[web2py] Shortcut for fetching a row
According to the book, for what I understand record = db(db.owner.name=='test').select(db.owner.id).first() could be shortcut with record = db.owner(id, name='test') But the latter return None. How can I shortcut the first statement properly? Thank you so very much.

[web2py] Authorization decorators always generate db queries
Hi,
I think we found a serious bug (at least, we hope it is not a designed
feature). If you create a simple controller (like test.py) with the
following actions:
def test():
return dict()
@auth.requires_permission('foo bar')
def test2():
return dict()
And a simple view (like test.html) with:
{{extend 'layout.html'}}
h1Test/h1
{{=response.toolbar()}}
And then open the first action ( app/test/test ) in your browser and
inspect the db stats from the response toolbar, you'll see:
SELECT auth_permission.group_id FROM auth_permission WHERE
(((auth_permission.name = 'foo bar') AND (auth_permission.table_name =
'')) AND (auth_permission.record_id = 0));
If you comment out the decorator, there are no db queries. So this
means that somehow all decorators are executed and because the do
check the database you will get unnecessary database queries. If you
have a controller file with for example 10 actions and all of them
have a auth decorator, you will at least get 10 queries for this
simple single request. We noticed this because I had multiple
decorated actions in one controller file and we got about 30 db
queries for a simple request (like test above). Most of the queries
were of course even duplicates, because of the same decorator.
We noticed this behavior on Version 1.99.2 (2011-09-26 06:55:33)
stable and Version 1.99.3 (2011-11-16 22:36:13) dev
I think this should be fixed, because this will result in unnecessary
bad performance in larger apps.
Regards,
Ids
[web2py] help on rewrite
Hi @all,
I have a small problem with routes.py and the routes_onerror
parameter.
Basically I have one and only application mounted in the webserver
and I'd like to strip the application part from all urls.
Leave alone the redirections for static folder, favicon, robots,
sitemap etc, this is done wonderfully setting:
routes_in = (
('/(?Pany.*)', '/appname/\gany')
)
routes_out = (
('/appname/(?Pany.*)', '/\gany')
)
Now, let's say I want to display a simple page instead of the default
error page.
routes_onerror = [
('*/*', '/errors/index')
]
Working perfectly fine this one also.
I created a simple errors controller, with an index() function in
it, and created a view /errors/index.html.
Request.vars is populated accordingly to the errors, so I can change
the content of the page dinamically, there's only a small problem: if
I try to change the response.status code (if there's a 404 Not Found
it's not polite to return a 200 OK status) rewrite kicks in and
loops forever.
Any hints on how to achieve the same result with different parameters,
if this is not a bug ?

What does your /errors/index function look like? Also, is that your exact
routes_onerror? I ask because there is a bug (now fixed in trunk) that
leads to a loop if your routes_onerror path is missing the leading '/'
(i.e., 'errors/index' would create a loop, whereas '/errors/index' would
not).

Perhaps the book could be more clear. record = db.owner(id, name='test') is a shortcut for: record = db((db.owner.id == id) (db.owner.name == 'test')).select().first() In other words, the first argument to db.owner(...) can simply be the id of the record you want to fetch.

[web2py] Re: help on rewrite
Hi Anthony, /errors/index function is a simple:
def index():
#response.status = request.vars.code
return dict(vars=request.vars)
Notice the response.status line commented, it's the one triggering the
loop.
The template is very simple, in fact I simulated all kinds of error
and it gets rendered correctly. It's only setting the status on the
controller (the commented line in the index() function) that triggers
the infinite loop.
routes_onerror is exactly as reported, with the leading '/'.
BTW, I'm using 1.99.2

Sure, but if I hit request A in a browser, I do not expect any decorators on action B to hit the database.

[web2py] GAE (AppEngine) Datastore models under web2py - can they coexist?
I invested a year in a pure GAE (AppEngine) project, needed to have auth and after much research decided to switch to web2py. This full stack framework blew me away! It is so simple and powerful, but it needs learning. My plan is to switch gradually to web2py because I have paying customers and other waiting to subscribe which I am holding on. One part of quick switching is replacing the Django templates I use with web2py. That part is relatively easy. The product is developed entirely for mobile using jQuery Mobile. It has the capability to run on desktop too but Internet Explorer creates issues - clicking on buttons and submit does not fires always. I believe web2py addresses this - I created layout_mobile.html template based on layout.html which has IE related code and tested it - it seems to work. But the main part is I have to use the native AppEngine Datastore because my database models and code is optimized and tested for thousand users for which Datastore is very good - nonSQL is very quick on this. The bottom line - how to use the native Google Datastore inside web2py? Are there any nasty incompatibilities? Thanks in advance, Regards, --Constantine

I've been doing this a bit, using web2py's DAL for its auth tables and some web pages, and the Datastore for a faceless JSON-RPC service (through a web2py controller). It seems to work fine. If you look at the Datastore through GAE's inspection tools, you'll see the web2py stuff as entities in the Datastore. I don't think there's likely to be a conflict as long as you keep your namespaces from colliding. Caveat: I don't have this in production.
[web2py] Re: Authorization decorators always generate db queries
But I only expect it to hit the database i.e. execute the permission check, when I request a protected action in a controller. Not if I request an unprotected action. So, using the example above, if I call/request test I DO NOT expect database avtivity, if I call test2 I DO expect database activity. It probably has to do with the way python decorators with parameters work, but these side effects are really bad.

Maybe a better example is this:
def index():
# create public index page stuff
return dict(...)
@auth.requires_permission('administrate users')
def admin_users():
# private stuff
return dict(...)
Opening the index page would still hit the database and request
details about the 'administrate users' permission.The index page is
shown, but you still have an totally unnecessary database query. Add
more similarly protected actions in this controller file and the
request for the index page executes even more database queries.

Further tests reveal that decorators @auth.requires_membership and @auth.requires_permission do hit the database and @auth.requires_login does not hit the database. @auth.requires_login probably only checks a session cookie.

+dlypka * * I am developing web services for already 7 years (SOAP, REST, XML, etc.) using .NET. At this time back in the beginning yes it was the most solid technology to get things working quickly. Now - there are much better technologies. So what you are telling is true - I can confirm that. Currently I am heavy invested in GAE - a year of development of a highly scalable app serving a thousand of users. But it was linked to Google accounts and I realized while it saved my time about auth, users don't like signing up via third party auth like Google. So after a long research I decided to use web2py. I generated my auth also using jQuery Mobile for 30 minutes as a proof of concept. While web2py is completely different from GAE(AppEngine) + Django, actually it was much easier to accomplish this. So I am sold on web2py 100%.

If you are using a database that supports mvcc (Oracle, Postgres, MySQL
with InnoDB tables, possibly others), your first select (of any kind, not
just this query) logically freezes the state of the database, and you will
not see any updates until you start a new transaction (which would happen
by starting the cron job again, but might be done manually).
Lookup ACID trait of databases - you might be seeing the I=Isolated
property in action.
Re: [web2py] Re: Authorization decorators always generate db queries
That is exactly my point, il you go beyond authenticating users, you need db access to do it. usualy you dont need RBAC for all your actions. but if you really do, you can move auth tables to RAM (mysql) Khalil

This and other construct are impossible to achieve the same efficiency

The extra space method is probably a bug (so don't count on it working in the future) -- instead, you can start the function name with two underscores, or make sure the function takes at least one argument (even if it's a dummy argument that isn't used).

Re: [web2py] GAE (AppEngine) Datastore models under web2py - can they coexist?
i doubt there is any documentation on the subject per-se. note that the web2py DAL simply translates the web2py style schema definitions and queries into raw GAE datastore queries. if you get really bored and read the DAL you'll see it's just a wrapper around what you already know. you'll also find that there are some GAE features that are not implemented in the DAL yet. if the web2py models and raw GAE models are all different models there should be no problem. if you are accessing a particular model via GAE and web2py just make sure that the web2py represent and requires are written in such a way that any data that may be inserted by the raw GAE access will not cause them to break. for my largest web2py project (starmakerstudios.com and the associated iphone app that talks to the DB) i do all my day-to-day work with web2py DAL, but schema migrations are often done with raw GAE access. hope that helps. feel free to fire off specific questions. cfh

What I need to do? It is hard to explain but I will tray. On my faculty I need to setup small web for professors and students. Professors can upload files (*.pdf, and possibly some *.zip) and they need to login for putting content - uploading files. Filter is make like SELECT(OPTION(),OPTION()), and I have 4 SELECT (4 drop-down list) From Select and options I use professor name and his id, subject name and subject id ... from professor.id and subject.id and some other parameters I need to create file name... example of my file name in upload folder: professor.id_subject.id_year_number.pdf number is some number like number of row in database or just simply ++ counter year is current year, can be setup from list or from date() The content is not confidential, now is on open FTP, just some lectures from mathematics or other subjects. We have problems with FTP, professors have problem to upload files on FTP (ftp tools are complicated for them - some of professors are old ...)

Re: [web2py] Re: Authorization decorators always generate db queries
The problem isn't with the decorator per se, but with the condition being
evaluated. If you have:
@auth.requires_permission('read')
def secrets():
etc.
that is equivalent to:
@auth.requires(condition=auth.has_permission('read'))
def secrets():
etc.
In this case, the decorator takes an argument (the condition to be
evaluated), and the argument itself is a function call that does a db
query. So, setting up the decorated function ends up running the db query
in auth.has_permission. In trunk, there is a new feature that allows a way
around this -- the condition argument to auth.requires can be a callable,
so you can do:
@auth.requires(lambda: auth.has_permission('read'))
def secrets():
In that case, when the decorator is created, it simply passes the lambda as
the condition, rather than calling auth.has_permission. The lambda doesn't
actually get called until the secrets() function is called.
Perhaps we should change auth.requires_membership and
auth.requires_permission to use lambda in this way.

is there any way that I can get

[web2py] Serving non-uploaded, permission based files
I am starting a web2py app and need some help with the high level design. I am familiar with web2py but how to do what I am after is not immediately clear. My app will take jobs submitted by users that will eventually create CSVs files using a cron script and store them on the server's filesystem. Users will then be able to download their specific CSVs. Should I use the static directory with a subfolder for each user and then authenticate and authorize each user to only access their own folder? Also, since the file was never uploaded how would I go about creating URLs to the files to be downloaded? I'm sure there is a better way of doing this and a point in the right direction would be appreciated. Thanks, Dave
[web2py] Re: Serving non-uploaded, permission based files
You won't be able to restrict access to files in static (they are served without touching the application code). Instead, check out http://web2py.com/book/default/chapter/06#Manual-Uploads.

[web2py] Re: GAE (AppEngine) Datastore - web2py
Thank you! nothing is preventing you from using memcache in this way in web2py. you could port the get_profile() method to web2py with no problem This is a great relief. Actually what is the downside using pure GAE vs. web2py? What will be missing? And I suppose I have just to import the appengine libraries as usual and begin to define the model, etc? Are there any code where this is already done? I will spend a time with Eclipse debugger to understand it better when I am able to run it. I am running it at localhost:8080, the breakpoint comes to gaehandler.wsgiapp, I am placing a breakpoint on my app code but the debugger does not stops there. side question - how do you keep your counter up to date without having write contention on the object? (i'm using sharded counters for some things, but i don't like them) Sharded counters seems too complicated and since counting is an essential function I decided early to increase/descrease when addind/deleting on the spot. Because it is a hierarchical structure when I put the code in a transaction I guarantee its update is valid for this branch of the tree. GAE keeps track for the rest. When there is a contention GAE tries several more times until success. Most of the time I do that in a deferred process and this is configurable - how often to try again, how long to wait till next try, basically it is an exponential back off - it is very sophisticated mechanism on which Google worked a lot of time on to perfect it. Another consideration for hierarchical structure is HRD requires it. So this is essential. I watched the logs and this happened several times, the deferred process keeps trying till there is a success. This is one of the reasons I keep staying with pure GAE - you cannot achieve a scale without it and it is related to Google infrastructure, nothing else.
[web2py] problem while connecting to database when password contains '@'
Hi , While trying to connect to a mysql server I found that the URI string used in DAL() was not parsed properly. I have a '@' in my password and gets parsed first changing the hostname to some non existent value, I tried escaping the '@' but dosen't work. Did anyone have this same problem ? If so can you please help me ? Thanks -Syed
Re: [web2py] GAE (AppEngine) Datastore models under web2py - can they coexist?
if the web2py models and raw GAE models are all different models there should be no problem. Actually the GAE models will stay the same because all the system is already tested and working. I decided to move to web2py when I saw it has auth and I implemented it for 30 minutes including jQuery Mobile layout. Which impressed me and I needed to learn more. So basically how I see it I will use only auth from web2py database all the rest would be GAE. for my largest web2py project (starmakerstudios.com and the associated iphone app that talks to the DB) It looks cool. Does the web2py handles the traffic in a stable way?
[web2py] Eclipse+Pydev+GAE+Debugging
there is a trouble setting the visual Eclipse+PyDev debugger to work with web2py. I got the Eclipse debugger to come to a breakpoint in *applications/welcome/models*/db.py but if I set up a breakpoint in *applications/welcome/controllers*/default.py at *index* the debugger does not stops at the breakpoint. If I insert: import pdb, sys debugger = pdb.Pdb(stdin=sys.__stdin__, stdout=sys.__stdout__) debugger.set_trace() before index, pdb stops there. Why Eclipse debugger cannot stops at controllers?
[web2py] Re: os.js
Jquery and ajax make it pretty close, I think. Response time, it seems to me, is the big issue. Server/network latency can be a problem. Sometimes it just takes a while for the packets to get through, even though the amount of data being exchanged is very small. Of course, you can send a lot of data and show/hide as circumstances require, but then the payload to the browser gets a little big.

[web2py] Re: help on rewrite
The patch is now in trunk -- please test. If you can, it would be helpful
if you could try it out with different types of rewrite rules. Also, try it
using the parameter-based rewrite system, as well as with no rewrite rules
at all (want to make sure we didn't break anything).
FYI, an easier way to strip the application name from your URLs is to use
the parameter-based rewrite system -- put this in routes.py instead of your
routes_in, routes_out:
routers = dict(
BASE = dict(
default_application = 'appname',
),
)
See http://web2py.com/book/default/chapter/04#Parameter-Based-System.
Another option is simply to name your app 'init'.

Hi Anthony, /errors/index function is a simple:
def index():
#response.status = request.vars.code
return dict(vars=request.vars)
Notice the response.status line commented, it's the one triggering the
loop.
The template is very simple, in fact I simulated all kinds of error
and it gets rendered correctly. It's only setting the status on the
controller (the commented line in the index() function) that triggers
the infinite loop.
routes_onerror is exactly as reported, with the leading '/'.
BTW, I'm using 1.99.2

What does your /errors/index function look like? Also, is that your

that
leads to a loop if your routes_onerror path is missing the leading

not).

Hi @all,
I have a small problem with routes.py and the routes_onerror
parameter.
Basically I have one and only application mounted in the
webserver
and I'd like to strip the application part from all urls.
Leave alone the redirections for static folder, favicon, robots,
sitemap etc, this is done wonderfully setting:
routes_in = (
('/(?Pany.*)', '/appname/\gany')
)
routes_out = (
('/appname/(?Pany.*)', '/\gany')
)
Now, let's say I want to display a simple page instead of the
default
error page.
routes_onerror = [
('*/*', '/errors/index')
]
Working perfectly fine this one also.
I created a simple errors controller, with an index() function
in
it, and created a view /errors/index.html.
Request.vars is populated accordingly to the errors, so I can
change
the content of the page dinamically, there's only a small problem:
if
I try to change the response.status code (if there's a 404 Not
Found
it's not polite to return a 200 OK status) rewrite kicks in and
loops forever.
Any hints on how to achieve the same result with different
parameters,
if this is not a bug ?

[web2py] forms and validators
Hello,
I am trying to figure out a way which I can have a select (drop down menu)
form, where based on the option that is selected the rest of the form
validators change. To try and explain it better here's the example I am
trying to work on.
I am working on a web2py powerdns front end (to learn web2py).. In the type
form field I have
TR(Type:, SELECT('A', 'CNAME', '', 'MX', 'NS', 'TXT', _name='type',
value='yes', requires=IS_IN_SET(['A', 'CNAME', '', 'MX', 'NS', 'TXT']))),
If the user selects A from the drop down menu I would like to have
requires=IS_IPV4() for the record type validator.
Is it possible to do that?
Thanks
Jimmy.
[web2py] Re: Custom name for uploaded file
I reed all in online book about upload and forms... Can I make my upload manually, something like: brows_file - upload_to_some_folder. What is happening after I submit button 'upload' - can I have control on this activity. I'm new with Web2Py and Python, but on PHP this is no problem, I make all my code upload form and files go to folders what I chose, and file name is my will same or changed... In Python I see some functions os.rename for renaming files, but it is directly rename file name. Can I have may custom upload form with two way first: sending file to folder - no need for database second: sending data to database - and don'n need to know is file or something else. On download process I can us something like list folder content and make links for download (from file list and database data I will generate links for download) If you have doubts why so complicated, and why I don't use simply way shown in book - answer is: the chairman of department what that files stored as early mentioned...
