Movuca now has an API method called _new_event(event_type, **kwargs), this method inserts anything in timeline. 2. Another API method is Notifier.notify(event_type, **kwargs) Both methods uses event_types as a string key and this key is used to configure texts, icons, images and email templates for that kind of event/notification, you can create many event_types you need. In config (a sqlite database) you have notification_options, you can set some keys and worker can be site, queue, scheduler and celery, if worker is site it means that all notifications are sent at the post time (it is very slow if article has too many subscribers) if worker is queue mail is not sent and mail_sent is set to False on that record, the record stores a Pickled state of the notification to be sent later. In your server you need to start the queue worker: $ python web2py.py -S demo -M -N -R applications/appname/private/notification_worker.py This script can run on background and will check for unsent notifications and send it.

One of my crontroler creates a tar.gz file and returns it to the user.
It works well with the default rocket server but not in my production
environment.
The file is corrupted, actually when a look at the file size it is never
the expected size.

- return open(the_filename,'r+b').read()
- return response.stream(open('the_filename','r+b'))
with the same results.

[web2py] Re: Standalone DAL Usiage - Insert from a Dictionary (vs bulk_insert)
def populate_table(): for row in sdb().select(sdb.mytbl.ALL): # build a dict for tbl insert for fldname in sdb().mytbl.fields: ddict[fldname] = row[fldname] Note, each row of the select result is a web2py Row object (see http://web2py.com/books/default/chapter/29/6#Query,-Set,-Rows), which inherits from dict -- so you generally don't need to convert it to a dict because it already acts like one. If you do need to convert to a dict (which I don't think is necessary in this case), you can convert using the as_dict() method, and you can convert an entire Rows object to a list of dicts via the as_list() method. See http://web2py.com/books/default/chapter/29/6#as_dict-and-as_list. In terms of simplifying the code, it would probably be easiest to just use bulk_insert (which technically inserts one record at a time via a list comprehension): ddb.mytbl.bulk_insert(sdb().select(sdb.mytbl.ALL).as_list()) Note, I'm not sure the .as_list() is necessary with bulk_insert -- it might accept the Rows object without converting to a list of dicts. Finally, to copy the contents of a table from one db to another, another option is the CSV export and import functionality: http://web2py.com/books/default/chapter/29/6#CSV-(one-Table-at-a-time).

[web2py] web2py CRUD example
Hi all
I'm trying to use the CRUD-feature of web2py (1.99.4). At the moment I'm
stuck at invalid view (default/data.html) while accessing
https://localhost/init/default/data/tables.
So far I've created a simple application init and changed the following:
In controllers/default.py I've disabled required_signature (I did not want
to play around with permissions at this time):
@auth.requires_login()
# @auth.requires_signature()
def data(): return dict(form=crud())
In views/default.html I've added a link beneath the message:
{{=A('table',_href=URL('data/tables',user_signature=True))}}
If I follow this link (after authenticating) I just receive the error
message:
invalid view (default/data.html)
I did expect something like a list of tables.
Out of the box there seems to be no default/data.html view.
Do I have to write my own data.html view to test the CRUD functionality? Or
did I do something wrong in the setup?
Regards

[web2py] Redbean-like ORM in web2py
First off, my appreciation to Massimo and the web2py team for working on such a wonderful product. I had used RedBeanPHP ORM (http://redbeanphp.com/) in a recent project on PHP, and I really liked it. It stays true to it's claim - Combine The Simplicity of NoSQL With The Power of SQL. - making development a breeze after some initial learning curve. I thought the web2py ORM was already one of the best, but I was really blown away by RedBean, how efficient and productive it is - * the way it relieves you from specifying the schema during development * the way it helps you associate different objects without having to worry about foreign keys and complicated JOIN * the way it lets you mix in the power of SQL to fine-tune your query without proprietary/arcane AND/OR constructs There has been a POC implementation in Python: http://pypi.python.org/pypi/pybean which supports SQLite, but looking at it's description, is not meant for primetime yet. So my question is, is there a plan to implement these RedBean-like features in web2py? It can only make development in web2py more productive and efficient.
[web2py] Re: Redbean-like ORM in web2py
I don't know about future development plans, but I can say that web2py does not use an ORM, it uses a database abstraction layer that generates the proper SQL (and NoSQL) code. Lack of an ORM is sometimes touted as a feature of web2py because ORMs are usually big, complicated, and difficult to learn and maintain. Web2py's DAL is about the simplest, yet most powerful database abstraction layer I've ever used, so I'm very happy with the current solution. However, there is nothing stopping you from using RedBrean or even SQLAlchemy in your web2py projects.
Re: [web2py] Web2py in large web scenarios
This is very good advice. I have moved many of my plugins and apps from using models to modules because of the performance gain. There is nothing wrong with the models implementation, but it's really meant to define tables and that's it. Functionality that doesn't belong in a controller should go to modules. Some other advice that I have been gathering for my own deployments is to use Nginx instead of Apache. You will see an incredible increase in the number of requests per second that Nginx can handle over Apache. Also setting up an Nginx front-facing server that is proxying requests to another server running Nginx + web2py might be a good idea for lots of traffic. Have the front-facing server handle the SSL traffic, and maybe even enable caching on the front-end as well. When you need to add another server to handle increased traffic, this front-facing Nginx server can be configured to load balance so that you can scale as much as you need.

One other thing I noticed after reading your question a second time: Python (Django and web2py) will run much faster than PHP in almost every case.

Re: [web2py] Cherokee deployment config
I know it is not fcgi but I suggest scgi, it is simpler and couples very well with web2py. In the new web2py cookbook there is a recipe for using cherokee with scgi, there you will find a detailed setup description. The essence is that you create an scgi handler in cherokee. You set cherokee to use scgihandler.py inside the root of web2py as startup process in that same scgihandler. Then you are done. Else use nginx it is excellent see this: http://www.web2pyslices.com/slices/take_slice/143 There you see a simplified setup. In production I suggest to use daemontools to manage the scgihandler process: works like a charm. mic p.s. ;-) good thing you can't use apache+wsgi with cherokee+scgi my system is able to handle 5 times more requests (with session.forget()) ;-) 2012/1/27 Roberto Perdomo roberto...@gmail.com: Hi, I have problems with the configuration of a server cherokee with we2py.

Re: [web2py] Web2py in large web scenarios
Are there any good instructions for how to do this?
[web2py] Re: Web2py in large web scenarios
1. It's much easier to scale than it is to gain enough users where scaling is a problem. 2. The framework is almost never the culprit. For example, Disqus has 500 million monthly uniques on Django. 3. There are lots of ways to optimize system performance from caching, to optimizing queries, to refactoring, to upgrading ram/cpu, etc. 4. In most cases, only a tiny percentage of users will be on at the same time so several thousand users should be pretty easy for most frameworks to handle.
[web2py] Re: Redbean-like ORM in web2py
Is the main benefit not having to pre-define models? I suppose that could be nice during development but don't find that to be a big problem with DAL. DAL is pretty integral to Web2py and one of the most popular features. And it has many of the same advantages as RedBean and from my brief look, appears much easier to understand. It's hard to see how something like RedBean would be incorporated. I suppose there's nothing stopping one from trying to create some sort of module or add-on.

Re: [web2py] Web2py in large web scenarios
About db bottlenecks: I think that using executesql gives a performance gain of 2 orders of magnitude over DAL on datasets with more than 1000 records. The DAL is a huge bottleneck if used inappropriately. I suggest using posgtresql with proper indexing. How? Just take your query and run it inside an EXPLAIN statement, see where indexes are needed and *create those indexes*. Speed improvements are *dramatic*. Pass to the DAL only small datasets: even if python has the best sorting and filtering algorithms around (no kidding), postgresql having those same algorithims is simply faster, because of the way objects are handled in memory. When Massimo says the db is the bottleneck, he does not mean that relational DBs are slow in general, IMHO he means that _your_ DB is slow, badly designed and/or badly queried. I also suggest to pay attention to one more thing. When you write the application and you do some test you do it in a quasi-singlethreaded setup. Well everything works fine. Then you go in production and after you reach 20 hits/sec your db becomes a bottleneck whatever hardware you have. If you are using postgresql use a concurrency model based on procesess, *avoid threads*. i.e. configure web2py to work as uwsgi, scgi or fcgi service. mic 2012/1/27 Vinicius Assef vinicius...@gmail.com: It really depends.

DAL provides .sort .find .exclude and Python has a lot of good things like map, reduce, filter. With one db request you can fetch records put them in cache and use Python in some cases to avoid more sql queries. Even paginations can be done without the need to go to db again. Redis is being a good cache solution. http://zerp.ly/rochacbruno Em 27/01/2012 13:40, Alfonso de la Guarda alfons...@gmail.com escreveu: Hi, I'm about to start a major project development and although I am a regular user of web2py in my development, they have been mostly in intranets, what worries me is if anyone has had previous experience of putting an application based on web2py with several thousand users, in which case I would like your job with this. Previously, I have dealt with a project based on django super (50 unique users month) and problems of performance, scalability and others were so serious that they chose to pass it to php, I would not do the same with this application in web2py.

Re: [web2py] Web2py in large web scenarios
I am using /models just to define small global functions and to set some response and request keys. All my code including datamodels I am putting into /modules In my mind I changed the /models to /scripts or /batches so it is more easy to understand why avoiding it. my current structure is: /modules/datamodels/someentity.py - Database definitions /modules/handlers/someentity.py - my code logic and template rendering /modules/helpers/* - miscelanious /modules/myappname.py - My.custom Auth, db, Mail, Service etc.. /controllers/someentytity.py - it will just be a point of entry, here I do selective imports, intantiate the entities and call the template rendering. views files can be stored anywhere filesystem or database. http://zerp.ly/rochacbruno Em 27/01/2012 17:48, Magnitus eric_vallee2...@yahoo.ca escreveu: This is very good advice.

Re: [web2py] Web2py in large web scenarios
What confuses me is what modules have access to and what needs to be imported (in modules and controllers).
Re: [web2py] Web2py in large web scenarios
I wonder if DAL should have an ability to return JSON data sets that are then manipulated with JavaScript? Or something like that?
Re: [web2py] Cherokee deployment config
Thank for you suggest. The next monday i try. Today with cherokee and fastcgi the welcome app work fine, but only show the index, and with other apps is the same problem. El 27/01/2012 16:15, Michele Comitini michele.comit...@gmail.com escribió: I know it is not fcgi but I suggest scgi, it is simpler and couples very well with web2py. In the new web2py cookbook there is a recipe for using cherokee with scgi, there you will find a detailed setup description. The essence is that you create an scgi handler in cherokee. You set cherokee to use scgihandler.py inside the root of web2py as startup process in that same scgihandler. Then you are done. Else use nginx it is excellent see this: http://www.web2pyslices.com/slices/take_slice/143 There you see a simplified setup. In production I suggest to use daemontools to manage the scgihandler process: works like a charm. mic p.s. ;-) good thing you can't use apache+wsgi with cherokee+scgi my system is able to handle 5 times more requests (with session.forget()) ;-) 2012/1/27 Roberto Perdomo roberto...@gmail.com: Hi, I have problems with the configuration of a server cherokee with we2py. I follow the Cherokee with FastCGI manual from: http://www.web2py.com/books/default/chapter/29/13. 1) create the file /var/web2py/startweb2py.sh and set as executable with this content: #!/bin/sh sudo -u www-data python /var/web2py/fcgihandler.fcgi 2) enter in cherokee-admin al port 9090 and config sources with: Nick: web2py Connection: /tmp/fcgi.sock Interpreter: /var/web2py/startweb2py.sh 3) edit vserver default handler with fastcgi and FastCGI Specific set round robin and Assign Information Sources to web2py source before start cherokee server, execute startweb2py.sh and enter to mi ip in the webbrowser al show the startpage from cherokee, i use mi ip/web2py and show error 404. what is wrong? I also try lighttp but the configuration not was successfull. PD: i cant use apache
Re: [web2py] Web2py in large web scenarios
Hi, Nice Bruno, But those approachs how many traffic deals? By the way, is the first time that i notice about use the /modules approach to gain performance, are you measure the performance por models inside /model and /modules? To all: Mores experiences? Problem resolutions? Maybe put all of this inside a document will be great for help to many users when scalability is their minds.

Alan, than you very much! Totally new concept for me, but you got exactly what I needed. I just fixed couple typos, and copying it here in case someone else needs to resolve a similar problem. rows = db(db.purchase_order.id0).select(db.purchase_order.po_number, db.item.id, left=db.item.on(db.purchase_order.id==db.item.po_id)) order_numbers = set([row.purchase_order.po_number for row in rows]) new_data = [[number,] + [str(row.item.id) for row in rows if row.purchase_order.po_number == number] for number in order_numbers] # print new_data # result: [['201201009', 291L], ['201201006', 261L], ['201201004', 161L, 171L], ['201201003', 151L, 231L], ['201201002', 111L, 211L], ['201201001', 31L, 41L, 51L, 61L]] new_data.insert(0, [purchase_order.po_number,]) max_fields = max([len(row) for row in new_data]) csv_output = for row in new_data: extra_fields = max_fields - len(row) csv_output += ,.join(row) + , * extra_fields + \n print csv_output #purchase_order.po_number #201201009,291,,, #201201006,261,,, #201201004,161,171,, #201201003,151,231,, #201201002,111,211,, #201201001,31,41,51,61 Thanks, Adnan
