaction networks. One of the software tools that we would need is a communication layer that brings the graph visualization to the browser. Since we develop a lot of software in our group with the help of web2py it would be great if one of you would be interested in helping us to achieve our vision. The work will have to be done within two month during the summer and you would get payed a nice amount of money by google. You will find more information about our GSOC project here http://rumo.biologie.hu-berlin.de/gsoc/ (read especially Idea 3) If you are interested and you want to discuss ideas with us join http://groups.google.com/group/tbp-soc2011-stud Please be aware that if you want to join you should bring some coding skills. In addition to that please be aware that Idea 3 does not have the highest priority since it depends on other components (layout algorithm and SVG rendering) which some of you might also be interested in.
[web2py] Re: update db.table from custom form
Hi,
the input type button specifies a push button for use with client-side
scripting. The VALUE attribute gives the text label of the button. The
ONCLICK attribute is typically used to define the action taken when
the button is activated.
This means that your form has to use ONCLICK (or a similar event) to
create a call to the server from the client's browser.

[web2py] Re: Menu based on Boolean table fields.
Thanks for your reply. I had a look at the code, but I am afraid it
doesn't solve my problem. The functions are fields in a table and
depending on their value being true or false they should be rendered
as an a/a or h4/h4 element.
Given this code in a function:
session.id=auth.user.bedrijf_id
session.row=db(db.cardfunction.bedrijf_id==session.id).select(db.cardfunction.ALL)
session.card_menu=[
['Home',request.function=='index',URL(r=request,f='index')],
['Logo',request.function=='logo',URL(r=request,f='logo')],
...
['Keywords',request.function=='keywords',URL(r=request,f='keywords')]]
.. I am looking for a way to make use of the _name attribute, for this
is the same as the field name, something like:
ul
{{for _name,_active,_link in session.card_menu:}}
{{if session.row._name:}}
li
a {{if _active:}} class=active {{pass}}
href={{=_link}}{{=_name}}/a
/li
{{else:}}
li
h4 class=disabled{{=_name}}/h4
/li
{{pass}}
{{pass}}
/ul
The problem is that this: {{if session.row._name:}} results in a
KeyError '_name'
Is it possible to use _name to accomplish this?
Kind regards,
Annet.

[web2py] Re: reddit again
I have stated several times that Massimo should be very careful in advocating for Web2py. I'm still holding this opinion. But I won't elaborate on this. About the facebook clone. I do not see anything offensive about this video. I thought it's pretty good. But it can be improved. How? Well, Facebook, Reddit, etc. are quite trivial applications in terms of functionality and features. But Facebook doesn't work perfectly and Reddit fails once every other day. Why? The answer is Scalability These applications are hard to build to withstand a tremendously large user base. Here's my suggestion. I remember Massimo did a Reddit clone once. Let's redo this. This will be a hit if done right (the political climate is right :-)). The Reddit clone should show these: 1. Expressiveness and conciseness of Web2py. 2. Exhibition of included batteries: form, authentication, permission, DAL and CRUD. 3. Scalability. There are many frameworks that will take 2 of these 3 items. A good microframework will take 1 and 3 easily. I think Web2py can leverage itself to take all 3 items. Items 1+2 can be easily shown. But item 3 will take a thoughtful experimental design to show. And it might cost some money (but probability not much).Item 3 encapsulates many practical aspects, including deployment. Possibly, choose a fast server like nginx, fine tune the set up to produce optimal results. And if possible, set up a scenario multiple replicated databases. I believe this demonstration will be far better than the mere words of advocacy for web2py. The benefits are multi-fold and will affect new comers and current users (many of whom, I think, are still struggling or at least tweaking with optimal, scalable deployment of web2py apps). Nobody expects that this Reddit clone will replace Reddit (for instance). Fortunately (or unfortunately), not many real apps will have the problem of breaking Reddit frequently is having. But, many people will jump in if they see that Web2py is productive, easy and able to build decently scalable apps.

There is no need to hijack other frameworks' threads. For the record. Our thread was hijacked by both Flask and Django. http://www.reddit.com/r/programming/comments/g875i/building_a_minimalist_facebook_clone_and/c1lnyu8 http://www.reddit.com/r/programming/comments/g875i/building_a_minimalist_facebook_clone_and/c1lqq In the last year - as far as I remember - I only intervened in threads about general discussion on web frameworks OR to clarify incorrect statements made by somebody else about web2py OR after at least two other frameworks were already mentioned and it turned into a discussions about web frameworks. The most recent attack came from an anonymous user who never posted anything else but negative comments on web2py. I find it odd. Anyway typical issues people bring up are: # exec we do it for a reason: in fact, we are the only framework to allow hot install, and uninstall of apps in production and without having sys.path conflict between modules of different apps. the way it is done does not pose any security risk: we do not exec users'input, only serverside code. Other frameworks do module reloading. That only works with Python web servers. That has problems like potential memory leaks (if imported module instantiates an object with a __del__ method and a self reference). # implicit imports Rails does it too, and it is considered good. Enthought python does it too and it is considered a flagship product by the python community. # models and controllers are not python modules No, they are not. Templates are not python modules in any framework, why should models and controllers be? They are not Ruby modules in Rails. That is because they also require a context to run: the http request. # web2py is a Domain Specific Language If it were, there would be nothing bad. Yet, it is not. We use pure Python language everywhere as opposed to other frameworks who indeed use a domain specific language (not python) for configuration files and yet another for templates. # we by-pass normal imports No. we have implicit imports (as mentioned above) and they are well documented. web2py supports normal imports as any other python program. We also have an additional method called local_import as a convenience shortcut to avoid problems with the fact that sys.path is not thread safe. # web2py is not packaged as other web framework True. We will change that. Yet the current packaging is particularly convenient to new users. Some assume that because we ship all modules together, those modules do not work independently outside web2py but, in fact, they do. # web2py is not perfect True. Nothing is. It may not be for everybody. If it is not for you do not use but do not complain about the people who made it available to you for free. # we attack other frameworks Never. At most we pointed out that some of them do not seem to take usability for new users at heart and we think that is important. Being easy to use means lower development and maintenance costs. I also think that some of them do a veyr poor job at backward compatibility but I do not think I ever pointed that out outside this list. Massimo

We want to create an new layout algorithm for biochemical reaction networks, a visualization of the reaction network using SVG and SBGN and a web based (js) SVG editor for the reaction networks. One of the software tools that we would need is a communication layer that brings the graph visualization to the browser. Since we develop a lot of software in our group with the help of web2py it would be great if one of you would be interested in helping us to achieve our vision. The work will have to be done within two month during the summer and you would get payed a nice amount of money by google.

And those who scream the most are not agnostic users looking for the best tool for the job. They are people with something at stake in the relative success of web framework (and I guess I am one these people). With two exception (one being me) these people are not even the creators of the framework they try to bolster, they just act as such and make profit from it. I do not blame them either. Only three things bother me: - when people make false statements - when people who have a professional responsibility within the Python community make statements that are divisive and not inclusive (luckily this is very rare) - when people accuse me (or somebody else) of doing what they do.

[web2py] Re: can web2py internal webserver handle serveral requests in parallel?
To answer simply, yes the embedded Rocket server will handle multiple simultaneous requests. However, if you have long-running processes, they may force Rocket to wait until they are finished before responding to additional requests. This is easy to overcome by using Python's multiprocess module. For example, I have a script to batch insert a bunch of records into the database. The script takes about a minute to run and is started by an ajax call. So in web2py, I created a scripts.py module and imports multiprocessing, then subclasses the Process class. When the ajax call comes in, web2py instantiates my script module, then calls run() to start a new process that does all the work. The moment that run() is called, execution continues so that other incoming requests can be handled and the script runs in the background. Just for fun, I also made my script report progress so that another ajax call could get the status of it.

[web2py] web2py default application suggestion
I'm fairly new to web2py and had a question early on. How could I make a app I created in web2py show up by default. Not that I didn't like the welcome app but I wanted to set my own as default. Somebody in IRC #web2py told me to rename my app to init which worked. There wasn't a way I saw in the web admin to do that so I just did it in the commandline. So based on that experience to make it easier I would suggest the following: 1) In the admin allow users to rename applications 2) in the admin allow users to select a default application. I think that would be nicer than renaming a app with a useful name to init. Thanks for taking the time.

[web2py] How do I set web2py applications as separate virtualhosts?
Web2py works great for me through Apache and mod_wsgi. All seems fast and clean. But now that I'm creating multiple web2py applications. How can I deploy multiple web2py applications as separate virtualhosts? Basically I want to do something like: app1.mydomain.com goes to App1 app2.mydomain.com goes to App2 etc Normally in Apache I would create separate virtualhost directives and point them to the directory where the code is.

Re: [web2py] static subdirectories
Would there be any way to support something like: /$user/app/controller/function Where $user is available to controllers as some sort of arg? I could see your idea about re-formatting the URL to: /app/controller/function/$user but am wondering if that will be hard to manage?
[web2py] Re: web2py default application suggestion
I had a similar question as you a few weeks ago. I can tell you that the reason why admin doesn't allow you to select a default application is because admin would have to edit routes.py, which could break everything if not done right and it also requires a server restart, so that's why no one has added that functionality. Setting the name of your app to 'init' is the easiest way to make it default. Although if you want to keep your application's name, you can create or modify routes.py in the web2py folder (not your application folder) with the following contents: routers = dict( BASE = dict( default_application='MyApp', ) ) Obviously, you'd want to replace MyApp with your application's name. Be sure to restart the web2py server for the changes to take effect. You should now be able to go to http://127.0.0.1:8000 which should take you to your application's default/index.

[web2py] Re: reddit again
It definitely would be nice if we could point to at least one high volume web2py-based site. A Reddit/Digg/HackerNews-type site might make sense. Although I'm wondering if we would be able to get much traffic? It also would be nice if we had some core apps available such as CMS, Blog, Forums, Wiki. If we had a Wiki, we could use it for slices. It would be nice if the book and/or the book app was open-sourced and/or forkable.

Except that you have to be careful when you accuse people of making false statements. For example, pointing out that templates usually aren't python modules either is missing the point.

Just a note, in my default install of web2py there was a router.example.py -AND- routes.example.py In the examples there router.example.py had exactly what you suggested so I tried that and renamed it to router.py which didn't work. I created a new file like you suggested called routes.py which did work. It's kind of confusing with the two examples that don't quite work so I thought I'd mention it. Yes, that is confusing. There are two separate routing systems, as described here: http://web2py.com/book/default/chapter/04#URL-Rewrite. You have to use one or the other -- you can't mix them. 'routes.example.py' includes examples of the older pattern-based system, and 'router.example.py' contains examples of the newer parameter-based system. You would think renaming 'router.example.py' to 'router.py' would be the thing to do, but in fact, regardless of which system you use, you have to rename the file to 'routes.py' (otherwise, if both files existed, web2py wouldn't know which one to use). For clarity, we should probably change the names of the two example files to something like 'routes.pattern_example.py' and 'routes.parameter_example.py' -- that will make it more clear what is in each and that both need to be renamed to 'routes.py'.

Thanks for the feedback. I think the new parameter-based system is probably preferred in general because it's easier, but there are things it cannot do that can only be done with the pattern-based system, so we probably need to maintain good examples for both. But perhaps we could at least include some additional guidance within the example files (e.g., the pattern-based example file could say try the other file first -- use this one only if you need the additional flexibility of the pattern-based system -- and maybe reference the book chapter).

Re: [web2py] Re: web2py applications and version control systems
As I mentioned, with Mercurial or any version control, you can specify the precise version that you want all of the files in the working directory to correspond to. In fact, after doing hg pull, your files will be unchanged. It's not until you hg update that your files actually get updated. And you can specify what changeset or version tag you want to hg update to. For example hg update R-1.94.1. Also, many people do want to try out trunk to verify fixes. With version control, it's very easy to reliably switch back and forth.
[web2py] Re: web2py applications and version control systems
I was just getting ready to dump my newest project into VCS and was wondering the same question. For me, since I'm not anywhere near production yet, I am opting for just putting the application into VCS, then I can use web2py's autoupdate feature. Again, I'm only using this as a playground for putting ideas into code which might be used later on down the line. So the version of web2py upgrading and breaking things is not a concern for me. If you're dealing with a real, life application for a client and you're concerned about the extra files for GAE, I would start my VCS at the base of web2py and only add my application and those files I absolutely needed. The rest could be hg/bzr/git/svn ignore'd. Then you can update just those files and track them, without being bothered by changes to web2py. Again, since I'm only dealing with a sandbox for my own amusement and learning at this time, I'm not really concerned about tracking web2py's updates and matching it for compatibility nor the ability to rollback. --Greg On Mar 17, 1:13 pm, Dave Warnock dwarn...@gmail.com wrote: Hi, Do people generally start version control at web2py/applications/myapp or at web2py?

I think the new parameter-based system is probably preferred in general because it's easier, but there are things it cannot do that can only be done with the pattern-based system, so we probably need to maintain good examples for both. But perhaps we could at least include some additional guidance within the example files (e.g., the pattern-based example file could say try the other file first -- use this one only if you need the additional flexibility of the pattern-based system -- and maybe reference the book chapter). That's a good summary of the situation, including the need to make this clearer in the book. At some point I'd like to enable pattern-editing in the parameter-based router, but I'm not quite sure how to do it. At that point, we could deprecate the pattern-based router, I suppose, though it'd still need to be present for compatibility.

Re: [web2py] Re: web2py default application suggestion
Hi, Just looking again at the book. Is there any support for subdomains in either routing system? I couldn't see any. I am thinking of what I think 37signals use http://clienta.myapp.com/users // list of all users for client A http://clientb.myapp.com/users/dave // form for user dave within client B http://myapp.com/users/// application administrators I am interested both for aesthetics and also because GAE supports namespaces via subdomains for controlling access to the data. Thanks Dave -- Dave Warnock: http://42.blogs.warnock.me.uk Cycling Blog: http://42bikes.warnock.me.uk
Re: [web2py] Re: web2py default application suggestion
All I do to handle sub-domains is check to see if the sub-domain matches a
user sub-domain. For example:
user =
db(db.auth_user.sub_domain==request.env.http_host.split('.')[0]).select().first()
or ''

In the new router, you can configure domain routing in the BASE router. This is
an example from the unit test:
BASE = dict(
domains = {
domain1.com : app1,
www.domain1.com : app1,
domain2.com : app2,
},
),
The domain can include a port, and the target can be a controller:
domains = {
# two domains to the same app
domain1.com : app1,
www.domain1.com : app1,
# same domain, two ports, to two apps
domain2.com : app2a,
domain2.com:8080 : app2b,
# two domains, same app, two controllers
domain3a.com : app3/c3a,
domain3b.com : app3/c3b,
# http vs https
domain6.com:80 : app6,
domain6.com:443 : app6s,
},
But if you want to map the subdomain to (say) an arg, you'll have to use the
regex router.

Hi all,
I find the default javascript validators for integer, double, and decimal
SQLFORM fields to be a little annoying. Consider the following surprising
behaviors:
- You can't navigate within the textbox using the keyboard. Pressing left,
right, home, or end all result in the cursor jumping back to the end of the
input
- You can't select text with ctrl-a or ctrl-shift-left/right
- If the user accidentally flubs the input (e.g. 2.u1828 instead of
2.71828), the offending character is silently removed and an incorrect value
may be submitted without warning.
I think a better alternative is to flag to the user that the input is wrong
rather than trying to correct it for them -- e.g. by changing the input
background color. The following is a sample implementation that does this:
-- in file web2py_ajax.html, replace the lines
jQuery('input.integer').live... and
jQuery('input.double,input.decimal').live... with:
jQuery('input.integer').live('keydown keyup', function(){
if (! this.value.match(/^[+-]?[0-9]*$/)) {
jQuery(this).addClass(w2p_inputerror);
}
else {
jQuery(this).removeClass(w2p_inputerror);
}
});
jQuery('input.double,input.decimal').live('keydown keyup', function(){
if (! this.value.match(/^[+-]?[0-9]*\.?[0-9]*$/)) {
jQuery(this).addClass(w2p_inputerror);
}
else {
jQuery(this).removeClass(w2p_inputerror);
}
});
-- in file base.css, add the following style:
input.w2p_inputerror {
background: #FF8;
}
A few notes:
1. The regexes used to validate numbers are intentionally naive. For
example. the double validator accepts +, -, +., and -., which are of
couse not valid numbers. However, suppose the user enters a value between -1
and 0. They are likely to start by typing -., and I don't think it's
polite to flash the textbox at them when they are about to enter a valid
number.
2. The double validator does not permit scientific notation - e.g. 1e6 for
1 million. Such notation is probably of limited use for most people, the old
validator rejected such values anyway, and I didn't feel like implementing
it :-)
3. The jquery events listen to both keyup and keydown. keyup is necessary
because the input.value has not yet been updated when keydown is fired. But
listening to keydown is useful if the user holds down the backspace key -
the background color will be reset as soon as the last offending character
has been deleted, rather than waiting for the user to release the backspace
key.
4. I used the class name w2p_inputerror in an attept to namespace this
somewhat web2py-specific class.
I hope some people find this to be useful. If other people have been annoyed
by the current default, perhaps we could open discussion to make this the
new default in web2py?

Kevin
[web2py] Re: book other typo
Did anyone have this example working on GAE?
I can get it to come up locally on GAE, but no records that I add show
up in the todo list.
I changed the app.yaml file to:
application: myappname
version: 1
api_version: 1
runtime: python
derived_file_type:
- python_precompiled
handlers:
- url: /
static_files: applications/init/static/output/TodoApp.html
upload: applications/init/static/output/TodoApp.html
- url: /(.*)
static_files: applications/init/static/output/\1
upload: applications/init/static/output/(.+)
- url: /jsonrpc
script: gaehandler.py
My db.py looks like:
try:
from gluon.contrib.gql import * # if running on Google App Engine
except:
db = SQLDB('sqlite://storage.db') # if not, use SQLite or other
DB
else:
db = GQLDB() # connect to Google BigTable
session.connect(request, response, db=db) # and store sessions
there
db=SQLDB('sqlite://storage.db')
db.define_table('todo', db.Field('task'))
from gluon.tools import Service # new in web2py 1.56

[web2py] File Upload and save to DB
HI everyone!! this time I have a new question... I'm developing an application where I generate an INI file (could be any file) with specific info. For example I have this ini structure [Room] name = room1 color = red size = big (I generate the file dynamically from an X computer [x could be any computer running a python script) After the file is generated, is sent by FTP to my web2py server PC in C:\SERVER\iniuploads The question is, how could I read the ini file values and save them in a model?? Some to consider is: - Could be many ini files (each one with the room name, so the name of the file is the same of [Room]) - I need to check every X time if a new ini file has been uploaded, and new files must be processed (save on db) - After a file is processed it must be deleted How could I do this?? It's ok to change the ini to any other file format, what I need is the contained info in a DB.

Thanks for your reply. I had a look at the code, but I am afraid it
doesn't solve my problem. The functions are fields in a table and
depending on their value being true or false they should be rendered
as an a/a or h4/h4 element.
Given this code in a function:
session.id=auth.user.bedrijf_id
session.row=db(db.cardfunction.bedrijf_id==session.id).select(db.cardfunction.ALL)
session.card_menu=[
['Home',request.function=='index',URL(r=request,f='index')],
['Logo',request.function=='logo',URL(r=request,f='logo')],
...
['Keywords',request.function=='keywords',URL(r=request,f='keywords')]]
.. I am looking for a way to make use of the _name attribute, for this
is the same as the field name, something like:
ul
{{for _name,_active,_link in session.card_menu:}}
{{if session.row._name:}}
li
a {{if _active:}} class=active {{pass}}
href={{=_link}}{{=_name}}/a
/li
{{else:}}
li
h4 class=disabled{{=_name}}/h4
/li
{{pass}}
{{pass}}
/ul
The problem is that this: {{if session.row._name:}} results in a
KeyError '_name'
Is it possible to use _name to accomplish this?
I think you want
{{if session.row[0][_name.lower()]:}}
session.row is a Rows object, not a single row, so you have to select
the first one, hence [0].
The single row will have the _name key.
Since your menu is using the capitalized version of the field name I
added _name.lower() so that it would get the correct field name.
Kind regards,
Annet.
